The study was conducted to determine the risk factors to brucellosis in one-humped (Dromedary) camels and to determine the knowledge, attitudes and practices of camel handlers to Brucellosis in Katsina State, Nigeria. Camels in herds and those brought to the abattoir for slaughter in the north and central senatorial districts of Katsina State were sampled for the study. Structured questionnaires were administered to determine knowledge, attitude and practices of camel handlers to camel brucellosis in Katsina state, Nigeria Modified Rose Bengal Plate Test (RBPT) and Serum Agglutination Test (SAT) with EDTA were used as screening and standard tests respectively. Out of a total of 980 camel sera tested, 11.2% and 10.5% were positive with RBPT and SAT, respectively. Female had OD 1.758 (95% CI = 1.157 – 2.669, p = 0.008) more chances of getting infected than males camels. There was statistical significant association (ᵡ2= 7.189, p = 0.007) observed in the prevalence rates in favour of females. It was also observed that camels of age group 16-20 years showed highest prevalence to brucellosis. There was statistical significant association (ᵡ2 = 13.602, p = 0.009) observed in the prevalence rates according to age. It was determined that there is very poor knowledge of camel brucellosis amongst stakeholders as a result they had a "lassez faire" attitude towards the disease and no practices towards prevention of infection either to them or their animals. There is the need to carry out awareness campaigns to enlighten camel owners, herdsmen, abattoir staff about the dangers of poor hygiene during meat and milk processing, the importance of use of protective clothing when carrying out these operations and the dangers of zoonotic diseases and the dangers of consumption of unpasteurized camel milk and milk products, the public health significance of the brucellosis and that there is the need to develop a strategic plan to decrease spread of brucellosis in the study area.Keywords: Brucella, Seroprevalence, Camels, KAP, Risk Factors

A cross-sectional study was carried out to determine the status of Brucella infection in one-humped (Dromedary) camels in the North and Central senatorial districts of Katsina State, Nigeria. Nine hundred and eighty serum samples from live and slaughtered camels were tested. Modified Rose Bengal plate test (RBPT) and serum agglutination test (SAT) with ethylenediaminetetraacetic acid, (EDTA) were used as screening and standard tests, respectively. The prevalence of Brucella antibodies were 110 (11.2%) and 103 (10.5%) for RBPT and SAT, respectively. Of the 472 and 508 serum samples tested from the herds and abattoirs, respectively, 63 (13.3%) and 47 (9.3%) were positive by RBPT while 62 (13.1%) and 41 (8.1%) were positive by SAT, respectively. Based on the results, it was concluded that Brucella antibodies were present in camels in the study area. Poor management practices and mixing of camels with other species of livestock as well as unrestricted movement of camels were proposed to be the reasons for the prevalence of the disease in the study area. In view of the public health importance of the disease, it is recommended that there is the need to develop a strategic plan to decrease spread of brucellosis in the study area.

The study was carried out to evaluate the functional properties of fresh and powdered egg albumin and yolk. The experiment was carried out at Animal Product and Processing lab of the Department of Animal Science, Federal University Dutsinma. Fresh eggs were collect from the Departmental farm. Ten (10eggs) each were weighed and crushed into stainless dish and separated into albumin and yolk for sun drying. After 8 hours of sun drying the crystals were convert into powder form using grinding and sieving techniques. Samples of the powder albumen and yolk were then subjected to functional properties determination. Data collected were analyzed using Statistical Analysis System (SAS) version…2002. The result indicates that there is significant (P<0.05) differences in functional properties of both fresh and powdered Albumin. Egg white (Albumin) fresh had Foaming capacity and Foaming stability values of 20.00% and 9.66% while egg white (Albumin) powdered Foaming capacity and Foaming stability had a lesser values of 11.00 % and 2.33% respectively. The Emulsification capacity (EC) and Emulsification Stability (ES) of Fresh Albumin seems to differ having a lower value (P<0.05) functional properties of 7.00% and 2.66%, while the Emulsification capacity (EC) and Emulsification Stability (ES) of powdered Albumin had higher value (P<0.05) of 35.66% and 4.00%. Similarly the Water Absorption Capacity (WAC) and Swelling Capacity (SC) for Fresh Albumin have a lower value (P<0.05) of 1.00% and 2.00%, while the Water Absorption Capacity (WAC) and Swelling Capacity (SC) of powdered Albumin had higher

This experiment was conducted at the Federal University Dutsin-ma Livestock Teaching and Research Farm in Dutsin-ma Local Government area of Katsina State, Nigeria. The study was meant to ascertain the effect of processing techniques on crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) degradation characteristics of three differently processed Acacia hockii leaf meal (ensiled (T1), sun dried (T2) and fresh (T30) incubated in the rumen of five rams at 3, 6, 12, 24 and 48hrs. Acacia hockii leaves were collected from Dutsin-ma town and used in the  experiment as as fresh leaves, sun-dried and ensiled. Five rams with average live weight of 20kg were fistulated and used as replicates in a  completely randomized design (CRD). They were fed with groundnut haulms, maize offal and cowpea husk in ad libitum at a ratio of 70%:30% respectively along with other management practices. The results of the rumen degradation characteristics showed that there was a significant (p<0.05) difference in the soluble fraction of crude protein, acid detergent fibre and neutral detergent fibre degradation among the treatments. There was also a significance (p<0.05) difference between the outflow rates of effective crude protein digestibility, effective acid detergent digestibility and effective neutral detergent digestibility. It was concluded from the study that ensiling and drying methods of processing reduces the ant-nutritional factors and the consequent better degradability of T1 and T2. However, the results of the study also revealed that ensiling is more effective than drying hence the better degradability recorded of crude protein, neutral detergent fiber, acid detergent fiber and the effective passage rate.

Brucellosis due to Brucella melitensis infects mostly small ruminants and has been reported to be the most invasive and pathogenic species for humans. A cross-sectional sero-geospatial study was conducted in 4 and 3 Local Government Areas (LGAs) of Katsina and Sokoto States, Nigeria respectively. Sera were analysed using c-ELISA while A Global Positioning System (GPS) receiver was used to take geographic coordinates of all sampling points. Data were analysed with SPSS version 20. Chi-square test was used to measure associations among categorical variables. ArcGIS 10.3 was used to map the geospatial pattern of distribution of B. melitensis. Three-dimensional analysis was also performed using the Inverse Distance Weighted (IDW) interpolation to determine the distribution pattern of B. melitensis in unsampled LGAs. Six (10.52%), 11 (20.0%), 11(2.0%) and 23 (23.0%) sera were positive from Bakori (n=57), Baure (n=56), Daura (n=55) and Funtua (n=101) LGAs of Katsina State respectively while 4 (12.5%), 1 (5.6%), 13 (14.8%) were positive from Illela (n=22), Tambuwal (n=19) and Yabo (n=90) LGAs respectively in Sokoto State were positive for B. melitensis antibodies. All the variables tested were not statistically significant (p ≤ 0.05). The geospatial maps for both States were produced to show the prevalence of B. melitensis using c-ELISA throughout the LGAs sampled and extrapolation was done for other unsampledLGAs. Small ruminants in the study areas harboured antibodies to B. melitensis. The maps may serve as an excellent tool for active surveillance and control strategies for livestock diseases like brucellosis in the study area.
