Productive characteristics in broilers using oregano flour as a growth promoter

In order to evaluate the inclusion of proportions of oregano leaf flour (HHO) in the commercial balanced feed (ABC) of broilers, the body weight (CP), daily gain were quantified in the start and fattening phase weight (GDP), daily feed intake (ADC), feed conversion index (ICA) and mortality (OM) in a completely randomized experimental design. 208 chicks of the Ross line were used distributed in four treatments: ABC100%: 100% balanced feed; ABC + 0.25HHO: Balanced feed + 0.25% oregano flour; ABC + 0.50HHO: Balanced feed + 0.50% oregano flour and ABC + 0.75HHO: Balanced feed + 0.75% oregano flour, with four repetitions and 13 birds per experimental unit. The variables PC and GDP were analyzed by regression, while CDA, ICA and MO were compared by descriptive statistics. The CP achieved significant differences at the end of the start-up and fattening phases, being the treatment ABC + 0.25HHO, the one that obtained the best result (773.18 and 2196.11g, respectively). The GDP followed the same trend as the PC, where the treatment ABC + 0.25HHO showed the highest value, with 35.01 and 67.71g at 21 and 42 days, respectively. The variables CDA and ICA were favored with the ABC + 0.25HHO diet. No statistical differences were found for mortality. The addition of 0.25% oregano leaf flour (HHO), as a phytogenic additive in the diet of broilers, had a positive effect on body weight, daily weight gain, feed consumption and feed conversion during the starting and fattening phase.
