A.S. Series 74-12
Feed restriction is frequently used in handling broiler breeder hens to maximize performance and to economize feed costs. Some attempts have been made to apply this technique to egg laying strains. In the test to be reported here, 80 groups (24 hens per group) of caged egg-production strain pullets were fed four diets on a restricted and full-fed basis. The four diets provided two levels of protein (13.9 and 18.3%) and two levels of energy (2500 and 3300 Cal ME). Feed restriction was accomplished by covering the feeders at 3:00 PM and removing the covers the following morning at 7:00 AM. This permitted the restricted hens to feed 8 hours each day. The full-fed hens had access to feed 14 hours per day.
