Ítem Acceso Abierto Papa china como alternativa de remplazo energético parcial en la ración alimenticia de pollos broiler.(Universidad Católica de Cuenca., 2022) Barros Guichay , Jhon Moises; Verdugo Piña , Pablo Sebastián; Cuenca Condoy, Mercy del Cisne; 0107127037; 0107265365The study evaluated the addition of Chinese potato (Colocasia esculenta), as a partial energy replacement in broiler chickens, on the effective response and in vivo digestibility. A total of 800 one-day-old broilers were used, distributed in 4 treatments, eight replicates and 25 broilers per replicate. Treatments included the control group (T0), the inclusion of Chinese potato meal in the feed ration T1 (10%), T2 (15%) and T3 (20%). The zootechnical management of the birds was similar in all treatments, with 49 days. The variables studied were: productive parameters, feed digestibility and cost-benefit ratio. The results showed that feed intake, weight gain, feed conversion and mortality percentage evidenced significant difference (p<0.05) during the growth phase, reaching the highest weight gain in T3 with 506.94 g. The best feed conversion was recorded in T2 with 1.34, the digestibility of DM and PB of feed was more edible in T0, and the fat content of the meal was more digestible in T1 and T3 during the growth and fattening phases, respectively. Hematological parameters did not show significant variation (p>0.05) between procedures and phases analyzed. The cost-benefit ratio was higher with T3, obtaining 0.70 cents/bird concerning T0, which showed a cost-benefit ratio of 0.49 cents/bird. It is concluded that supplementation with Chinese potato in broiler chickens' feed is an alternative for partial energy replacement. Keywords: Colocasia esculenta, production parameters, broiler chickens.
