EFFICACY OF COMMONLY USED ANTHELMINTICS AND THEIR EFFECT ON BODY WEIGHT OF INDIGENOUS CATTLE AT JHIKARGACHA, JASHORE

Abstract

A coprological investigation was carried out to detect some variable wise prevalence of gastro- intestinal (GI) nematode infection in indigenous cattle and to know the efficacy of some commonly used anthelmintics on them. The faecal samples were collected from 112 indigenous cattle from Jhikargacha Upazilla of Jashore district with a random sampling. The study was conducted February 2020 to January 2021. Faecal sample examination of all the selected cattle showed that 29.44% (33) animals were affected with single type of GI nematode. Among them, Toxocara vitulorum is highly prevelant with a prevalence of 9.82%. Other species, namely Trichuris trichiura, Bunostomum phlebotomum, Haemonchus contortus and Strongyloides papillosus are also found significantly. Mixed infections were observed in 8.03% cattle where two or more species of nematodes are noticed. The prevalence of gastro-intestinal helminths was significantly higher in young cattle (50%) than adult (22.5%) cattle. About 33.33% male and 26.86% female cattle were infected with at least one type of gastro-intestinal nematode infestation. Both mixed and single infection was significantly higher in male cattle than those of female cattle. During summer season, prevalence is found higher (35.71%) than winter (20.51%) and rainy season (32.26%). Extensive rearing system is identified as more prevalent (34.78%) in gastro-intestnal nematodiasis than intensive (25.0%) and semi-intensive rearing system (26.31%). Cachectic animals having body condition score 1, are highly prevalent (33.33%) than others. The efficacy of Pipervet® and Almex® against Ascaris infection of were found 100% and 80% respectively whereas Levavet® and LTvet® were found 100% and 90.91% effective against single type of infection with Trichuris trichiura, Bunostomum phlebotomum, Haemonchus contortus and Strongyloides papillosus. The efficacy of Levavet® and LTvet® against mixed infection were 100% and 83.3% respectively . Using Pipervet®, Almex®, LTvet® and Levavet® body weight was gained after 1 month 8.88%, 10.41%, 6.57%, 6.17% respectively. These differences were not statistically significant.
