A study of some wool traits in two coarse wool breeds and their reciprocal crosses
The Journal of Agricultural Science, 1978SummaryIn a study of two coarse wool breeds (Awassi and Karadi) and their reciprocal crosses, data were obtained on the mean fibre length, mean fibre diameter, fibre type ratio, medullation and on the effect of some environmental factors on these traits. Reciprocal crosses showed intermediate values, in growth rate of fibres, percentages of fibre types

Application of proteomics for determining protein markers for wool quality traits
Electrophoresis, 2000The 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 ...

Wool quantitative trait loci in Merino sheep
Small Ruminant Research, 2008Abstract 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.

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

Genetic parameters for wool traits, live weight, and ultrasound carcass traits in Merino sheep
Journal of Animal Science, 2017Genetic 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.

The study of variability in some wool traits in a coarse wool breed of sheep
The Journal of Agricultural Science, 1973SummaryWool samples from 47 Barki yearlings were taken from five positions during two years to study the variability in the fleece, the cause of variability and associations between different fleece traits. Statistical analysis has indicated the following significant points.An antero-posterior gradient occurred in the different traits under study. When

Relative economic importance of some wool quality traits for Merino and crossbred wool types
Australian Journal of Experimental Agriculture and Animal Husbandry, 1970The economic weights of various quality traits of both Merino and crossbred wool types hive been estimated. Australian averages of clean wool prices for Australian Wool Board wool types, into which mid-side samples of fleece were classified, have been used.For each of fifteen seasons, 1953-54 to 1967-68, the mean clean wool price for each wool type was

Animal Production Science, 2009
The aim of this paper was to describe the genetic relationship among expressions at different ages of seven wool traits: greasy and clean fleece weights, fibre diameter, coefficient of variation of fibre diameter, staple length and strength, and mean fibre curvature.

Wool traits of three sympatric sheep populations in Chiapas Region, México
Tropical Animal Health and Production, 2012A total of 344 pure animals, representing seven American and South European breeds (White Chiapas Blanca, Brown Chiapas Café, Black Chiapas Negra, Churra Badana, Churra da Terra Quente, Chilean Latxa, and Spanish Merino), were randomly sampled and wool evaluated for isoalcohol scouring yield, length, and proportion for each type of fiber (long-thick ...

Heritability estimates of wool follicle traits in sheep skin
Animal Science, 1984ABSTRACTData were collected from 600 newborn lambs, offspring of 354 Western crossbred ewes and 26 rams, to determine heritability estimates as well as phenotypic and genetic correlations between wool follicle variables using histological techniques. Breed of sire and sire within breed were significant sources of variation in total and secondary wool ...
