摘要
研究结果表明,藏羊“春乏期”从冬季11月中至翌年春季4月初,约135天左右。其体重与气温呈负相关,且差异极显著(r=-0.7563)。补饲最佳时期为12月15日(半月均温-10.2℃)至4月2日(半月均温2.8℃),共计110天。四种不同补饲措施中,以每只羊日补饲草粉0.25kg、青干草0.5kg、混合料0.25kg 均有极显著效果(p<0.01)。
The result showed that the duration of“spring weakness”of Tibetan sheep is about 135 days from November to April of the next year.Its body weight and air teml'erature have a negative relation (r= 0.76).And the difference is extremely significance(r=-0.7563).The finest supplemental feeding period is from 12,December to 2,April,accumulate day 110.In the four different supplemental feeding methods,one sheep was supplied 0.25kg hay,0.5kg green hay and 0.25kg mixed fodder per day has a obvious effect.
