In ovo toxico-pathological effects of medicinal plants used against coccidiosis on chicken embryos development and hatchability.

TOXICO-pathological effects of herbal plants have always been a major concern, but little information is provided on the toxico-pathological effects of medicinal plants used against coccidiosis. This study aimed to assess the histopathological effects of Carica papaya seeds (CPS), Azadirachta indica leaves (AIL), and Sarcocephalus latifolius root (SLR) used as coccidiostat in traditional poultry farms with various doses using the chick embryo model. A total of 420 Sasso breeder eggs at ED4 of incubation were inoculated with the extract of these plants following a 3×4 factorial design with 3 plant extracts (CPS, AIL and SLR) and 4 inoculation doses (0, 25, 50 and 100 mg/kg egg-weight).

Comparative Metabolomic Profiling of Eggs from 3 Diverse Chicken Breeds Using GC-MS Analysis.

Eggs, as a crucial source of essential nutrients for consumers, possess a high nutritional value owing to their rich composition of vital components essential for human health. While previous research has extensively investigated genetic factors influencing egg quality, there has been a limited focus on exploring the impact of specific strains, particularly within the African context, on the polar metabolite profile of eggs. In this extensive study, we conducted an untargeted analysis of the chemical composition of both albumen and yolk from 3 distinct strains of hens-Blue Holland, Sasso, and Wassache-raised under identical feeding conditions.

Chicken Incubation Conditions: Role in Embryo Development, Physiology and Adaptation to the Post-Hatch Environment.

The chicken hatching egg is a self-contained life-supporting system for the developing embryo. However, the post-hatch performance of birds depends on several factors, including the breeder management and age, egg storage conditions and duration before incubation, and the incubation conditions. Studies have determined the effect of incubation factors on chick post-hatch growth potential.

Use of Moringa oleifera leaves in broiler production chain. 1 - Effect on Sasso breeder hens performances, internal quality of hatching eggs and serum lipids.

An experiment was conducted to determine the effect of Moringa oleifera leaves (MOL) on breeder hen performance, hatching egg quality and blood parameters. A total of 180 Sasso broiler breeder hens were used for the study. They were allotted to two groups each containing 3 replicates of 30 hens of 18 weeks of age.
