Feed intake in control and disturbed quail.

*Probability resulting from two-way ANOVA. The interactions between the effects of the genetic lines and the exposure to URNS are not mentioned since they were not significant (P>0.10). **x and y indicate significant differences between hypo- and hyper-caloric diet intakes within periods and within groups (t paired test; P<0.05). “Hypo” means the hypocaloric diet, and “Hyper” means the hypercaloric diet.
