Effect of Ovine Growth Hormone Transgenesis on Performance of Merino Sheep at Pasture. 1. Growth and Wool Traits to 12 Months of Age
نویسندگان
چکیده
The effect of an ovine growth hormone transgene on body growth and wool production to 12 mo of age of Merino sheep at pasture was investigated. There was no effect of the transgene on growth to 3 mo of age. From 7 mo onwards, animals heterozygous for the transgene began to grow faster and were significantly heavier than those without the transgene. The pattern of growth response was the same for ewes and castrate males. There was no effect of the transgene on greasy wool production, mean fibre diameter or fibre curvature. Animals heterozygous for the transgene had significantly higher average coefficient of variation of fibre diameter than those without the transgene.

A 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...

The effect of a transgene encoding ovine growth hormone and regulated by a metallothionein promoter was examined in progeny of 69 Merino ewes and 49 Poll Dorset ewes that were inseminated by rams heterozygous for the gene construct. The presence of the transgene had no effect on the progeny from one of the three rams used, as evinced by a normal concentration and secretion pattern of growth hor...

To approach this ta...

Wool growth depends on hormones activity. Owing to hormonal status is extensively affected by surgical excision of endocrine glands, disease or severe congenital abnormalities, wool growth will be altered.

Insulin-like growth factor 1 receptor (IGF-1R) is a main receptor of IGFs family which plays a critical role in the postnatal growth and skeletal growth in many species. However, there are few reports of IGF-1R gene structure and its effects on growth traits in sheep. The objectives of this study were detection of IGF-1R polymorphisms and assessment of their associations with ...
