A study was aimed to examine the effect of in ovo injection of lysine and methionine on Guinea fowl hatching traits and growth performance. Fertile eggs (n=300) were sourced from a reputable breeder farm and fumigated, weighed, and incubated. Dead embryos were removed, and living embryos were redistributed into treatment groups of control, de-ionized water, lysine, methionine, and a combination of lysine and methionine. The injection was performed on the 25th day of embryonic development, and the eggs were returned to the incubator within 30 minutes. Keets were managed intensively and starter and grower diets were provided. The Lysine injection resulted in the highest hatchability (72.5%) while Control had the highest dead in shell and weak in shell (20, and 15%, respectively). Lysine + Methionine injection resulted in the highest final body weight (1077.5g), weight gain (898.75g), and the best feed conversion ratio (2.33 %). The Feed intake was lowest (2094.75g) for lysine + methionine. It was concluded that in ovo injection of 10 mg/0.5 ml, lysine positively impacted hatchability, and methionine, alone or with lysine, enhanced growth.
