Background: The normal maize contains high zein fraction and devoid of lysine and tryptophan thus making lysine as second limiting amino acid in it. The opaque-2 and floury-2 mutants produce higher levels of lysine and tryptophan. Through plant breeding programme, bio-fortified maize (Provitamin-A enriched) is being produced. Therefore, the study was conducted to determine the effect feeding different bio-fortified maize based diets in Vanaraja birds.Methods: The experiment was conducted during January to April 2018 at ICAR-Directorate of Poultry Research. For the purpose, 175 day old chicks were randomly divided into 5 dietary groups each having 7 replicates with 5 birds each. Five experimental diets were formulated to contain normal maize (Diet 1), Vivek Hybrid 9 (Diet 2), APQH9 (Diet 3), Vivek QPM 9 (Diet 4) and white maize (Diet 5). The experimental diets fed ad libitum to all the chicks up to 6 weeks (nursery phase) and recorded performance parameters.Result: Improved feed efficiency was recorded in the group fed diet with APQH9 (Diet 3) compared to other experimental diets. The decrease in abdominal fat and increased breast muscle among the birds fed diet contained Vivek QPM 9 (Diet 4) and APQH9 (Diet 3) was recorded in comparison to other dietary groups. Hence, it is concluded that the birds fed QPM and QPM + Provit A showed an improved feed efficiency, reduced abdominal fat and increased breast muscle in Vanaraja birds during nursery phase.
