Evaluation of genome stability, haematological and productivity performance of young mink when using dried palm fat

Abstract

The article presents of the results on estimation genome stability, haematological and productive indices of young heads standard short-haired black mink, bred for pelts, when using in a diet supplement of dry palm fat during the period winter hair of formation (October-November). The control group of mink received a general farm diet without the additive. The palm fat additive was added to the feed mixture of the experimental group in an average amount of 0.75 g per 100 g of the feed mixture per day. It was found out that the composition the minks of the leukoformulas studied was within the physiological norm. Since four months of age, the young mink had a stable neutrophilic blood profile. Determination of the erythrocytes frequency containing micronuclei in the peripheral blood of young mink allowed to evaluate the stability (instability) of the genome during the introduction of dry palm fat to the diet. It was found that elevated frequency of erythrocytes containing micronuclei in the blood of males at the age of 7 months above the level of 7.7±1.84‰ (ppm) is connected with changes of diet composition and correlates with increase of live weight gain at conservation of morphophysiological characters and directed for realization of youngsters productivity - increase of area and good quality of skins.
