Extract

Birds attempt to compensate for an E : P (energy: protein) imbalance by increasing their intake of protein or energy from selected foods and this is related to changes in the birds’ body composition caused by corticosterone treatment.

Corticosterone injections increase fatness despite increasing nitrogen and energy excretion (Bartov, 1985). More recently corticosterone has been used to modulate macronutrient selection in rats (Devenport et al., 1991; Bligh et al., 1993; Tempel et al., 1993) and chickens (Covasa and Forbes, 1995). The intake of high protein concentrate was decreased by corticosterone treatment in young chickens but not in older chickens (Covasa and Forbes, 1995). The previous results suggest that more information on corticosterone’s effect on diet selection will be obtained by using foods which can offer a wide range of choices to compose a proper diet (Covasa and Forbes, 1995). Therefore, two experiments were conducted to detect changes in protein preference in relation to reduced protein deposition and enhanced fattening induced by corticosterone in male and female growing broiler chickens.
