临夏地区藏羊异地育肥日粮配方试验研究

本试验对引进的藏羊进行异地育肥和经济效益研究,以期筛选质优价廉的日粮配方,切实提高藏羊生产性能,增加育肥效益。结果表明:试验Ⅰ组的公、母羊日增重分别比对照组提高了32.29%、29.02%,试验Ⅱ组的公、母羊日增重分别比对照组提高了44.37%、31.44%,试验Ⅰ组和Ⅱ组的料重比均比对照组有所降低,两个试验组增重效果均显著高于对照组(P0.05),但试验Ⅰ和Ⅱ组之间差异不显著(P0.05)。试验Ⅰ组公、母羊比对照组每只分别多收入66.77元、48.95元,比试验Ⅱ组多收入9.24元、20.18元。虽然试验Ⅱ组增重效果优于Ⅰ组,但其饲料成本较高,经济效益低于Ⅰ组。因此,用搭配科学合理的异地育肥配方1日粮饲喂藏羊,可获得良好的增重效果和经济效益。

Study on Diet Formulation of Allopatry Fattening of Tibetan Sheep in Linxia

Allopatry fattening and economic benefit were studied with Tibetan sheep and screening diet formulation of high quality and low price to improve the production of Tibetan sheep and to increase economic benefit. The results showed that compared to control group, the daily weight gain of the experimental group I improved 32.29% （male） and 29.02% （female）, the daily weight gain of experimental group Ⅱ improved 44.37% （male） and 31.44%（female）, respectively. The feed/gain ratio of the test I and Ⅱ group decreased. There was no significant difference between test experimental group I and group Ⅱ （P 〈0.05）. The income of experimental groupⅠ was 66.77 Yuan （male） and 48.95 Yuan （female）, the income of the experimen- tal group Ⅱ was 9.24 Yuan （male） and 20.18 Yuan （female）. The weight gain effects of experimental group Ⅱ was better than the group Ⅰ, however, feed costs were higher Therefore, the I diet formulation of allopatry fattening of scientific and reasonable to feed Tibetan sheep could get higher weight gain effect and economic benefits.
