Influence of a mink genotype on their reproductive and productive traits

Abstract

During researches it was determined that the mink genotype affects their reproductive traits. Minks silvery-blue appeared less on 7,29 %, 73,42 and 6,95 %, than at animal genotypes “wild”, pastel and standard dark brown quantity of cover to males, shorter pregnancy period(on 0,8; 1,4 and 1,0 days) and higher (on 0,19, 0,39 and 0,2 animals) multiple pregnancy. Minks of coat color standard darkly brown were characterized by the greatest size of hide. On the average area of hide males surpassed age analogues of genotypes wild, pastel and silvery-blue on 0,2; 0,1 and 1,0 dm3, and female - on 0,4 and 0,8 dm3. The best profitability of manufacture of hide appeared with mink of color standard darkly brown and silvery-blue. It has made 43,89 and 40,33 % accordingly. It is offered to rear minks with coat of color standard darkly brown and silvery-blue coloring that allows to receive furs of high quality at higher profitability of its manufacture.
