The Dorper is a hardy South African composite breed, derived from a cross between the Black-headed Persian and the Dorset Horn. Dorpers are regarded as early-maturing, and ewes lambed at an age of 1 year in one study. Age at first lambing was higher in other literature sources cited. The fertilit...

The reproductive performance, growth, slaughter traits, and several conformation characteristics in Dorper sheep (hair and wool types) were evaluated under extensive conditions in the north-western Karoo region of South Africa. From 1993 to 2000, lambs of hair (n=1070) and wool (n=1044) type Dorp...

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...

Relationship between ewe productivity and wool production potential

Data, consisiting of 4235 lamb records, obtained from the Foundation Afrino Sheep stud at the Carnarvon Experimental station, were used to investigate factors influencing birth weight, weaning weight, monthly body weight from five to 12 months, body weight at 18 months of age as well as clean fle...

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),...
