AGE AT FIRST GESTATION IN BEEF HEIFERS AFFECTS FETAL AND POSTNATAL GROWTH, GLUCOSE METABOLISM AND IGF1 CONCENTRATION

Age at First Gestation in Beef Heifers Affects Fetal and Postnatal Growth, Glucose Metabolism and IGF1 Concentration

This study aimed to determine the effects of age at first gestation on offspring growth performance, glucose metabolism, and IGF1 concentration.Heifers impregnated by AI from a single bull at 15 months of age (15 M, n = 20), or 27 months of age (27 M, n = 20), and multiparous cows (adult, n = 20) were used.Dams from all groups were managed in a sin
