Embodiment 1

[0019] The prepared palm oil-coated rumen-passed lysine granules are added to the feed of dairy cows for feeding, and the addition amount is 40 grams / head / day;

[0020] The dairy cow feed used therein can be conventional dairy cow feed formula, and its a kind of specific composition is as follows: oat grass 1kg, alfalfa 4 kg, cottonseed 2 kg, concentrate supplementary material 9 kg, brewer's grains 6 kg, silage 18 kg, embodiment Prepared palm oil-coated rumen-passed lysine granules 40 g

[0021] For the use effect, the results are shown in Table 1:

[0022] Table 1: Effects on lactation performance of high producing cows

[0023] index

[0024] The result shows: the use effect of the present invention is better than the rumen-passing lysine sold on the market

Abstract

The invention aims to provide palm oil coated rumen-protected lysine feed for the lactation period of dairy cows. The feed comprises components in percentage by mass as follows: 10% of lecithin, 20% of palm oil and 70% of lysine. The palm oil coated rumen-protected lysine is used for producing feed for the lactation period of dairy cows. The rumen protection efficiency of the palm oil coated rumen-protected lysine can reach 98%, the particle size is smaller than 0.80 mm, and the dissolution rate of lysine in small intestines can reach 98%. Fat considers comprehensive demands of dairy cows forvarious fatty acids, and the problems of low milk protein content and metabolic disorder and the like caused by lack of lysine in the lactation period of dairy cows.

Description

technical field [0001] The invention belongs to the technical field of dairy cow feed components, and in particular relates to palm oil-coated rumen-passed lysine used in the lactation period of dairy cows. Background technique [0002] In the nutritional research of monogastric animals and the evaluation of the nutritional value of feed protein, the concept of limiting amino acids has been given sufficient attention and application. As far as ruminants are concerned, when the production performance is improved, the amino acid transport, absorption and utilization in the small intestine and the production of microbial protein are limited, resulting in an increase in the amino acid requirement, showing the restrictive effect of certain amino acids. Therefore, the role of limiting amino acids also exists in ruminant nutrition. Studies agree that lysine (Lys) and methionine (Met) are the first and second LAAs in ruminants. [0003] Direct supplementation of lysine in ruminant...
