Comparative Efficacy Of Anthelmintics Against Gastro Intestinal Parasites Of Buffalo Calves And Their Effects On Blood Parameters - 1995

A total of 90 (60%) out of 150 fecal samples from buffalo calves of different age groups were found positive for gastrointestinal parasites. Coprological examination revealed Toxocara vitulorurn (42.22%) as single infection and 31.11% as mixed infection. Strongy.Zoides papillosus as 21.11% as single infection arid 20% mixed infection. Nematodirus spp. 1.11% as single. Haemonchus sp., 2.22% as single and 1.11% mixed infection. Honiezia sp. 3% as single and Eimeria spp., 21% as single and 13.33% as mixed infection. Intensity of infection of gastro-intestinal parasites in buffalo calves was determined as 41.1% of calves upto 500 eggs per gm of faeces, in 22.22% calves from 501 to 1000 epg, in 16.66% calves from 1001 to 1500 epg and in 20% calves greater than 1500 epg of faeces.

Comparative percentages of means of EPG counts of infected control subgroups of groups A,B and C showed increasing trend of EPG counts by day 14. However subgroup A3, showed 'I3.l% reduction, subgroup B3 showed 61.15% reduction and C) showed 72.29% reduction in epg counts on day 3 after medication with oxfendazole. Similarly on day 7 of medication, the reduction percentage were, 95.52, 89.93 and 96.38 in respective subgroups. Albendazole in subgroups A4, 84 and C4 showed reduction on day 3, by 67.08, 64.89 and 78.57 and 95.24 respectively. On day 14, both the anthelmintics showed 100% etticacy No significant change was noted in RBC, UBC counts Hb gm/mi and PCV%, however, Eosinophils and lymphocyte counts depicted siynificant increase in the infected subgroups.
