    ABSTRACT: This study was conducted on randomly selected 150 samples of soft cheese (Ayib) collected from five vendors of open market places at Jimma town and its surrounding districts: Dedo, Seka, Serbo and Yebu markets to determine microbial quality. Samples were taken three times from the same vendors at different market days with sterile screw cap bottles while categorized into two: leselasa (soft) and derake (dried) soft cheeses. Samples were collected following standard procedures and then cultured on plates of aerobic plate count (APC) agar, violet red bile lactose agar (VRBL agar) and violet red bile glucose agar (VRBG agar) for aerobic mesophilic bacteria, coliforms and Enterobacteriaceae count, respectively. Bacterial identification was done by culturing on selective medium and biochemical test using Bergey’s Manual of Systematic Bacteriology Identification flow chart. The mean count of coliforms, Enterobacteriaceae and aerobic mesophilic bacteria count were 5.709, 6.504 and 8.844 cfu/g, respectively. Significant difference (P<0.05) was observed between places in all microbial count parameters and between categories in coliforms and Enterobacteriaceae count. The dominant bacterial pathogens isolated from Ayib samples in decreasing order were E. coli (20.67%), Staphylococcus aureus (18.00%), Vibrio spp. (12.67%) and Vibrio parahemolyticus (12.00%); and also Pseudomonas aeruginosa, Salmonella spp., Staphylococci spp., Shigella flexneri, and Proteus mirabilis. The high bacteria count, and isolates of different species of pathogenic suggested higher risk of public health and hence the need for improved hygienic practice at all levels during milk production and processing.

    ABSTRACT: Abstract: The aim of this study was to characterize the farm and socioeconomic characteristics of smallholder cattle producers in three districts of Ilu Aba Bora Zone of Oromia Regional State, South western Ethiopia. A stratified randomly sampling technique was adopted to sample and administer pre-tested, structured questionnaires to a total of 180 (60 from each agro-ecological zone) households. Data were analyzed using descriptive statistics such as means, percentile and GLM ANOVA.The study showed that majority (95.6%) of the respondents weremale. About 74.9% of the respondents fall within the age group of 21-50 years.Iilliteracy rate was higher in Algie(18.3%) than in Chewaka (11.7%) and Bacho (5%) districts. About 56.7, 53.3 and 61.7% respondents in Algie, Chewaka and Bacho had primary school education, respectively. The mean family size was 7.09±0.15 and no significant (P>0.05) difference was observed across the study districts. The mean land holding per household was 3.05±0.16 hectare (ha) and was differed significantly (P 0.05) between study districts.Livestock species owned by the respondents werecattle (48.6%), goats (4.6%), sheep (9.8%), donkey (0.4%), horse (3.8%), mule (0.6%) and chicken (32.2%). The major purpose of cattle productionwasmainly for draught power, followed by milkproduction and income generation.Crop and livestock sale arethe major source of income (72.8%). Family labour(96.1%) is the major source of labourused for animal management.Milking cows (89.4%) and dairy product marketing (80.2%) was the responsibility of women. About 50 and 49.4% ofherding is donebymen and boys, respectively. About 32.2, 29.4, 20.6 and 17.8% of barn cleaning is done by women, boys, men and daughters, respectively. The major decision making role for live animal marketing belong to men (95.6%). It is concluded that socio-economic characterization of smallholder cattle producers could assist to design and implement improved cattle development strategies through appropriate deliver of technological inputs. Women involvement in cattle management activities was found to be high;however their role in decision making was very low. Thus, strong and effective extension needs to be in place to empower women in decision making. Key words: Cattle Characterization Decision Making Smallholder Socio-Economic

    ABSTRACT: The study was conducted in Gomma district South west Ethiopia to assess the various opportunities and its constraints of beekeeping in the area. For this study, 6 Peasant Associations (PAs) were selected using systematic random sampling technique and interviewed using pre-tested structured questionnaires. The opportunities for beekeeping in the study areas were the existence and abundance of honeybee, availability of potential flowering plants, ample sources of water for bees, beekeepers' experience and practices and socio-economic value of honey. In addition to this study, it was observed that the major challenges of beekeeping were lack of knowledge, presence of pests and predators, lack of bee forage, pesticide poisoning, absconding, lack of beekeeping equipment and materials. More study is also required to characterize the honey bees of the area and major pests and diseases of economic importance.
