Abstract

This experiment was conducted to evaluate the effect of physical feed form on performance and nutritional behaviors in broilers. This experiment was done in a completely randomized design with several observational with 3 treatments and 5 replicate. Dietary treatments included off of pellet form, crumble and mash form with similar components for 3 periods starter (0-10 days), grower (11-24 days) and finisher (25-42 days) were adjusted based on the requirements of Ross 308.The behaviors of eating, drinking, resting, walking. Chicks’ behavior marked in periods recorded. At the end of each period , chicks were weighted and feed intake and daily gain were measured to evaluate of performance. the best feed conversion ratio in the grower and finisher and whole of period was with crumble and pellet diet. increased Mash diet with significant effect eating and walking behavior and crumble resting behavior. Feed conversion ratio was positively correlated with eating , walking and with drinking and resting has negative correlation. According to the results of this experiment, with crumble and pellet form resting behavior increased which have most correlation with feed conversion ratio and it improved feed conversion ratio.
