Abstract:In order to further study the promotion and application effect of early weaning technology of lambs in the production of meat sheep in Tianzhu pastoral area,the project team conducted an experiment on early weaning and fattening of Tianhua meat sheep lambs in Tianzhu pastoral area.Eighty Tianhua lambs with the same birth date and origin were selected for the experiment.There was no significant difference in birth weight and body weight among the subjects at 20 day old (P>0.05).They were randomly divided into experimental groups S1,S2,S3,and control group D1.The experimental group was weaned and fattened at 20 day old,35 day old,and 50 day old,respectively,while the control group was fed normally.The results showed that the average daily weight gain of the experimental group during the fattening period was 217.5,198.1 and 191.1 g,respectively.The average daily weight gain of the control group was 130 g at 120 d.The average daily weight gain of the experimental group was higher than that of the control group,and the difference was significant (P<0.05).The weight gain statistics during the entire feeding period of lambs showed that the weight gain and average daily weight gain of the experimental group were 32.4 kg,231.4 g,33.0 kg,235.7 g,and 30.4 kg,217.1 g,respectively.There was no significant difference between the groups (P>0.05),while the control group had 21.6 kg and 154.3 g,which were lower than the experimental group.The difference in weight gain between the experimental group and the experimental group was significant (P<0.05).The experiment shows that promoting early weaning and fattening technology for lambs in the production of meat sheep in Tianzhu pastoral area is feasible and can achieve good daily weight gain production benefits.
