Abstract

Objectives were to analyse absolute and relative size of mink at maturity, and to test effects of selection line, sex and interaction on size. For male and female mink selected for high or low feed efficiency, size at 30 weeks was analyzed for body weight, carcass weight, pelt weight, subcutaneous fat weight, and pelt length. For absolute size, an ANOVA model included effects of line, sex, and interaction. For relative size, two models were used: an allometric model and an extended allometric model, which included effects of line, sex, and interaction. For the ANOVA model, sexes differed for each variable; females were less than males. As a percentage of body weight, however, carcass weight was larger in females than males, whereas fat weight was smaller in females than males. For the extended allometric growth model, sexes differed for carcass weight and subcutaneous fat weight; females fattened faster than males.
