Data from seven experiments with Ascaridia galli-infected chickens have been considered. The results of treatment with neutral and basic copper, zinc and copper–zinc salts and inorganic and organic manganese compounds have been compared. An optimal therapy, containing a pure Cu basic salt (Cu2(OH)3Cl) and an organic Mn compound (2Gly.MnCl2.2H2O), is proposed to correct mineral deficiencies and pathological symptoms and to ensure lower mortality and higher gains in body weight. A mathematical model has been proposed for the growth of a healthy chicken. The relative rates for two growth stages have been determined by the model using data from mean chicken weights. The time course of the average biomass of a single A. galli has been theoretically derived from the same logistic equation describing chicken growth, which in turn might explain, phenomenologically, the mechanisms involved in the biomass growth of eukaryote organisms.
