Bulls of Harer cattle breed managed at Chercher Oda-Bultum Farmers Union beef Farm were used as study subject. A total of 130 bulls were used using double blinded randomized controlled field trial based on parallel group design from January 2018 to July 2018. The study animals were randomly assigned to the treatment group (n = 100) and control group (n = 30). The feed of treatment group was mixed with EM at dose of 5 × 10<sup>10</sup> cfu/day/head and supplemented for 90, 100 and 115 days while that of the control group was mixed with molasses, which acts as placebo. Both the treatment and control were slaughtered and two lymph nodes were collected from each animal under strict sterile condition and processed for the isolation and identification of Salmonella using standard procedure. A significant (p = 0.001) reduction in the load of Salmonella was observed in the lymph node of treatment group as compared to the control group. The load of Salmonella was significantly affected by length of feeding period and age of bulls. This study indicated that effective microbial supplementation to bulls from Harar cattle reduces the load of Salmonella in the lymph node of beef cattle thereby potentially minimizing the economic and public health impacts of Salmonella infection.展开更多

However, Ethiopia has not yet fully promoted its position as the utmost producer and exporter of khat in a global market because of its different policy discourses and illegal trade issues on khat production. The life of many smallholder households relies on khat production and its marketing in a country. Hence for thus, some information has been gathered on different aspects of khat with the objectives of reviewing khat’s impacts on the livelihood of smallholder farmers, its production status, and marketing constraints in Ethiopia. To review these objectives, data from CSA, and different published materials on khat were used. According to the review, khat production has a positive impact on securing household food insecurity and improving the livelihood status of smallholder farmers, and the largest foreign exchange-earning cash crops. However, it is exploited almost in all parts of a country’s government policy discourse on khat production and its trade legal issues, lack of infrastructure, zero access to extension services, zero tangible value addition, inadequate technology transfer, and research, and price volatility because of product perishability behavior are among major constraints threatened in khat production in Ethiopia. Its vulnerable and corrupted marketing system, zero market promotion and political dichotomy, long market chain, chronic market information, and unfair price were reported by different scholars as major problems of khat marketing in Ethiopia. From these probs: The government should analyze why and its impact on khat production discourse policy on the livelihood of smallholder households and overlook positive policy proclamation. Encouraging research and technology transfer to transform products into manufacturing industries, enhancing infrastructural and institutional facilities, and improving khat production product technologies through development, and khat production agribusiness industry transformation, institutionalizing its marketing arrangement and other related agronomic practices are among the major recommendations to forward so.展开更多
