Effect of Epinephrine and Bromocriptine on Ovary Folliculogenesis and Productive Traits of Laying Hens

An experiment was conducted to study the effect of Epinephrine (EP) and bromocriptine (BR) on productive traits of laying hens. Thirty White Leghorn hens, 50 weeks old, were divided into three equal treatments (with 10 hens for each treatment): control, physiological serum (0.5 mL/hen/week), EP (0.5 mL/hen/week) and BR (100 g/kg of body weight (BW); w/v in absolute alcohol). Hens were injected once a week for 10 weeks. At the end of the experimental period, all hens were killed by decapitation. Ovaries, oviducts and ovarian follicles were examined. Ovary folliculogenesis was affected (P
