Wool handling is an important rural occupation where workers process 200 or more fleeces daily, separating them into various quality components. Loads and postures they experience carry substantial risk of low back pain (LBP). Although a formal skill training structure exists, interaction with loads and LBP is unknown. We examined whether skill and LBP influenced trunk postures and loads of 60 ...

I. The nutritive value of solubilized wool protein prepared by dissolving finely ground wool in sodium sulphide-sodium sulphite solution followed by precipitation with 40 % acetic acid has been tested by incorporating it into protein-free diets containing the amounts of vitamins and minerals required by weanling rats. 2. At the level of 10 % (w/w) of the diet, solubilized wool protein failed to...

the aim of this study was to analyze the polymorphisms existing in the 5´ flanking region, exonic, and some parts of the intronic regions as well as methylation analysis of the ednrb gene in cattle and goat. these regions were sequenced in three different breeds of cattle including sistani, golpayegani, and holstein and were compared with that of marghoz goat. the results identified that this g...

Data on the effect of various alkaline reagents on the physical and chemical properties of wool yarn are presented. When wool is treated with dilute sodiumhydroxide solutions, a rapid splitting off of a portion of the sulphur occurs. On continued treatment, the sulphur content of the residual wool approaches a constant value of about 1.8 percent. The results indicate that the alkaline treatment...

Wool fabrics were treated with keratin hydrolysate in isolated systems, in systems incorporating a cross-linking enzyme, and in systems with nanoparticle silver. The dimensions of wool fabric were controlled after keratin applications and the strength of bleached wool fabric was improved. Keratin applications imparted these improved properties when applied alone and when applied with the enzyme...

Purpose Australia is the largest supplier of high quality wool in the world. The environmental burden of sheep production must be shared between wool and meat. We examine different methods to handle these co-products and focus on proportional protein content as a basis for allocation, that is, protein mass allocation (PMA). This is the first comprehensive investigation applying PMA for calculat...

An investigation into the moisture content in the fleece of Merino sheep was commenced after proposing the hypothesis that moisture and relative humidity were required at the skin surface for the survival of the 1st instar larvae and the initiation of a strike. A method for drying wool was developed which created a minimal disturbance to its normal constituents. It was shown that, in dry weathe...

The presence of dark fibres in white wool results in reduced profits or in cost recovery claims by wool processors and in reduced confidence in wool as an apparel fibre, which ultimately means lower prices for greasy wool. The allowances set by fabric manufacturers for contaminants are extremely small, typically no more than 3 contaminant faults per garment or per running metre of fabric, while...

one hundred female markhoz goats (42±5 kg) were used to investigate the ‘male effect’ on estrous synchronization and reproductive characteristics of female goat during the breeding season. this was carried out in three separate experiments. in the first experiment, forty female goats were used in 4 groups with different distance from the male goats (i.e. source of pheromone secretion); a1 (1 me...
