Feed additive for small-tailed Han sheep, preparation process and application method thereof

Abstract

The invention provides a feed additive for Small-tailed Han sheep, a preparation process and a use method thereof. The feed additive includes the following raw materials in mass percentages: 15-20% of lemongrass extract, 12-14% of Cordyceps flower extract, Houttuynia cordata extract Selenium-enriched yeast powder 20-25%, broken wall selenium-enriched yeast powder 5-30%, broken bee pollen 5-10%, β-sitosterol 1-2%, rumenin 0.1-0.2%, urea phosphate 10-15%, sulfuric acid Copper calcium 0.1‑0.3%, chromium picolinate 0.4‑0.5%, glycine complexed iron 0.4‑1%, rumen-passed methionine 3‑6%, rumen lysine 3‑6%. The added amount of the feed additive in the small-tailed Han sheep concentrated feed and roughage is 300-800g / t and 200-500g / t respectively. The feed additive of the present invention can stimulate the small-tailed Han sheep to eat food, promote rumination, invigorate the stomach, eliminate gas, digest and absorb, effectively reduce the incidence of rumen flatulence, increase the feed remuneration rate, improve the body immunity of the small-tailed Han sheep, and effectively reduce the incidence of sheep disease incidence.

Description

technical field [0001] The invention belongs to the technical field of animal feed additives, in particular to a feed additive for small-tailed Han sheep, a preparation process and a use method thereof. Background technique [0002] Small-tailed Han sheep is an animal under the Bovid family and Sheep subfamily. It is a well-known sheep breed with both meat and fur in my country and even in the world. It has the advantages of good fur, stable heredity and strong adaptability. At the age of 4 months, it can be fattened for slaughter, and the annual slaughter rate is over 400%; at the age of 6 months, it can be bred and conceived, with 2 litters per year, 2-6 litters, sometimes as high as 8; the average lambing rate per litter is over 266% . [0003] Small-tailed Han sheep are ruminants. During the breeding process, the concentrate with soybean meal and fish meal as the main components should not be fed too much, otherwise it will lead to abnormal fermentation of rumen microor...

AI Technical Summary

Problems solved by technology

[0003] Small-tailed Han sheep are ruminants. During the breeding process, the concentrate with soybean meal and fish meal as the main components should not be fed excessively, otherwise it will cause abnormal fermentation of rumen microorganisms, and a large amount of gas will be produced rapidly, which will expand rapidly in the rumen of Small-tailed Han sheep, causing Symptoms of rumen flatulence, and further cause symptoms such as cessation of rumination, difficulty in breathing, difficulty in digestion, and decreased feed intake; During the process, synthetic antibiotics, synthetic hormones, and sulfonamide chemical additives are generally added to the feed. Long-term use will destroy the immune regulation system of Small-tailed Han sheep, produce drug resistance, and cause drug residues.
