【摘要】 南方很多省份的肉牛以散养为主,常导致母牛配种不及时,受胎率低、存栏母牛有下降趋势。研发了肉牛冷配计算机管理系统,对发情(乏情)预报、发情控制以及冷配员日常工作等进行计算机管理、分析与决策。冷配员按规范记录日常工作数据,逐步输入计算机,利用软件制定的日常工作计划实施冷配:1)对发情正常的空怀母牛,通过软件准确预报有效黄体期,实施1次PG同期发情技术,同期发情率高于直肠检查组的;2)对乏情母牛,既实现了不通过直肠检查尽早发现、及时治疗缩短产犊间隔的目的,又获得了较高的受胎率;3)彻底改变了冷配员工作的被动性、增加了供冷配牛源的比例、规范了母牛繁殖记录,通过经济效益促进了牛繁殖数据记录的持续开展。更多还原

【Abstract】 In some provinces of south China beef cattle are raised dispersively,resulted that the pubescent cows could not be inseminated at the right time but the breeder has nothing to do at the same time.The number of beef cattle in countryside tends to be reduced because of the low breeding efficiency.Artificial insemination(AI) computer software of beef cattle was developed,the pubescent or anestrus cows could be predicted,the work plan for estrus synchronization and daily breeding work for AI were arranged automatically.The standard information of cows made by breeder was input to computer day by day and the breeder worked according to the plan made by the software.It indicated that:1) To the regularly estrus cows the result of estrus using PG and software’s prediction of the corpus luteum state,was much more better than that of controls using rectal examination(RE);2) To the anestrus cows it could be found and cured immediately without RE at the same time;3) The ratio of AI,the records of the cows were standardized,fully used,and continued.更多还原
