Genetic selection may be used to control pathogen susceptibility and the composition of the gut microbiota

Genetic selection provides a powerful tool to improve and maintain gut health in industrial pig production, and may in the future become a more sustainable alternative to the currently massive need for antibiotics.

Do nurse sows and foster litters have impaired animal welfare?

The results show that nurse sows and their piglets to some extent experience more welfare problems than non-nurse sows with piglets at a similar age.

Interval from last insemination to culling: Culling reasons from practise and the correlation with longevity

This study showed the potential to select on longer interval from last insemination to culling in days and thereby select against sows to be culled within the reproduction, locomotion, accident, general disorder and peri-partum cull class and to be culled at the end of a parity.

Pre-lactation nutrition strategies for optimal sow and piglet performance

The evolution of genetics in modern sows requires nutritionists to evolve their diets and feeding programs accordingly. Nutritionist need to consider not only the role of nutrition on metabolism but also on hormone regulation and subsequent reproduction.
