The main protein sources used in broiler chicken diets, such as soybean meal and fishmeal, are costly, and one potential alternative is black soldier fly larvae meal (BSFLM).This study aimed to determine the incorporation rate of full-fat BSFLM in broiler chicken diets for optimum zoo-economic performance. The experiment involved 250 day-old unsexed broiler chickens randomly allocated into 25 batches. Five different levels of full-fat BSFLM incorporation (0%, 4%, 8%, 12%, and 16%) were tested during a 49-day experiment. Zootechnical data, economics indexes, and carcass quality were determined. Results indicated a significant decrease in feed intake with the increase of full-fat BSFLM. At the end of the experiment, the broiler chickens fed BSFLM4 demonstrated the highest live weight and the best FCR, with no statistical difference. In terms of economic parameters, the control diet showed the highest feed cost and the lowest economic feed efficiency, without a significant difference. Full-fat BSFLM incorporation did not significantly affect carcass yield. However, chickens receiving BSFLM 16% indicated having a lower zootechnical performance. A full-fat BSFLM incorporation rate of 12% into broiler chicken feed could improve zoo-economic performance in the current study. Moreover, BSFLM could serve as a cost-effective protein source.

L’alimentation joue un rôle déterminant dans la réussite et la rentabilité économique des productions avicoles. Lors de la formulation d’un aliment efficient, son coût et sa qualité nutritionnelle qui permet de couvrir tous les besoins nutritionnels essentiels des volailles doivent être considérés. Ce travail basé sur la collecte des articles, fait la revue des étapes à suivre pour la formulation d’aliment de volaille et décrit les méthodes qui ont été utilisées dans la formulation d’aliment de volaille. Le carré de Pearson, l’équation algébrique simultanée, la méthode matérielle et la méthode essai et erreur sont des méthodes manuelles utilisées pour la formulation d’aliment de volaille. Les programmations linéaire, non linéaire, multi objective et quadratique sont quant à elles les méthodes de programmation mathématique de formulation d’aliment de volaille. Les méthodes manuelles permettent de faire une formulation avec peu d’ingrédient et les méthodes mathématiques permettent de faire une formulation à moindre coût. © 2015 International Formulae Group.

Introduction: The cost of poultry feed directly impacts production yield. The search for feed formulations based on less expensive products is, therefore, an alternative to improve the profits of producers. This study was conducted in Maradi at the Regional Center for Agronomic Research of the National Institute of Agronomic Research of Niger to assess the effect of roasted Faidherbia albida pods on the zootechnical performance of Isa Brown laying chickens. Materials and methods: A total of 200 Isa Brown laying chickens, aged 21 weeks, were randomly assigned to four feeding groups with five replicates each. The chickens were housed in a 5 m × 10 m building, with 10 chickens per replicate in blocks of 1.71 m². The building featured ventilation, natural lighting, and bedding made from peanut shells. Apart from the control feed (F0), the experimental feeds contained 5% (F5), 10% (F10), and 15% (F15) crushed pods of Faidherbia albida roasted at 110°C. Millet and wheat bran were the main energy sources, while fishmeal and groundnut cake provided protein. Water was provided ad libitum to all chickens. The feed was distributed over 2 months. Results: The results showed that feed ingestion increased significantly with F10 compared to the control, while consumption remained comparable among the control, F15, and F5 groups. The incorporation of roasted Faidherbia albida pods led to a significant decrease in the feed conversion ratio, with a significant difference among the treatments. The best feed conversion ratio was obtained with the F5 ration, followed by the F0 control. Conclusion: The inclusion of Faidherbia albida in the diet of chickens is beneficial for egg production. The optimal incorporation rate for roasted pods of Faidherbia albida was determined to be 10%.

This study aimed to investigate the impact of incorporating locally available ingredients into the diet of young indigenous chickens in Niger on their growth performance. Two hundred chickens, aged 6 weeks, were utilized in the study and randomly assigned to four groups of ten birds each, housed on peanut shell bedding. The diets were formulated using a variety of local ingredients including millet, wheat bran, millet bran, peanut cake, sorrel seeds, fish meal, locust meal, moringa leaves, and bone meal. Water was provided ad libitum to all birds, and the feeding trial lasted for 4 months. Results revealed that the third diet was the most preferred by the local chickens. The diet significantly influenced the live weight of the chickens in the second month (P=0.000) and showed a significant effect during the third month (P=0.020) of the experiment. Sexual dimorphism was observed between hens and roosters for diets 2, 3, and 4. Statistical analysis indicated a significant difference in the Average Daily Gain of local chickens among the different treatments during the first month. Additionally, the diet significantly influenced the consumption index of local chickens during the first month of the experiment (P=0.055). Based on the findings, it is suggested that Diet 2, containing fish meal, can be utilized in areas where fish availability and accessibility are high. Conversely, Diets 3 and 4 may be more suitable for regions prone to locust infestations. To facilitate the adoption of these dietary formulations, it is recommended to replicate the experiments in rural settings.

Background and Objective: The low guinea fowl egg hatchability and the high keet mortality are the main constraints that limit guinea fowl production. The effects of vinegar as a disinfectant on the egg hatchability and keets growth performance were evaluated through experimentation at CERRA Maradi (Niger). Materials and Methods: Bleach at 10% (B10), vinegar at 10% (V10) and vinegar at 15% (V15) were used for egg disinfection. One hundred and twenty eggs from local guinea fowl were divided into three groups. Each group was disinfected with one of products. Eggs were incubated for 28 days with 4 replicates. Keets from each group were divided into three replicates to assess growth performance for 5 weeks. Statistical analysis was performed with R 4.1.0. Results: Results showed that V10 had a 2.7 and 3.32% higher hatchability than B10 and V15 groups respectively with non-significant differences (p = 0.89). The mortality was recorded in keets of B10 and V10 groups. No mortality was recorded in V15 group. Feed intake, live weight, daily weight gain and feed conversion ratio were not statistically influenced (p>0.05) by the type of disinfectant through experimentation. Conclusion: Compared to bleach, vinegar appears to be a new alternative for guinea fowl egg disinfection for incubation. At 10% is best suited for local guinea fowl egg hatchability and at 15% for keet survival and growth performance. APA-7 Style Nouri, B., Ibrahim , K.A., Bagalam Roufahi, H.E. (2024).
