Growth, Development and Natural Resistance Indices of Replacement Calves of Belarusian Black-motley Breed Depending on Presence of BLAD Mutation
Abstract
Growth, development and natural resistance indices of replacement calves of Belarusian Black-motley breed of 6 months of age depending on presence of BLAD mutation were studied at Enterprise “Orshanskoe pedigree plant” in Vitebsk region. The lower indices of live weight and average daily weight gain were registered with animals with BLAD-syndrome. The increase of leucocytes quantity (up to 14,5 109/l) as well as decrease of aspartate aminotransferase activity in blood serum at 19,5 % was determined in the group with heterozygous calves compared to healthy animals.
