| Low-protein food decreases egg production and exogenous corticosterone (30 µg/h for 2 weeks) causes regression of ovary and oviduct, with cessation of laying in hens (Petitte and Etches, 1991). In addition, feeding 20, 30, or 40 ppm corticosterone resulted in the reduction of egg production within 4 to 8 d whilst decreasing ovarian and oviducal weights by more than 50%(Wolford et al., 1983). Laying hens are able to choose an optimum diet for egg production (Chah and Moran, 1985) but it is not known how these changes in egg production affect nutritional requirements and subsequent nutritional choice. Therefore, we investigated the influence of dietary corticosterone on diet selection in relation to egg production. Thirty Hisex brown egg-type hens aged 14 months were used, with a 14 L: 10 D lighting cycle. Before the experiment, they were familiarised with 2 foods (high protein HP, 286 g CP/kg and low protein … |
