Composite additive for improving milk secretion milk protein and preparation method thereof

Technical Field

The invention relates to the technical field of biological feed, in particular to a compound additive for improving lactation cow milk protein and a preparation method thereof.

Background

Along with the development of global economy and the stimulation of increasing consumption demands of people, the yield of meat, eggs and milk in China is continuously innovative and high in recent years. But the industry fluctuation change of the livestock breeding industry also seriously influences the development of the dairy cow breeding industry, particularly the reduction of milk protein in milk caused by heat stress in summer of the scientific breeding of the lactating cows, improves the milk protein of the lactating cows as far as possible under the condition of ensuring the health of the cows, and achieves the purpose of improving the overall benefit of a dairy cow farm.

The change of cow milk protein is relatively difficult, and from scientific research in recent years, a large number of products come into the market and focus on utilization of dietary amino acid configuration such as rumen bypass methionine and lysine, but the problems of unobvious actual effect, high cost and the like exist. The invention adopts the integration of sustained release urea and nutrients such as plant extracts to improve the synthesis of rumen microbial protein and enhance the absorption of nutrient substances in intestinal tracts, thereby achieving the purpose of improving and increasing milk protein.

Disclosure of Invention

The invention aims to overcome the defects that the effect of increasing the milk protein product of the existing lactating cows is not obvious or the cost is overhigh. Provides a new product for improving the milk secretion protein of milk cow and a preparation method thereof.

The invention provides a composite additive for improving lactation cow milk protein and a preparation method thereof, aiming at the characteristics and the mechanism of the synthesis of the lactation cow milk protein. Thereby improving the overall economic benefit of the dairy farm.

Accordingly, the present invention relates to a complex additive for increasing the milk secretion of cow's milk protein, comprising a slow release urea and a plant extract mixture. Wherein the slow release urea is prepared from Shanghai Mugao Hi-Tech Co., Ltd, and has a molecular formula of CH₄ON₂(ii) a The plant extract mixture is mixture of plant extract chestnut and fenugreek, wherein the plant extract chestnut and the fenugreek are respectively from Italy and Canada, and the plant extract chestnut and the fenugreek in the plant extract mixture are prepared according to the weight ratio of 1: 2.

In the present invention, the slow release urea, plant extract mixture may be obtained commercially or extracted by a known method.

The content of the slow release urea in the composite additive for improving the milk secretion milk protein is preferably 50 to 90 percent by mass; the content of the plant extract mixture in the composite additive is preferably 10-50% by mass.

The inventor finds that the slow release urea can be synergistically acted with carbohydrates in daily ration of dairy cows to improve the synthesis of rumen microbial protein as much as possible; the plant extract mixture can effectively slow down intestinal peristalsis, improve the absorption and utilization rate of daily ration protein and rumen microbial protein in intestinal tracts, and achieve the purpose of improving milk protein. The optimal ratio of the slow release urea to the mixture of the plant extracts of the chestnut trees and the fenugreek is 5: 1-9: 1.

The above-described preferred conditions of the present invention may be arbitrarily combined to produce preferred examples.

In the invention, the compound additive for improving the lactation cow milk protein can only adopt the preparation method used by the invention, and the action effect of the product is ineffective or greatly reduced if not:

1) firstly, mixing plant extracts of chestnut trees and fenugreek to obtain a first mixture, and mixing the obtained first mixture with slow-release urea to obtain a second mixture;

2) and packaging and stacking the second mixture to obtain the compound additive for improving the lactation cow milk protein.

The preparation method comprises mixing plant extract of semen Castaneae and semen Trigonellae, wherein the plant extract of semen Castaneae and semen Trigonellae is mixed uniformly; secondly, the obtained first mixture is mixed with the slow release urea. The sequence of the manufacturing method ensures that the quality of the finished product and the functions of the product are avoided.

The preferred main nutritional indicators of the present invention are shown in table 1.

The components in the embodiment 1 are uniformly mixed according to the preparation method steps of the invention, and the composite additive for improving the milk secretion protein of the lactating cow is obtained, wherein the weight percentages are above.

The compound additive for improving the milk secretion protein of the milk secretion in the embodiment 1 is used for testing in a certain dairy farm in Shanxi Weinan (the test is 60 days, 7 months and 8 months), 1 milk secretion dairy house is selected, 800 milk secretion days are selected, the milk secretion days are about 120 days, the number of births is 2, the two milk secretion feeds are randomly divided into 2 groups, and each group is 500, and I, II two milk secretion feeds are correspondingly fed. The average fetal times, varieties and fetal times of each group have no difference. Standardizing the feeding procedure of the lactating cows. Production of test materials: the raw dairy farm feed is produced according to the feed formula of the existing program; the test group I was supplemented with 160 g/head of the original feed per day and the test group II was supplemented with 160 g/head of the product of example 1 per day. The addition was done by a special person (3 daily feeds, 40 grams each) with a special custom made container. The original feed or the milk products of the dairy cows are evenly mixed in the feed of the original dairy cow farm each time for adding and feeding. Daily feed intake, milk protein, etc. were recorded.

Table 2 effect of example 1 on milk ingredients

	I (not added)	II (addition of the product of example 1)
			DM feed intake/head/day Kg	23.5	23.7
Milk protein%	3.2％	3.4％
			The percentage of butter fat%	3.9％	4.0％

The results show that the milk protein of the test group is averagely improved by 0.2 percent compared with the control group, and the milk fat rate is improved by 0.1 percent. The test shows that the invention is effective in improving the lactation cow milk protein, and the result is shown in table 2.

Example 2

slowly released urea 50 percent and plant extraction mixture 50 percent.

The test was carried out in a certain dairy farm in the Shanghai using the composite additive for increasing lactating cow milk proteins of example 2, and the test cow selection, test procedure and feeding were the same as in example 1. The results are shown in Table 3.
