为了探讨广西食用菌菌糠饲料化利用的可行性,试验对广西几种主要的食用菌菌糠进行常规营养分析,并结合兔、鸭、鹅、山羊、肉猪的营养需要配制平菇菌糠饲料进行对比饲养试验,观察不同动物的适应性,测定日增重、饲料转化率等指标.结果表明:菌糠含粗蛋白质9.80%~18.20%、粗纤维5.00% ~ 30.73%、粗脂肪1.1% ~3.5%、钙2.34% ~9.55%、总磷0.36% ~ 1.10%;添加18.3% ~20.0%菌糠养羊、兔、肉鸭及添加25.8%菌糠养鹩,饲料转化率高、经济效益好,平菇菌糠适合饲养草食动物,但不适合饲养瘦肉型猪;平菇菌糠再添加2%植物油可以改善肉鸭日增重、饲料转化率和经济效益.
近年来,随着我国动物疫病防控策略向疫病监测的转变,我国兽医工作方式的转变成为了必然的趋势.加强动物疫病监测是兽医保护动物的基本方式,同时,也是兽医工作转变的方向所在.基于此,主要分析了我国动物疫病监测的情况,并提出加强动物疫病监测以推进兽医工作方式转变的策略.
The effects of the temperature and relative humidity on six reproductive performance indicators of 686 Longlin goats from 2006 to 2007 were studied using the methods of correlation and curve regression analysis.The results showed that the extremely low or high temperature exerts an unfavorable effect on the reproductive competence of ewes and the high temperature and moisture have the greatest influence on them.
