Seasonal variations in the populations of infective larvae on pasture and the numbers of nematode eggs in feces of farmed goats


, : Seasonal variations in the populations of infective larvae on pasture and the numbers of nematode eggs in feces of farmed goats. Journal of Helminthology 64(3): 263-270

The levels of nematode egg production in goats and the availability of infective larvae (L3) on pasture were investigated on a dairy unit in New South Wales, Australia. The output of eggs by adult goats was always above 300 epg. The profile of the graph of larval availability in herbage paralleled those for temperature and rainfall, suggesting that larval peaks occurred when the temperature and availability of moisture were optimal. The dominant genus was Trichostrongylus, followed by Haemonchus, then Ostertagia. A larger proportion of Haemonchus larvae in the cultures of feces were collected during the summer months.
