Indirect genetic effect model using feeding behaviour traits to define the degree of interaction between mates: an implementation in pigs growth rate
(Cambridge University Press, 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 ...
Rabbit Microbiota Changes Throughout the Intestinal Tract
(Frontiers Media, 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
(BMC, 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 ...
Genetic parameters and expected responses to selection for components of feed efficiency in a Duroc pig line
(BMC, 2017-12-01)
Background: Improving feed efciency (FE) is a key factor for any pig breeding company. Although this can be achieved by selection on an index of multi-trait best linear unbiased prediction of breeding ...
Indirect genetic effects on the relationships between production and feeding behaviour traits in growing Duroc pigs
(Cambridge University Press, 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 ...
Interaction of direct and social genetic effects with feeding regime in growing rabbits
(BMC, 2017-07-20)
Background: Most rabbit production farms apply feed restriction at fattening because of its protective efect against digestive diseases that afect growing rabbits. However, it leads to competitive ...
Use of group records of feed intake to select for feed efficiency in rabbit
(Wiley, 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 ...
Longitudinal analysis of direct and indirect effects on average daily gain in rabbits using a structured antedependence model
(BMC, 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 ...
Genetic parameters of sow feed efficiency during lactation and its underlying traits in a Duroc population
(Cambridge University Press, 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 ...
