The survey of the intestinal parasites of the swine in Nakhon Pathom Province was performed by egg, oocyst and cyst identification in 346 fecal samples. In suckling piglets, 4.08%, 6.12%, 6.12%, 34.69%, 18.37%, and 22.45% were infected with Ascaris suum, Trichuris suis, Strongylates, Strongyloides ransomi, Coccidia and Balantidium coli respectively. The relative incidence of these parasitic infection was higher in the fattening pigs. Ascaris suum, Trichuris suis, Strongylates, Strongyloides ransomi, Metastrongylus spp. Coccidia, Balantidium coli and Trichomonad were found in 31.15%, 35.52%, 32.24%, 31.15%, 0.55%, 35.52%, 37.70% and 0.55% respectively of the fattening pigs. The percentage of breeding pigs infected with Ascaris suum, Trichuris suis, Strongylates, intestinal flukes, Coccidia, Balantidium coli and Trichomonad was found to be 9.65%, 4.39%, 68.42% 12.28%, 38.60., 42.98% and 0.88% respectively. By parasitic identification, the examination of the gastrointestinal tracts in 82 piglets, 1-8 weeks of age, revealed 2.44%, 67.07%, 39.02%, 40.24%, and 2.44% of the piglets infected with Ascaris suum, Strongyloides ransomi, Trichuris suis, Oesophagostomum spp. and Globocephalus spp. respectively. The control of Strongyloides ransomi infection was studied in 15 litters with the total of 132 suckling piglets, 1-2 weeks old. Each litter was divided into nontreated control and treated groups; but only the latter was orally treated once with 100 mg/kg. body weight of Thiabendazole. Each piglet was weekly weighed until weaned. The average increase in growth rate found to be equal, 0.89 kg. per week in both groups.
