科学领域:

  • 牛肉牛的繁殖管理
  • 动物科学和育种策略动物科学和育种策略

背景情况:

  • 雌性同步协议可以导致缩的雌性期.
  • 在很短的时间内增加的增加给公牛的生育能力和群体管理带来了挑战.
  • 繁殖公牛的健全性对于成功的自然服务至关重要.

研究的目的:

  • 评估在期同步期间管理牛资源的策略.
  • 为同步的牛群推适当的公牛与牛的比例.
  • 确保肉牛的有效和及时受孕率.

主要方法:

  • 审视雌性同步协议及其对雌性表达的影响.
  • 分析公牛年龄及其对怀孕率的影响.
  • 根据成熟度和生育能力,确定最佳的公牛与牛的比例.

主要成果:

  • 成熟的公牛 (≥3岁) 与年轻的公牛相比,表现出更高的受孕效率.
  • 一个成年公牛对25头牛的比率被确定为同步群体的有效率.
  • 协议的选择应旨在在更长的时间内分配.

结论:

  • 仔细选择雌性同步协议可以减轻牛压力.
  • 使用成熟的公牛和适当的比例可以提高生殖效率.
  • 在同步繁殖之前,对公牛进行繁殖健康检查是必不可少的.
