Generating breeding programmes that effectively improve farmed fish performance across
multiple environments and make fish more uniform within production environments would …

Genetic control of residual variance offers opportunities to increase uniformity and resilience
of livestock and aquaculture species. Improving uniformity and resilience of animals will …

Introduction Litter size in pigs has increased steadily since 1990. Because of unfavorable
genetic correlations with piglet mortality, breeding goals should include survival traits next to …

Background In many traits, not only individual trait levels are under genetic control, but also
the variation around that level. In other words, genotypes do not only differ in mean, but also …

Background The genetic background of trait variability has captured the interest of ecologists
and animal breeders because the genes that control it could be involved in buffering various …

Gradually increasing trend of litter size poses a challenge to pig farmers in terms of
managing larger litters. Therefore, it seems that a balanced approach that optimises litter …

Abstract Background In farmed Atlantic salmon, heritability for uniformity of body weight is
low, indicating that the accuracy of estimated breeding values (EBV) may be low. The use of …

Piglet mortality has a negative impact on animal welfare and public acceptance. Moreover,
the number of weaned piglets per sow mainly determines the profitability of piglet …

This study aimed to analyse genetic background of variation in reproductive performance
between parities of a sow and to investigate selection strategies to change the “parity curve” …

Reproductive traits are an integral part of the goals of the breeding programs that contribute
to the economic success of production. Reproductive phenotypes such as litter size, number …
