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

Variation in the ovine KRT34 promoter region affects wool traits
Small Ruminant Research, 2022Abstract 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

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 ...

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

The potential for the reduction of wool yellowing susceptibility (YPC) in Corriedale sheep via selection was examined. The heritabilities of YPC and greasy fleece weight (GFW) and clean fleece weight (CFW), yield percentage (Yield), mean fibre diameter (MFD), and subjective greasy wool colour assessment (Visual), and phenotypic and genetic correlations

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 ...

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 ...

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.

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

Associativity of selected traits in Aginskaya semicoarse wool sheep
Russian Agricultural Sciences, 2016Research findings in the phenotypic correlations of the live weight to the body measurements and the body conformation indices in the replacement young stock of the semicoarse wool sheep of the Aginskaya breed have been reported. It is ascertained that males surpass the females in the live weight and the body measurements.
