Gastrointestinal parasites are economically important in the dairy industry. A study was carried out to evaluate the therapeutic efficacy of anthelmintic drugs (Tetraclozan 3400 mg and Albendazole 2500mg) for the treatment of GIT worms in cross-bred cows at Holeta research center. A total of sixty crossbred cows were purposively screened and divided into three groups for the current study. The first groups served as untreated control, the second and third groups were treated with Albendazole and Tetraclozan drugs respectively. Moreover, fecal samples were collected before and after treatment to count the eggs per gram (EPG) of feces and to evaluate drug efficacy percentage. Efficacy for each anthelmintic was determined by the Fecal Egg Count Reduction Test (FECRT). The mean EPG count before and after treatment with Tetraclozan drug on 0. 14 th and 21 st days was 520±102.1, 100±54.6 and 15±6.7 respectively whereas the mean EPG count on 0, 14 th and 21 st days before and after treatment with Albendazole drug was 450±127.2, 150±46.2 and 20±6.8 respectively. The overall percentage efficacy of Tetraclozan and Albendazole drugs were 97.11 and 95.5 percent respectively. The study indicated that the two anthelmintic drugs were efficacious against worm infection and thus, leads to reduction in EPG count. It is important to explore the detailed pharmacokinetic and toxic effects of these drugs for wide therapeutic uses in animals. It is also recommended that the clinical responses of GIT helminthes to prophylactic and therapeutic drugs need to be periodically monitored in the farms and further introduced to smallholder farmers.
The survey was conducted to assess urban dairy production and waste management system in Oromia Special Zone around Finfinnee, Ethiopia. The three study towns (Burayu, Sululta and Sebeta) were purposively selected due to the high potential for commercial dairy production. A total of 90 commercial dairy producers 30 from each town who at least own 10 dairy cows were randomly selected. The farmers interviewed individually using the survey questionnaire. The collected data were analyzed and the study revealed that 47.8 and 52.2% of the interviewed were female and male respectively. Next to daily laborers, household wives shared larger responsibility for feeding (21.1%), milking (28.9%) and cleaning (13.3%). The genetic composition of dairy cows in the study areas ranges from 50% exotic gene inheritances to pure (100%) exotic Holstein Friesian. Accordingly, 50, 62.5, ≥75% and pure Holstein Friesian cows account for about 24.4, 38.9, 24.4 and 11% of the herd, respectively. The major sources of feed were both formulated feed and feed that mixed at home (55.6%) and tap water (74. 4%). The average age at first calving, calving interval and days open was 2.26±.05years 20.8 ± 0.05 months and 161.76±34.80 days respectively. The major waste in the farm is manure (73.3%) and followed by feed left over (14.45%) and dust (12. 25%). High price feed, shortage of land, unavailability of dairy cow/heifer in time, feed quality, unavailability of feed in nearby area, diseases and lack of access to credit, shortage of water and inadequate training were among the major constraint of dairy production that need urgent intervention to utilize the untapped resources in the area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
