Growth hormone (GH) has an effect on a broad variety of physiological parameters such as lactation, reproduction, growth and metabolism. Thus, the aim of this study was to detect GH gene polymorphism and its association with breeding values of production and reproduction traits in Raini Cashmere goat. Breeding values were estimated using records on 26731 Raini Cashmere goats. To study GH gene p...

Twenty Naieni breed replacement ewe lambs were used to determine the substitution effects of treated wheat straw with exogenous fiber-degrading enzymes for alfalfa hay on wool characteristics. Five treatment diets were included: 1) control (100% alfalfa hay without wheat straw), 2) 10% enzyme treated wheat straw replaced for alfalfa hay, 3) 20% enzyme treated wheat straw replaced for alfalfa ha...

Using pedigree and performance records obtained from two Merino breeders the phenotypic and genetic relationship between subjectively assessed sheep and wool traits and objectively measured wool traits were estimated. The subjective traits were all favourably genetically correlated with fibre diameter. The genetic relationship with body weight, greasy fleece weight and fibre diameter variation ...

Blocks containing urea were provided to groups of penned sheep fed ad libitum on roughage of either 2.3 % or 5.1 % crude protein content and the results were compared with unsupplemented groups. One block contained 7.1% urea with finely ground sorghum, distillers solubles, common salt and rock phosphate. The other block contained 30.070 urea with common salt, rock phosphate, molasses and pollar...

The fibre characteristics of fleece determine its fate through the textile industry. Parameters such as diameter, length, elasticity and strength define functional quality fleece. Therefore, aim present study was to investigate effects different environmental factors well wool mineral contents on traits in Central Anatolian Merino sheep. Additionally, were investigated. For this purpose, 300 sa...

Forty female Angora goats were selected at random from the experimental nucleus of the National Institute of Agricultural Technology (Pilcaniyeu, Argentina), with the aim of analyzing the variability of main fleece characteristics of the Angora goats and establishing an optimum sampling site. Samples were taken at the first and second shearings (12 and 18 months of age) from the following parts...

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...

Abstract Polymer coatings on cellulosic fibres are widely used to enhance the natural fibre properties by improving, for example, hydrophobicity and wet strength. Here, we investigate effects of a terpolymer P(S-co-MABP-co-PyMA) coating cotton linters eucalyptus improve resistance cellulose against wetness. Coated uncoated were characterised using scanning electron microscopy, contact angle mea...
