| Popis: | The aim of this research was to evaluate the effect of the Mentha spicata L. infusion on the performance and organoleptic characteristics of Cobb 500 broilers. The management, biosecurity and welfare of birds for open houses systems were followed, using a completely random design (CRD). Were used 200 1-day-old mixed chickens, in order to evaluate treatments effects during 35 days. Those were distributed in five treatments, with four réplicas, of 10 birds each to the following the groups: T1 (control), T2 (M. spicata infusion at 10%), T3 (M. spicata infusion at 20%), T4 (M. spicata infusion at 30%) and T5 (M. spicata infusion at 40%). The variables studied were broilers performance, carcass weight and organoleptic characteristics. The data was processed using with the statistical program Statgraphics Centurión XV.I, performing a multivariate analysis of variance and determining the factors with effect, and an ANOVA per week for the productive variables; contingency tables were prepared with organoleptic indicators data to determine differences (Chi-square test). Results show that the administration of M. spicata L. to drinkable water has no effect on broilers performance, with the exception of the feed intake, which decreases, reflecting a similar effect on visceral weight. The presence of flavonoids in the plant diminished the thickness of the abdominal fat because it favors the lipid metabolism of the birds. There was no difference in the smell of the meat, however, there were significant differences in the parameters of flavor, tenderness and juiciness. |
