Efeitos do mananoligossacarídeo (MOS) sobre o desempenho de suínos na fase de crescimento

Abstract

The use of efficiency enhancers such as prebiotics in diets is increasingly common in pig farming, and makesit possible to produce meat within the concept of clean production, in other words, without usinggrowth promoting antimicrobials, which have been banned in many places around the world, especially in the countries of the European Union. Given the above, the objective of this work was to evaluate the effects of mananoligosaccharide (MOS) on weight gain variables, feed intake, food conversion,and the cost of feed per kg of animal produced from pigs in the growing phase.A completely randomized design was used, with two treatments (T1 - Control Treatment and T2 - MOS Treatment), three repetitions and two animals per experimental unit, totaling 12 animals. Performance data were subjected to analysis of variance, with the difference between the averages verified by the F. test, there was no effect(P>0,10) of CR treatments. While animals fed prebiotic-containing feed.While animals fed with prebiotic-containing feed (treatment 2) showed better results in CA and GP (P<0,10), when compared with treatment 1. Under the conditions in which this study was conducted, it can be concluded that the use of MOS improved the productive performance of pigs, but it was economically unfeasible.
