本文聚焦于安抚信息素在犊牛断奶过程中的应用;阐述了犊牛断奶应激的现状,包括断奶应激产生的原因、对犊牛生理和行为的不良影响,如引发皮质醇等应激激素释放,导致犊牛生长受阻、免疫力下降等问题;详细介绍了安抚信息素的作用机理,其通过鼻腔中的犁鼻器识别,传递信息到下丘脑,影响动物情绪和激素分泌,从而缓解犊牛断奶应激;结合多个实际研究案例,深入分析了安抚信息素在犊牛断奶中的应用效果,包括降低应激指标、提高日增重、减少疾病发生率等;探讨了安抚信息素应用的最佳方式和未来发展前景,为犊牛断奶应激管理提供了全面且科学的参考依据,有助于推动肉牛和奶牛养殖产业的健康发展。

This study focused on the application of appeasing pheromones during the weaning process of calves. It elaborated on the current status of weaning stress in calves,including the causes of weaning stress and its adverse effects on calf physiology and behavior,such as the release of stress hormones like cortisol,which lead to growth retardation and immune suppression. The mechanism of action of appeasing pheromones was detailed,explaining how they are recognized by the vomeronasal organ in the nasal cavity,transmit signals to the hypothalamus,and influence animal emotions and hormone secretion,thereby alleviating weaning stress in calves. Through multiple practical research cases,the application effects of appeasing pheromones in calf weaning were thoroughly analyzed,including the reduction of stress indicators,improvement in daily weight gain,and decreased disease incidence. The optimal application methods and future development prospects of appeasing pheromones were also discussed,providing comprehensive and scientific references for weaning stress management in calves and contributing to the healthy development of the beef and dairy cattle farming industries.
