preparation example Construction
[0028] 1. The preparation method of coated γ-aminobutyric acid:
[0029] With solid palm oil (also called solid palm oil) as the coating material, γ-aminobutyric acid and solid palm oil are mixed according to the weight ratio of 1:1, and the coating machine is used under the working pressure of 11 kPa It is obtained by wrapping.
Embodiment 1
[0031] Embodiment 1, a kind of rumen-passed GABA milk cow concentrate is made up of base material, coated gamma-aminobutyric acid and various additives; base material is made up of the raw material of following dry matter weight part:
[0032] 53 parts of corn, 11 parts of soybean meal, 7 parts of cottonseed cake, 5 parts of cottonseed meal, 8 parts of sesame meal, 8 parts of wheat bran, 2 parts of calcium hydrogen phosphate, 2 parts of light calcium carbonate, 1 part of calcium bicarbonate, 1 part of table salt and 1 part baking soda;
[0033] Add 80mg of coated γ-aminobutyric acid, vitamin A 10000IU, vitamin D 2000IU, vitamin E 12.5IU, zinc 140mg, selenium 1mg, iodine 1.8mg, iron 30mg, cobalt 0.4mg, manganese 30mg and Copper 30mg.
[0034] The preparation steps are as follows: simply mix base material, coated gamma-aminobutyric acid and various additives according to the above dosage ratio.
Embodiment 2
[0035] Embodiment 2, a kind of rumen-passed GABA dairy cow concentrate, the coating gamma-aminobutyric acid that adds in every kg base material dry matter is changed into 160mg from 80mg, all the other are the same as embodiment 1.

Abstract
The invention discloses a rumen bypass GABA cow concentrate which comprises a base material and a coated gamma-aminobutyric acid; the base material comprises the following raw materials on a dry matter weight basis: 52-54 parts of corns, 10-12 parts of soybean meal, 6-8 parts of cottonseed cake, 4-6 parts of cottonseed meal, 7-9 parts of sesame meal, 7-9 parts of wheat bran, 1.5-2.5 parts of calcium hydrogen phosphate, 1.5-2.5 parts of light calcium carbonate, 0.5-1.5 parts of calcium bicarbonate, 0.5-1.5 parts of edible salt, and 0.5-1.5 parts of sodium bicarbonate; the weight ratio of the coated gamma-aminobutyric acid and the base material dry matter is 75-245 mg / kg. The invention can increase the feed intake and reproduction performance of cows at a lactation peak period.
Description
technical field [0001] The invention relates to the field of feed for dairy cows, in particular to a dairy cow feed prepared by using rumen-passed GABA, which can be used for Chinese Holstein cows in the peak lactation period. Background technique [0002] γ-Aminobutyric acid (GABA) is a non-protein amino acid that plays a calming role in animals. It is not only widely distributed in the central nervous system, but also exists in the cells of peripheral nerves and non-nervous tissues. It plays a role in non-nervous tissues. The function of hormones or nutritional factors plays an important role in regulating the normal physiological functions of animals. As a functional amino acid feed additive, GABA has many functions such as improving animal production performance and product quality: 1) GABA can cause animals to eat food by inhibiting the activity of the satiety center, adding GABA to the basic diet of fattening pigs , can significantly increase the feed intake of pigs, ...
