Performances zootechniques du poulet de chair soumis à un régime à base de résidus de semoule de manioc supplémenté par la spiruline (Spirulina platensis)
Cette étude a été réalisée pour évaluer les performances zootechniques d’un régime alimentaire à base de résidus de semoule de manioc supplémentés par la spiruline chez les poulets de chair. Trois (03) groupes de poussins de souche Arbor Acres soumis aux rations témoins supplémentées ou non par la spiruline ont été comparés à neuf (09) autres groupes soumis aux rations dans lesquelles le maïs a été substitué par les résidus de semoule de manioc aux taux de 50, 75, et 100% et supplémentés par 0,5 ou 1% de spiruline. Les principaux résultats ont montré que tous les paramètres de croissance se détériorent avec le taux croissant d’incorporation de résidus de semoule de manioc supplémentés ou non par la spiruline. L’indice de consommation a augmenté de l’ordre de 10; 10 et 15% respectivement avec 50, 75 et 100% de substitution du maïs dans la ration. Le rendement carcasse, le poids relatif de la tête, des pattes, du foie, du coeur, du pancréas et de la graisse abdominale évolue en dents de scie d’un traitement à l’autre. Les résidus de semoule de manioc peuvent avantageusement être supplémentés par la spiruline au taux de 0,5% dans l’aliment des poulets de chair.© 2015 International Formulae Group.

Three (03) groups of Abor Acres chicks fed on control diets supplemented or not with spirulina were compared to nine (09) other groups fed on diets in which 50, 75 and 100% of maize were replaced by cassava root waste supplemented or not with 0.5 and 1% spirulina in a completely randomized design. Results revealed that growth parameters including feed intake, weight gain and feed conversion ratio  (FCR) depressed with increasing level of cassava root waste in the diet. FCR was poorer by 10, 10 and 15% respectively with 50, 75 and 100% of maize replaced with cassava root waste. Nevertheless, supplementing with spirulina, irrespective to the level of cassava root waste inclusion, demonstrated a production advantage. Carcass yield and relative weight of organs varied from one experimental diet to another. In conclusion, cassava root waste can be beneficially supplemented with spirulina at 0.5% in broiler diets.© 2015 International Formulae Group.

Growth performance, microbial and hemato-biochemical profile, and organs histology of broiler chickens fed diets supplemented with a seasoning named Jumbo Cube as source of monosodium glutamate
Objective: this study was conducted in order to assess the effects of dietary Jumbo Cube as source of Monosodium Glutamate (MSG) on production performances of broiler chickens.
Materials and methods: 320 day-old Ross 308 broiler chicks were randomly divided into five groups of 64 chicks each. Negative and positive control groups were fed on basal diet with no supplement (R0-) and 1 gm of antibiotic (R0+) respectively and the 3 others groups were fed on diets supplemented with the quantities of Jumbo cube containing 1 mg, 2 mg and 4 mg of MSG/Kg of feed. Feed intake (FI), feed conversion ratio (FCR), weight gain (WG), blood parameters and intestinal microbial counts were evaluated.
Results: Results revealed that feeding broilers with Jumbo Cube as MSG source significantly (P [J Adv Vet Anim Res 2018; 5(2.000): 146-154
