Basal Metabolism in Growing Chicks

Energy Utilization of Growing Chicks in Various Nutritional Conditions

For the last two decades, energy utilization of growing chicks has been studied more and more. This paper focuses on the energy utilization estimated by the metabolizable energy (ME) values and the efficiency at which ME is used for growth of chicks under various nutritional environment. Degree of saturation of dietary fats is responsible for nitrogen-corrected apparent metabolizable energy (AM...

Should Leg Weakness in Growing Chicks Be Called Rickets?*

The authors (1, 2), as well as other investigators (3) in the field of poultry nutrition, have called the condition in growing chicks, popularly known as leg weakness, rickets. The use of the term rickets is in harmony with the idea expressed by Park (4) in a discussion of the etiology of rickets in which he states, “Increasing knowledge concerning rickets has made it necessary to broaden the v...

Factors Affecting Basal Metabolism

Superficial observations have led us to the general belief that the vital processes are much the same with average individuals. It is true that we are inclined to classify people as high-strung and nervous on the one hand and phlegmatic on the other; yet, on the average, the normal individual apparently has a metabolic plane comparable to his neighbor’s, for the general uniformity in the energy...

Metabolism of dehydroretinyl ester in White Leghorn chicks.

1. The metabolism of dehydroretinyl ester has been studied in vitamin-A-deficient white leghorn chicks. Dehydroretinyl ester was metabolized to 3-hydroxyretinol diester, 3-hydroxyanhydroretinol and rehydrovitamin A2 which were isolated from the intestines and livers of chicks. 2. The metabolism of 3-hydroxyretinol diester and 3-hydroxyanhydroretinol, which were immediate metabolites of dehydror...
