Heritability Estimates for Conformation Traits in Pigs
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 n...
متن کاملEstimates of Repeatability and Heritability of Productive Trait in Holstein Dairy Cattle
Dairy cattle breeding programs have been based in the selection for traits related to milk production. In this research a data set of 63 herds of East Azerbaijan province Holstein cattle, collected during 2002-2013 by the Iranian Animal Breeding Center was used to estimate the repeatability and heritability of three traits of economic importance. Genetic parameters for first three lactations of...
متن کاملGenetic parameters for lean meat yield, meat quality, reproduction and feed efficiency traits for Australian pigs 1. Description of traits and heritability estimates
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...

متن کاملHeritability Estimates of Lactation Traits in Maltese Goat
Data on 657 lactation from 163 Maltese goat, collected over a 5-year period were analyzed by a mixed model to estimate the variance components for heritability. The considered lactation traits were: milk yield (MY) and lactation length (LL). Year, parity and type of birth (single or twin) were significant sources of variation for lactation length; on the other hand milk yield was significantly ...
