棉粕日粮对艾维茵肉仔鸡的影响

Study on the Growing Law of Broilers Feeded Maize-Soybean-Cottonseed-Meal Diet

采用“玉米—豆粕—棉粕”型日粮饲喂艾维茵肉仔鸡，测各周龄体重。并建立其回归方程、进行显著性检验。分析周增重与日增重、周增重与饲养成本间的多元回归关系与相关性。肉仔鸡饲养到第５周龄时，日增重最高为６０．９７ｇ，饲养到第６～７周龄时饲养成本最低为８．

Maize-soybean-cotton-meal diet was adopted to feed broilers,their growth index at various growing stages and body weights in different week-age tested,the regression equation founded,and test of significance carried out.The results showed that body weight at different week-age presented significant difference in various degree,and poly-regression correlation and relativity between week-age and daily gain,week-age and feed cost were further analysed and founded that the daily gain was at the highest(60.97) at the week five;while the feeding cost was at the lowest($8.663) at the 6th-7th week.
