Abstract

The invention discloses a process for applying non-ionic surfactant (NIS) in breeding ruminants, which comprises drying corn straws, rice straws and wheat straws after harvesting seeds, and pulverizing; adding APG, Span 85 and Tween-80 into pulverized corn straws, rice straws and wheat straws, respectively; conducting in vitro fermentation, and measuring gas production (GP) and in vitro dry matter digestibility (IVDMD); and determining the types and addition levels of NIS in different types of coarse feeds in accordance with the in vitro fermentation properties. The inventive process is simple and easy to operate, effectively improves the promotion of rumen microorganisms in ruminants on fermentation of straw coarse fodders, and improves the dry matter and organic matter digestibility in rumen, so as to improve the utilization ratio of coarse fodders.

Description

technical field [0001] The invention belongs to the field of feed utilization technology, and more specifically relates to an application technology of NIS for improving the utilization efficiency of straw feed. Background technique [0002] Straw is the most abundant by-product of crops. It has the characteristics of large volume and high crude fiber content. It is suitable for feeding ruminant livestock and can increase the milk fat rate of lactating animals. Therefore, making full use of crop straw on ruminants can not only improve breeding efficiency, but also reduce environmental pollution. However, due to the thick and hard stems of straw and the long residence time in the digestive tract, the palatability and feed intake of livestock are affected; at the same time, the nitrogen content of straw is low, the content of crude fiber is high, and the combination of cellulose and lignin is firm, making it difficult for animals to digest use. Generally speaking, the digest...
