Response of slow-growing chickens to feed restriction and effects on growth performance, blood constituents and immune markers

An experiment was conducted to study the response of a slow growing chickens breed “Sinai” to feed restriction (FR) and the effects on growth performance, blood constituents and immune markers using a total number of 60 unsexed 7-d-old chicks. Chickens were housed in battery brooders during d 1 to 3...

Chickens were housed in battery brooders during d 1 to 35 of age and randomly distributed keeping similar initial body weight, in two FR treatment groups. During 0-6 d of age, chickens were fed ad libitum, a mash commercial diet. During d 7-14 of age, chickens were fed either 100 or 80 % of the daily amount of feed consumed by the control group during the previous day. From d 15 to d 35, chickens were fed ad libitum diets a mash commercial diet.
