Helminth infections in Danish organic swine herds.
In nine organic swine herds, faecal excretion and pasture contamination by parasite eggs/larvae were studied in a period from March to October 1999. It was shown that the organic pigs were infected with Ascaris suum (28% of weaners, 33% of fatteners, 4% of sows), Trichuris suis (4% of weaners, 13% of fatteners, <1% of sows) and Oesophagostomum spp. (5% of weaners, 14% of fatteners, 20% of sows)...
متن کاملInfluence of helminth parasite exposure and strategic application of anthelmintics on the development of immunity and growth of swine.
Infection of pigs with the intestinal roundworm parasite Ascaris suum and strategic application of anthelmintic drugs during the growing phase of development were observed for specific effects on 1) development of immunity in feeder pigs and 2) growth rate during the finishing phase. Management treatments included maintenance in a parasite-free concrete environment, maintenance in a concrete en...

متن کاملEffects of Some Pesticides on Development of Ascaris suum Eggs
To evaluate the effects of pesticides to parasite eggs, Ascaris suum eggs were incubated with 5 different pesticides (1:1,500-1:2,000 dilutions of 2% emamectin benzoate, 5% spinetoram, 5% indoxacarb, 1% deltamethrin, and 5% flufenoxuron; all v/v) at 20℃ for 6 weeks, and microscopically evaluated the egg survival and development on a weekly basis. The survival rate of A. suum eggs incubated in n...
متن کاملEffects of Disinfectants on Larval Development of Ascaris suum Eggs
The objective of this study was to evaluate the effects of several different commercial disinfectants on the embryogenic development of Ascaris suum eggs. A 1-ml aliquot of each disinfectant was mixed with approximately 40,000 decorticated or intact A. suum eggs in sterile tubes. After each treatment time (at 0.5, 1, 5, 10, 30, and 60 min), disinfectants were washed away, and egg suspensions we...
