The experiment was carried out to evaluate the effects of the replacement of corn silage by up to 100% sugar cane in diets for milking cows. Studied characteristics were milk production and composition, body weight variation, intake of nutrients and economical viability of the diets. Twelve pure and crossbred Holstein milking cows, with potential yield of 5,000 to 7,000 kg of milk per lactation, were distributed in three 4×4 balanced latin square. The animals were maintained in individual stalls, where […]

The present study evaluated the effects of alternating food restriction and refeeding cycles on the growth of pacu, during the growout phase and the viability of this practice in the commercial production of the species. Juvenile fish were distributed in 3 tanks and submitted to different feeding strategies: group A (fed ad libitum daily), B (food restricted to 4 weeks and refed for 9 weeks) and C (food restricted to 6 weeks and refed for 7 weeks) totalizing 13 weeks […]
