Abstract
A Study was conducted on the incidence of subclinical
gastrointestinal nematodiasis in diary cows and heifers, and
the effect of anthelmintic treatment on their milk
production. 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, Trichostronqylus sp.,
Haemonchus sp., Cooperia sp. and Oesophagostomum sp. Of
these, Trichostronqylus 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 heamatological 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.
