BLOOD PLASMA PROGESTERONE LEVELS DO NOT CORRELATE WITH LITTER SIZE IN THE AMERICAN MINK (Neovison vison)
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2018, Vol 47, Issue 343
Abstract
The aim of the study was to test whether there is a relationship between the plasma concentration of progesterone in a given stage of pregnancy and the litter size at birth. The study was carried out on a mink farm located in western Poland. Blood samples for analyses were drawn from year-old White Hedlund (WH) females. Samples were collected from 30 females, first on 22 February, i.e. before the mating season, and on 12 April, from pregnant females, about 3 weeks before expected parturitions. Plasma progesterone levels revealed a high individual variability within the studied group of mink. No significant correlation was found between blood plasma progesterone in pregant females and the average litters size at birth.
