What is he best known for?
The fields of study he is best known for:
- Genetics
- Ecology
- Animal science
His primary scientific interests are in Animal science, Heritability, Genetic correlation, Reproduction and Weaning.
In general Animal science study, his work on Breed often relates to the realm of Weaning weight, thereby connecting several areas of interest.
His Heritability study incorporates themes from Litter, Statistics, Variance components and Flock.
His Flock research is multidisciplinary, relying on both Body weight, Dorper sheep and Additive genetic effects.
J.B. van Wyk has researched Reproduction in several fields, including Domestic sheep reproduction and Sire.
J.B. van Wyk works mostly in the field of Weaning, limiting it down to topics relating to Biotechnology and, in certain cases, Standard error, as a part of the same area of interest.
His most cited work include:
- GENETIC PARAMETER ESTIMATES IN SABI SHEEP (136 citations)
- Direct and maternal (co) variance components and heritability estimates for body weight at different ages and fleece traits in Afrino sheep (127 citations)
- Genetic parameter estimates for pre-weaning weight traits in Dorper sheep. (90 citations)
What are the main themes of his work throughout his whole career to date?
His primary areas of investigation include Animal science, Heritability, Breed, Genetic correlation and Reproduction.
His research in Animal science tackles topics such as Flock which are related to areas like Indirect selection.
His study in Heritability is interdisciplinary in nature, drawing from both Statistics, Variance components, Biotechnology and Animal breeding.
His Breed study integrates concerns from other disciplines, such as Dairy cattle and Inbreeding, Inbreeding depression.
The concepts of his Reproduction study are interwoven with issues in Base population and Domestic sheep reproduction.
His work focuses on many connections between Weaning and other disciplines, such as Fertility, that overlap with his field of interest in Litter.
He most often published in these fields:
- Animal science (82.11%)
- Heritability (49.47%)
- Breed (27.37%)
