Effect of replacing corn with oak acorn with and without addition of choline on performance and tibia characteristics of broilers

This experiment was conducted to investigate the effects of dietary inclusion of different levels of oak acorn(OA) with and without choline addition in broilers diet. A total of 528 one-day-old chicks were used in a factorial arrangement based on completely randomized design, with six treatments, four replicates and 22 chicks per each. Two studied factors were choline (0 and 0.3 % diet) and OA(0, 15 and 20% diet). In starter (d 1-21) and finisher (d 22-42) diets, corn was replaced with 15 and 20 % OA, without any change in percentage of other dietary feed ingredients. The findings indicated that feeding birds with diets containing 20 % OA reduced body weight gain during starter, finisher and entire period (d 1-42) of the study when compared to the diet without OA (P
