Prevalence of gastrointestinal parasites in cattle in and around Cheyyar Taluk, Thiruvannamalai District

A total of 50 dung samples and 50 gastrointestinal tracts were collected from non-descript cattle slaughtered in and around Cheyyar taluk, Thirvannamalai districts of Tamil Nadu over a period of six months from March 2014 to August 2014. Parasitological examination of dung samples revealed the eggs of Amphistomes, Moniezia sp, Strongyle, Strongyloides and Eimeria sp. The overall prevalence of parasitic eggs and oocysts was 76.00 per cent. Of this overall prevalence of 76.0%, 40.0% was infected by nematodes, 36.09% by trematodes, 16% by protozoan parasite (Eimeria sp.) and 10.00% by cestodes (Table 2). The most common gastrointestinal nematodes observed in this study was the strongyle (21.05%) compared to Strongyloides (2.63%). Among the age groups (Young and Adult), younger animals had higher infection of nematodes (24.0%) and trematode (20.00%) than the adult cattle. Among sex, male cattle had higher infection of nematodes (24.0%), tremaotode (20.00%) and Eimeria sp. (8.0%) while female goats had higher infection of cestodes (8.0%). Among the season (summer and monsoon), cattle had heavier infection of trematodes only during summer months (32.00%) whereas cattle had heavy infection of nematodes (30.00%), Eimeria sp (10.0%) and cestodes (10.0%) during monsoon months. The worms collected from the rumen and duodenum was identfied as Paramphistomes viz., Cotylophoron cotylophorum, Fishoederius elongatus, Gastrothylax crumenifer and Paramphistomum cevrvi. The worms collected from abomasum were Haemonchus contortus, Mecistocirrus digitatus, Trichostrongylus axei and Oesophagostomum radiatum (Nematodes). The worms collected from intestines was identified as Moniezia benedeni (Tapeworm) and the caecum was Oeophagostomum columbiunum and Trichuris ovis. The overall prevalence of intestinal parasitic infection (worm count) was 86.0%. Among the age groups (Young and Adult), younger animals had higher infection of trematode (36.0%), nematodes (32.0%) and cestode (20.0%) than the adult sheep. All the slaughtered cattle were males. Among the season (summer and monsoon), cattle had heavier infection of trematodes worms during summer months (38.0%) whereas cattle had heavy infection of cestode worms (10.0%) and nematodes worms (32.0%) during monsoon months.
