Breeding for disease resistance in Merino sheep in Australia.
Breeding for disease resistance in Merino sheep in Australia has attracted considerable research and development attention. Increased labour costs, the reduced efficacy of common anthelmintics and insecticides, consumer demand for products which are free of chemicals and the poor prognosis of alternative long-term control strategies are all forcing sheep breeders to contemplate the best animal ...
متن کاملA genome-wide scan to detect signatures of recent selection in Australian Merino sheep
Domestication and selection are processes that conserve the pattern of genetic diversities between and within populations. Identification of genomic regions that are targets of selection for phenotypic traits is one of the main aims of research in animal genetics. An approach for identifying divergently selected regions of the genome is to compare FST values among loci to estimate the genetic v...

متن کاملGenetic Parameters in Merino Sheep GENETIC PARAMETERS FOR ULTRASOUND SCAN AND WOOL TRAITS AT YEARLING AND HOGGET AGE IN MERINO SHEEP
The Australian Merino is the most important genetic resource for the wool and the lamb and sheep meat industries of Australia. In this paper estimated genetic parameters for ultrasound scan and wool traits at yearling and hogget age are presented for Merino sheep. Results indicate that it is possible to breed Merino sheep that perform well for both ultrasound scan and wool characteristics when ...
