Indirect genetic effect model using feeding behaviour traits to define the degree of interaction between mates: an implementation in pigs growth rate
(Cambridge University Press, 2018-06-06)
An alternative implementation of the animal model including indirect genetic effect (IGE) is presented considering pair-mate-specific interaction degrees to improve the performance of the model. Data ...
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 ...
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 ...
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) ...
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 ...
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 ...
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 ...
Machine Learning Prediction of Crossbred Pig Feed Efficiency and Growth Rate From Single Nucleotide Polymorphisms
(Frontiers Media, 2020-12-18)
This research assessed the ability of a Support Vector Machine (SVM) regression model to predict pig crossbred (CB) performance from various sources of phenotypic and genotypic information for improving ...
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 ...
