METABOLIC PROCESSES IN PUREBRED AND CROSSBRED PIGS AT DIFFERENT AGE PERIODS

Genetic 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...

Accuracy 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 ...

Adjustment of 21-day Litter Weight for Number of Pigs Nursed for Purebred and Crossbred Dams

Comparison of Meat Quality and Fatty Acid Composition of Longissimus Muscles from Purebred Pigs and Three-way Crossbred LYD Pigs

This study was conducted to find pork quality to meet the needs of consumers. Thus, the meat quality and fatty acid composition of longissimus muscles from purebred pigs (Landrace, Yorkshire, and Duroc) and three-way crossbred LYD pigs were compared and evaluated. Chemical compositions of longissimus muscles were significant (p<0.05) different among pigs. Duroc contained significant (p<0.05) hi...

Circulating metabolic biomarkers and hormones and their relationships at different pre- and post-parturition periods of Ghezel ewes

Information regarding metabolic profile in different physiological periods of ewes can assist veterinarians to monitor the herd health and productive performance. Furthermore, the relationships among the metabolic parameters can be used to detect the effect of each parameter on another one. Five clinically healthy adult Ghezel ewes were selected at 4 weeks before parturition and evaluated at 4 ...
