Brucellosis disease is problematic in early abortion in herds, reduces the economic value of farm animals, reduces milk production and limits the breeding efficiency of cattle. A study was conducted to determine and compare the prevalence of antibodies against Brucella abortus in cattle under same husbandry practices at the Njala University, Njala campus and the Newton cattle holding ranches. A total of 80 cattle was randomly sampled and screened for the presence of B. abortus utilizing the Rose Bengal Plate Test (RBPT). Results indicated that the general seroprevalence was 57.5% in Njala University cattle ranch and 92.5% Newton cattle ranch. The prevalence of infection increased with the age of animals i.e. from 3.75% to 47.5% (22.5%) in age groups <3yrs to 3-5yrs (5-8yrs), respectively. The female animals were more infected (52.5%) than the males (22.5%). The disease was more prevalent among different age groups and sexes in Newton cattle ranch than in Njala University. Findings showed no significant difference between the prevalence of B. abortus in the cattle of Njala University and Newton cattle ranches. The prevalence of brucellosis was however enzootic at the two studied sites. This study is relevant for policy makers, researchers, ministry of agriculture and the public for the promotion of regular testing of cattle and utilizing appropriate mitigation strategies to minimize the risk of the brucellosis disease.

The aim of this experimental study was to evaluate the influence of anaerobic digestion and storage on indicator microorganisms in swine and dairy excreta. Samples were collected every 90 days for 15 months at eight farms, four pig, and four dairy farms, four of them having a biogas plant. Moreover, to evaluate storage effects on samples, 20 l of manure and slurry taken at each farm (digested manure only in farms with a biogas plant) were stored in a controlled climatic chamber at 18 °C, for 6 months. The bacterial load and the chemical-physical characteristics of excreta were evaluated at each sampling time, stored slurry, and manure were sampled and analyzed every 2 months. A high variability of the concentration of bacteria in the different excreta types was observed during the experiment, mainly depending on the type and time of treatment. No sample revealed either the presence of Escherichia coli O157:H7 or of Salmonella, usually linked to the temporary rearing of infected animals in facilities. Anaerobic digestion and storage affected in a significant way the reduction of indicator bacteria like lactobacilli, coliforms, and streptococci. Anaerobic digestion lowered coliforms in pig slurry (- 2.80 log, P < 0.05), streptococci in dairy manure (- 2.44 log, P < 0.001) and in pig slurry (- 1.43 log, P < 0.05), and lactobacilli in pig slurry (- 3.03 log, P < 0.05). Storage lowered coliforms and the other indicators counts, in particular in fresh wastes, while clostridia did not show a reduction in concentration.
