Purchasing decisions are complex because, even though some consumers prefer meat with no fat in sight, they prefer the meat with the highest marbling degree when they taste it.
Traits of high or moderate heritability are easily improved by testing and selection. However, for traits of low heritability, improvements come from exploiting heterosis and by the use of BLUP.
Benefits and risks of heterosis and inbreeding in pig production.
We can predict a sow's production based on the number of piglets born alive at first farrowing. In addition, the best sows' performance will outdo the others' continuously.
This tool allows us to model the growth of animal body tissues in vivo and to study the effect of different factors (genetics, gender, nutrition) on this growth.
This article explains how the massive use of hormones helps synchronize heats and farrowings when workload scheduling, synchronization and production rates stability are priorities.
A strict schedule allows us to concentrate all the important events, and time periods where more attention/work is required, within the working days.
Although piglet birth weight is the most influential factor affecting piglet survival other behavioral factors such as vitality and vigor of piglets at birth contribute to the overall likelihood of the offspring surviving.
