| Summary: | (6.45 [] 0.12) were randomly assigned to receive either a (P<,O.Ol) follicles as well as the size of the largest 29 days after calving), while large follicles L> 8.0 mm) 3.74 % EE) supplement after calving. The experimental diets abnormal estrous cycle length continued to be bled until a breedings of the cows continued until the first detectable calves nursed by fat supplemented cows possibly due to a concentrations were not influenced (P>0.10) by treatment. conclusion, using dm bran as a fat supplement for multiparous cycles had resumed. The intervals from parturition to days 1 to 43 after birth and at weaning (205 days). Fat Dietary fat also increased body condition scores, pregnancy dietary treatments as well as the percentage of cows showing estrous cycle to verify the presence of a CL and register estrous cycle. Similar follicular populations (P>0.10) were estrus. Thereafter, daily blood samples were collected fat-added (rice bran, 5.18 % EE) or a no fat-added (control, fertile bull. Enhanced calf performance was observed in first normal estrous cycle was completed.
