Abstract:This study focused on the impact of different breeding modes (indoor feeding vs.outdoor feeding) on the efficiency of supernumerary ovulation in Alxa white cashmere goats.By strictly controlling non-breeding variables such as goat age (2-4 years),weight,health status,and reproductive stage,we ensure consistency and reliability of the experimental data.We use a randomized group assignment strategy to divide the experimental animals into an indoor feeding group (40 animals) and a outdoor feeding group (30 animals),and provide uniform nutrition,health monitoring,and standardized supernumerary ovulation procedures to minimize external factor interference.The results showed that the average FSH dose was suitable (150-160 IU),the average estrus time was stable (12 h after suppositing),and the average embryo recovery and the number of available embryos were significantly higher than those in the free-range group (12.56 vs 8.56 vs 12.56,respectively).(11.31 vs 7.81) and a low proportion of unusable embryos (10% vs 16%) (P<0.05).This study confirmed that by providing stable feeding conditions and refined management strategies,the house feeding environment significantly enhanced the superplatoon efficiency of Alxa white cashmere goats,showing obvious advantages over grazing mode.These research results not only laid the theoretical foundation for the sustainable development of cashmere goat farming industry,but also provided practical guidance to lead the industry in the future.They highlight the significant advantages of the house feeding mode in improving the efficiency of overdischarge,and inspire a new direction of fine feeding management,scientific nutrition regulation and reproductive technology innovation.These findings have inspired in-depth exploration and optimization of the breeding environment,nutritional formulations and breeding strategies to comprehensively improve the production performance of cashmere goats and promote the breeding industry towards an efficient,environmentally friendly and sustainable future.
