牛发情特异信息素的研究进展

发情鉴定一直无法突破安静发情鉴定瓶颈,严重制约了奶牛养殖产业发展.关于信息素的研究为通过仿生学办法促进母牛发情鉴定技术创新提供了新思路.对公、母牛交配的观察显示,公、母牛交配前发情母牛间都存在明显的性嗅反射,这表明除性器官的感官刺激外,公、母畜间还存在较强的信息素交流,这种方式早已在蜜蜂、蚕蛾等物种中得到了证实.因此,...

Study Progress on Specific Pheromones of Bovine during Oestrus

Silent estrus has been the bottleneck of estrus identification, which seriously impedes the development of dairy farming industry. The research on pheromone provides a new idea for promoting the technical innovation of cow estrus detection through the way of bionics. The observation of mating between male and female cattle shows that there is an obvious flehmen between estrous cows before mating, which indicates that there is stronger pheromone communication between male and female animals in addition to sensory stimulation of sexual organs, which has been confirmed in bees and silkworm moths. Therefore, this paper reviews the study on pheromones from bovine feces, urine, vaginal mucus, milk, saliva and so on, hoping to provide an important reference for further revealing the pheromone secretion rule of estrous cows, so as to promote the research and development of timely and accurate estrous identification technology of cows in non-invasive manner.
