Abstract :The Black Bengal goat is an important livestock animal in Bangladesh. To assess the efficacy of selective anthelmintics against ecto- and endoparasites of Black Bengal goats and their treatment effects on body-weight gains and hematobiochemical indices, a field trial was conducted at Pahartali Thana in Chittagong district. The study was performed during the period of February 2006 to January 2007. Goats were treated with CEVAMEC®-1% insert ignore into journalissuearticles values(ivermectin); insert ignore into journalissuearticles values(T1);, ENDEX®-1500 insert ignore into journalissuearticles values(triclabendazole along with levamisole); insert ignore into journalissuearticles values(T2);, and a placebo insert ignore into journalissuearticles values(T3, untreated);. A reduction of eggs per gram count was very significant from day 7 insert ignore into journalissuearticles values(91.3% reduction); through day 28 insert ignore into journalissuearticles values(100%); with the treatment of ivermectin. The reduction rate of eggs per gram was also significant with the treatment of triclabendazole along with levamisole insert ignore into journalissuearticles values(75.8%-94.7%);. Both of the drugs were equally significant against endoparasitic infections of goats in this study insert ignore into journalissuearticles values(P < 0.05; t-test);. The percentage efficacy of ivermectin was also recorded against ticks and lice of goats from day 7 through day 28 of the trial period. The packed cell volume and hemoglobin levels increased significantly insert ignore into journalissuearticles values(P < 0.05); in both of the treated groups insert ignore into journalissuearticles values(T1 and T2);, which was indicative of effective treatments of those trial drugs. The total serum protein and calcium levels also increased significantly insert ignore into journalissuearticles values(P < 0.05); in both of the treated groups insert ignore into journalissuearticles values(T1 and T2); as compared to the untreated group insert ignore into journalissuearticles values(T3);, which was also suggestive of effective treatment. The level of serum glutamate pyruvate transaminase insert ignore into journalissuearticles values(SGPT); and serum glutamate oxaloacetate transaminase insert ignore into journalissuearticles values(SGOT); declined significantly insert ignore into journalissuearticles values(P < 0.05); in both of the treated groups insert ignore into journalissuearticles values(T1 and T2);. This result also indicates the success of those drug actions against endoparasites of goats. In conclusion, either of the drug regimens can be used against parasitic infections of backyard goats. However, in order to design a proper anthelmintic schedule against parasitic infections in backyard goats, a long-term trial, covering seasons of a calendar year, needs to be conducted.
