Contextualization: the cocoa shell is an agro-industrial waste with no commercial value. It is generated at the collection site of this fruit during its primary production and is normally abandoned in large piles that generate environmental problems. However, the cocoa shell has adequate nutritional properties that allow its use in animal feed.

Knowledge gap: there is a small amount of scientific evidence about the use of cocoa shell as a food alternative in broilers.

Purpose: the objective of this research was to evaluate the productive performance of broilers fed with cocoa shell as a partial replacement for commercial balanced nutriment.

Methodology: a randomized design was used with five cocoa shell inclusion treatments as partial replacement of commercial balanced aliment: TCC2.5 %, TCC5 %, TCC7.5 %, TCC10 % and a control of each one with 25 replications. The following productive parameters were evaluated: consumption, final body weight, weight gain, feed conversion and efficiency, yield and carcass weight, viscera weight, pigmentation, feeding costs, partial net income per live chicken and partial income per carcass chicken. The results were subjected to an analysis of variance [ANOVA] with a significance of 5%, considering the initial weight as a covariate. The linear, quadratic, and cubic effects were evaluated by orthogonal contrasts.

Results and conclusions: there were no statistical differences for the variables studied between the control treatment and the substitution levels of balanced nutriment for cocoa shell flour. There was a negative linear order effect for carcass performance and pigmentation. Quadratic and cubic order effects were not observed. In relation to the economic analysis, the feeding costs observed had a substantial decrease per kilogram of meat produced for the TCC10 % compared to the control group and other treatments; while for the net income per live chicken and net income per carcass chicken, the TCC2.5 % presented the highest values. It is concluded that the partial substitution of commercial balanced aliment for cocoa shell flour in broilers does not affect productive performance and substantially reduces production costs.
