| Popis: |
An experiment was designed to investigate a reported peri-parturient rise of nematode egg production in sows. Thirty young female pigs were infected daily over a period of several months with Hyostrongylus rubidus. After synchronization of the oestrus cycles of all the pigs, half were inseminated and the effect of pregnancy and lactation on the worm populations was determined by periodic killing of breeding and non-breeding animals. No peri-parturient rise was seen and there was little difference between the worm burdens of breeding and control pigs. Possible factors controlling the development of populations of H. rubidus in breeding sows are discussed. |
