Mate Choice

11.7K
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

  • 为在生猪生产中开发以福利为中心的精密照明提供见解.
  • 调查对不同光谱和强度的行为反应.

主要方法:

  • 为了光谱控制,开发了一种具有RGBW-LED的动态多色彩自选系统.
  • 二十四只被安置了五周,可以自由进入白色,黄色,绿色,蓝色和红色光区 (100卢克斯).
  • 一个YOLOv8n深度学习框架实时量化了黄金的分布,活动和饮食行为.

主要成果:

  • 吉尔特对绿光有显著的偏好 (21.29%的分布),特别是在特定的白天和晚上的时间段.
  • 平均金活性在白光下最高 (25.49%),明显高于黄色或绿光.
  • 每日料消耗在绿光下最低,明显低于白色,蓝色或红色光下.

结论:

  • 喜欢绿灯环境,这可能表明压力减少或舒适度提高.
  • 白光可以促进更高的活动水平,这可能对某些生产阶段有利.
  • 操纵浅色为改善黄金福利提供了一个有希望的途径,并可能影响猪生产中的养模式.
