Abstract
1. Construction and details of operation of a respiration chamber suitable for studies on the laying hen are described.2. Calorimetric data on the utilization of food energy from balanced rations and from glucose are given.3. The net energy of balanced rations for maintenance and production is 83·7% of the metabolizable energy. The figure for glucose is considerably higher.4. The maintenance requirement of the 2 kg. laying hen is 88·9 kcal. metabolizable energy/kg./day.5. Some comments are given on the significance of protein metabolism in relation to the use of indirect calorimetry for avian species.This publication has 12 references indexed in Scilit:
