摘要
作者结合饲养试验与呼吸测热,对275.7～478.7公斤体重的“西门塔尔×广东湛江黄牛”杂种肉牛生长育肥的能量代谢规律进行了研究,总结出其增重能量需要计算公式,为修定和增补我国《肉牛的饲养标准(试行)》提供了试验数据。
Feeding and Energy Balance Trials by Closed Circuit Mask Method with Growing and Fattening Cattle of Simmental × Guangdong ZhanJiang Native Breed Showed that the Energy Retention is RE(Kcal) = (1088.97 + 7.5168W) × Daily Gain, n = 6, r = 0.6901, P<0.05. The mean Differences Between the Feeding and Energy Balance Trials for Eesti-mating the Energy Retention was 0.87%.
