Snyman, M.A.Erasmus, G.J.Wyk, J.B. vanOlivier, J.J.[Genetic and phenotypic correlations among production and reproduction traits in Afrino sheep]Genetic and phenotypic correlations among production and reproduction traits in Afrino sheep

Data obtained through the Angora goat perfornance testing pilot scheme, run by the Department of Agriculture at the Grootfontein Agricultural Development Institute, were analyzed. Data of kids born from 1990 until 1993 in 17 studs were used in the analysis. Traits analyzed were body weight (BW; n...


Snyman, M.A.Olivier, J.J.[Genetic parameters for body weight, fleece weight and fibre diameter in South African Angora goats]Genetic parameters for body weight, fleece weight and fibre diameter in South African Angora goats
Herselman, M.J.Olivier, J.J.Snyman, M.A.[Studies on small ruminant breeds with inherent differences in fibre production and ewe productivity. 1. Relationship between ewe productivity and wool production potential]Studies on small ruminant breeds with inherent differences in fibre production and ewe productivity. 1. Relationship between ewe productivity and wool production potential

Data of 5342 progeny from 232 sires from 30 genetically linked flocks, collected through the National Progeny Testing program for Merino sheep from 1991 to 1996, were used to estimate heritabilities for several production and type traits. The traits analysed were: body weight (BW), clean fleece ...


Groenewald, P.G.J.Olivier, J.J.Olivier, W.J.[Heritability estimates for Merino sheep obtained from a national progeny test]Heritability estimates for Merino sheep obtained from a national progeny test

The repeatability and heritability of body weight, greasy fleece weight and mean fibre diameter, as well as various subjective fleece traits of South African Angora goats were estimated. The first of two data sets analysed, was collected through the Angora goat performance-testing scheme (AGPTS),...


Snyman, M.A.Olivier, J.J.[Repeatability and heritability of objective and subjective fleece traits and body weight in South African Angora goats]Repeatability and heritability of objective and subjective fleece traits and body weight in South African Angora goats

This study was undertaken to investigate the genetic stability of an unselected Conlrol Group of South African Merino sheep and genetic change in a flock selected for increased clean fleece mass (Selection Group) under the same environmental conditions. Data regarding 14-17 months clean fleece ma...


Cloete, S.W.P.Delport, G.J.Erasmus, G.J.Olivier, J.J.Heydenrych, H.J.Toit, Elizabeth du[Environmental and genetic trends in clean fleece mass, live mass and fiber diameter in selection and control flocks involving a selection experiment for increased clean fleece mass in South African Merino sheep]Environmental and genetic trends in clean fleece mass, live mass and fiber diameter in selection and control flocks involving a selection experiment for increased clean fleece mass in South African Merino sheep
