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 ...
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 ...
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 ...
Breeding programmes to improve male reproductive performance and efficiency of insemination dose production in paternal lines: feasibility and limitations
(Universidad Politécnica de Valencia, 2013-06-26)
This paper reviews the current genetic knowledge on issues related with the efficient use of bucks
in artificial insemination (AI). Differences between lines have been found to be relevant in semen ...
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 ...
Bayesian hierarchical model for comparison of different nonlinear function and genetic parameter estimates of meat quails
(Oxford University Press, 2018-12-07)
This study aimed to compare different nonlinear functions to describe the growth curve of European quails and to estimate growth curve parameters, (co)variance components, and genetic and systematic ...
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 ...
