  Background and Objective: Heat stress represents a major challenge for the optimal production of exotic broiler chickens in tropical environments. This study, therefore, aimed to evaluate the hatching egg characteristics, embryonic development, hatching parameters and juvenile growth of Nigeria Indigenous Chicken in crosses with exotic broiler chickens. Materials and Methods: A total of 1,000 day-old chicks were bred from Nigerian Indigenous Chickens (NIC) and exotic broiler breeder (Anak Titan) to obtain chicks whose genotypes were: 100% NIC+0% exotic broiler chicken (NIC), 75% NIC+25% exotic broiler chicken (TE), 50% NIC+50% exotic broiler chicken (FE) and 25% NIC+75% exotic broiler chicken (SE). At 36 weeks of age, fertile eggs were obtained from each cross with the use of artificial insemination. Hatched chicks were reared to determine the juvenile growth parameters. Results: The results showed no significant differences between the egg quality characteristics for the different genotypes (p>0.05). At Embryonic Day (ED) 7 of incubation, egg weight loss of TE, NIC and FE was similar but higher than those of the eggs of SE. The egg weight loss of NIC was similar to that of TE but higher than those of FE and SE at ED15. The percentage fertility of FE eggs was significantly higher than those of other treatment groups, while TE eggs were also higher than those of NIC and SE whose values were comparable. Conclusion: It was concluded that there could be a positive improvement in embryonic development and post-hatch growth of the local chicken by crossbreeding using the same genotype ratio (50:50).

  Background and Objective: The scarcity and high cost of fish meal has led researchers to evaluate the use of unconventional protein sources as substitutes for fish meal in poultry feed. This study investigated the substitution of Black Soldier fly for fish meal in broiler diets. Materials and Methods: A total of 225 fourteen-day old broilers were assigned to five treatment groups: A0 (100% of fish meal and 0% of maggot meal), A25 (25% of fish meal and 75% of maggot meal), A50 (50% of fish meal and 50% of maggot meal), A75 (75% of fish meal and 25% of maggot meal) and A100 (0% of fish meal and 100% of maggot meal). Data were collected on feed intake, organ weights, biochemistry parameters and digestibility indices. Results: Birds in group A100 had the lowest feed intake and better feed conversion ratio. Gizzard weight of the birds in A0 and A25 was similar but significantly lower (p<0.05) than those in A50, A75 and A100. Intestinal length of birds in A50, A75 and A100 were significantly longer (p<0.05). No significant difference in serum total protein and cholesterol was recorded across the treatments whereas albumin concentration in the birds in group A100 was the highest (p<0.05). Triglycerides were in the following order: A0 = A25, = A50 A75 = A100. Uric acid concentration was significantly lower (p<0.05) in (A0). Conclusion: Black Soldier fly maggot meal improved broiler productive performance without any deleterious effect and can be considered as a suitable alternative for fish meal.

Background and Objective: The use of antibiotics is associated with problems such as the presence of residues in eggs and meat and the development of bacterial resistance. These concerns have resulted in the search for phytochemical from plants such as Moringa oleifera leaf. The leaves of Moringa oleifera have been regularly incorporated into feed to improve poultry production but the profitability of this, in modern poultry production, has not been evaluated. This study, therefore, evaluated the financial implications of the use of Moringa oleifera leaves in poultry feed. Materials and Methods: A total of 600 day-old Isa brown chicks were assigned to 3 dietary treatment groups of M0 (0% of Moringa oleifera leaves), M1 (1% of Moringa oleifera leaves) and M2 (2% of Moringa oleifera leaves) from day-old to 280 day of age. Production and financial data were subjected to financial analyses using feed conversion ratio, margin approach, return on investment and break-even yield methods. Results: The study showed that there was a better profitability in the birds fed with the diet containing 1% leaves having 11.04% more income and 14% return on investment than those of M0. This improved performance was associated to the better feed conversion ratio and high egg production of the birds fed diet containing 1% leaves when compared with those fed 2% Moringa leaves. Conclusion: It was concluded that the use of Moringa oleifera leaf as a prebiotic in a poultry diet improved production performance and profit margin of hens.

Background and Objective: Despite the health benefits associated with the consumption of meat and eggs of quails, the management of the birds is still in rudimentary state in Benin. The aim of this study was to characterize quail production in Benin. Materials and Methods: A survey was conducted on thirty quail farmers through an interview supported by a structured questionnaire using the snowball method. The multiple correspondence factor analysis (MCFA) and ascending hierarchical classification (AHC) methods were used for statistical analysis. Results: The results showed that quails were raised for profitability, prestige and medicinal uses of their eggs. Quail farmers were predominantly male (93.3%) and the birds were reared in urban and peri-urban areas. Three types of quail production were identified as types I, II and III, with average flock sizes of 1288.3±955.02, 947.4±537.55 and 13171±6931.6, respectively. The majority of type I and III farmers were educated (100 and 80%, respectively) and trained in quail production (88.89 and 80.00%, respectively) unlike type II (educated: 11.76% and trained: 17.65%). Conclusion: There are on-going efforts to improve the productivity of quails in Benin Republic. Formal training is needed and more women should be encouraged to participate.

Objective: This experiment was conducted to investigate the effects of Stabilized products of sorghum enriched with lactobacilli (SPSL) on growth performance, haematological parameters and ileal microflora of Guinea fowl. Materials and Methods: A total of 520 one day old guinea fowls with average body weight of 33.02g were assigned to 4 treatments with 5 replicates (26 birds/replicate). The 4 treatments were: (1) Only basal diet (T), (2) Basal diet supplemented with antibiotics in water (T+), (3) Basal diet supplemented with the SPSL at the dose of 1.5% (T1.5), (4) Basal diet supplemented with SPSL at the dose of 3% (T3). At 12 week of age, blood samples were collected from 40 birds per treatment for haematological analysis. The birds were also slaughtered and ileal contents were harvested for microbiological analysis. Results: The results showed that there were no significant differences in the feed intake, feed conversion ratio and body weights of the birds across the treatments. Weight and length of intestine, caeca length and abdominal fat of the birds in T3 were higher (p<0.05) than those of the other treatment groups. The lymphocyte in T1.5 group was higher than those of T group (p <0.05). Total coliforms bacteria was higher in the birds of T+ and T treatment groups than those of T1.5 and T3. The level of Escherichia coli was lower (p<0.05) in the birds of T3 group compared to other treatment groups. Total coliforms in T1.5 and T3 birds were lower than those of T and T+. Conclusion: It was concluded that the SPSL significantly improved the intestinal parameters and reduced the potential pathogen bacteria.
