Resumo
The aim of this research was to evaluate diets with and without inclusion of propolis ethanolic extract Verde Alecrim on dry matter intake, metabolic profile and its relationships of reproductive aspects and to compare metabolic profile values with reference values established on the scientific literature. Treatments were: Control (CT), control diet; Flushing (FT), control diet plus 300 g/animal/day of corn meal; Flushing with level 1 of propolis (FTP1), FT plus 8 mL/animal/day of propolis ethanolic extract; Flushing plus level 2 of propolis (FTP2), FT plus 12 mL/animal/day of propolis ethanolic extract. Sixteen Santa Inês nulliparous ewes, empty, four per treatment, were assigned in a complete randomized design, in a factorial scheme and subjected to an estrus synchronization protocol and covered. The females were housed and the experiment consisted of an adjustment period of ten days, followed by an experimental period of 30 days (15 days for pre-mating and 15 days for post mating). Animals were fed twice a day at 7 AM and 4 PM. To determine the hematobiochemical profile, blood samples were collected at each five days in fasting and two hours after during 15 days in the pre-mating phase and 15 days in the post mating to estimate urea, total protein, albumin, globulins and AST enzyme contents. Ultrasound to confirm pregnancy thirty days following mating was used. It was found that treatment with lower concentrations of propolis ethanol extract Verde Alecrim presented the potential to decrease DM intake intake and that the ethanol extract of propolis has proved effective in decreasing the dry matter intake and concentration of serum urea. The CT, FT and FP1T provided the same pregnancy rate, superior to TFP2, however FP1T resulted in higher rate of twin births. Treatments with a lower concentration of propolis reduced urea content in serum in fasting and two hours after feeding and in the post-mating phase. Most of metabolite contents were within reference values, according to the literature
