Energy restriction in broiler breeders during rearing and laying periods and its influence on body weight gain, conversion efficiency of nutrients, egg production and hatchability



Energy restriction in broiler breeders during rearing and laying periods and its influence on body weight gain, conversion efficiency of nutrients, egg production and hatchability



Journal Of Poultry Science: 4, 273-280



The effect of feeding measured energy (ME) allowances during rearing and laying periods on body weight (BW) gain, production performance and hatchability were evaluated in a female broiler parent line. In grower period (5-20 wk), ME required for maintenance, activity and growth was calculated targeting 100 g increases in BW/week in control (C) group. In another group, ME was quantitatively reduced by 20% (R) over C.
