In view of the current situation of the imperfect goat breeding system,the low rate of self-determination of goat breeds,and the weak technical strength of breeding enterprises,a goat digital breeding management system with genetic evaluation and seed selection as the core business functions was designed and demonstrated in goat breeding enterprises in Yunnan Province.Based on the statistical analysis function of the system,the changes in the number of breeding goats,reproductive performance,growth performance,and comprehensive selection index of Yunshang black goat and Boer goat core populations were analyzed.The results showed that the application of the goat digital breeding management system improved the production management and breeding management effectiveness of breeding enterprises.Compared with 2019,the core population of Yunshang black goat increased by more than 3600 in 2022,and the core population of Boer goat increased by more than 2200 in 2022.The birth litter weight of Yunshang black goat increased from 6.21 kg to 6.71 kg,and the number of lambs per litter increased from 2.10 to 2.12(Lixin Goat Industry Co.,Ltd.).Compared with 2019,the 12-month body weight of Yunshang black goat increased from 36.19 kg to 38.97 kg in 2021,and the backfat thickness decreased from 2.78 cm to 2.67 cm.The comprehensive selection index of Yunshang black goat rams increased by 0.71%,and the comprehensive selection index of Boer goat rams increased by 1.38%.The comprehensive selection index of Yunshang black goat ewes increased by 0.80%,and the comprehensive selection index of Boer goat ewes increased by 1.17%.The system has been running smoothly in the demonstration application field,with perfect functions and simple operation,providing technical support for enterprises to continuously select and breed excellent varieties.
