Accuracy of genome-enabled prediction exploring purebred and crossbred pig populations.
Pig breeding companies keep relatively small populations of pure sire and dam lines that are selected to improve the performance of crossbred animals. This design of the pig breeding industry presents challenges to the implementation of genomic selection, which requires large data sets to obtain highly accurate genomic breeding values. The objective of this study was to evaluate the impact of d...
متن کاملAccuracy of Predicted Genomic Breeding Values in Purebred and Crossbred Pigs
Genomic selection has been widely implemented in dairy cattle breeding when the aim is to improve performance of purebred animals. In pigs, however, the final product is a crossbred animal. This may affect the efficiency of methods that are currently implemented for dairy cattle. Therefore, the objective of this study was to determine the accuracy of predicted breeding values in crossbred pigs ...
متن کاملReproductive and testicular characteristics of purebred and crossbred boars.
Purebred Hampshire, Duroc and crossbred (H x D, D x H) boars were studied to evaluate reproductive characteristics. One hundred seventeen boars were castrated at 7Y:! months of age to evaluate testicular weights and sperm numbers. Seventy-eight additional boars were studied to evaluate conception rate and embryo numbers when mated to Yorkshire gilts. Rate of gain and backfat probe were also ava...
متن کاملGrowth performance for four breeds of swine: crossbred females and purebred and crossbred boars.
Purebred and two-breed cross (F1) boars were mated to F1 females to produce all possible three- and four-breed cross pigs involving the Duroc, Yorkshire, Landrace and Spotted breeds. Individual postweaning average daily gain (ADG), age at 100 kg (AGE) and probed backfat thickness at 100 kg (BF) data were collected on 3,456 pigs. A total of 213 pens with an average of 15.58 pigs per pen was eval...
متن کاملGenetic Correlations between the Performance of Purebred and Crossbred Pigs
Genetic correlations between purebred Duroc (DU), Large White (LW) and Landrace (LR) pigs and their crossbreds LW×LR, LR×LW, DU×(LW×LR) and DU×(LR×LW) were estimated for production and reproduction traits. Performance test and litter records from Government pig breeding stations in Thailand were used. REML bivariate animal models were used to estimate genetic correlations for each trait measure...
