Housing system, milk production, and zero-grazing effects on lameness and leg injury in dairy cows.
TLDR
The results indicate that housing cows throughout the year potentially has a detrimental effect on foot and leg health, however, good free-stall design may reduce lameness and leg lesions.
The welfare implications of large litter size in the domestic pig I: biological factors
TLDR
It is concluded that, in a number of ways, large litter size is a risk factor for decreased animal welfare in pig production and possible biological approaches to mitigating health and welfare issues associated with large litters are being implemented.
Assessing the ‘whole animal’: a free choice profiling approach
The qualitative assessment of animal behaviour summarizes the different aspects of an animal's dynamic style of interaction with the environment, using descriptors such as ‘confident’, ‘nervous’,
Injurious tail biting in pigs: how can it be controlled in existing systems without tail docking?
TLDR
A quantitative comparison of the efficacy of different methods of provision of manipulable materials, and a review of current practices in countries and assurance schemes where tail docking is banned, both suggest that daily provision of small quantities of destructible, manipULable natural materials can be of considerable benefit.
Genetic validation of postmixing skin injuries in pigs as an indicator of aggressiveness and the relationship with injuries under more stable social conditions.
TLDR
Positive correlations between LC 24 h and 3 wk after mixing were found, indicating that postmixing lesions are predictive of those received under more stable group conditions and a genetic merit index using lesions to the anterior region as one trait and those to the center or rear or both as a second trait should allow selection against animals involved in reciprocal fighting and the delivery of NRA.
