Overview

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%)

What were the highlights of his more recent work (between 2009-2021)?

  • Animal science (82.11%)
  • Heritability (49.47%)
  • Genetic correlation (26.32%)

In recent papers he was focusing on the following fields of study:

J.B. van Wyk mainly investigates Animal science, Heritability, Genetic correlation, Breed and Sire. The Animal science study combines topics in areas such as Ecology, Flock and Reproduction. His Heritability research includes themes of Statistics, Threshold model, Animal breeding and Beef cattle.

His Genetic correlation research incorporates elements of Body weight and Genetic diversity. His work is dedicated to discovering how Breed, Herd are connected with Rump and Dohne Merino and other disciplines. Inbreeding is closely connected to Genetics in his research, which is encompassed under the umbrella topic of Sire.

Between 2009 and 2021, his most popular works were:

  • South African sheep breeds: Population genetic structure and conservation implications (30 citations)
  • Estimation of genetic and phenotypic parameters of growth curve and their relationship with early growth and productivity in Horro sheep (21 citations)
  • Genetic (co)variances between wrinkle score and absence of breech strike in mulesed and unmulesed Merino sheep, using a threshold model (19 citations)

In his most recent research, the most cited papers focused on:

  • Genetics
  • Ecology
  • Animal science

The scientist’s investigation covers issues in Animal science, Genetic correlation, Heritability, Ecology and Reproduction. His work blends Animal science and Soil indicators studies together. His Genetic correlation research includes elements of Breed and Likelihood-ratio test.

J.B. van Wyk performs integrative study on Heritability and Weaning weight. His Ecology research is multidisciplinary, incorporating perspectives in Genetic distance and Genetic structure. The various areas that J.B. van Wyk examines in his Reproduction study include Base population, Seasonal breeder, Flock, Sire and Additive genetic effects.
