摘要
试验山羊分为3组。预试期7d,正试期60d。第1组10只大白山羊,舍饲全价颗粒饲料,平均每天每只羊采食0.79千克。第2组10只波尔山羊与大白山羊杂交一代,舍饲条件与1组完全相同,平均每天每只羊采食0.91千克全价颗粒饲料。第3组10只大白山羊,每日放牧6~8h(主要牧草品种为水草),平均每天每只羊补饲混合精料175g。第1组增重比第3组提高118.5%(P<0.01)。第2组料肉比比第1组低29.24%(P<0.01)。第2组只月收入是第1组的4.02倍,第1组是第3组的18.5倍(P<0.01)。试验结果证明,山羊完全可以舍饲,舍饲山羊的经济效益大大超过放牧山羊,同时品种改良可以大大提高饲料利用率。
Experimental goats were allotted to one of 3 groups.A7-d pretrial period by a 60-d trial regular period. Group 1,consisting of 10 Dabai goats,was house-fed 0.79kg of complete pellet feeds daily per goat.Group 2, consisting of 10 F1 offspring of Boer and Dabai goats,was house-fed 0.91kg of complete pellet feeds daily per goat in the same way as group 1.Group 3,consisting of 10 Dabai goats, grazed mainly on water plants 6~8 h daily, and was supplemented with 175g of mixed concentrate per goat daily. Group 1 gained 118.5% more than group 3(P<0.01).Group 2 had a mutton to feed ratio 29.24% lower than group 1 (P<0.01). The results indicated the feasibility of goat house feeding, a greater economic return of house- fed goats over grazing goats,and the important role of breed improvement in improving feed efficiency.
