- ÍtemInfluencia de proteasas y carbohidrasas en la alimentación de pollos de engorde. Aplicación de diseño de experimentos(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Martín Rincón, Jenny Carolina; Fonseca Gómez, Lida RubielaTwo experiments were carried out where the fortification effect of food for broiler chickens was evaluated by means of adding two different types of enzymes (four proteases in the first experiment, and six carbohydrases in the second one). This was done with the purpose of determining their impact on growth performance indicators, such as: body weight, feed intake and feed conversion ratio. The data were collected by using a completely randomized design on days 1, 7, 21 and 35. It was observed that the addition of proteases did not show any effect on day 7, but the treatments evidenced significant differences in body weight and feed conversion ratio (P≤0.05) on day 21. Nevertheless, these differences did not keep their tendency by the end of the experiment (day 35). On the other hand, the treatments where carbohydrases were added showed significant statistical differences from day 21 until day 35, where the results indicated that body weight and feed conversion ratio were improved by adding the carbohydrases from treatment 8, compared to the results obtained in the control treatment. As a conclusion, birds had a positive response to the addition of carbohydrases from treatment 8. However, it was not possible to choose any protease since they had no effect on the evaluated growth performance indicators.
