Abstract

With the help of cytogenetic analysis in breeding herds of cattle found that most of the cows tested karyotype as normal, but in the third part of the cows found in the mutant cells and aberrant chromosome karyotype.

It was also found that in the investigated cows of herds from the Shchors pedigree plant the total percentage of mutative cells is 17,0 % and in cows of herds from «Agrosvit» this data is twice higher – 35,8 % (Р < 0,001). Low correlation was found between the number of cell mutation and performance (r = 0,108–0,299, P > 0,05).

Cytogenetic indicators characterize chromosomal status of animals and is a marker of the intensity of metabolism in animals that cause an increase in milk yield of cows. Evaluation kariotypovoyi variability of breeding stock will help in the short term to detect and remove carriers a high level of chromosomal disorders.
