不同饲养管理条件对阿拉善白绒山羊超数排卵效果的影响

Impact of Different Feeding and Management Conditions on the Superovulation Effect of Alxa White Cashmere Goats

摘要:

本研究深入探讨了不同养殖模式(舍饲与放牧)对阿拉善白绒山羊超数排卵效率的差异化效应,通过严格调控非养殖变量如山羊年龄(2~4岁)、体重、健康状态及繁殖阶段,确保实验数据的高度一致性和可靠性。采用随机化分组策略,将实验动物分为舍饲组(40只)与放养组(30只),统一实施营养供给、健康监测及标准化超排操作,以最大限度削弱外部因素干扰。研究结果显示,舍饲组山羊展现出更为优越的超排性能,其平均FSH剂量适宜(150~160 IU),平均发情时间稳定(撤栓后12 h),且平均胚胎回收量与可用胚胎数显著高于放养组(分别为12.56枚/只vs 8.56枚/只,11.31枚/只vs 7.81枚/只),同时不可用胚胎比例较低(10% vs 16%)(P<0.05)。本研究确认,舍饲环境通过提供稳定的饲养条件和精细化的管理策略,显著增强了阿拉善白绒山羊的超排效率,相较于放牧模式展现出明显优势。这些研究成果不仅奠定了绒山羊养殖业可持续发展的理论基础,还提供了实践指导,引领行业未来。它们凸显了舍饲模式在提升超排效率上的显著优势,并启发了饲养管理精细化、营养调控科学化及繁殖技术创新的新方向。这些发现激发了对养殖环境、营养配方及繁殖策略的深入探索与优化,旨在全面提升绒山羊生产性能,推动养殖业迈向高效、环保、可持续的未来。

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.
