Evaluación productiva de pollos broiler (Cobb 500) alimentados con diferentes niveles de harina de hoja de yuca (Manihot esculenta) en la provincia de Morona Santiago.

Abstract

This study aims to investigate about the production efficiency of Broiler chicken line Cobb 500, at the early stage, gowth and fattening, fed with different percentages of cassava leaf flour (Manihot esculenta). Various criteria were assessed in terms of food consumption, weight gain, feed conversion, carcass yield and economic analysis. This research was carried out in Sevilla Don Bosco parish, Morona district, province of Morona Santiago, through a randomized design, the statistical tool Infostat and the Tukey test at 0,05 significance, by using four treatments and four repetitions. The levels of inclusion of cassava leaf flour were about 0% (T0), 5% (T1), 10% (T2) and 15% (T3) in the balanced diet. 160 experimental units have been used as of the day one of a livebirth all 42 days long. The statistical study evinced significant differences (P<0,05) in the variable feed consumption in the early stage, gowth and fatting. T3 treatment got better values such as 1421,25 g, 23330 g and 1486,25 respectively; the variable related to weight gain, in the early stage, generated highly significant differences (P<0,05) standing out T0 with 265,06 gams; with reference to the gowth stage no significant differences were found (P> 0,05), however do exist differences in numerical median, standing out T2 with 542,03 gams; during the fattening stage significant differences have been found (P<0,05) prevailing T0 with 599,57 gams. T0 treatment provided 1,94 in the feed conversion index (P<0,05); the carcass yield reported highly significant differences (P<0,05) standing out T0 with 88,5 %; it was reported 1,88 % mortality rate with three deaths; T0 treatment recorded 1,06 in the economic analysis. In conclusion, the addition of cassava leaf flour is not productive in chickens. It is recommended to investigate about less additions to evince the productive behavior of such raw material.
