Efeitos do orégano sobre o desempenho de suínos na fase de crescimento

Abstract

O regano has two components that are fundamental natural phenols in antimicrobial action and with potentialefficiency enhancing function, carvacrol and thymol. As such, it is a potential replacement for growth promoting antibiotics, as it ensures a healthy, waste-free end product without risk to consumer health. Given the above, the objective of this work was to evaluate the effects of oregano on the productive and economic performance of pigs in the growing phase. The experiment was carried out at the Pig Farming Teaching and Research Unit of the Federal Technological University of Paraná at the Dois Vizinhos Campus. Twelve male and female crossbred animals, 63 days old and initial weight of 23 kg were used. The experimental design was completely randomized, with two treatments: T1-Basal diet and T2-Basal diet + 0.4% oregano, with 3 replications and 2 animalsper experimental unit. The parameters evaluated were weight gain, feed intake, feed conversion and feed cost per kg of swine produced. Performance data were subjected to analysis of variance, with the difference between the means verified by the F test. There was no effect of treatments (P>0.10) for any of the evaluated productive parameters. While the worst economic result was obtained by T2 (with additive). It can be concluded that the addition of oregano powder in the growing pig diet did not positively influence the productive performance and was economically unfeasible.
