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 ...
Novel phenotypes of feeding and social behaviour and their relationship with individual rabbit growth and feed efficiency
(Elsevier, 2024-01-30)
Due to the lack of a recording system for individual consumption of group-housed rabbits, published studies about feeding behaviour are based on information recorded at the group- and not at the individual ...
Inbreeding depression on growth and prolificacy traits in two lines of rabbit
(Wiley, 2022-10-26)
Inbreeding depression in closed populations impairs animal fitness, health, and productivity. However, not all inbreeding is expected to be equally damaging. Recent inbreeding is thought to be more ...
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 ...
Disentangling the causal relationship between rabbit growth and cecal microbiota through structural equation models
(BMC, 2022-12-19)
Background
The effect of the cecal microbiome on growth of rabbits that were fed under different regimes has been studied previously. However, the term “effect” carries a causal meaning that can be ...
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 ...
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) ...
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 ...
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 ...
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 ...
