Abstract:

To study the adaptability of the introduced variety of goats in South China,the reproductive performance and disease characteristics of the Chuanzhong Black goat under barn feeding condition were statistically analyzed,which would provide data for the feasibility analysis of feeding Chuanzhong Black goat in South China.The data related to the performances of the reproduction,growth and disease of the goats were collected from 2014 to 2017,and Excel and SPSS software were used to analyze the experimental data.The results showed that the primiparous lambing rate of Chuanzhong Black goat was 181%,and the lambing rate of the pluriparous goats was 200%;The alive lambs rate and weaning survival rate were 87.2% and 83.8%,respectively;The average birth weight of male and female lambs was 2.85 and 2.75 kg,respectively;The average weaning weight was 10.15 and 9.64 kg,respectively;The parity per year was approximately 1.5.Under the barn feeding condition in South China,the reproductive performance of Chuanzhong Black goat decreased slightly compared with the animals in the original region;However,with the increase of living time and improvement of feeding condition,the reproductive of Chuanzhong Black goat gradually recovered.In the case of barn feeding environment,goats were prone to pneumonia,and were easy to abort due to illness in the late pregnancy;The mortality of lambs increased as the number of lambs born increases.In conclusion,the Chuanzhong Black goat introduced from other provinces exhibited certain adaptability problems in the short-term,but under the suitable feeding and advanced management environment,they could maintain excellent reproductive performance and the characteristic of disease resistance.Therefore,Chuanzhong Black goat were feasible to be raised under barn feeding environment in South China.
