(Co)variance components and genetic parameters of weight at birth (BWT), weaning (3WT), 6, 9 and 12 months of age (6WT, 9WT and 12WT, respectively) and first greasy fleece weight (GFW) of Bharat Merino sheep, maintained at Central Sheep and Wool Research Institute, Avikanagar, Rajasthan, India, were estimated by restricted maximum likelihood, fitting six animal models with various combinations ...

Fifty-one yearling Angora doelings (20+/-0.6kg initial body weight (BW)) were used to determine effects of different dietary protein sources on BW change and mohair growth. Diets consisted of approximately 40% roughage and 18-19% CP (DM basis), of which two-thirds was supplied by corn gluten meal (CG), cottonseed meal (CT), hydrolyzed feather meal (FT) or menhaden fish meal (FI); DM intake was ...

The ability to maintain weight during adverse seasons is an important characteristic in mature ewes. Ewes that lose less weight will be in better condition at mating and throughout pregnancy resulting in higher fertility, fecundity and lamb survival, and lower ewe mortality. Liveweight data (corrected for greasy fleece and conceptus weights) from mature Merino ewes was analysed to determine fac...

this study was conducted to investigate the hair production and fleece characteristics of hairy goats according to the sex and age of animals. the material of the study consisted one total data of 73 hair goats, which were between more than one year-old and one year-old lori goats from both sexes (26 males and 47 females). the overall fleece weight, fiber length, lock length, washing yield, hai...

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...

In the present study, twenty-five male goat kids (20±2.5 kg BW) were used during an 84- day experimental period to determine the effect of source and level of sulfur supplementation on mohair characteristics and performance. Experimental diets were diets containing 0.18% (as control), 0.24% and 0.34% DM inorganic or organic sulfur. The data were analyzed as a 2 × 2 factorial design. Methionine ...

Data were recorded for annual reproduction, wool traits and pre-joining live weight of between 992 (for staple strength) to approximately 1200 production records of Merino ewes over the period from 1997 to 2002. The resource population has been divergently selected from the same base since 1986, either for (H line) or against (L line) maternal multiple rearing ability. When expressed relative t...
