| Popis: |
Groups of pigs with ages between 2 months and four years that had been kept free from Hyostrongylus rubidus all their lives, were given a primary infecting dose of 4,000 H. rubidus third stage larvae. The animals were killed at various times after the patency of the worm infection and their stomachs examined either for pathological changes or for the numbers and state of development of the worms. No evidence for age resistance was found, but there was a little evidence to suggest that in older animals the rate of development of a proportion of the population was slower. The pathological picture was similar in all the pigs examined. |
