摘要:

简便有效的早期妊娠诊断技术是提高管理效率和养殖经济效益的根本要求,已建立多种早期妊娠诊断方法,对于及时发现空怀母牛并安排配种,提高繁殖效率具有重要意义。本文从技术难度、繁琐程度、成本、精确程度等方面,比较分析了直肠检查、超声波检查等临床诊断法和孕酮、早期妊娠因子等免疫诊断方法,以及血清酸滴定和血小板计数等其他妊娠检测方法。随着奶牛养殖规模化、集约化程度不断增加,现有妊娠诊断方法越来越不适应产业发展形势,信息与传感技术等与产业结合已成为必然趋势,深入研究奶牛发情期生理特性,将为这些技术与产业结合奠定必要的前提条件,并将大大提高繁殖管理的精细化程度。

Abstract:

A simple and effective technique of early pregnancy diagnosis could help to pick out nonpregnant cows in time and re-inseminate as early as possible,thereby lead to the improvement of reproductive efficiency,which was the basic requirement of efficient livestock breeding management and reproductive performance improvement.For this reason,pregnancy diagnoses were explored and many early pregnancy diagnoses had been established: the clinical diagnostics methods such as rectal palpation and ultrasonography,immunologic diagnosis such as progesterone and early pregnancy factor detection,and other methods such as serum acid titration and coulter thrombocytometry.We analyzed and compared all these methods from the technical difficulty,complexity,cost,and accuracy.These analysis results showed that with the development of the technology,the dairy industry were becoming large-scale and intensive,and the existing pregnancy diagnoses were not adapt to the situation of industrial development.The combination of information and sensor technology had become an inevitable trend.It was necessary to extensively studied the physiological characteristics of cows in estrus for the combination of technique and industry,and the fine degree of breeding management would be greatly improved.
