Abstract

To investigate the effect of chronic inhibition of the sympathetic nervoussystem oil food intake in the chicken, guanethidine (GTD, 0 or 50 mg/kg body weight/d), all adrenergic blocker, was subcutaneously administered to chicks for 4 weeks starting at 10 days of age in experiment 1, Chronic GTD decreased body weight gain and brain weight, but not heart and adrenal gland weights. Irt the second; experiment, effects of chronic GTD and dietary excess phenylalanine (Phe) oil; daily food intake were investigated at one week interval for 4 weeks. At each week, food intake was determined at 1, 2, 4, 6, 12 and 24 h after feeding. Significant dietary effects of excess Phe were found at several times iir every week, but chronic GTD administration did not alter intake of Pile excess diet.;Main effect of GTD could be detected until 2 weeks of feeding. A significant interaction between GTD and Phe treatments was detected in some times determined until 3 weeks of feeding, implied that effects of excess Phe improved by GTD. At a. final! week, dietary excess Phe decreased food intake, but the effect of GTD disappeared. Itis possible that the anorexia by excess Phe may be affected by sympathectomy ill an early week of age.
