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 ...
Impact of multi-output and stacking methods on feed efficiency prediction from genotype using machine learning algorithms
(Wiley, 2023-07-05)
Feeding represents the largest economic cost in meat production; therefore, selection to improve traits related to feed efficiency is a goal in most livestock breeding programs. Residual feed intake ...
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 ...
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 ...
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 ...
The value of gut microbiota to predict feed efficiency and growth of rabbits under different feeding regimes
(Nature Research, 2021-09-30)
Gut microbiota plays an important role in nutrient absorption and could impact rabbit feed efciency.
This study aims at investigating such impact by evaluating the value added by microbial information
for ...
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 ...
Feature Selection Stability and Accuracy of Prediction Models for Genomic Prediction of Residual Feed Intake in Pigs Using Machine Learning
(Frontiers Media, 2021-02-22)
Feature selection (FS, i.e., selection of a subset of predictor variables) is essential in high-dimensional datasets to prevent overfitting of prediction/classification models and reduce computation ...
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 ...
