Mananoligossacarídeo (MOS) na alimentação de leitões na fase inicial

Abstract

The use of efficiency improvers such as prebiotics in diets are commonly used in piglet farming, making it possible to produce meat within the concept of clean production, without the use of growth promoting antibiotics, which have been banned in several parts of the world, mainly in European countries. In view of the above, this study aimed to evaluate weight gain, feed intake, feed conversion and perform an economic analysis on the use of mannan oligosaccharide (MOS) as an additive in piglet feeding in the initial phase. For this research, 12 animals were used, male and female, distributed in a completely randomized design, with two treatments: T1- Basal ration without prebiotic inclusion and T2- Basal ration + 0.2% prebiotic, with three replications and two animals per experimental unit. The performance data were submitted to analysis of variance, and the difference between the means was verified by the F test. There was no effect of treatments (P>0.10) for any of the parameters evaluated. Thus, it can be concluded that the use of MOS did not improve the productive and economic performance of piglets in the initial phase.
