Inocuidade da infestação experimental por Ascaridia galli (Schrank, 1788) e, do tratamento pelo Bayer L 13/59 (Neguvon), medida pelo desenvolvimento ponderal, consumo e eficiência de ração comercial, em aves Leghorn

Abstract

The authors studied the ponderal development of five groups of Leghorn chickens, experimentally infested with Ascaridia galli (Schrank, 1788) and treated with Bayer L 13/59 (Neguvon). At the end of the 16 weeks period of the experiment, the infested chickens were killed for valuation of efficiency of the given medicine. Weekly weights and body gain which were obtained throughout the experiment, as well as the feed consumption and the efficiency of feed utilization, were estatiscally interpreted. Differences which appeared between groups were not significant in neither of the adopted interpretation criterions. By the orientation which was followed in the present work, it seems licit to conclude that experimental infestation as well as the Bayer L 13/59 (Neguvon) treatment, not change the chickens' normal development.
