Effect of Different Feeding Levels on Production Performance and Digestive Tract Development of Lamb of First Filial Generation of Dorper sheep and Mongolian sheep
摘要
Abstract
In order to investigate the effect of different feeding levels on production performance and digestive tract development of lamb of first filial generation of Dorper Sheep and Mongolian Sheep (denominated as Dumeng hybrid F1), a total of 18 female lambs of Dumeng hybrid F/were chosen and randomly divided into 3 groups. The lambs in the 3 groups fed the same pelleted compound feed in different feeding levels of ad libitum feeding, 60%ad libitum feeding and 40%ad libitum feeding, respectively. The daily intake, weight gain, and indicators associated with slaughter performance and digestive tract development of the lambs in different groups were statically evaluated. The results showed that the slaughter weight, daily intake, total weight gain and daily weight gain were significantly increased with the improvement of feeding levels (P<0.05);The indicators of slaughter performance other than feed conversion ratio were significantly reduced with the decrease of feeding levels (P<0.05);The total weight of the four stomachs, large intestine weight and small intestine weight were significantly increased with the improvement of feeding levels (P<0.05). The production performance and digestive tract development of the lambs in ad libitum feeding group were superior.关键词
