Abstract

In Guano county, Chimborazo province, the productive and sanitary behavior of broiler chicken was evaluated by effect of three levels of extract of Allium cepa (cebolla morada) Var. Red creole in the drinking water T1 (2%), T2( 4%) y T3 (6 %) and a control treatment (productive and sanitary conventional system), using 384 broiler chicken divided in two trials (192 chicken by replica), with four repetitions by treatment (T.U.E. of 12 chicken), the same that were distributed under a random design, evaluating different parameters during 130 days of study. The experimental results were processed with SPSS (2008) and Excel (2010), subjected to a variance analysis (ADEVA) and the Duncan test for the separation of measures at the level of significance of P ≤ 0,05 and P ≤ 0,01. Determining that with 4% of onion extract in the drinking water, the obtained results were higher when compared to the control treatment, because the birds showed the best values in final weights of 2890,56g, weight gaining of 65,37 g/day, feed conversion of 1,84; carcass yield of 73,99%. Also using T2 of percentage of intestinal parasite load was null. Likewise the reached economic profitability was of 25% in difference to the application of the conventional sanitary system that was a 23%, so it is recommended to use the onion extract in levels of 4% in the drinking water as alternative of breading broiler chicken.
