| Abstract |
This research evaluated the effects of biscuit bran and cashew nut bran as energy source and additional energy level on intake, digestibility, feeding behavior, energy partitioning, N balance, and blood parameters on ewes. Twenty Morada Nova cull ewes breed (average age of 3 years old and initial body weight of 30.1 +/- 3.56 kg) were distributed in a completely randomized design in a 2 x 2 factorial scheme of two energy sources (biscuit bran vs. cashew nut bran) and two levels of energy above 10% and 25% of the recommended energy requirements. The inclusion of cashew nut bran above 10% of the recommended energy promoted a lower crude protein (CP) and ethereal extract intake (P < 0.01) than cashew nut bran above 25% of the recommended energy. The interaction between energy source x energy level did not affect digestibility and energy partition on ewes (P > 0.05). The diet containing cashew nut bran above 10% of the recommended energy presented lower metabolizable energy intake and energy balance (P < 0.05). Regarding N balance, the cashew nut bran diet above 10% of the recommended energy decreased N-intake (P = 0.01), N-absorbed (P < 0.01), and N-balance (P = 0.04). Partial replacement of corn with the byproduct biscuit bran or cashew nut bran is a possible nutritional strategy. Ewes fed with 210 g/kg of biscuit bran presented greater CP intake and improvement of the protein use with the reduction of plasma levels of urea. |
