Definitions
- the present invention relates to feed additives for ruminants. More particularly, the invention relates to a feed additive composition and method of making comprising a biologically active substance that is coated with a coating composition which minimizes release of the biologically active substance in the rumen, but provides for the primary release of the biologically active substance in the abomasum and subsequent digestive tract of the ruminant animal.
- a ruminant animal originally evolved to allow it to benefit from feeds for which there was little competition from non-ruminants.
- ingested feed is first chewed and then passes into the ruminant's four chambered “stomach.”
- the ruminant's four chambered “stomach” and their functions are now specifically considered.
- the first chamber namely the reticulum, aids in bringing boluses of feed back to the mouth for rechewing. It is also kind of a “drop out box” for heavy objects that the animal may have ingested.
- the chewed, and rechewed feed then passes from the reticulum into the next chamber of the ruminant's stomach, called the rumen, where it is subjected to anaerobic fermentation.
- This microbial fermentation begins the digestive process and gives the ruminant the ability to utilize fibrous feeds that the mammalian system alone cannot break down due to the lack of necessary enzyme systems.
- the ruminant animal subsequently meets its nutrient needs by utilizing the by-products of this extensive fermentation, such as volatile fatty acids, along with any undigested feed residues and the resultant microbial mass that passes from the rumen.
- the normal pH of the rumen is 6 to 7.
- the feed Once the feed has been reduced in size by chewing and digestion by the bacteria and protozoa in the rumen, it passes into the next compartment of the ruminant's stomach called the omasum. Also moving from the rumen to the omasum is a portion of the microbial mass that develops in the rumen. In addition, the omasum absorbs a large portion of the volatile fatty acids that move from the rumen to the omasum because they were not absorbed through the rumen wall. The omasum is also thought to absorb water and electrolytes such as potassium and sodium. The material in the omasum, then passes into the abomasum, the fourth, and final chamber of the ruminant's stomach.
- the abomasum is called the “true” stomach because it functions in a manner very similar to the stomach of a man or a pig.
- the walls of the abomasum secrete enzymes and hydrochloric acid.
- the pH of the digesta coming into the abomasum is about 6 to 7, but is quickly lowered to about 2.5 by the acid. This creates a proper environment for the enzymes to function.
- a primary digestive function of the abomasum is the partial breakdown of proteins.
- the enzyme pepsin is mainly responsible for protein breakdown. Proteins from the feed and the microorganism mass coming from the rumen are broken down into smaller units called peptides before leaving the abomasum.
- digesta are further broken down, proteins into amino acids, starch to glucose, and complex fats into fatty acids.
- the amino acids, glucose and fatty acids are then absorbed in the lower half of the small intestine.
- the digesta leaving the small intestine enters the large intestine where water is absorbed, thus making the digesta more solid.
- Bacteria living in the large intestine work at digesting any feedstuffs which escaped digestion earlier. This usually contributes less than 15% of the total digestion.
- the final step in the ruminant digestive process is excretion from the large intestine.
- U.S. Pat. No. 4,832,967 discloses a composition consisting of a biologically active substance which is stable in a medium whose pH is greater than 5 and which permits release of the substance in a medium whose pH is less than 3.5. This is said to be achieved using a precoating layer, a first coating layer sensitive to pH variations and a second coating layer of a hydrophobic substance.

These and other shortcomings of these compositions and methods are addressed by the present invention.
- the present invention overcomes the problem of moving a biologically active substance through the rumen with little degradation, and yet allows the biologically active substance to be available in the abomasum and subsequent digestive tract for use by the ruminant animal.
- the composition of the invention comprises an inner core of a biologically active substance, preferably being spherical and having a smooth surface; a polyurethane coating surrounding the inner core of the biologically active substance, and a wax coating of the “intermediate type” coating the polyurethane coating which surrounds the inner core.
- the composition of the invention takes advantage of the biological activity of the rumen, abomasum, small intestine, and large intestine.
- the passage of the coated biologically active substance through the rumen exposes the outer wax coating to the rumen contents, which begin to degrade the wax coating.
- the outer wax coating and the inner polyurethane coating serve to protect the core of biologically active substance from the rumen contents, so that the core material is released only minimally during the passage of the coated core through the rumen.
- the wax coating is further degraded. This allows the inner core contents to be released over the time of transit through the abomasum, small intestine, and large intestine, for the benefit of the ruminant animal.

Abstract
Description
- The present invention relates to feed additives for ruminants. More particularly, the invention relates to a feed additive composition and method of making comprising a biologically active substance that is coated with a coating composition which minimizes release of the biologically active substance in the rumen, but provides for the primary release of the biologically active substance in the abomasum and subsequent digestive tract of the ruminant animal.
- Increasing the milk production of lactating dairy cattle, and meat production in cattle raised for meat, is an ongoing challenge to the farmer. It is possible to provide, or even exceed, the crude protein requirements of these animals when seeking higher milk or meat production. However, due to the nature of the ruminant digestive system, it may not be possible to “balance” the higher crude protein intake with essential amino acids or other biologically active substances required for the higher milk or meat output. Unfortunately, direct oral administration of the biologically active substances results in their being decomposed by the microorganisms present in the rumen, which is essentially a very efficient bioreactor.
- More specifically, the digestive system of a ruminant animal originally evolved to allow it to benefit from feeds for which there was little competition from non-ruminants. In a ruminant, ingested feed is first chewed and then passes into the ruminant's four chambered “stomach.” The ruminant's four chambered “stomach” and their functions are now specifically considered. The first chamber, namely the reticulum, aids in bringing boluses of feed back to the mouth for rechewing. It is also kind of a “drop out box” for heavy objects that the animal may have ingested. The chewed, and rechewed feed then passes from the reticulum into the next chamber of the ruminant's stomach, called the rumen, where it is subjected to anaerobic fermentation. This microbial fermentation begins the digestive process and gives the ruminant the ability to utilize fibrous feeds that the mammalian system alone cannot break down due to the lack of necessary enzyme systems. The ruminant animal subsequently meets its nutrient needs by utilizing the by-products of this extensive fermentation, such as volatile fatty acids, along with any undigested feed residues and the resultant microbial mass that passes from the rumen. The normal pH of the rumen is 6 to 7. Once the feed has been reduced in size by chewing and digestion by the bacteria and protozoa in the rumen, it passes into the next compartment of the ruminant's stomach called the omasum. Also moving from the rumen to the omasum is a portion of the microbial mass that develops in the rumen. In addition, the omasum absorbs a large portion of the volatile fatty acids that move from the rumen to the omasum because they were not absorbed through the rumen wall. The omasum is also thought to absorb water and electrolytes such as potassium and sodium. The material in the omasum, then passes into the abomasum, the fourth, and final chamber of the ruminant's stomach. The abomasum is called the “true” stomach because it functions in a manner very similar to the stomach of a man or a pig. The walls of the abomasum secrete enzymes and hydrochloric acid. The pH of the digesta coming into the abomasum is about 6 to 7, but is quickly lowered to about 2.5 by the acid. This creates a proper environment for the enzymes to function. A primary digestive function of the abomasum is the partial breakdown of proteins. The enzyme pepsin is mainly responsible for protein breakdown. Proteins from the feed and the microorganism mass coming from the rumen are broken down into smaller units called peptides before leaving the abomasum.
- The remaining parts of the ruminant digestive system, the small and large intestines, function just as they do in man or pig. In the upper half of the small intestine, digesta are further broken down, proteins into amino acids, starch to glucose, and complex fats into fatty acids. The amino acids, glucose and fatty acids are then absorbed in the lower half of the small intestine. The digesta leaving the small intestine enters the large intestine where water is absorbed, thus making the digesta more solid. Bacteria living in the large intestine work at digesting any feedstuffs which escaped digestion earlier. This usually contributes less than 15% of the total digestion. The final step in the ruminant digestive process is excretion from the large intestine.
- As noted above, modern farmers seek to optimize milk and meat production by feeding the respective cattle an optimum diet. Providing sufficient crude protein in the diet is a relatively straight forward task. However, supplying sufficient quantities of essential amino acids to balance the crude protein intake and promote optimum milk and meat production has proved difficult or not possible. One of the reasons is the design of the ruminant digestive system, and in particular, the breakdown of amino acid compositions in the rumen prior to their reaching the abomasum and small intestine where these essential nutrients can be absorbed in the ruminant's small intestine.
- The prior art discloses various ruminant feed compositions having biologically active substances useful in providing the desired amino acid to the ruminant which are said not to break down in the rumen and provide for release of the substance in the remaining stomachs of the ruminant. For example, U.S. Pat. No. 4,832,967 discloses a composition consisting of a biologically active substance which is stable in a medium whose pH is greater than 5 and which permits release of the substance in a medium whose pH is less than 3.5. This is said to be achieved using a precoating layer, a first coating layer sensitive to pH variations and a second coating layer of a hydrophobic substance.
- Also known is U.S. Pat. No. 5,227,166 which discloses a composition consisting of a biologically active substance and a coating having lecithin, an inorganic substance which is stable under neutral conditions and a specific monocarboxylic acid having 14 to 22 carbon atoms, hardened vegetable oils, hardened animal oils and waxes.
- Further known is U.S. Pat. No. 4,533,557 which discloses tablets or granules of a mixture of a biologically active substance, chitosan and protective materials of saturated or unsaturated aliphatic monocarboxylic acid having 14 to 22 carbon atoms, hardened vegetable oils and hardened animal oils. The chitosan is said to allow the biologically active substance of the composition to pass through the rumen and release in the abomasum.
- Other prior art patents discuss additional compositions as ruminant feed additives including U.S. Pat. Nos. 3,541,204; 3,959,493; 4,595,584; 4,687,676; 4,877,621; 4,983,403; 5,616,339; 5,296,219, and 5,871,773.
- In other fields it has also been recognized that fertilizer and pesticide products can be applied to a soil environment in order to control the release of the fertilizer or pesticide over a period of time. With respect to fertilizers, this permits a single application of the fertilizer which will last several months and possibly an entire growing season, avoiding the need for further applications. For example, U.S. Pat. Nos. 4,716,659; 4,804,403, and 4,969,947, assigned to the assignee of the present application, disclose an attrition-resistant, controlled-release fertilizer comprising a water-soluble central mass, such as urea, containing nucleophilic reaction functional groups surrounding and chemically bonded to a base coating formed by reacting a molecular excess of a coupling agent, such as a polyisocyanate, with the nucleophilic groups of the central mass and a water-insoluble layer surrounding and chemically bonded with the base coating formed by the reaction and polymerization of the excess functional groups of the coupling agent. These products provide outstanding controlled-release fertilizer products. Similarly, U.S. Pat. No. 6,682,751, also assigned to the assignee of the present application, discloses a controlled release pesticide composition and method of making a controlled release pesticide composition providing outstanding controlled-release pesticide products.
- These compositions and methods of the prior art ruminant feeds have various shortcomings including their efficiency in providing amino acid release in the abomasum, they are expensive and/or difficult to manufacture or simply can stand improvement. These and other shortcomings of these compositions and methods are addressed by the present invention.
- The present invention overcomes the problem of moving a biologically active substance through the rumen with little degradation, and yet allows the biologically active substance to be available in the abomasum and subsequent digestive tract for use by the ruminant animal. The composition of the invention comprises an inner core of a biologically active substance, preferably being spherical and having a smooth surface; a polyurethane coating surrounding the inner core of the biologically active substance, and a wax coating of the “intermediate type” coating the polyurethane coating which surrounds the inner core. The composition of the invention takes advantage of the biological activity of the rumen, abomasum, small intestine, and large intestine. The passage of the coated biologically active substance through the rumen exposes the outer wax coating to the rumen contents, which begin to degrade the wax coating. However, the outer wax coating and the inner polyurethane coating serve to protect the core of biologically active substance from the rumen contents, so that the core material is released only minimally during the passage of the coated core through the rumen. As the coated core moves out of the rumen and into the remainder of the animals digestive tract, the wax coating is further degraded. This allows the inner core contents to be released over the time of transit through the abomasum, small intestine, and large intestine, for the benefit of the ruminant animal.
- A primary object of the present invention is to provide a composition having a biologically active substance which will not significantly release in the rumen but will primarily release in the abomasum and subsequent digestive tracts of the ruminant. A preferred biologically active substance is an amino acid, preferably lysine, which will provide for increased milk production in dairy cattle or meat production in meat cattle.
- Another primary object of the present invention is to provide a composition having a biologically active substance having a protective coating which coating prevents significant release of the biologically active substance in the rumen. A preferred coating comprises a first polyurethane coating layer and a second coating layer of an intermediate wax.

A preferred polyurethane coating is formed by a polymeric diphenylmethane diisocyanate and a polymeric polyester polyol blended with triethanolamine.

The wax coating comprises an “intermediate wax.” A presently preferred intermediate wax comprises a wax derived from a high boiling lubricating oil distillate and may have the following characteristics: initial boiling point, ° F.: 718 (° C.: 381.1); drop point, ° F., minimum, via ASTM D-127: 160 (° C.: 71.1); oil content, maximum, %, via ASTM D-1500: 3.0; viscosity, cSt @ 100 C, via ASTM D-445: 7.07-8.53, and needle penetration, in 0.1 mm, maximum, via ASTM D-1321: 14. The wax coating is preferably in the range of about 2 to about 7 micrometers in thickness, and more preferably in the range of about 3 to about 6 micrometers in thickness. It is understood that the thickness of the wax coating may vary depending on the biologically active substance and the polymer coating.
- The following examples illustrate the novelty and benefits of the invention. Example 1 is a comparative example illustrating a composition which does not provide the benefits of the present invention. Examples 2 and 3 disclose preferred compositions of the invention and methods of making the compositions of the invention.
- 3000 grams of granulated lysine, BIOLYS® (Degussa Corporation), average diameter 1.14 mm, were transferred into a stainless steel coating drum which contains lifting and mixing flights and was rotated at 38 revolutions per minute. The 3000 grams of granulated lysine were heated to 175° F. (79.4° C.) using a laboratory heat gun. A first polyurethane coating layer was provided on the lysine as follows:
- 1) 2.8 grams of polymeric MDI (p-MDI) (Mondur® MR Light, Bayer Corporation) were injected into the most active part of the bed of tumbling granules, and 30 seconds were allowed for the p-MDI to evenly spread over the surface of the granules. Then 8.5 grams of a blend of 90% polyester polyol (Terate® 258, Investa Corporation) and 10% triethanolamine, were injected into the most active part of the bed and 60 seconds were allowed for the polyester polyol/triethanolamine to evenly spread over the surface of the granules. At the conclusion of the 60 seconds, 4.3 grams of p-MDI were injected into the most active part of the bed and 30 seconds were allowed for the p-MDI to evenly spread over the surface of the granules. After the conclusion of the 30 second spread time for the p-MDI injection, an additional 60 seconds were allowed to complete the reaction to form the first polyurethane coating layer. The granules were maintained at a temperature of 175° F. (79.4° C.) during this coating process.
- 2) Step (1) was repeated 7 more times to provide a total polyurethane coating of 124.8 grams on the granulated lysine or a coating thickness of approximately 8.8 micrometers.
- 3) At the conclusion of the last polyurethane coating layer, 27 grams of molten Intermediate Wax, CITGO HI-618 wax (Citgo Petroleum Corporation) were injected into the most active part of the bed and 60 seconds were allowed for the wax to spread evenly over the granulated lysine and providing for a wax coating thickness of approximately 3.0 micrometers.
- 4) The coated product was then cooled down to 115° F. (46.1° C.) and removed from the coating drum.
- 5) The resulting coated lysine product has a polyurethane coating of 3.96% (thickness of approximately 8.8 micrometers), and an outer wax coating of 0.86% (thickness of approximately 3.0 micrometers). 20 grams of the coated product were placed in 100 ml of deionized water which was thermostated at 102° F. (38.9° C.), and the release of the lysine was measured over a period of 18 hours. The results of this release test are shown in Table 1 below.
TABLE 1 % Cumulative Hours in test Lysine Release 1 0.0 2 4.3 4 7.5 6 15.3 8 24.5 10 32.7 12 43.4 14 51.3 16 60.8 18 67.8 - 6) The coated product from Example 1 was tested for “rumen bypass” using ruminally cannulated Jersey cows. The product was exposed to the rumen of the cows for 16 hours, and the amount of lysine still present in the coated product was measured. It was found that 18.7% of the lysine originally present was still present at the end of the rumen exposure period. The uncoated lysine granules were also exposed to the rumen in a similar test, and after 16 hours of exposure, 16.5% of the lysine originally present was still present. The difference between the coated and uncoated lysine results was not statistically significant. Thus, the product from Example 1, coated with almost 4% polyurethane, and almost 0.9% intermediate wax, did not yield any better rumen bypass than the uncoated lysine granules.
- 2765 grams of granulated lysine, BIOLYS® (Degussa Corporation), average diameter 1.00 mm, were transferred into a stainless steel coating drum which contains lifting and mixing flights and was rotated at 38 revolutions per minute. The 2765 grams of granulated lysine were heated to 175° F. (79.4° C.) using a laboratory heat gun. A first polyurethane coating layer was provided on the lysine as follows:
- 1) 3.2 grams of polymeric MDI (p-MDI) (Mondur® MR Light, Bayer Corporation) were injected into the most active part of the bed of tumbling granules, and 30 seconds were allowed for the p-MDI to evenly spread over the surface of the granules. Then 7.1 grams of a blend of 90% polyester polyol (Terate® 258, Investa Corporation) and 10% triethanolamine, were injected into the most active part of the bed and 60 seconds were allowed for the polyester polyol/triethanolamine to evenly spread over the surface of the granules. At the conclusion of the 60 seconds, 4.7 grams of p-MDI were injected into the most active part of the bed and 30 seconds were allowed for the p-MDI to evenly spread over the surface of the granules. After the conclusion of the 30 second spread time for the p-MDI injection, an additional 60 seconds were allowed to complete the reaction to form the first polyurethane coating layer. The granules were maintained at a temperature of 175° F. (79.4° C.) during this coating process.
- 2) Step (1) was repeated 15 more times to provide a total polyurethane coating of 240 grams on the granulated lysine or a coating thickness of approximately 16.1 micrometers.
- 3) At the conclusion of the last polyurethane coating layer, 27.7 grams of molten Intermediate Wax, CITGO HI-618 was (Citgo Petroleum Corporation) were injected into the most active part of the bed and 60 seconds were allowed for the wax to spread evenly over the granulated lysine and providing for a wax coating thickness of approximately 3.0 micrometer.
- 4) The coated product was then cooled down to 115° F. (46.1° C.) and removed from the coating drum.
- 5) The resulting coated lysine product has a polyurethane coating of 7.91% (thickness of approximately 16.1 micrometers), and an outer wax coating of 0.91% (thickness of approximately 3.0 micrometers). 20 grams of the coated product were placed in 100 ml of deionized water which was thermostated at 102° F. (38.9° C.), and the release of the lysine was measured over a period of 28 hours. The results of this released test are shown in Table 2 below.
TABLE 2 % Cumulative Hours in test Lysine Release 1 0.0 2 0.0 4 0.0 8 0.0 10 1.3 12 1.9 16 2.2 24 5.1 26 6.3 28 7.8 - 6) The coated lysine product from Example 2 was tested as follows for ruminal and intestinal digestibility.
- Ruminal and intestinal digestibility of the product from Example 2 were determined in a replicated randomized block using three lactating Jersey cows fitted with ruminal and duodenal cannulas. Approximately 10 g of the test product was weighed into a 5 cm×10 cm bags (ANKOM #510, average pore size of 50±15 microns). Each bag was heat sealed twice. Twenty-four bags were prepared plus 12 blanks. Individual bags were placed into a laundry bag by cow and replicate and labeled accordingly. Immediately before insertion into the rumen, bags were soaked in 39° C. (102.2° F.) water for approximately 5 minutes to wet the test material. Bags were inserted in the rumen and removed 16 hours after insertion. Upon removal from the rumen, the bags were immediately placed in ice water until they could be washed three times. The bags were then immediately dried in a forced air oven at 55° C. (131° F.) for 24 hours. The dried bags were weighed and contents composited by treatments within cow and replicate. Ruminal digestibility of the lysine was calculated for each sample.
- Intestinal digestibility was determined by mobile bag technique. Approximately 0.8 g of sample was weighed into the 5×6 cm polyester bag (ANKOM #510 cut to approximately 6 cm in length) and heat sealed twice. A total of sixteen bags for each replicate were prepared for insertion. The bags for the intestinal digestibility phase were soaked in pepsin-HCl solution (100 mg pepsin per liter of 0.01 N HCl) for 2 hours at 39° C. (102.2° F.) in a shaking water bath. Enough HCl was added to decrease pH to 2.4. Upon removal, the bags were rinsed with distilled water and kept at −18° C. (−0.4° F.) until introduction into the duodenum. One bag was inserted into the duodenal cannula each day every 15 minutes following a meal for a three-hour period (total of 12 bags per cow per insertion). Bags were collected from the feces from 8 to 20 hours after initial insertion. Upon recovery, bags were rinsed under tap water until the rinse water was clear. Bags were dried at 55° C. (131° F.) and residue pooled by replicate within cow for analyses of lysine. The results of the animal tests for the product from Example 2 were:
- a) lysine content after 16 hour exposure to rumen=70.1% of amount originally present.
- b) lysine digestibility in intestine=79.2%. Therefore, the amount of lysine that escapes the rumen and is digested in the intestine for the product from Example 2 is
70.1%×0.792=55.5% of amount originally present. - 3000 grams of granulated lysine, BIOLYS® (Degussa Corporation), average diameter 1.10 mm, were transferred into a stainless steel coating drum which contains lifting and mixing flights and was rotated at 38 revolutions per minute. The 3000 grams of granulated lysine were heated to 175° F. (79.4° C.) using a laboratory heat gun. A first polyurethane coating layer was obtained as follows:
- 1) 3.3 grams of polymeric MDI (p-MDI) (Mondur® MR Light, Bayer Corporation) were injected into the most active part of the bed of tumbling granules, and 30 seconds were allowed for the p-MDI to evenly spread over the surface of the granules. Then 7.7 grams of a blend of 90% polyester polyol (Terate® 258, Investa Corporation) and 10% triethanolamine, were injected into the most active part of the bed and 60 seconds were allowed for the polyester polyol/triethanolamine to evenly spread over the surface of the granules. At the conclusion of the 60 seconds, 5.1 grams of p-MDI were injected into the most active part of the bed and 30 seconds were allowed for the p-MDI to evenly spread over the surface of the granules. After the conclusion of the 30 second spread time for the p-MDI injection, an additional 60 seconds were allowed to complete the reaction to form the first polyurethane coating layer. The granules were maintained at a temperature of 175° F. (79.4° C.) during this coating process.
- 2) Step (1) was repeated 14 more times to provide a total polyurethane coating of 241.5 grams on the granulated lysine or a coating thickness of approximately 16.5 micrometers.
- 3) At the conclusion of the last polyurethane coating layer, 45.0 grams of molten Intermediate Wax, CITGO HI-618 wax (Citgo Petroleum Corporation) were injected into the most active part of the bed and 60 seconds were allowed for the wax to spread evenly over the granulated lysine and providing for a wax coating thickness of approximately 4.9 micrometers.
- 4) The coated product was then cooled down to 115° F. (46.1° C.) and removed from the coating drum.
- 5) The resulting coated lysine product has a polyurethane coating of 7.35% (thickness of approximately 16.5 micrometers), and an outer wax coating of 1.37% (thickness of approximately 4.9 micrometers). 20 grams of the coated product were placed in 100 ml of deionized water which was thermostated at 102° F. (38.9° C.), and the release of the lysine was measured over a period of 28 hours. The results of this release test are shown in Table 3 below.
TABLE 3 % Cumulative Hours in test lysine release 1 0.0 2 0.0 4 0.0 6 0.6 8 0.7 10 1.0 12 1.1 16 1.1 24 1.8 48 10.4 - 6) The coated lysine product from Example 3 was tested for ruminal and intestinal digestibility in the same way as was the coated lysine product from Example 2.
- The results of the animal tests for the product from Example 3 were:
- a) lysine content after 16 hours of exposure to rumen=97.6%
- b) lysine digestibility in intestine=62.0%. Therefore, the amount of lysine that escapes the rumen and is digested in the intestine for the product from Example 3=is
97.6%×0.62=60.5% - The above Examples 2 and 3 illustrate the effectiveness of the present invention. The ruminant feed of the present invention provides for a release of the lysine primarily in the abomasum and subsequent digestive tract of the ruminant. It provides for predictability of release and is generally inexpensive and not difficult to manufacture. Thus, an effective composition of the invention comprises a composition which will have a lysine content after about 16 hours exposure to the rumen of at least 60% of amount originally present, and more preferably in the range of about 70% to about 100% of amount originally present.
- The ruminant feed composition of the invention is preferably mixed with other ruminant feed rations. Based on the predictability of the release of the biologically active substance those skilled in the art will be able to determine the appropriate amount of the ruminant feed additive for the ruminant's diet.
- The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. As will be apparent to one skilled in the art, various modifications can be made within the scope of the aforesaid description. Such modifications being within the ability of one skilled in the art form a part of the present invention and are embraced by the appended claims.
