| dc.description.abstract | In Tungurahua province, Píllaro Canton, in San Miguelito parish, San Pedro de Cruzñan neighbor, the effect of extract Aloisya triphylla (kidron) at 2, 4, and 6% in drinking water in the production of broilers was evaluated comparing with a control treatment with 5 repetitions (TYR 10 chickens) giving a total of 200 chickens, distributed under a completely randomized design, for 49 days. The experimental results were subject to analysis of variance (ANOVA) and mean separation by Duncan (p-0.05 and p.0.01). The results showed and excellent performance with the addition of 6% (T3) verbena extract in drinking water in relation to other treatments, so that a final weight of 2331, 33 was achieved – 59, 57 g, weight gain from 46, 65 to 1, 21 g /day; FCR of 1, 93; the total feed intake was 4402, 00 to 16,82 g / bird with a marked reduction in mortality. In the same treatment (T3) nutrient intake was efficient and crude protein 15,37 g/ day; 201,68 metabolizable energy of Kcal day; water consumption 0,21 L/ day; As for the health of the chickens it was recorded that the parasite load was zero with 6% of extract with 97,5% (gram positive). In addition, the increased profitability is obtained, establishing an index of benefit/ cost $ 1, 19, which means a yield of 19%. For these preliminary results we recommend using this level of lemon verbena extract, since it increases the production parameters and improves the health of the chickens. | |
