Desempenho bioeconomico de suinos em crescimento e terminacao alimentados com racoes contendo farelo de coco
The objective of this study was to evaluate the performance of growing-finishing pigs fed coconut meal diets. 20 Large White * Landrace crossbred barrows with 19.72.9 and 89.25.8 kg initial and final body weights, respectively, were allotted to a completely randomized blocks design with 4 levels (0, 10, 20 or 30%) of coconut meal and 5 replications. Average daily weight gain, average daily feed intake and feed conversion ratio in the grower phase (65 to 107 days old) and grower-finisher phase (65 to 149 days old) were evaluated. Economic parameters evaluated were average gross income, average feed cost, gross margin and average return. The best results of average weight daily gain and average gross income in the grower phase were obtained with the level of 22.5% of coconut meal in the diet. In the grower-finisher phase, the average gross income in the total period indicates that it is possible to include 22.4% of coconut meal in diets for pigs raised with residual corn meal and soyabean meal.
