To evaluate the effect of a hiperlipidemic diet on the reproductive performance, lipidic metabolites and serum progesterone levels, 42 Holstein-Zebu crossbred cows were submitted to two treatments: T1 (n=21), control diet, and T2 (n=21), hyperlipidemic diet, consisting mainly on whole soybean. The mean intervals to the first and second postpartum ovulations were 26.3 and 35.9 days for animals of T1 and 21.7 and 37.4 days for those of T2. The average intervals from calving to onset of the luteal activity, […]
