Abstract

The invention discloses a fattening sheep feed additive and a preparation method thereof. The feed additive comprises 60% of plant source dry powder, 20% of enzyme substance and 20% of microbial agent, wherein the plant source dry powder comprises 30% of suaeda salsa whole plant dry powder, 10% of dandelion whole plant dry powder, 10% of honeysuckle vine dry powder, 5% of jerusalem artichoke stem block dry powder and 5% of purslane stem leaf dry powder. The feed additive mainly has the effects of solving rumen inflammation and food retention of fattening sheep, improving food consumption and daily gain and realizing aureomycin substitution.

Description

technical field [0001] The invention belongs to the field of animal feed, in particular to a feed additive for fattening sheep and a preparation method thereof. Background technique [0002] The appetite of house-feeding sheep is generally poor. During the feeding process, it is usually necessary to select and prepare feed with good palatability, diversification, and easy digestion to ensure comprehensive and balanced nutrition, so as to meet the needs of the sheep for growth, development, reproduction, and weight gain. demand. Since sheep are ruminants, the roughage in the general ration should account for 2 / 3 of the total ration, and the concentrated feed can account for 1 / 3 of the total ration. However, at present, in order to quickly fatten and increase income, farmers mainly adopt the feeding method of mixing concentrate and supplemented by coarse feed. 1-2% of. Due to the feeding of a large amount of concentrate, it causes rumen inflammation and food accumulation, w...
