Problems solved by technology

The feed and additive products prepared according to the above research ideas greatly increase the burden on the rumen of cattle, and are likely to cause common diseases such as gastric distension. These feed and additive products also have the disadvantages of slow onset of action and single effect. At the same time, these products The amount of phosphorus added in is too high, which increases the discharge of organic phosphorus, which in turn increases the pollution to the environment

Embodiment 7

[0045] Example 7 Animal experiment of compound amino acid additive for cattle feed

[0046] Experiment 1: Beef cattle experiment

[0047] The compound amino acid additives M1-M6 for cattle feed provided by Examples 1-6 are added to the common silage cattle feed respectively, and the mixed cattle feed is marked as SM1-SM6 one by one, and the addition of feed additives M1-M6 The amount is 0.5% of the total weight of the feed.

[0048]Select 140 beef cattle with good and consistent body condition, weight, and health status, and randomly divide them into seven groups, namely RM1-RM7 groups, 20 cattle in each group, among which RM1-RM6 groups are fed one-to-one with cattle feed SM1-SM6, RM7 The group was fed with common silage cattle feed supplemented with 0.5% of the total feed weight of a certain cattle feed additive in the market as the control group, and the seven groups were fed with ad libitum feeding in the morning, noon and evening respectively, and fed for 100 days, and r...

Abstract

The invention belongs to the technical field of feed additives, and discloses a compound amino acid additive for cattle feed as well as a preparation method and application thereof, and the additive is prepared by uniformly mixing rumen protected lysine, rumen protected methionine, phytase, energy protease, neutral protease, cellulase, compound vitamins, compound minerals and other raw materials. The obtained compound amino acid additive for the cattle feed is used in cooperation with feed. According to the invention, by adding the raw materials with a reasonable ratio and utilizing the interaction among the components, the cattle rumen morbidity is reduced; various rumen bypass amino acids are added to improve the return rate of the feed; by adding various enzymes, the acid-base stability of the rumen environment of the cattle is improved, the morbidity of the rumen is reduced, the digestibility of the raw materials is improved, the physique and production performance of the cattle are enhanced, and economy and environmental protection are achieved. The additive disclosed by the invention is suitable for being added into feed to feed cattle.

Description

technical field [0001] The invention belongs to the technical field of feed additives and relates to an additive for cattle feed and its preparation method and application, in particular to a compound amino acid additive for cattle feed and its preparation method and application. Background technique [0002] The bovine rumen is the largest among the four stomachs, with a volume of about 300-400L, accounting for 80% of the total stomach. As the main digestion site for roughage, 70-85% of dry matter and about 50% of crude fiber are processed in the rumen. Digestion and rumen health are critical to the metabolic level and subsequent performance of cattle. At the same time, the complex microbial environment in the rumen of cattle will degrade some amino acids, causing insufficient amino acids to reach the small intestine, thereby reducing the feed return rate. Therefore, paying attention to the health of the rumen and improving the rate of return on cattle feed is a hot spot i...
