Data from: The effects of feed restriction, time of day and time since feeding on behavioral and physiological indicators of hunger in broiler breeder hens, Poultry Science article

We used broiler breeder hens fed one of 3 feed treatments: AL (ad libitum fed), Ram (restricted, fed in the morning) and Rpm (restricted, fed in the afternoon) to control for diurnal effects. We then conducted foraging motivation tests and collected home pen behavior and physiological samples at 4 times relative to feeding throughout a 24 h period.
