The objective of this work is to look for an alternative way to improve poultry feed and productivity in Burkina Faso. The study aims to evaluate the effects of the incorporation of Azolla pinnata meal in the feed ration on the growth performance of broilers. To this end, a 56-day experiment was conducted with 120 21-day-old broiler chicks to evaluate the effect of incorporating Azolla pinnata meal as a feed ingredient in the broiler ration. B. OUEDRAOGO et al. / Int. J. Biol. Chem. Sci. 15(1): 212-223, 2021 213 The roasted soybean used as a control was partially substituted with A. pinnata meal at levels of 0, 3 and 6% corresponding to three feed treatments R0, R1, R2. At the end of the trial, an increase in the weight of the subjects with increasing A. pinnata intakes in the rations (R1 and R2) was observed, although it was not significant. The consumption indices were not significantly different. Incorporation had no adverse effect on carcass yield in subjects fed Azolla meal compared to control subjects. Partial substitution of roasted soybean with Azolla meal at 3% and 6% resulted in lower feed costs per kg live weight of chicken. © 2021 International Formulae Group. All rights reserved.
