Genetic Parameters in Merino Sheep GENETIC RELATIONSHIPS BETWEEN CARCASS QUALITY AND WOOL PRODUCTION TRAITS IN AUSTRALIAN MERINO RAMS
The heritability of carcass quality traits and the genetic correlations between wool production and these carcass quality traits were estimated on 1216 Merino rams. The results showed that carcass quality traits are moderately heritable but pH appears to be lowly heritable. Yellowness and redness of L. dorsi had very low heritability estimate. Moderate negative genetic relationships were found ...
متن کاملgenetic relationship and the possibility of inter species breeding between domestic sheep (ovis aries) and wild sheep (ovis orientalis isphahanica)
introduction: cloning an individual by transferring somatic nuclei into enucleated recipient oocytes has already been well established. this technology also offers new opportunities to restore threatened species with interspecies somatic cell nuclear transfer (scnt). however, few mammalian species have been studied for their reproductive biology whereas huge differences have been observed betwe...
متن کاملFaecal glucocorticoid metabolites and body temperature in Australian merino ewes (Ovis aries) during summer artificial insemination (AI) program
Reproductive wastage is a key issue for sheep producers, both regionally and globally. The reproductive output of farm animals can be influenced by physiological and environmental factors. Rapid and reliable quantification of physiological stress can provide a useful tool for designing and testing on-farm management interventions to improve farm animal welfare and productivity. In this study, w...
متن کاملRetardation of wool growth in Merino sheep caused by bacteria.
A condition evidenced by retarded growth of wool with alteration of the yolk into a yellow, sticky, wax-like substance was investigated. The condition was associated with hyperaemia and cellular infiltration into the dermis in the affected areas. Three bacterial species, viz. Enterobacter aerogenes, E. agglomerans and Hafnia alvei, which could grow on the water-extractable component of wool-yol...
متن کاملNeuronal Ceroid Lipofuscinosis in Australian Merino Sheep
The neuronal ceroid lipofuscinoses (NCLs) are a group of inherited neurodegenerative diseases characterised by the accumulation of autofluorescent lipopigment in a variety of tissues. At least six different forms of NCL occur in humans and the disease has been identified in various animal species, including sheep. Clinical features of NCL are dementia, loss of vision, motor disturbances, and pr...
