Evaluación del efecto de tres diferentes forrajes: ramio (boehmeria nivea), botón de oro ( tithonia diversifolia) y yatago (trichanthera gigantea ) en una dieta comercial para pollos de engorde de la línea coob 2.

Abstract

The aim of the present work was to evaluate the effect on the production of broiler chicken of the inclusion of three different forage plants to a commercial concentrated diet, Agrinal® brand; in order to compare the impact on the zootechnical parameters (feed consumption, body weight, feed conversion, weight gain, food efficiency and economic profitability) of the groups evaluated. The population (100 male chickens of the Coob2 line) were randomly distributed in four groups fed during 44 days in the following way: group 1 (control), received only commercial feed of the Agrinal® brand during the experimentation period; groups 2,3 and 4 received the same diet as the control group until day 21 of experimentation; After that, they were given 20% less concentrated feed and this shortfall was covered with the ad libitum supply of Ramio (Boehmeria nívea), Yatago (Trichanthera gigantea); and Botón de oro (Tithonia diversifolia); respectively. The animals were kept in the same environmental and management conditions. The data were analyzed through analysis of variance using the Statistix 10 program; the level of significance required was P <0.05. The averages compared by the Tukey test. The economic analysis was carried out by calculating the cost benefit ratio. After the study, no significant differences were found in the parameters: body weight and feed conversion between the study groups, but yes, greater profitability in those treated with Ramio and Yatago.
