Effects of pen-fed on farmers’ income of sheep production in cold season in semi agricultural and semi pastoral area in Wushaoling Mountain of Qing-hai Tibetan plateau
摘要
Abstract
In order to study the effects of sheep management patterns on farmers’ income,ten households were selected in semi agricultural and semi pastoral area in Wuahaoling Mountain.In each household there were at least 30 pregnant ewes with 3-years-old and the body weight of these ewes were similar.Sheep from five households were fed in pen in cold season,which were classified in test group.At the same time,sheep from the other five household grazed in day and got supplementary feeding in the evening,which were classified in the control group.The results showed that the ewes’ weights of two groups decreased by 1.17 and 2.71 kg after the lambs born one month,respectively.Then the body weights of test group started to recover and they gained 0.68 kg on average at the end of three months after the lambs were born.However,for the control group,they continued to lose body weight.At the end of three months after the lambs born,these ewes lost their weight by 5.96 kg on average,which accounted for 13.91% of the original weight.The born weight of lambs between two groups had no significant difference,but average daily gain of the test group was significantly higher than that of the control group,and the lambs’ body weights of test group in two months and at the sale time were significant higher than the control group（P〈0.05）.Farmers’ income of the test group was 20.27 Yuan·ewe-1 higher than that of the control group.关键词
