不同营养水平下新疆褐牛增重效果研究
Effects of Different Nutrition Level on Xinjiang Brown Fattening
摘要
Abstract
60 Xinjiang brown cows with health disease-free,growth,age in normal were randomly divided into low cost of diet with high cost of diet group control group.The effects of different nutrition levels on fattening and cost of Xinjiang brown during different feeding periods were studied.The results showed that feeding amount and nutrition levels were lower than those of the control group in the whole period.In early stage,daily gain of Xinjiang browns in experimental group was 1.00 kg,lower than control by 0.14 kg,and there was significant difference（P 0.05）.In middle stage,daily gain of Xinjiang browns in experimental group was 0.63 kg,which in control group was 0.81 kg,and there was extremely significant difference（P0.01）.In final stage,daily gain of Xinjiang browns in experimental group was 0.68 kg,which in control group was 0.49 kg,and there was extremely significant difference（P0.01）.The average daily economic benefit of experimental group was higher than control group by 4.35 yuan per capital.关键词
