title: The effect of colistin feeding during the mating, gestation and lactation periods on whelping result in mink.
abstract: Colistin (100000 IU/kg) was given in the feed during the mating, gestation and lactation periods to 49 female standard minks. 99 similar animals served as control without the antibiotic. The whelping result, expressed as the number of puppies living three weeks post partum per mated female, was 3.22 in the experimental group and 2.67 in the control group. The difference in the whelping result between the groups was mainly due to the significantly greater number of empty females in the control group compared to the experimental group.
