The effect of management practices on the occurrence of intestinal nematodes in pigs
Annals of Animal Science vol. 4 ( 1 ): p.163-171, 2004
A total of 2391 gilts, 8-10 weeks old, originating from 88 pedigree farms in Poland, were examined coprologically (1994-95). Nematodes were found in 25.1% of the population studied and the mean intensity equalled 1206 eggs per gram of faeces (epg). Ascaris suum and Oesophagostomum sp. were the predominant parasites, whereas Trichuris suis and Strongyloides ransomi eggs occurred only rarely. The gilts from larger herds (with a minimum of 25 sows in breeding stock) had significantly (P<0.05) lower chances of being infected compared with those from smaller farms (less than 25 sows per herd). Significant seasonal variations in the levels of helminth and A. suum infections were observed (P<0.01 and P<0.05, respectively), with the highest egg excretion in the summer months. The results suggested the great importance of management factors for the control and prevention of helminthosis in swine herds. 20 ref.
