Fresh and stored copra meal in meat quail diets
The aim of the current study was to evaluate the addition of fresh and stored copra meal to the diet of meat quails. Two hundred eighty-seven-day-old male and female quails were distributed in a completely randomized design, with five treatments, in a 2 × 2 + 1factorial arrangement. Two copra meal types (fresh and stored) at inclusion levels of 12.5% and 25%, respectively, were added to a corn-soybean meal-based diet, with seven replicates, of eight quails each. Copra meal acidity index recorded oleic acid percentage increase from 0.47 to 3.03% after six storage months. However, regardless of storage type, its addition to quails’ diet resulted in higher values of metabolizable energy, in lower feed intake and better feed conversion than corn-soybean meal diet. Copra meal addition to quails’ diet did not affect carcass traits, liver and pancreas relative weight, and bone growth and quality. Although copra meal storage for 180 days resulted in higher free fatty acid content in the provided feed, it can be used fresh or after storage, in diet of meat quails from 7 to 42 days of age up to 25%.
