Use of group records of feed intake to select for feed efficiency in rabbit
(Journal of Animal Breeding and Genetics, 2019-04-24)
Models for genetic evaluation of feed efficiency (FE) for animals housed in groups when they are either fed ad libitum (F) or on restricted (R) feeding were implemented. Definitions of FE on F included ...
Genetic parameters of sow feed efficiency during lactation and its underlying traits in a Duroc population
(animal, 2019-11-25)
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)
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 ...
Indirect genetic effect model using feeding behaviour traits to define the degree of interaction between mates: an implementation in pigs growth rate
(Animal, 2018-06-06)
An alternative implementation of the animal model including indirect genetic effect (IGE) is presented considering pair-mate-specific interaction degrees to improve the performance of the model. Data ...
Longitudinal analysis of direct and indirect effects on average daily gain in rabbits using a structured antedependence model
(Genetics Selection Evolution, 2018-05-10)
Background: Indirect genetic efects (IGE) are important components of various traits in several species. Although
the intensity of social interactions between partners likely vary over time, very few ...
Rabbit Microbiota Changes Throughout the Intestinal Tract
(Frontiers in Microbiology, 2018-09-13)
To gain insight into the importance of carefully selecting the sampling area for intestinal
microbiota studies, cecal and fecal microbial communities of Caldes meat rabbit were
characterized. The ...
Efect of feed restriction on the environmental variability of birth weight in divergently selected lines of mice
(Genetics Selection Evolution, 2019-06-13)
Selection of mice for decreased environmental variability of birth weight has achieved higher survivability and larger litter size as a correlated response to canalized selection, which suggests higher ...
Are Consumers’ Egg Preferences Influenced by Animal-Welfare Conditions and Environmental Impacts?
(Sustainability, 2019-11-06)
We conducted a labelled discrete choice experiment (DCE) to assess consumers’ preferences and willingness to pay (WTP) for fresh hens’ eggs produced via different production systems (caged, barn, free ...
Networks of inbreeding coefficients in a selected population of rabbits
(Journal of Animal Breeding and Genetics, 2020-08-17)
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)
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 ...
