Evaluación la harina de hoja de yuca (Manihot esculenta) sobre la pigmentación e índices productivos en pollos de engorde

Abstract

The objective of this research was to evaluate different levels of integration of cassava leaf meal (0%, 2%, 4%, 6%), on productive indices such as feed conversion, weight gain, mortality, carcass yield, also determine the degree of pigmentation and the benefit/cost of each treatment; For this, a completely randomized design (DCA) was used, which had 4 treatments, of which one of them corresponded to the control, six repetitions per treatment and consisting of 10 experimental units for each repetition, making a total of 240. chickens used. The distribution of means was analyzed using Tukey's statistical test at 99% reliability. Three stages were evaluated, the first was the initial stage (1 - 8 days of age), the second was the development stage (9 - 28 days of age) and the last one was the finishing stage (29 - 45 days of age). It was determined that the best result corresponded to T1 with an inclusion level of 2% of M. esculenta flour, presenting the best results and significant differences in terms of final weight and weight gain. However, no significant differences were found in relation to feed conversion, carcass yield and pigmentation.
