ABSTRACT
This work investigated the influence of adiposity on pregnant Crioulo mares on the weight and fat deposition of their foals from birth to four months of life. Twenty-eight Crioulo mares were evaluated during the final third of gestation, divided into two groups (normal and obese) regarding weight, neck circumference, neck crest height and fat at the tail base, and the relation of these measurements with those of their foals from birth to 120 days old. The obese mares presented higher fat deposition at the tail base in the 2nd month (P< 0.05) and crest of the neck (P= 0.0022) in the 4th month of age. There was positive correlation between height of mare's neck crest and foal weight at birth (P= 0.01, r= 0.54) and body weight of mares between the fat at tail base of foals at birth (P= 0.03, r= 0.49), as well as strong association between fat at the tail base in obese mares with this measurement in their foals at 4 months (P= 0.01, r= 0.71). This difference of adiposity between groups suggests that obese mare’s offspring are more likely to accumulate more fat in the first months of life.
