Studying on the variation trend of life weight and wool productivity in Synthetic population Bulgarian milk sheep raised in Institute of agriculture Karnobat
Margarit Iliev, Todor Tsonev
Abstract: The aim of the study was to identify and analyze the phenotypic variations in the live weight and wool productivity of sheep from the Synthetic Population Bulgarian Milk breeding in the herd of the Karnobat Institute of Agriculture. The subject of the study was 524 animals born in 2006–2011. The magnitude of signs was found: live weights at 1.5, 2.5, 3.5 and 4.5 years, wool productivity at 1.5, 2.5, 3.5 and 4.5 years, wool yield and clean wool 1.5 years of sheep. A credibly higher live weight for the studied ages for the animals born in 2006 and 2008 (excluding weaning weight) was found, and in 2010 and 2011 it is significantly lower. Wave production is significantly higher in 2009 at 1.5 and 2.5 years old, in 2008 at 3.5 years and in 2007 at 4.5 years, and in 2011 it is credibly lower to 1.5 years and in 2010 to 2.5, 3.5 and 4.5 years. It was found that the animals of the herd studied had normal physiological status, allowing the realization of their genetic traits for good productivity. The live weight increases, but wool productivity variation is insignificant with age. The level of these two productive traits corresponds to the selection limits of tribal dairy sheep. In the different individual years, the specificity of nongenetic factors influences their productivity.
