Body weight and metabolic level in growing chickens
Abstract:
Body weight and metabolic level in growing chickens. Acta Physiol. Pol., 1977, 28 (6): 575-583. In the investigations carried out on 128 White Rock chicken the metabolic level was determined under standard conditions in chickens characterising by different growth rate resulted from different feeding levels. It was shown that the feeding level of growing chicken has an essential influence on the character of the regression between the metabolic level and body weight. It was also found that this regression is not necessarily ot the character of Kleiber's function H = aWb. The differences in the metabolic level between the chickens maintained on different feeding levels did not disappear even after 4 days of starvation. In the light of the obtained results and recent investigations by other authors the usefulness of the so-called metabolic unit of the body size based on W0.75 in context to growing animals within one species has bee criticized.
