effect of adding different levels of therapeutic curcuma on productive traits in broiler chickens

Given the significant evolution in the global food consumption pattern, animal protein needs have increased. this pattern has been leading to intensified efforts to develop the poultry industry that adopts scientific methods and advanced technologies since poultry meat is an important source of animal protein. therefore, this study aimed to use different levels of therapeutic curcuma in the diets provided to broilers and its role in production traits. this study was conducted at the university of baghdad / college of agricultural engineering sciences. this experiment used 315 unsexed ross 308 chicks one day old. the chicks were randomly distributed into seven treatments, with three replicates per treatment, at a rate of 15 chicks for each replicate. the treatments were t1, which represents the control treatment without any addition, and t2 added 0.3% of therapeutic curcuma powder, while t3 added 0.6% of therapeutic curcuma powder). moreover, t4 represents adding 0.9% of therapeutic curcuma powder, and t5 includes adding 1.2% of therapeutic curcuma powder. finally, t6 was characterized by adding 1.5% of therapeutic curcuma powder, while t7 added 1.8% of therapeutic curcuma powder. the effect of using therapeutic curcuma powder in the above treatments showed that the use of therapeutic curcumapowder in broiler diets significantly increased (p<0.05) in the productive traits represented by body weight, weight gain, feed consumption, and feed conversion ratio. moreover, it is possible to use therapeutic curcuma powder with a percentage of 0.9%, which improves the production traits.
