Genetic parameters of 16 pelt traits and birth mass were calculated in a Karakul control flock (n = 2058; rams = 305) with a half-sib analysis. Moderately high heritabilities were estimated for pelt traits. No antagonistic genetic correlation was found…
Pelts of 2465 lambs from a randomly bred Karakul flock were subjectively evaluated within 24 h after birth, over a two-year period. The data were analysed with year of birth, birth status, month born, age of the dam and sex…
Correlated responses of curl development, hair quality, hair thickness, hair stiffness, hair length, lustre and pattern to selection for an increase in pattern and hair quality and a decrease in hair length and curl development were determined with mixed model…
The study was undertaken to assess the influence of various environmental effects, e.g. sex, age of dam, month of birth and mating types (black X black, black X grey, grey X black and grey X grey) on pelt traits of…
Genetic trends owing to selection for an increase in pattern and hair quality and a decrease in hair length and curl development in the Karakul were estimated with the Animal Model in four selection lines and in a control flock…
A total of 967 animal records, of subjective trait scores, obtained between 1989 and 1990, from the control flock at the Karakul Research Station near Upington were used to evaluate 20 pelt traits in Karakul sheep, applying linear and threshold…
