Popis: | Infection with digestive-tract strongyles was monitored in beef cattle of the Pampas of Argentina from 1981 to 1987. The parasitological parameters were the numbers of worms harboured by tracer calves grazed for 25 days on pastures and the nematode faecal egg output of cattle grazed permanently on the same pastures. The environmental parameters were meteorological records of rainfall and temperature, and the intensity of use of uncontaminated fields. The contamination of pasture (number of nematode eggs deposited) was the key factor for predicting infection with the four genera ( Ostertagia, Cooperia, Trichostrongylus and Haemonchus ). The temperature was an important predictor only for Haemonchus infection; rainfall was not a significant contributor to the multivariable predictions. |
