The feed conversion ratio (FCR), feed intake and body weight gain were measuered after 3 weeks. At 42-d age, six males and six females were randomly selected from each treatment and their live weight and weights of carcass, breast, breast muscle, drumsticks, drumstick muscle and abdominal fat were determined. Terbutaline didn’t affect daily weight gain, but FCR of male chicks was reduced for 5 and 10 mg/kg terbutaline treatments comapared with the control group (p %> http://jstnar.iut.ac.ir/article-1-637-en.pdf %P 471-480 %& 471 %! %9 Research %L A-10-2-637 %+ %G eng %@ 2476-3594 %[ 2007
