ABSTRACT

We investigated the post-weaning effect of providing additional objects (i.e. rope, ball, tyre) to commercial piglets given straw pre- and post-weaning on behaviour and average daily gain (ADG). Piglets from litters with objects (O, n = 20 in 5 litters) and controls (C, n = 20 in 5 litters) were observed from 24 h post-weaning and during six days. Piglets were weighed at birth, weaning and 11 days post-weaning. O-piglets performed less littermate manipulation (P < 0.05), exploring pen fixtures (P < 0.1) and lying (P < 0.1) but spent more time in the creep post-weaning than C-piglets (P < 0.1). Social or locomotor play was expressed similarly in both treatments. Day strongly influenced the behaviour of pigs post-weaning. O-piglets had significantly lower pre-weaning ADG than C-piglets (P < 0.05), but there was no significant difference in post-weaning ADG between the treatments. Providing objects to piglets around weaning may reduce some negative behaviours, but may affect weight gain negatively.

摘要

我们调查了断奶前和断奶后给仔猪提供额外物体（例如，绳索，球，轮胎）的行为和平均日增重（ADG）后断奶后的效果。从 断奶后24小时和六天内观察到有对象（O，n  = 20分之5个窝）和对照（C，n = 20分之5个窝）的仔猪。仔猪在出生，断奶和断奶后11天称重。O型仔猪的同窝仔猪操作较少（P  <0.05），探索围栏固定物（P  <0.1）和躺着（P  <0.1），但断奶后的蠕动时间比C型仔猪（P <0.1）。两种治疗中社交或运动玩法的表达相似。一天对断奶后的猪的行为有很大影响。O型仔猪的断奶前ADG显着低于C型仔猪（P  <0.05），但两种治疗之间的断奶后ADG没有显着差异。在断奶前后向仔猪提供物体可能会减少一些负面行为，但可能会对体重增加产生负面影响。
