Abstract:
Gastrointestinal parasite of livestock are nematodes, trematodes, cestodes and
protozoans (including coccidians) which represent an important cause of reduced
productivity of goats worldwide. Anthelmintic treatment is an effective way to
control these parasites, the present study evaluated the effect of an anthelmintic
drug in indigenous goats of a livestock farm in Puliyankulam, Vavuniya district of
Sri Lanka from mid of March to May 2021. A randomly selected 20 indigenous goats
were divided into following groups: below one year, one to three years, above three
years and control group which was selected without considering age. The fecal
samples were collected and treatment groups were subjected to oral dosing of
closeted 96% and abamectin 4%. Then fecal samples examined using McMaster
techniques to count the egg per gram/ oocyst per gram of gastrointestinal parasitic
species for ten weeks with two weeks interval. The results were analyzed in SPSS
statistical package through the ANOVA table. The result showed 100% Nematode
population (Trichostrongylus spp., Strongyloides spp., and Trichuris spp.) in goats
was effectively controlled in two weeks after of anthelmintic treatment. Drug was
not effective to control Eimeria spp. and Monezia spp. After four week of treatment
Trichostrongylus spp. was reappeared in all treatment groups and Strongyloides spp.
was reappeared only in one to three years goats. After eight week of treatment all
Nematodes species were increased because the effectiveness of drug was highly
reduced. The closantel 96% and abamectin 4% oral dosing was effective to control
Nematode species less than eight weeks.
