The effect of amino acid feed on animal products is undeniable. Protein is a supporter of life activities of organisms, and protein is composed of amino acids, which means that amino acids are the supporters of biological life activities. This shows the importance of amino acid feed for farm livestock. This article will explore the effects of amino acids on different animals.
Point:
Amino acid feed levels will affect the carcass composition of animals
The effect of amino acid feeds on egg production and egg weight
The effect of amino acid feeds on the composition of milk
Effect of amino acid feeds on animal hair quality
Composite amino acid use
Amino acid feed levels will affect the carcass composition of animals
The weight gain and daily deposition of protein in pigs will increase as the level of lysine in the feed increases. It does not decrease until the maximum need is met; and the amount of feed and carcass fat per kilogram of weight gain decreases with increasing lysine levels. Unbalanced amino acid composition of the diet can increase the amount of carcass fat deposit in broilers. Adding lysine methionine, aspartic acid and glutamic acid to the diet can reduce the visceral fat deposition in broilers.
The effect of amino acid feeds on egg production and egg weight
Amino acids have little effect on egg weight in early laying of laying hens, and have a greater impact on egg weight in the future. When the amino acid supply level is less than 5% of the maximum intake, the egg weight drops below 90% of the potential egg weight, and the egg production rate has dropped to 70% of the potential egg production rate. The amino acid that has the greatest effect on egg weight is methionine. In the early stage of egg laying (23-25 weeks old), adding methionine to low protein diet can significantly increase egg weight; in the late egg production (78-102 weeks old), the intake of methionine is reduced from 300mg/day to 270mg/day. Does not affect the egg production rate, can reduce the egg weight.
The effect of amino acid feeds on the composition of milk
Methionine and lysine are limiting amino acids for milk protein synthesis. Increasing the amount of amino acids that reach the small intestine of the cow, especially essential amino acids, increases the amount of milk protein. The method is to use feeds with low protein degradation rate, such as fish meal, feather meal, blood meal, meat meal, meat and bone meal, corn protein and formaldehyde-treated soybean meal. The second method is to add a protective amino acid such as a coating of methionine and a lysine or methionine hydroxyl analog.
Effect of amino acid feeds on animal hair quality
Supplementation of methionine and cystine increases wool break strength, elongation and length. Supplying a sufficient amount of amino acids, especially sulfur-containing amino acids, increases the density and diameter of rabbit hair and contributes to the growth of poultry feathers. All amino acid deficiency can cause abnormal feather growth. Among them, sulfur-containing amino acids and branched-chain amino acids are the most critical. The optimal feather growth requirement for methionine is greater than the optimal growth and optimal feed efficiency for methionine, and lysine deficiency. Causes feathers to fade and even whiten. Excessive leucine causes abnormal feather growth: the feather axis, feather twigs, plume branches can not be bent normally, the content of proline and isoleucine in the fragile feathers of the feathers is reduced, and the addition of proline and isoleucine can be improved. Feathers grow.
Composite amino acid use
1. After special spray drying, it is bulky and light, and its weight is only half of that of ordinary feed. It is especially suitable for the production of puffed aquatic feed, fish and shrimp, and sea fish open material.
2. Rich in cystine, tyrosine, serine can promote the growth of livestock and poultry fur, the skin of the pig is ruddy, the hair color is bright, the yellow chicken can increase the color of the hair color, the color of the chicken feet;
3. Flavoring and freshening, promote animal appetite, this product has high glutamic acid content, has the effect of regulating taste and promoting animal appetite. Aquatic feed can replace betaine to increase the palatability of feed;
The above is the effect of various amino acids on different livestock animals. Even the same amino acids have different effects on different animals, and different kinds of amino acids have the same effect on animals. So to make the most of the amino acid feed, you need to remember this information. Let the amino acid feed be fully utilized by you on your farm.
