Factors affecting pre-weaning kid mortality in South African Angora goats
________________________________________________________________________________ Abstract The data used for this study were collected in 12 different Angora goat studs from 2000 to 2004. Data collected on 17534 kids born alive in the different studs were included in the analyses. Average pre-weaning mortality rate was 11.5% and ranged from 8.6% to 16.5% (of the 17534 kids born alive, 2018 kids ...

___________________________________________________________________________________ Abstract The data used for this study consisted of 27 485 kid records, the progeny of 599 sires and 10 077 dams, and were collected on the 2000to 2009-born kids of 11 Angora goat studs. Variance and covariance components and ratios pertaining to direct additive genetic variation, maternal additive genetic variat...
متن کاملGenetic variation of the reference population for quantitative trait loci research in South African Angora goats
The South African Angora goat industry makes the largest contribution to global mohair production. Mohair is a luxury fibre and production of a high quality clip is essential. For many years genetic improvement of Angoras in South Africa was based on quantitative selection. Genome mapping efforts provided new avenues for improvement and a quantitative trait loci (QTL) study was initiated to ide...
متن کاملGenetic Diversity and Population Structure in South African, French and Argentinian Angora Goats from Genome-Wide SNP Data
The Angora goat populations in Argentina (AR), France (FR) and South Africa (SA) have been kept geographically and genetically distinct. Due to country-specific selection and breeding strategies, there is a need to characterize the populations on a genetic level. In this study we analysed genetic variability of Angora goats from three distinct geographical regions using the standardized 50k Goa...
متن کاملBreeding Problems with Angora Goats
OINCE its domestication the goat has served man well. As a source of milk, meat, mohair, and skins it has furnished him both food and clothing, and because of its brush-eating proclivities, has spared him untold amounts of hard labor with the brush hook. Since 1900 the Angora goat industry in the United States has undergone rapid expansion. At present it is confined largely to the Southwestern ...
