Materials and methods: The study was conducted with three groups of ten mecheri lambs each. Group I served as untreated control and group II and III were treated with fenbendazole @ 5 mg/kg body weight and 7.5 mg/kg body weight, respectively. All the lambs were subjected to haemato-biochemical observations, body weight recording and collection of faeces for egg counting before and after the treatment. Results: Fenbendazole in both the doses had beneficial effect on haemato-biochemical observations like haemoglobin, total erythrocyte count, total protein, albumin, aspartate aminotransferase and alanine aminotransferase besides showing efficacy as an anthelmintic. The drug also increased body weight gain significantly at higher dose as compared to untreated control. Conclusion: The results support that fenbendazole has the potential for modulating growth of stunted mecheri lambs.enEgg per gramFenbendazoleHaemato-biochemical observationsMecheri lambsArticle
