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 ...
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 ...
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 ...
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 ...
Genome-wide association study for feed efficiency in collective cage-raised rabbits under full and restricted feeding
(Wiley, 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 ...
Genic and non-genic SNP contributions to additive and dominance genetic effects in purebred and crossbred pig traits
(Nature Research, 2022-03-09)
The present research has estimated the additive and dominance genetic variances of genic and intergenic segments for average daily gain (ADG), backfat thickness (BFT) and pH of the semimembranosus dorsi ...
