Evaluación de diferentes niveles de propóleo sobre los parámetros productivos en pollos COBB 500.

Abstract

The research evaluated different levels of propolis on the productive parameters in Cobb 500 chickens. In addition, the production costs of each of the treatments under study were analyzed. 192 Cobb 500 chickens were part of the experiment which were divided into 16 cages and by means of a completely random design the treatments: T0 or control treatment (0 ml of propolis / week), T1 (20 ml of propolis / week), T2 (25 ml of propolis / week) and T3 (30 ml of propolis / week) were assigned. Each treatment had 4 repetitions with 12 experimental units respectively. The delivery of the treatments was in the drinking water of the experimental units at 5 am during the days that the experiment lasted. Highly significant differences less than (0.01) were recorded in the total weight at 48 days of the investigation where the best registered weight corresponded to T3 with a weight of 3314.68 g. In addition to the variable weight gain from day 1 to 48, the T3 showed the best weight gain with 3271.18 g. The best total feed conversion also corresponded to T3 with 1.55. Similarly, there were significant differences lower than (0.05) in the yield variable where the best carcass yield corresponded to T3 with 73.94%. The same treatment had the best benefit with 1.17 USD. It is concluded that T3 (30 ml of propolis / week) in the drinking water, significantly, improves the productive performance in terms of final weight, weight gain, feed conversion, carcass performance and in the economic analysis where there was a greater benefit / cost compared to other treatments. Therefore, it is recommended to conduct research on the productive performance of Cobb 500 chickens with the supplementation of higher levels of propolis.
