Milk production from cows in Nigeria is not at optimum levels in view of many factors including sub-clinical mastitis. Results: The overall herd-level prevalence rate for SCM was 85.33% (256/300 heads of cows) while the quarter-level prevalence rate of SCM was 43.25% (519/1,200 quarters). The prevalence of SCM was 50.67%, 43.67%, 39.67% and 39.13% for the left fore-quarter, right hind-quarter, left hind-quarter and right fore-quarter, respectively. The Rahaji breed had the highest prevalence of SCM with 65.91% (29/44), while the White Fulani breed had the least with 32.39% (57/176). A total of 32.33% (97/300) had only one mammary quarter affected, 30.33% (91/300) had two quarters affected, 16.00% (48/300) had three quarters affected while 6.67% (20/300) had all the four quarters affected. A total of 53.00% had SCM in multiple quarters (159/300). The risk of SCM decreased significantly among young lactating cows compared to older animals (OR = 0.283; P < 0.001; 95% CI = 0.155; 0.516). The Rahaji breed had significantly higher risk compared with the White Fulani breed (OR = 8.205; P = 0.013; 95% CI = 1.557; 43.226). Improved sanitation (washing hands before milking) will decrease the risk of SCM (OR = 0.173; P = 0.003; 95% CI = 0.054; 0.554). Conclusion: SCM is prevalent among lactating cows in the Nigerian Savannah; and this is associated with both animal characteristics (age, breed and individual milk quarters) and milking practices (hand washing).Good knowledge of the environment and careful management of the identified risk factors with improved sanitation should assist farm managers and veterinarians in implementing preventative programmes to reduce the incidence of SCM.

Methodology A survey was sent to 382 dairy farmers to acquire information on the relevant risk factors associated with SCM. Results The average herd prevalence of SCM among the 189 respondents (response rate 49.5%) was 29%. Farmers who had herds with a low prevalence (<20% cows with individual somatic cell count (ISCC) >2 ¥ 10 5 cells/mL) more frequently wore gloves during milking (26% vs 62%), used individual paper towels for udder preparation (16% vs 62%), fed cows directly after milking (47% vs 87%) and more frequently treated cows with high ISCC (69% vs 80%) than farmers who had herds with a high prevalence of SCM (>30% cows with ISCC >2 ¥ 10 5 cells/mL). The latter more often used selective dry cow therapy (52% vs 24%), compared with low prevalence herds. Conclusion The prevalence of SCM in this cross-sectional study is comparable or lower than reported in other studies from North America and the European Union. The outcome provides a benchmark for the current focus of the NSW dairy industry on the management practices associated with a low prevalence of SCM, such as wearing gloves, using paper towels and feeding cows directly after milking.

Data for the study were obtained by the use of structured questionnaire. Multistage sampling procedure was employed to select 349 respondents. Descriptive statistics were used to analyze the data. The result revealed that the mean age of the participating farmers was 46years, 91% were males, and a mean farm size of 3.21 hectares. The study also revealed that 87.2%, 83% and 82.73% of the respondents respectively adopted the use of recommended fertilizer, method and dosage of fertilizer application and the use of seed dressing chemicals. The result further showed that 16.9%, 15.2% and 14.6% of the respondents respectively identified low counterpart funding, untimely disbursement of funds and inadequate mobility of extension staff as the major constraints to the effective implementation of the programme. Generally, there was a high level of adoption of the recommended farming practices among the participating farmers in the study area. The study recommends that the funding of the project should be centrally coordinated, with contributions made by all the three tiers of government.

Proportional and simple random sampling techniques were used to select 69 male and 28 female extension personnel to give a total sample size of 97 respondents. Data was collected using a structured questionnaire and analysed with descriptive statistics (means and percentages) and the Pearson Product Moment correlation analysis. The findings show that the majority of the respondents who were mostly educated to the level of diploma (73%) agreed that knowledge of mathematics/statistics is the most important (= 7.83) requirement for data management. It was also revealed that adequate training and workshops are important requirements (= 7.60) for successful data management and enhance performance of staff particularly those involved in data collection as enumerators considering that the work is cumbersome. Pearson correlation analysis shows that there is link between educational qualification, job experience and training with level of understanding of the important aspects of data management. Proficiency in mathematics and statistics is the most important requirement for an effective data management as perceived by the KADA staff.
