A breed-of-origin of alleles model that includes crossbred data improves predictive ability for crossbred animals in a multi-breed population

Genetics Selection Evolution, 2023
Background Recently, crossbred animals have begun to be used as parents in the next generations of dairy and beef cattle systems, which has increased the interest in predicting the genetic merit of those animals.

Breed of origin of alleles and genomic predictions for crossbred dairy cows

Genetics Selection Evolution, 2021
Background In dairy cattle, genomic selection has been implemented successfully for purebred populations, but, to date, genomic estimated breeding values (GEBV) for crossbred cows are rarely available, although they are valuable for rotational ...

Genetic parameters and genomic prediction for feed intake recorded at the group and individual level in different production systems for growing pigs

Genetics Selection Evolution, 2021
Background In breeding programs, recording large-scale feed intake (FI) data routinely at the individual level is costly and difficult compared with other production traits.

Effect of genomic selection and genotyping strategy on estimation of variance components in animal models using different relationship matrices

Genetics Selection Evolution, 2020
Background The traditional way to estimate variance components (VC) is based on the animal model using a pedigree-based relationship matrix (A) (A-AM).

Supervised learning techniques for dairy cattle body weight prediction from 3D digital images

Frontiers in Genetics, 2023
Introduction: The use of automation and sensor-based systems in livestock production allows monitoring of individual cows in real-time and provides the possibility of early warning systems to take necessary management actions against possible anomalies ...

Estimation and consequences of direct-maternal genetic and environmental covariances in models for genetic evaluation in broilers

Genetics Selection Evolution, 2023
Background Maternal effects influence juvenile traits such as body weight and early growth in broilers. Ignoring significant maternal effects leads to reduced accuracy and inflated predicted breeding values.

Pre-selection against a lethal recessive allele in breeding schemes with optimum-contribution selection or truncation selection

Genetics Selection Evolution, 2021
Background We tested the hypothesis that breeding schemes with a pre-selection step, in which carriers of a lethal recessive allele (LRA) were culled, and with optimum-contribution selection (OCS) reduce the frequency of a LRA, control rate of inbreeding,
