There are varieties of factors which can affect wool (macro and micro elements of wool) in sheep directly or indirectly. Genetic and environmental factors are major factors influencing wool quality and quantity. There are some bacterial, viral, fungal and espically parasitic diseases which also affect the wool. Other factors are exogenous chemicals, hormones, weather and photo period. In the pr...

Fiber diameter is a useful indicator of wool traits and it is the main determinant of wool quality and value. A comparative study was conducted to analyze the abundance and expression of 13 candidate genes using expression profile microarray analysis and to identify novel molecular markers associated with wool traits to provide a molecular basis for improving wool quality in sheep. Genes associ...

The textile industry uses different fibers obtained from various animals, of which the wool from domesticated sheep Ovis aries is commercially the most important. Dyeing is one of the most important finishing procedures of wool processing. It almost invariably involves absorption of water-soluble colorants from aqueous solutions by the fibers. Diffusion is the process by which the colorant mole...

Abstract A new class of sustainable building composite materials is developed, made out recycled fibers waste, sand from crushing inert waste and lime. The come abundant available bio-based or mineral such as cellulose, glass wool, rock wool. comes used instead river which a resource under shortage. Lime is, like the other two constituents, locally. targeted performance minimizing environmental...

Recently we reported elimination of radioactivity from [14C]heptachlor from body stores of lactating ovines, mainly into excreta rather than milk, contrasting sharply with bovines. To further assess heptachlor metabolism and clearance by ovines, 12 fine-wool wether larabs (41 + 3 kg) housed in metabolism stalls were fed pelleted alfalfa hay (96%) plus molasses (3%) ad libitum and were dosed i.p...

b) Numbers. The total sheep population in the Chokla distribution area was 0.53 m according to the 1972 census and 0.511 m according to the 1977 census, thus showing a slight decline. Of these, adult males and adult females were 0.049 and 0.352 m respectively. Chokla is perhaps the finest carpet-wool breed, although most Chokla wool is now being diverted to the worsted sector because of the dea...

Follistatin (FST) is involved in hair follicle morphogenesis. However, its effects on hair traits are not clear. This study was designed to investigate the effects of FST gene single nucleotide polymorphisms (SNP) on wool quality traits in Chinese Merino sheep (Junken Type). We performed gene expression analysis, SNP detection, and association analysis of FST gene with sheep wool quality traits...

Melatonin implants are commonly used to control sheep reproduction during the winter solstice, but their effect on wool growth is unclear. In this study, wool growth was measured in 17 Assaf (carpet wool), 21 Rasa Aragonesa (medium wool) and 20 Merino (fine wool) ewes after inserting melatonin implants in January, February and April, and 13 ewes were used as control. All ewes were previously ov...

Supply chain management is currently receiving much attention in the wool textile industry especially following recent wool industry enquiries in Australia and New Zealand that have highlighted the need for improved communication between processors and wool growers. Supply chain management is also seen as a way of improving on-farm innovation, which is currently low compared to other agricultur...
