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 ...
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 ...
Selection for feed efficiency using the social effects animal model in growing Duroc pigs: evaluation by simulation
(BMC, 2020-09-29)
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 ...
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 ...
Analysis of the causal structure of traits involved in sow lactation feed efficiency
(BMC, 2022-07-26)
Background
Feed efficiency during lactation involves a set of phenotypic traits that form a complex system, with some traits exerting causal effects on the others. Information regarding such ...
Use of Bayes factors to evaluate the effects of host genetics, litter and cage on the rabbit cecal microbiota
(BMC, 2022-06-27)
Background
The rabbit cecum hosts and interacts with a complex microbial ecosystem that contributes to the variation of traits of economic interest. Although the influence of host genetics on microbial ...
Social network analysis of agonistic behaviour and its association with economically important traits in pigs
(MDPI, 2020-11-16)
Aggression behaviour has several negative consequences on the performance and welfare of pigs. Here, the Social Network Analysis (SNA) approach was employed to (1) identify individual traits that describe ...
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 ...
Longitudinal modelling of performance and feed efficiency traits in growing Duroc pigs
(Elsevier, 2022-01-07)
In this study we used the phenotypic information of 1,499 Duroc pigs, recorded longitudinally in the age period from 110 to 200 days of age for individual daily feed intake (DFI), backfat thickness (BF) ...
Breeding farm, level of feeding and presence of antibiotics in the feed influence rabbit cecal microbiota
(BMC, 2020-11-02)
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 ...
