abstract
368 goats that were presented to the Campus Veterinary Hospital and Ambulatory Clinical Services, Mylardevpally, College of Veterinary Science, Rajendranagar, Hyderabad, from December-2017 to June-2018 were selected and screened for gastrointestinal nematodal infestation by different techniques (gross, direct faecal smear, sedimentation and flotation), out of which 140 goats (38.04%) were found positive for gastrointestinal nematodal infestation. Goats positive for gastrointestinal nematodal infestation were randomly divided into two groups (II and III) with each group having 10 positive cases. Efficacy of ivermectin (group II) and levamisole (group III) was evaluated by egg per gram technique. Faecal examination at day 0 revealed an egg per gram of 1520 ± 156.20 and 1310 ± 126.88 in group II and III, respectively. The use of direct smear, flotation and sedimentation techniques revealed Strongyles spp., Trichuris spp. and Strongyloides spp. in these animals. Egg per gram counts of the animals treated with ivermectin (group II) is reduced by 86.22, 100 and 100% on day 3, 5 and 7 post-treatment respectively, and levamisole (group III) reduced by 77.38, 97.20 and 100% on day 3, 5 and 7 post-treatment respectively.
