EFFECTS OF DIFFERENT LEVELS OF BABAÇU BRAN ON THE SWINE DIET

Abstract

Babassu meal has been used in family farming, despite its lack of nutritional value. Furthermore, it is necessary to carry out research to establish usage patterns and laboratory tests to determine their nutritional characteristics, in order to know their effects on the nutrition and growth of their pigs. In this context, or objective of this study, was to evaluate the nutritional value and/or zootechnical performance of growing pigs, fed with different levels of inclusion of babassu meal in the diet. The study was carried out at the Integrated Unit for Training, Research and Extension (UNIEPE) of the Swine Industry of the Federal Institute of Pará (IFPA) Rural campus of Marabá. Sixteen mixed pigs with an initial weight of 7.63 ± 1.31 kg were used, randomly distributed in four pens. The experimental design was internally randomized, with four treatments (0%, 10%, 20% and 30%) in four repetitions. Register by varying weight gain and nutritional value. Data are subjected to analysis of variance and polynomial regression at a 5% probability level. As a result, it appears that the nutritional composition of babassu bran is rich in dry matter (89.08%) and crude fiber (46.84%). In addition, the weight gain, two piglets, was influenced by the inclusion of babassu in the diet. This variable has a negative linear effect (P <0.05), with a coefficient of determination (r²) of 0.88. Therefore, it is possible to conclude that the addition of babassu meal linearly reduced the growth of piglets with the inclusion of up to 30% of the diet.
