放牧绵羊冬春季节牧草采食量和消化率的研究
Study on Forage Intake and Digestibility of Grazing Sheep in Winter and Spring
摘要
Abstract
In order to study nutrition status of grazing sheep in winter and spring,the experiments using n-alkanes as markers to estimate the forage intake and digestibility of grazing sheep were carried out in zhaosu Results showed that the forage intake of growing ewes in winter and spring was 661.68,856.92 g/ d respectively;the herbage intake of mature ewes in winter and spring was 876.97,1021.83 g/d respectively.The forage intake of sheep in spring was higher than that in winter,with a significant difference(P<0.05).The dry matter digestibility of growing ewes in winter and spring was 39.05% 、45.85% respectively,which of mature ewes in winter and spring was 45.76 % 、50.50% respectively.The dry matter digestibility of sheep in spring was higher than that in winter,with a significant difference(P<0.05).关键词
