Probióticos na alimentação de leitões na fase inicial

Abstract

The use of efficiency improvers such as probiotics in piglet feed makes it possible to breed without the use of growth-promoting antibiotics, which are banned or restricted in many countries in the world. In this way, promoting creation within the concept of clean production. The objective of this work was to evaluate the effects of the use of probiotics in piglets on the variables of weight gain (WG), feed consumption (CR), feed conversion (FC) and the cost of feed per kg of animal produced. In this research, a completely randomized design (DIC) was carried out with 2 treatments T1 (Basal diet without probiotics inclusion) and T2 (Basal diet + 0.2% probiotics inclusion) with 3 replications and 2 animals per experimental unit, totaling 12 animals, being 8 female e 4 male. The performance data were subjected to analysis of variance (ASSISTAT 7.5, 2008), with the difference between the means verified by the F test. There was an effect (P<0.05) of the treatments only for the CR, which was greater in T1 (control). While the best economic result was obtained in T2 (with probiotics). Under the conditions under which the present study was carried out, it can be concluded that the use of probiotics improved the economic performance of piglets in the initial phase.
