Effect of in ovo inoculation of Moringa oleifera leaves extract on hatchability and chicken growth performance

After the ban of antibiotic growth promoters, plants such as Moringa oleifera are subjected to studies to investigate their effect on poultry production. Following the same goal, this study was carried out to evaluate the effect of Moringa oleifera leaves extracts on hatchability and chicken growth performance. So, 450 g of Moringa oleifera leaves were subjected to extraction. The extract obtained was used to prepare injectable solutions administrated at d 18 of incubation into 580 fertile eggs obtained from Isa Brown layer breeders. Eggs were divided into 4 groups: MO0, MO0.5, MO5 and MO50, and injected respectively with 0 mu g/ml, 0.5 mu g/ml, 5 mu g/ml and 50 mu g/ml. Results at hatch showed that 0.5 mu g/ml had the highest hatchability and the most reduced yolk sac while the day-old chicken weight, chicken quality score, the relative weight of hatching muscle, heart and liver were similar between treated groups. During the rearing period, chickens of the treated groups were heavier than the control group with the best growth rate of group MO50. These results can be explained by optimum utilisation of nutrients during incubation and the rearing period.
