| Abstract | The experiment was conducted to determine the effect of increased levels of dried coconut meal supplemented with anenzyme cocktail? on diet utilization in growing pigs. A 4x4 latin square design was used in this study. Four crossbred (Durocx Landrace x Large White) barrows averaging 17.88?0.96 kg in body weight were allotted 4 diets, diet 1 (the control diet),diet 2, diet 3 and diet 4 (5, 10 and 15% dried coconut meal in each diet with an enzyme cocktail?, 1 kg of the enzyme cocktailcontaining the activities of phytase 1,000,000 units, amylase 5,000,000 units, xylanase 3,500,000 units, beta-glucanase2,000,000 units, cellulase 1,500,000 units, pectinase 1,000,000 units and mannanase 800,000 units; 500 g/t of feed, at a level0.05% in the diets, respectively). Pigs were raised in individual metabolism cages. Faeces and urine samples were collected4 times a day for 5 days for data collection. The results showed that the nutrient digestibility percentage of dry matter, crudeprotein, crude fat, ash, nitrogen-free extract, blood urea nitrogen, digestible energy (kcal/kg) and metabolizable energy (kcal/kg) were not significantly different (P>0.05) in pigs fed with different diets. However, pigs fed with 5, 10 and 15% driedcoconut meal in the diet with an enzyme cocktail? at a level 0.05% had significantly (P<0.05) higher digestible fiber than pigsfed with the control diet, and increased (linear and quadratic contrast, P<0.05). Pigs fed with the control diet (diet1) hadsignificantly (P<0.05) higher digestible apparent biological value than pigs fed with 15% dried coconut meal in a diet with anenzyme cocktail? at a level 0.05% but not significantly different (P>0.05) from the other groups. Apparent biological valuescontrarily reduced (linear and quadratic, P<0.05) with increasing level of dried coconut meal in pig diets. In conclusion,our data indicate that pigs fed with 5% dried coconut meal in a diet with addition of an enzyme cocktail at a level of 0.05%can show obviously increasing the highest digestibility of crude fiber (79.25%) without impairing nutrient digestibility |
