概括

群体规模会影响猪尾伤害,较小的群体会遭受更严重的伤害. 较大群体的尾部受伤程度较小,但受影响的猪总数仍然相似.

科学领域:

动物科学动物科学
动物福利动物福利
农业科学农业科学

背景情况:

咬尾巴是密集生猪养殖中一个重要的福利问题.
了解影响尾部损伤的因素对于改善猪健康至关重要.
关于小组大小对猪尾部损伤的影响的先前研究是多样化的.

研究的目的:

调查群体大小对尾巴损伤严重程度和成长表现的影响.
为了比较小型和大型群体住房系统之间的尾部伤害发生率和严重程度.
评估群体规模和猪生长指标之间的关系.

主要方法:

432只成长的猪被分成小群 (9只猪/圈) 或大群 (18只猪/圈).
猪从9周到23周的年龄,每周在5分级上监测尾部受伤情况.
记录了生长表现 (平均每日增长,料摄入量,料增长比率).

主要成果:

群体大小没有影响平均每日增益,料摄入量或料增益比.
在小群的猪中,尾部受伤的频率和严重性更高,导致更高的移除率.
大群的猪表现出更多的治愈的尾巴分数或轻微的伤害,更少的移除.

结论:

虽然小组大小会影响尾部损伤的严重程度,但它并没有影响本研究中的整体生长表现.
管理群体大小可以作为一种策略,以减轻与完整的尾巴养的猪严重的尾巴损伤.
需要进一步的研究来探索环境的丰富性以及群体大小,以获得最佳的猪福利.
