Genetic parameters for birth difficulty, lamb vigour and lamb sucking ability in Suffolk sheep

This study investigates the genetic basis of lamb vigour (defined as neonatal lamb activity and sucking ability) and lambing difficulty as potential traits to be included in selection programmes to improve ewe and lamb welfare. Scores for lamb birth difficulty, vigour and sucking ability were collected shortly after birth on 1,520 lambs born in 2006 […]

Effect of a birth on the behavior of a family group of Asian elephants (Elephas maximus) at Dublin Zoo

Elephants in the wild live in herds of related females from several generations. Zoos, therefore, tend to house elephants in female groups, consisting where possible of related individuals.

Moreover, those sensations must be sufficiently noxious or aversive to cause suffering. The neural apparatus of […]
