It was found that all the animals examined in the two livestock farms of Kerala Agricultural University were harbouring the infection. Faecal culture was found to be the method of choice for detection of nematode infection when compared to microscopical examination of faeces. The nematodes involved, as identified by morphological examination of infective larvae were, Trichostrongylus sp., Haemonchus sp., Cooperia sp. and Oesophagostomum sp. Of these, Trichostrongylus sp. was the commonest one. Albendazole at a dose of 7.5 mg per kg body weight was administered to the animals to detect the effect of anthelmintic treatment on their milk production. A positive influence, albeit not statistically significant, was observed in all the treated groups of animals. Evaluation of haematological parameters, PCV, Hb, TRBC and TLC did not show any variation before and after treatment. The study proved that anthelmintic treatment of dairy cattle in late pregnancy and early lactation can improve their milk production.
