Abstract

The invention discloses a feed additive for reducing nitrogen excretion of ruminants and a preparation method thereof, relates to the field of feed, and is used to solve the problem of low absorption rate of nutrient substances in protein feed caused by restriction of digestion and absorption of nitrogen source substances by ruminants in the prior art , and feed additives have poor palatability and high cost. The feed additive for reducing the nitrogen excretion of ruminants, according to parts by weight, its raw material composition is 782-3128 parts of slow-release urea and 1564 parts of rumen-passing protective methionine; wherein, the slow-release urea includes: 322-1288 parts by weight Feed grade urea, 345-1380 parts of acrylic resin IV, 115-460 parts of pregelatinized starch; rumen-passing protective methionine includes: 204 parts of wall material, 1360 parts of DL-methionine core material. The feed additive for reducing the nitrogen excretion of ruminants in the invention can obviously reduce the nitrogen excretion of ruminants, increase the deposition of nitrogen in tissues, and at the same time improve the breeding environment and improve the breeding benefits.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed additive for reducing nitrogen excretion of ruminants and a preparation method thereof. Background technique [0002] Feed protein raw materials are an important source of animal nutritional requirements. At present, feed nutritionists mainly consider the animal's demand for protein and carbohydrate feed when optimizing feed formula, and try to design feed formula according to the degradation characteristics of the rumen. However, a large number of experiments have verified that when ruminants Sufficient degradable protein feed is added to the diet, but the degradation and utilization rate of nitrogen-containing substances in the digestive tract of ruminants is not coordinated with the degradation rate of energy carrier substances in the digestive tract, which will result in short-term energy carrier substances and nitrogen sources for rumen microorganisms. Degradation is uncoordinated...
