Highlights • Bos indicus crossbred females had higher fecal eggs as calves than as yearlings. • More Bos indicus background had higher eggs per gram of feces through 1 year of age. • Cooperia and Haemonchus species predominated through 1 year o

An enzyme-linked immunosorbent assay (ELISA) that detects antibodies against Dictyocaulus viviparus in experimentally and naturally infected cattle was evaluated for its sensitivity, specificity, the moment of seroconversion and persistence of the an

Veterinary Parasitology, 63, 247-255

Calves, previously subjected to different rates of artificial lungworm infection for 10 weeks, were challenged with a natural lungworm infection on pasture after a 6-week housing period. The results showed a parabolic relationship between the effect

Weight gain and the course of some estimators of gastrointestinal nematode infection in calves during winter housing in relation to the level of exposure during the previous grazing season

Autor: F.W. Rietveld, A. Kloosterman, Hw Ploeger, Paul Berghen

Publikováno v: Veterinary Parasitology 56 (1995)
Veterinary Parasitology, 56, 91-106

In two experiments groups of calves were exposed to different levels and patterns of infection with Ostertagia spp. and Cooperia spp. The experimental design simulated the stereotypic pattern of herbage infestation, including a normal or a delayed mi
