[Effect of treatment on gastrointestinal nematode infection of heifers and their weight gain in southern Poland].
The level of infection with gastro-intestinal nematodes in heifers of 3 farms (668 head) was studied by coproscopic methods and the efficacy of treatment was evaluated. Extensiveness of infection reached 80% and intensity (EPG) - 120. Comparative studies of weight gains of heifers treated and untreated revealed that the best results were obtained in heifers treated twice a year in May and August. The efficacy was estimated at 93% with respect to extensiveness of infection and at 97% for EPG. Mean final weight gains of the treated heifers were 8,0-16,8 kg higher compared to those of untreated heifers. The mating time for treated heifers was about 30 days earlier than that for untreated ones.
