Genetic parameters of sow feed efficiency during lactation and its underlying traits in a Duroc population
(animal, 2019-11-25) Genètica i Millora Animal
As a result of the genetic selection for prolificacy and the improvements in the environment and farms management, litter size has increased in the last few years so that energy requirements of the ...
Indirect genetic effects on the relationships between production and feeding behaviour traits in growing Duroc pigs
(Animal, 2019-10-01) Genètica i Millora Animal
Performance and feeding behaviour traits in growing pigs could be affected by social interaction effects when animals are raised in group. So, properly knowing the genetic correlations between direct ...
Networks of inbreeding coefficients in a selected population of rabbits
(Journal of Animal Breeding and Genetics, 2020-08-17) Genètica i Millora Animal
The correlation between pedigree and genomic‐based inbreeding coefficients is usually discussed in the literature. However, some of these correlations could be spurious. Using partial correlations and ...
Genome-wide association study for feed efficiency in collective cage-raised rabbits under full and restricted feeding
(Animal Genetics, 2020-07-22) Genètica i Millora Animal
Feed efficiency (FE) is one of the most economically and environmentally relevant traits in the animal production sector. The objective of this study was to gain knowledge about the genetic control of ...
Selection for feed efficiency using the social effects animal model in growing Duroc pigs: evaluation by simulation
(Genetics Selection Evolution, 2020-09-29) Genètica i Millora Animal
Background Traits recorded on animals that are raised in groups can be analysed with the social effects animal model (SAM). For multiple traits, this model specifies the genetic correlation structure ...
Breeding farm, level of feeding and presence of antibiotics in the feed influence rabbit cecal microbiota
(Animal Microbiome, 2020-11-02) Genètica i Millora Animal; Gestió Integral de Residus Orgànics
Background The effect of the production environment and different management practices in rabbit cecal microbiota remains poorly understood. While previous studies have proved the impact of the age or ...
