BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to a method and composition thereof for increasing the milk production in dairy cattle.

Increasing the milk production of lactating dairy cattle is an ongoing challenge facing the dairy industry. The challenge is complicated by the fact that, even though a dairy cow's diet can meet her requirement for crude protein, she may still lack some essential amino acids at the levels required for high milk production. One cause of this dilemma is the digestive system of the dairy cow herself.

Ingested feed first passes into the reticulorumen, where it is subject to anaerobic microbial 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 host animal subsequently meets her own nutrient needs by utilizing the by-products of this extensive fermentation, along with any undigested feed residues and the resultant microbial mass that passes from the rumen.

This microbial activity is certainly an advantage to the ruminant, because it allows them to benefit from feeds for which there is little competition from non-ruminants. However, the microbial intervention limits our ability to provide supplemental nutrients to the ruminant, because many desirable nutrients, such as proteins and amino acids, will be metabolized before they reach a site where they can be absorbed and utilized by the host animal.

A large portion of dietary protein is broken down in the rumen to soluble peptides and amino acids. Some of these peptides and amino acids are utilized by the microbial population directly, but most are further degraded to form ammonia. This ammonia is then used by the microbial population for de novo synthesis of amino acids to meet their own needs. In many cases, this microbial intervention results in the improvement of the amino acid profile being offered to the host.

Many techniques, formulations and the like have been tried in the past to protect the useful products from further degradation in the rumen. Encapsulation of methionine is discussed in Neudoerffer, Duncan and Horney, "The Extent of Release of Encapsulated Methionine in the Intestine of Cattle," 25 British Journal of Nutrition, p.333-341 (1971). Another method that has been tried is to supplement the feed with fatty acids in the form of calcium salts without reducing fiber digestibility, which is disclosed in U.S. Pat. No. 4,642,317 to Palmquist et al. In U.S. Pat. No. 4,248,899 to Lyon et al., a feed supplement is prepared from protein extracted from a leafy green source. The protein is then combined with a triglyceride lipid material.

These methods involve extensive processing. It is highly desirable to have a more simple, economical and productive method for supplying sufficient quantities of essential amino acids in the proper balance to the small intestines where absorption takes place.

SUMMARY OF THE INVENTION

This invention relates generally to a method and composition thereof for increasing the milk production in dairy cattle. By feeding the cattle a particular feed composition which delivers an improved balance of essential amino acids post-ruminally, the cow's milk production is increased. This invention provides a unique approach to feed formulation. The invention is a formulation of dairy feedstuffs, balanced to deliver necessary amino acid requirements at a particular point in the cow's digestive system, rather than, as in the past, just attempting to meet crude protein requirements of the animal. By properly adjusting a particular feed composition to deliver essential amino acids in balance post-ruminally, overall production is enhanced and deficiencies and excesses are minimized.

The composition can be used in several forms: complete feed form, concentrate form, blender form and base mix form. If the composition is in the form of a complete feed, the percent protein level is about 14 to about 24 percent; whereas, if the composition is in the form of a concentrate, the protein level is about 32 to about 48, percent, if the composition is in the form of a blender, the protein level in the composition is about 24 to about 26 percent; and if the composition is in the form of a base mix, the protein level in the composition is about 55 to about 65 percent.

The complete feed form composition generally contains wheat middlings, corn, soybean meal, corn gluten meal, distillers grains or distillers grains with solubles, blood meal, salt, macro-minerals, trace minerals and vitamins. Alternative ingredients would commonly include, but not be restricted to, meat and bone meal, fat, sunflower meal, malt sprouts and soybean hulls.

The concentrate form composition generally contains wheat middlings, corn, soybean meal, corn gluten meal, distillers grains or distillers grains with solubles, blood meal, salt, macro-minerals, trace minerals and vitamins. Alternative ingredients would commonly include, but not be restricted to, meat and bone meal, fat, sunflower meal and malt sprouts.

The blender form composition generally contains wheat middlings, corn gluten meal, distillers grains or distillers grains with solubles, blood meal, salt, macro-minerals, trace minerals and vitamins. Alternative ingredients would commonly include, but not be restricted to, meat and bone meal, corn, soybean meal, fat, sunflower meal, malt sprouts and soybean hulls.

The base form composition generally contains wheat middlings, corn gluten meal, distillers grains or distillers grain with solubles and blood meal. Alternative ingredients would commonly include, but are not restricted to, soybean meal, meat and bone meal, sunflower meal, malt sprouts, fat, macro-minerals, trace-minerals and vitamins.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention herein is a method and composition therefore for increasing milk production in dairy cattle.

By feeding this particular composition to ruminants, essential amino acids are delivered post-ruminally in a particular balance. The key amino acids are lysine, methionine, histidine and phenylalanine. These amino acids are delivered post-ruminally to the abomasum, at which point they are subjected to mammalian digestion that would result in their being absorbed and made available to the mammary gland in proper quantities and proportions to support enhanced milk production.

The composition can be used in several forms: complete feed form, concentrate form, blender form and base mix form. By complete feed form it is meant that the feed represents the cow's entire grain ration. By concentrate form it is meant that the feed will be used as the primary supplemental protein source and would normally be fed with grain to meet the cow's protein needs. By blender form it is meant that the feed will be mixed in approximately a 50:50 ratio with grain to form the complete grain ration. The base mix form is similar to the concentrate form, but is typically higher in protein content and is used at lower inclusion rates. The base mix form will be a primary, but often not the sole source of supplemental protein.

The grains fed with the blender, concentrate and base mix forms of the composition include, but are not limited to, corn, barley, oats, millet, rice, sorghum and wheat, and intakes of the total grain ration will typically range from 6 to about 37 lbs./day.

If the composition is in the complete feed form, the percent protein level is about 14 to about 24 percent; whereas, if the composition is in the form of a concentrate, the protein level is about 32 to about 48 percent; if the composition is in the form of a blender, the protein level in the composition is about 24 to about 26 percent; and if the composition is in the form of a base mix, the protein level in the composition is about 55 to about 65 percent.

Total supply of the key essential amino acids post-ruminally, whether the ration is based upon the complete feed form, the concentrate form, the blender form or base form of the invention, should be in the amount of about 69 to about 332 grams/day lysine, about 20 to 105 grams/day methionine, about 22 to 113 grams/day histidine, and about 44 to 225 grams/day phenylalanine. These requirements will depend upon body weight and level of production as shown in Table 1 and the following equations:

Lysine requirement (g)=8.23 +(147.13 ×MP) +(0.02458 ×BW);

Methionine requirement (g)=1.8017 +(47.244 ×MP) +(0.00558 ×BW);

Histidine requirement (g)=2.348 +(50.514 ×MP) +(0.007166 ×BW); and

Phenylalanine require (g)=3.883 +(101.62 × MP) +(0.01216 ×BW);

Where: MP=Kg. milk protein

BW=Kg. body weight.

This requirement can be met by essential amino acids from two sources, protein of microbial origin, which was synthesized in the rumen, and from undegraded intake protein. Microbial crude protein (MCP) synthesis is primarily a function of microbial growth, which in turn is dependent upon the amount of fermentable energy in the diet. The level of fermentable energy can be estimated using the method of Tilley and Terry, "A Two Stage Technique for the In Vitro Digestion of Forage Crope," J. of the British Grassland Society. 18:104-111 (1963). This fermentable energy can be expressed as non-fat net energy of lactation (NFNE₁). The technique referenced above can be applied to determine the amount of net energy of lactation (NE₁) that the total daily ration provides from components other than fat, that is, non-fat net energy of lactation. It is important to exclude fat, since the rumen microbial population can derive little energy from fat to support their growth. This value for NFNE₁ (Mcal/kg) can then be applied to estimate microbial amino acid flow as follows:

MCP (g)=6.25 ×(-19.374 +(12.52 ×NFNE1)).

Only 80 percent of MCP is estimated to be true amino acid protein, so microbial amino acids (MAA) production would be:

MAA (g)=0.8 ×MCP.

To estimate the flow of individual amino acids of microbial origin, the amino acid composition of microbial protein is applied to the estimate of total MAA. Microbial protein is approximately 9.30 grams/100 g lysine, approximately 2.60 grams/100 g methionine, approximately 2.30 grams/100 g histidine and approximately 5.0 grams/100 g phenylalanine. The quantity of essential amino acids that pass into the duadenum rumen from undegraded intake protein can be estimated using techniques described by Craig and Broderick, "Amino Acids Released During Protein Degradation By Rumen Microbes," Journal of Animal Science 58:436-443 (1984). Both of these techniques are used and incorporated herein by reference.

If fat is used, it is employed in an amount of greater than zero to about 3.5 weight percent. Malt sprouts are used in the amount of about greater than zero to about 30 weight percent. The soybean hulls are used in an amount of about greater than zero to about 10 weight percent.

The concentrate form of the composition contains about 18 to about 50 weight percent wheat middlings, about 3.0 to about 16.0 weight percent soybean meal, about 2.5 to about 6.0 weight percent macro-minerals, about 10 to about 20 weight percent distillers grains or distillers grains with solubles, about 0.3 to about 0.5 weight percent trace minerals, about 10.0 to about 28.0 weight percent blood meal and about 5.0 to about 18.0 weight percent corn gluten meal.

It should be noted that there are four primary methods to produce blood meal, which are the following: ring drying, flash drying, cook or vat drying and spray drying. Ring and flash dried blood meal are the most consistent in quality of those types suitable to deliver key essential amino acids pot-ruminally and are preferably used.

When the composition is fed in conjunction with a roughage base of corn silage versus legume or grass, the composition can be adjusted to best compliment the small differences in essential amino acid flow that result from the digestion of these roughage sources. With a predominantly legume or grass roughage base, the post-rumenal methionine supply is less than if corn silage is used. This can be corrected if the proper level of corn gluten meal is used in the composition's formulation, whether it be in the complete feed form, the concentrate form, the blender form or base mix form.

Furthermore, to ensure the increase in milk production, all rations should be properly balanced according to recognized standards put forth in Nutrient Requirements of Dairy Cattle, Sixth Revised Edition (1988), National Research Council, National Academy Press, Washington, D.C. and by Sniffen, et al. (1988) "Balancing for Carbohydrates in Dairy Rations," Proc. 49th Minnesota Nutrition Conference. In addition, sufficient quantities of the composition, whether complete feed form, concentrate form, blender form or base mix form, must be fed to the dairy cattle to achieve a flow of essential amino acids that will meet the requirement previously described.

The composition in the complete feed form generally has a protein amount of about 14 to about 24 weight percent, a fat amount of about 2.0 to about 6.0 weight percent, a fiber maximum of about 12 weight percent, a phosphorus amount of about 0.6 to about 0.9 weight percent, a calcium amount of about 0.9 to about 1.8 weight percent, and total digestible nutrients (TDN) of at least about 71 weight percent.
