Data of the Tygerhoek Merino flock were used to obtain estimates of genetic correlations of 18 months wool and pre-mating live mass traits with average reproduction over two to five lambing opportunities, as well as between pre-mating live mass and…
The effect of lupin supplementation during mating on the reproduction of autumn-lambing Merino ewes was studied relative to an unsupplemented control group. A total of 158 ewes were available for lambing in 1985, 229 in 1987 and 185 in 1988.…
An experiment was conducted to determine whether sugar could successfully be incorporated into feeds for ducklings in the period 0 to 7 weeks of age. Five dietary treatments, with sugar content ranging from 0 to 400 g kg-1 were fed…
This study was undertaken to investigate the genetic stability of an unselected Control 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…
