The invention discloses a feed additive which uses capsaicin to increase the feed intake of mutton sheep, thereby increasing the weight gain and shortening the fattening time. Mutton sheep feed, first to meet their life maintenance needs, and then can be used for growth. When the intake of nutrients is insufficient, the proportion of nutrients used for growing parts to total nutrients intake decreases significantly. Increasing the feed intake of mutton sheep can increase the weight gain and shorten the fattening time. The invention adds capsaicin or capsaicin-containing substances to the feed of mutton sheep to make the capsaicin content in the diet of mutton sheep reach 0.0001 1%, increase the feed intake of mutton sheep by more than 15%, increase the daily gain by 20%, shorten the fattening time by 10 days, and improve the immunity and cold resistance of mutton sheep, improve the quality of mutton, especially suitable for the fattening of mutton sheep in late autumn, winter and early spring in the north. Capsaicin or capsaicin-containing substances can be used as feed additives alone, or added to premix, concentrate, full-mixed diet or full-price formula feed.

一种提高肉羊采食量和增重的饲料添加剂
本专利技术涉及一种饲料添加剂,具体涉及一种利用辣椒素提高肉羊采食量和增重的饲料添加剂。
技术介绍
我国羊存栏量3亿只以上,是农民重要的收入来源。养羊业正面临着转型升级,养羊从生产羊毛为主正转向生产羊肉为主,从放牧或放牧舍饲兼顾转向到舍饲。如何提高舍饲条件下肉羊日增重是一个重要的研究课题。健康肉羊日增重的提高取决于合理的日粮配方供给平衡的营养物质,还取决于肉羊对日粮采食量。人们往往重视日粮配方,而忽视采食量。肉羊摄入的营养物质首先用于维持生命活动的需要,维持需要占总摄入营养物质的40%以上,多余部分才用于生长增重。采食量不足,有时肉羊连维持需要也满足不了,体重出现负增长。只有采食量充足,才有营养用于生长。采食量越高,用于生长的营养物质占总摄入营养物质的比例越高,生长越快。肉羊通过嗅觉来寻找食物,良好的饲料气味刺激肉羊嗅觉,提高肉羊采食量。生产上有应用诱食剂,提高舍饲条件下肉羊采食量,但这类诱食剂大多人工合成,消费者有疑虑。花椒、桂皮、姜、小茴香、艾叶等增香剂,也可调节肉羊的食欲,增加采食,但价格较为昂贵,投入产出比低。添加由天然 ...
