Two studies on the wormburden of dairy cattle were carried out. In the first the egg output of cows was estimated within 48 hours after parturition. On basis of larval cultures the mean LPG (larvae per gram faeces) was 8. Larval differentiation showed that Ostertagia spp.-larvae were the most prevalent (87.9%), Trichostrongylus spp.-larvae 47.7%, Bunostomum spp.-larvae 13.1%, Oesophagostomum spp.-larvae 9.4%, Cooperia oncophora-larvae 8.7%, C. punctata-larvae 30.5% and Haemonchus contortus 7.7%.

In the second study the abomasal wormburden of dairy cows slaughtered at an abattoir at Leeuwarden was examined. Over the period February 12, 1979 until October 1, 1979,130 abomasa were collected. The presence of the different species was: O. ostertagi 99.2%, O. leptospicularis 3.1%, O. circumcincta 0.8%, Skrjabinagia lyrata 27.7%, S. kolchida 0.8%, T. axei 74.6%, C. oncophora 1.5%, N. helvetianus 0.8% and Capillaria bovis 2.3%. The log n transformed mean total number of adult worms was 3 197 and of the early fourth larval stages, 464. There were no obvious differences between age groups with regard to wormburden, state of arrest or stage of development of the worms. The highest percentage of early fourth larval stages were found in February (72%), decreasing in March (62%) April (38%) and May (33%). During summer the percentage was about 20% and in October it rose to 58%.
