Estimates of (co)variance components and phenotypic and genetic parameters of growth traits and wool traits in Alpine Merino sheep.

Journal of Animal Breeding and Genetics, 2022
The (co)variance components and corresponding phenotypic and genetic parameters for growth traits and wool traits of economic importance were estimated in the Alpine Merino sheep population maintained at Gansu Provincial Sheep Breeding Technology ...

Variation in the ovine KRT34 promoter region affects wool traits

Small Ruminant Research, 2022
Abstract The hard α-keratins are the main component of wool fibre and are assembled in a highly organized fashion into the keratin intermediate filaments (KIFs). Variation in the keratins affects wool structure and fibre characteristics, and thus their genes make ideal candidates for the development of gene-markers. A total of 300 sheep were used for

Application of proteomics for determining protein markers for wool quality traits

Electrophoresis, 2000
The technique of two-dimensional electrophoresis (2-DE) has been under investigation for its usefulness in identifying protein markers for wool quality traits in sheep. However, before this could be achieved, unique problems relating to the detection and quantitation of wool proteins needed to be overcome so that 2-DE protein maps could be examined ...

Unravelling the proteome of wool: Towards markers of wool quality traits

Journal of Proteomics, 2012
With ongoing efforts to make wool more competitive alongside other fibres, notably synthetics, there is a need to obtain a better understanding of the relationship between protein composition and characteristic wool properties to assist sheep breeding programmes.

Genetic correlations between wool traits and meat quality traits in Merino sheep

Journal of Animal Science, 2017
Genetic correlations between 29 wool production and quality traits and 25 meat quality and nutritional value traits were estimated for Merino sheep from an Information Nucleus (IN). Genetic correlations among the meat quality and nutritional value traits are also reported. The IN comprised 8 flocks linked genetically and managed across a range of sheep

Identification of the KAP27-1 gene in sheep and its effect on wool traits

New Zealand Journal of Agricultural Research, 2022
The keratin-associated proteins (KAPs) are structural components of wool and hair fibres, with over 90 genes that encode these proteins having been identified in mammalian species.

Wool quantitative trait loci in Merino sheep

Small Ruminant Research, 2008
Abstract With the aim of identifying QTL affecting wool production and wool quality in Merino sheep, specific regions of chromosomes 3, 4, 11 and 25 were analyzed in eight half-sib families, with an average of 63 offspring per sire. Greasy fleece weight and body weight were recorded at hogget and adult shearing.

Correlation Analysis of Microsatellite DNA Markers with Wool Traits in Liangshan Semi-fine Wool Sheep

HEREDITAS, 2006
Eighteen microsatellites on chromosomes 1, 2, 3, 9 were studied to detect their genotypes in 206 individuals in a Liangshan Semi-fine Wool Sheep nucleus breeding population. A GLM procedure was used to analyze the effects of these 18 microsatellites on wool traits. Results uncovered 7 loci that had a significant impact on wool traits. Genotypes of that

Two-Stage Machine Learning-Based GWAS for Wool Traits in Central Anatolian Merino Sheep

Agriculture
Wool traits such as fiber diameter, fiber length, and greasy fleece yield are economically significant characteristics in sheep breeding programs. Traditional genome-wide association studies (GWAS) have identified relevant genomic regions but often fail ...

Genetic parameters for wool traits, live weight, and ultrasound carcass traits in Merino sheep

Journal of Animal Science, 2017
Genetic correlations between 29 wool production and quality traits and live weight and ultrasound fat depth (FAT) and eye muscle depth (EMD) traits were estimated from the Information Nucleus (IN). The IN comprised 8 genetically linked flocks managed across a range of Australian sheep production environments.
