Heat stress caused by high temperatures in summer is a key challenge restricting the profitability of dairy farming. It not only reduces milk yield but also significantly impairs the reproductive performance of dairy cows. This paper systematically reviewed the mechanisms by which heat stress damages the physiological functions, endocrine homeostasis, and reproductive performance of dairy cows, with a focus on analyzing the negative effects of high-temperature enviromments on estrus expression, follicular development, early embryonic survival, and pregnancy success rates. Combined with field trial data, this paper elaborates on the application effects of the novel gonadotropin-releasing hormone (GnRH) analogue buserelin in scenarios such as fixed-time artificial insemination synchronization, reducing early embryonic mortality, and treating ovarian cysts. The study confirmed that buserelin can significantly alleviate heat stress-induced reproductive damage, improve summer conception rates, and enhance overall reproductive efficiency in dairy cows by regulating the endocrine status, increasing progesterone concentrations, and improving oocyte quality and the uterine environment. This provided a scientifically based practical solution for reproductive management in large-scale farms during summer.

夏季高温引发的热应激是奶牛养殖效益的关键难题,不仅造成奶牛产奶量下滑,还会大幅度损伤母牛繁殖性能。本文系统梳理了热应激对奶牛生理机能、内分泌稳态及繁殖功能的损伤机制,重点分析高温环境对发情表现、卵泡发育、早期胚胎存活及妊娠成功率的负面影响;结合田间试验数据,阐述新型促性腺激素释放激素(GnRH)类似物布舍瑞林在同期定时输精、降低早期胚胎死亡率、治疗卵巢囊肿等场景的应用效果。研究证实,布舍瑞林可通过调控奶牛内分泌水平、提升孕酮浓度、改善卵母细胞质量与子宫繁育环境,显著缓解热应激带来的繁殖损伤,提升夏季奶牛受胎率与整体繁殖效率,为规模牧场夏季繁殖管控提供科学实操方案。

夏季高温引发的热应激是奶牛养殖效益的关键难题,不仅造成奶牛产奶量下滑,还会大幅度损伤母牛繁殖性能。本文系统梳理了热应激对奶牛生理机能、内分泌稳态及繁殖功能的损伤机制,重点分析高温环境对发情表现、卵泡发育、早期胚胎存活及妊娠成功率的负面影响;结合田间试验数据,阐述新型促性腺激素释放激素(GnRH)类似物布舍瑞林在同期定时输精、降低早期胚胎死亡率、治疗卵巢囊肿等场景的应用效果。研究证实,布舍瑞林可通过调控奶牛内分泌水平、提升孕酮浓度、改善卵母细胞质量与子宫繁育环境,显著缓解热应激带来的繁殖损伤,提升夏季奶牛受胎率与整体繁殖效率,为规模牧场夏季繁殖管控提供科学实操方案。

Heat stress caused by high temperatures in summer is a key challenge restricting the profitability of dairy farming. It not only reduces milk yield but also significantly impairs the reproductive performance of dairy cows. This paper systematically reviewed the mechanisms by which heat stress damages the physiological functions, endocrine homeostasis, and reproductive performance of dairy cows, with a focus on analyzing the negative effects of high-temperature enviromments on estrus expression, follicular development, early embryonic survival, and pregnancy success rates. Combined with field trial data, this paper elaborates on the application effects of the novel gonadotropin-releasing hormone (GnRH) analogue buserelin in scenarios such as fixed-time artificial insemination synchronization, reducing early embryonic mortality, and treating ovarian cysts. The study confirmed that buserelin can significantly alleviate heat stress-induced reproductive damage, improve summer conception rates, and enhance overall reproductive efficiency in dairy cows by regulating the endocrine status, increasing progesterone concentrations, and improving oocyte quality and the uterine environment. This provided a scientifically based practical solution for reproductive management in large-scale farms during summer.
