Personality types and teat order in piglets

Personality in piglets: Is there a difference in personality traits between pigs from different teat order positions?

Proceedings: The effect of apomorphine on oral behaviour in piglets.

The new-born mammal has both nutritive and non-nutritive sucking requirements (Levy, 1934). When non-nutritive sucking is prevented, abnormal oral behaviour which can resemble the effect of apomorphine may be induced. The two types of sucking behaviour can be distinguished using equipment described by Stephens (1975). This consists of a wooden box lined with rubber sheeting. A rubber teat is in...

Milk production in sows from a teat in second parity is influenced by whether it was suckled in first parity.

The impacts of a teat being suckled or not in first parity on its development, gene expression, and milk yield in the next parity were studied. Forty-seven first-parity sows (Sus scrofa) were divided into 2 groups: i) the same teats suckled in 2 subsequent lactations (controls, CTL; n = 22); and ii) different teats suckled in 2 subsequent lactations (treated, TRT; n = 25). In the first lactatio...

Observations on the Sucking Behaviour of Piglets in Litters of Varying Size

Impact of general injection anaesthesia and analgesia on post-castration behaviour and teat order of piglets.

Injection anaesthesia with a combination of ketamine and azaperone (K/A) is discussed as a painless alternative to commonly used non-anaesthetized castration. To protect anaesthetized piglets from being crushed, they have to be separated from the sow for 3 h following castration. The aim of this study was to test if this separation and the different treatments would affect short-term behaviour ...
