This study aimed to determine the effect of in ovo injections of garlic and tomato extracts on the embryogenesis and neurological traits of chicken embryos with a focus on growth parameters and neurological development during the embryonic stage. A total of 300 eggs were placed in five distinct groups: Group 1 (control negative, CO, without injection); Group 2 (control positive, distilled water, DW, 0.1 mL/egg); Group 3 (garlic extract, GAR, 0.1 mg/egg); Group 4 (tomato extract, TOM, 0.1 mg/egg); and Group 5 (garlic and tomato extract mix, ATM, 0.1 mL/egg). The narrow ends of the albumins were injected with the extracts on the fifth day of incubation using a 1 mL syringe with a 2-gauge needle. The results show a significant increase (p<0.01) in embryogenesis for embryonic mass, chick body weight, hatchability, and embryo index (EI) for ATM, TOM, and GAR groups compared to CO and DW. There was also a significant increase (p<0.01) in the neurological traits of neurons, brain mass, and brain index (BI) for the ATM, TOM, and GAR groups compared to the CO and DW ones. In conclusion, adding garlic and tomato extracts into the eggs improves embryonic growth and development, increases nerve formation, and enhances nerve signal transmission within the embryo, leading to improvements in biological processes and optimal embryonic development.
