Fine hair goat daily ration and its using method

Abstract

The present invention relates to a kind of daily feed for barn feeding and half barn feeding down goats. Sulfur content in the daily feed is 0.18~0.23%, the nitrogen sulfur ratio is 7-9: 1. Using method: during the vigorous cashmere growth period, Sulfur content in the daily feed is 0.20~0.23%, the nitrogen sulfur ratio is 7-8: 1, during the slow cashmere growth period, Sulfur content in the daily feed is 0.18~0.20%, the nitrogen sulfur ratio is 8-9: 1.

Description

technical field [0001] The invention relates to the technical field of nutritional control of cashmere goats housed and half housed fed, in particular to a cashmere goat ration and a use method thereof. Background technique [0002] Cashmere is the main product of cashmere goats. Its fibers are thin and soft, light and warm, and cannot be replaced by any other fibers. It is known as the "jewel of fibers" and has extremely high economic value. my country is the world's largest breeding country for cashmere goats, but the main breeding mode is natural stocking. With people's emphasis on ecological environment protection, it is inevitable to raise cashmere goats in semi-sheds. The main component of cashmere fiber is keratin, and the sulfur content in keratin is relatively high. Most of the sulfur exists in the form of cystine, and a small part exists in the form of cysteine, of which cystine accounts for 11-13% of all amino acids. , and the rations with straw as the main rough...

Problems solved by technology

[0004] After more than ten years of research on cashmere goats by China Agricultural University, it was found that the yield and quality of cashmere have a great relationship with the sulfur content of the diet and the ratio of nitrogen and sulfur. The NRC sheep feeding standard is not suitable for the production of cashmere goats. At the same time, the Ratio of higher feed costs
