The pattern of nutrient and energy utilization, retention and the chemical composition of the body in broilers from hatching to maturity.

The change of the body composition, of the energy content, and of the energy and protein balances was studied in male and female broiler chicks from hatching to maturity (about 140 days). The animals received corn, soybean meal and fish meal based diets which ensured maximal growth. Correlation were established between the ingested feed and the body evolution both from the point of view of quantity and quality, determining the content of protein, fat, ash, water and energy. By experiments of digestibility and by comparative slaughterings the energy and protein requirements both for maintenance and for protein and fat synthesis were determined.

The pattern of protein and energy retention and the chemical composition of the body in White Leghorn pullets.

The change of body composition, energy content and energy and protein balance was studied in White Leghorn pullets from hatching to 140 days of age. The animals received corn, soybean meal and fish meal based diets ensuring maximal growth. Correlations were established between ingested feed and body weight gain both from the point of view of quantity and quality, determining the content of protein, fat, ash, water and energy in the total body and in feathers, separately. On the basis of digestibility and comparative slaughtering the energy and protein requirements for maintenance and for protein and fat retention were calculated. The obtained results can be utilised to develop a mathematical model for energy and protein retention in growing White Leghorn pullets.

DL-phenylalanine versus imipramine: a double-blind controlled study.

In a double-blind study, DL-phenylalanine (150--200 mg/24 h) or imipramine (150--200 mg/24 h) was administered to 40 depressed patients (20 patients in each group) for 30 days. Diagnoses were established according to the International Classification of Disease (ICD). The AMP system, the Hamilton Depression Scale and the Bf-S self rating questionnaire (von Zerssen et al., 1974) were used to document psychopathological, neurologic, and somatic changes. Twenty-seven patients (14 on imipramine, 13 on phenylalanine) completed the 30-day trial. No statistical difference could be found between these two drug treatment groups (Student's t-test) using the Hamilton Depression Scale and the Bf-S self rating questionnaire. Ratings for anxiety were significantly lower in the imipramine group on days 10 and 20, but not on day 30; in addition, sleep disturbances were more influenced by imipramine on days 1, 5, and 10, but not on days 20 and 30. Separate analysis of psychopathological syndromes as somatic depressive syndrome and retarded depressive syndrome did not show a group difference (0.05 level of significance using a two-way analysis of variance). It is concluded that DL-phenylalanine might have substantial antidepresant properties. However, certain methodological considerations still warrant a careful interpretation.
