Fattening Performance of Different Lamb Hybrid Combinations in Sunan Pastoral Area of Gansu Province
摘要
Abstract
In order to discuss the optimization model of lamb production under grazing conditions in Hexi Sunan pastoral area of Gansu province with introduced Black Suffolk,Texel,Polled Dorset as male parents and Gansu Alpine Merino as female parent,a comparative study on their hybrid effects was carried out under the similar management condition.The results indicated that the weaning weight,average daily gain,carcass weight,dressed meat weight,and dressing-out percentage of the three hybrid combinations F1 of Black Suffolk×Gansu Alpine Merino,Texel × Gansu Alpine Merino and Polled Dorset×Gansu Alpine Merino were higher than those of Gansu Alpine Merino (P＜0.05 or P＜0.01);the weaning weight,average daily gain,carcass weight,deressed meat weight of the Texel×Gansu Merino F1 were higher than those of the other two hybrids and the Gansu Alpine Merino lambs.According to the growth rate,weaning weight and dressing percentage,Texel(♂)×Gansu Alpine Merino (♀) was the best hybrid combination for the production of fat lamb under the natural grazing condition of Huangcheng grassland in Sunan county,Gansu province.关键词
