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 …

We estimated genetic parameters for two pork production and six litter performance traits of
Landrace, Large White, and Duroc pigs reared in Japan. Pork production traits were …

Background and Aim: A piglet's pre-weaning performance significantly influences both
animal welfare and profitability in pig production. Understanding piglet pre-weaning …

Background The herd age structure, ie, distribution of sows within a farm based on their
parity number, and its management are essential to optimizing farm reproductive efficiency …

The objective of this study was to obtain new phenotypes of phenotypic variability for the
total number born (TNB) in pigs using the residual variance of TNB. The analysis was based …

We estimated genetic parameters for number born alive (NBA) from the first to the seventh
parities in Landrace and Large White pigs using three models. Analyzing 55,160 farrowing …

Second litter syndrome (SLS) in sows is when fertility performance is lower in the second
parity than in the first parity. The causes of SLS have been associated with lactation weight …

Simple Summary In pig production, the ability of a sow to produce and rear a high number of
viable piglets that meet weight targets for a desired age at slaughter is the ultimate goal. To …

Simple Summary In the Republic of Serbia, pig selection in recent decades has been based
on genetic improvement of growth and carcass quality traits. Genetic improvement of …
