Farelo de palma gigante com adição de enzimas exógenas na nutrição de suínos em crescimento

Abstract

The research was developed to evaluate the digestibility of gross energy from giant palm bran, the performance of growing pigs, organ weights and the economic viability of diets composed of different levels of inclusion of giant cactus meal, with and without addition of enzyme complex (EC). In the digestibility analysis, ten castrated male swine with an average weight of 34.3 ± 6.35kg were used. Five of them were fed with a reference feed, and the five others received a feed testing, with 30% of substitution of a reference diet by giant palm bran, for a period of fifteen days. In this period, the total feces collection was made daily (8am) without a label use, being withdrawn at a rate of 20% and stored in freezer. In the performance test, twenty females swine were used, they were distributed in randomized blocks design with five treatments and four replications. The treatments consisted of inclusion of levels of giant palm bran, associated with the enzyme complex, following a distribution: 0%; 5%; 10%; 5% + EC; 10% + EC, where treatments with EC addition had a deficit of 100 kcal / kg in the diets. The value of the gross digestible energy of giant palm bran for pigs in the growth phase was 1113.83 kcal / kg. It was observed that the weight gain and the absolute weight of the organs of pigs were not affected by the diets. However, feed conversion, feed intake and relative weight of the organs showed alterations (P <0.05) using the Duncan test. It was also found that the inclusion of the enzyme complex associated with giant palm bran supplied the deficit of 100 kcal / kg once the weight gain and feed conversion were in accordance with the nutritional requirement of Rostagno’s tables et al. (2005).
