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...

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...

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 contribution of genetic and phenotypic parameters affecting fleece traits in 3/4th bred 2425 Bharat Merino Lambs sired by 154 rams over period of 1982-96 was evaluated. The year and season of shearing, sex of lamb, type of birth, age and weight of lamb contributed 8 to 42% of the phenotypic variability in the fleece traits. The least square means for the first and second six monthly greasy ...

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...

The developments in Norwegian sheep breeding since the early 1990s are reviewed. For the largest breeding population, the Norwegian White Sheep, results are presented for both genetic and phenotypic changes. Of the nine traits that make up the aggregate genotype, the largest gain per year, in per cent of the corresponding phenotypic average, was found for carcass grade (1.66%) and carcass weigh...

The objective of this study was to determine the genetic parameters of methane (CH4) emissions and their genetic correlations with key production traits. The trial measured the CH4 emissions, at 5-min intervals, from 1225 sheep placed in respiration chambers for 2 days, with repeat measurements 2 weeks later for another 2 days. They were fed in the chambers, based on live weight, a pelleted luc...

The production performance of ewes was assessed in a terminal crossbreeding experiment involving five Merino and Merino-type dam lines and two terminal crossbreeding sire breeds. Dam lines were SA Mutton Merino (SAMM), SAMM rams crossed to Merino ewes (SAMM cross), Dohne Merino, as well as specialist Merino lines selected for clean fleece weight (FW+) and for an increased reproduction (Rep+). D...
