Abstract

The invention discloses application of lycium barbarum polysaccharide in preparing a feed additive for reducing a ruminant rumen gas production rate. The fact that the lycium barbarum polysaccharide can be applied in preparing the feed additive for reducing the ruminant rumen gas production rate is discovered for the first time; 0.1 to 0.5 percent of lycium barbarum polysaccharide is added in a feed for ruminants, so that the output of greenhouse gases such as methane and carbon dioxide in rumens can be remarkably reduced, and the rumens are prevented from producing flatus; meanwhile, the degradation rates of dried matters and crude protein in the feed for the ruminants can be also improved, and the utilization rate of the feed is effectively improved.

Description

technical field [0001] The invention relates to the use of a wolfberry polysaccharide in the preparation of a feed additive for reducing rumen gas production in ruminants. Background technique [0002] Rumination refers to the process in which ruminants such as cattle and sheep return the semi-digested food in the stomach to the mouth for chewing again after a period of eating. Ruminants are animals with rumination phenomenon, usually some herbivores, because the plant fiber in roughage is relatively difficult to digest, so it is necessary to promote the digestion of roughage by rumination. The stomach of most ruminants consists of four parts: rumen, reticulum, omasum, and abomasum. Among them, the rumen is the first stomach of ruminants such as cattle and sheep. The feed eaten by ruminants first enters the rumen. In the rumen, the feed goes through the processes of rumen fluid moistening, cutting, physical mixing and rumen microbial fermentation. Molecules are degraded in...
