Effet du niveau d’incorporation de la farine de manioc dans la ration sur les performances de croissance des poulets de chair


In order to study the effects of substitution of corn with cassava flour on broiler growth parameters, 320 one-day-old Starbro broiler chicks were distributed into16 pens of 20 birds balanced for the sex and the initial bodyweight (45.3±1,4g). Each of the experimental diets, FM0 (control without cassava) and 3 other diets FM50, FM75 and FM100 with respectively 50, 75 and 100% of maize replaced with cassava flour with particles size between  1 and 3 mm, was randomly fed to 4 groups in a completely randomized design. Feed and water were distributed ad libitum during the 49-day trial.
The FM50 diet induced the highest bodyweight (BW) with 2177±225g and 1763±194g respectively for males and females as compared with birds under diet FM100. Nevertheless, whatever is the sex, there was no significant difference (P> 0.05) between treatments FM0, FM50 and FM75 for BW. For mixed sexes, birds were heaviest with FM50 diet (P < 0.05) as compared with FM75 (1745±135g) and FM100 (1590±61g) and feed conversion ratio was best (2.26±0.17) as compared with FM100. However, there was no significant difference (P> 0.05) between treatments FM0, FM50 and FM75 for feed conversion ratio. Nevertheless, the FM50 diet produced the cheapest (P < 0.05) kilogram bodyweight (419±11FCFA) as compared with FM100 (462±24FCFA). It was concluded that under the conditions of the present trial, the performances of broilers fed a diet in which 75% of maize was replaced with cassava flour (40.5% in starter diet and46.5% in finisher) are not significantly different from that of control birds fed with a diet containing no cassava.
