RESUMO

The objective of this work was to study the use of integral babassu and its sub product (babassu meal), as an alternative energy source substituting part of corn on feeding of peccaries in captivity production systems. At the first phase of the work, experiment - I, the performance of 12 animals was evaluated where the integral babassu was tested as an alternative energy source to substitute the corn in maintenance diets. In the experiment - II, the performance of 12 animals was evaluated and the babassu meal was tested as an alternative energy source to substitute the corn in finishing phase diets and after that, the animals were slaughtered to analyze their carcasses and meat. The carcass characteristics were evaluated (dressing percentage, corporal composition, carcass measurements, organs and glands and commercial cuts). The slaughtered animals? ham meats were evaluated on their properties (cooking losses, shear force, pH and water holding capacity) and the fatty acids contents. The average daily gain and the average daily feed intake of the animals that received crescent levels of the integral babassu, decreased when the proportion of the integral babassu increased, but until the level of 25% of inclusion of integral babassu the animals on maintenance obtained a satisfactory feed intake. Considering the availability and low costs of the integral babassu in Amazônia beside the corn, it can suggests until the level of 25% of inclusion of integral babassu in peccaries maintenance diets. Although there were observed no significant differences (P>0.05) of the levels of babassu meal on the average daily gain and the average daily feed intake, the results suggested that the inclusion of 40% of babassu meal in the diet of peccaries in finishing phase obtaining satisfactory development of the animals. There were observed no significant differences (P>0.05) of the babassu meal levels to the variables live weight, fasting weight, hot carcass, cold carcass, length, blood, leather, hind and front feet, hot and cold dressing percentage and commercial cuts. There were a quadratic effect of the babassu meal to the organs and glands on the lung (P=0.01) and on the liver (P=0.04). There were observed no significant differences (P>0.05) of the babassu meal levels for the meat properties and the unsaturated fatty acids (mono and polyunsaturated) were found in more quantity than the saturated fatty acids on the ham meat of peccaries. It seems that there is a tendency for a larger daily weight gain, intake, good dressing percentage and weight of the commercial cuts at the diet until 40% of babassu meal, then it can recommend the same as an alternative energetic in substitution of corn in diets for peccaries in finishing phase. Comparing the peccary meat with the bovine one, ovine and swine meat, the unsaturated (mono and polyunsaturated) were higher than the saturated fatty acids on the peccary meat, based on the theory that the polyunsaturated fatty acids ingested on the human diet are responsible of one reduction of the seric levels of cholesterol, then it can suggest that the peccary meat is an excellent alternative source of protein.
