Heritability Estimates for Conformation Traits in Pigs
نویسنده
چکیده
Data from 1006 pigs selected for breeding and subsequently scored at 22-24 weeks of age were used to estimate heritabilities for conformation traits. Front wrists, front pasterns, back hocks, back pasterns, front view, rear view and back shape were each subjectively scored by a single operator. For the individual traits heritability estimates ranged from high (0.42±0.09 for front pasterns) to negligible (0.01±0.04 for back hocks and body shape). Results suggest that at least some individual conformation traits (eg. front wrists and pasterns; back pasterns) would respond to selection, whereas other conformation traits (eg. hocks, front and rear views, or shape) are less likely to.

Data from 1799 Large White and 1522 Landrace boars were used to obtain heritability and litter effect estimates for performance, carcass and meat quality traits applying a REML procedure fitting an animal model. Analysed traits included average daily gain from three to 18 weeks of age (ADG1) and average daily gain, feed intake and feed conversion ratio from 18 to 22 weeks of age. Carcass traits...

This study was conducted to estimate the genetic parameters for pork belly traits and muscles in Yorkshire pigs. Each pork belly was cut into nine parts perpendicular to the thoracic vertebrae (6th to 14th). Traits of belly muscles including the deep pectoral, latissimus dorsi, cutaneous trunci, rectus abdominis, external and internal abdominal oblique from 382 purebred pigs were recorded and a...
