Hygienic Production and Post-Harvest Handling Practices of Raw Camel Milk in Degahbour District of Jarar Zone, Somali Regional State, Ethiopia

A cross-sectional study was carried out to assess hygienic production and postharvest handling practices of raw camel milk in Degahbour district. The survey studies were based on a total of 120 (2 production systems * 2 rural kebele * 30 households) milk producers, which were selected from Degahbur district using stratified sampling technique. Data from the selected producers were collected using questionnaire survey and field observation. The results showed that the majority of the sampled household heads in pastoral (93.3%) and agro-pastoral (76.6%) production systems were illiterate. Moreover, none of the respondents in the study area had training on hygienic milk production and postharvest handling practices. The study result also indicated that none of the respondents in the study area washed the udder of milking camel before milking. Moreover, only 6.6% of pastoralists and 25% of agro-pastoralists wash their hands before milking. Equipment made of wooden materials are mainly used for milking, whereas, plastic jerry-cans were most commonly used for storage. About 45% of the pastoralists and 81.6% of the agro-pastoralists were cleaning milk vessels regularly;however, majority of the respondents both production systems were using water from non-tap sources for hygienic practices. Bosciaminimifolia, Acacia ethaica and Blanitesgalabra were the most commonly used plant species for smoking in the study area. Therefore, hygienic production and postharvest handling practices should be followed to improve the quality and suitability of camel milk for its intended use in the study area.

Microbiological Quality of Goat Milk in Degahbur District of Jarar Zone, Somali Regional State, Ethiopia

A cross-sectional study was carried out to evaluate microbiological quality of raw goat milk in Degahbur district of Jarar zone, Somali Regional State, Ethiopia. A total of 40 pooled raw goat milk samples (each with a volume of 450 mL) were collected from the udders and milk handling equipment of targeted goat milk producers in the study area. The milk samples were subjected to laboratory analysis to evaluate total bacterial count (TBC) and total coliform count (TCC) in order to determine the microbiological quality of the raw goat milk in the study area. The study showed that the mean total bacterial count (TBC) and total coliform count (TCC) for raw milk samples collected from the udder were 4.92 ± 0.23 and 2.68 ± 0.36 log10 cfu·mL-1, respectively. The mean counts for samples collected from milk equipment were 5.61 ± 0.32 and 3.93 ± 0.21 log10 cfu·mL-1 for TBC and TCC, respectively. The values for the samples collected from pastoral production system were 5.63 ± 0.13 and 4.02 ± 0.20 log10 cfu·mL-1 for TBC and TCC, respectively. The average means of TBC and TCC for samples collected from the agro-pastoral production system were 4.9 ± 0.41 and 2.59 ± 0.37 log10 cfu·mL-1, respectively. Significant difference (P 0.05) in mean TBC and TCC was observed between milk samples collected from pastoral and agro-pastoral production systems as well as milk samples collected from udders and milk handling equipment of the producers. It could be concluded that both TBC & TCC of goat milk samples collected from the udder as well as from the milk handling equipment of producers exceeded the acceptable limits. This indicated that production practices performed during milk production and postharvest handling in the study area were unhygienic. Therefore, hygienic and proper milk production procedures should be followed to improve the quality of goat milk for its intended use in the study area.

Handling and Hygienic Production Practices of Goat Milk in Degahbur District of Jarar Zone, Somali Regional State, Ethiopia

A cross-sectional study was carried out to assess handling and hygienic production practices of goat milk in Degahbur district of Jarar zone, Somali Regional State, Ethiopia. A total of 120 households were purposively selected for this study using a stratified sampling technique. The data were collected through the questionnaire, field observations, key informants interview and focus group discussions. The study showed that majority of the sampled households were illiterate. The goats were kept in an open kraal made of thorny acacia trees on an earthen floor that had no roof. The goats were milked inside these open kraals, and were sometimes contaminated with muck and animal dung mainly the rainy season which could raise the possibility of milk contamination & spoilage. Moreover, traditional hand milking was the only milking method and majority of the respondents didn’t wash their hands and the udder of the animal before milking, indicating low community awareness and knowledge of sanitary milk production procedures. Plastic equipment which is difficult to clean and can increase milk contamination and spoilage was used. About 43.3% of the pastoralists and 76.67% of the agro-pastoralists were cleaning milk vessels regularly. The most often used plant species for smoking milk handling equipment in the study area to extend shelf life and add flavor & aroma were Acacia ethaica, Blanites galabra, and Solanum Carense. The main constraints to hygienic goat milk in the area were identified to be poor barn hygiene, poor production procedures, disease, source of washing water and lack of extension services. In general, it can be concluded that handling and hygienic production practices of goat milk used in the study area were unsanitary, which may have been primarily caused by the community’s lack of awareness & understanding as well as a lack of supporting infrastructures. Therefore, the concerned bodies should place a high priority on the improvement of hygienic practices by carrying out various relevant development interventions, such as raising milk producers’ awareness, improving the health of goats, and providing the necessities for milk handling.

Identification and Chemical Composition of Major Camel Feed Resources in Degahbur District of Jarar Zone, Somali Regional State, Ethiopia

This study was conducted to identify major available camel feed resources and determine their chemical composition in Degahbur district. A total of 120 respondents were selected using purposive sampling technique. Data from the selected actors were collected using a semi-structured questionnaire survey, focus group discussion and field observations. The study revealed that the majority (82.5%) of the respondents in the study area were male headed households. Browsing trees and shrubs were the major available livestock feed resources both in dry (51.6%) and wet (68%) season, and followed by herbaceous species (26.6 and 23.7% for dry and wet season, respectively). The study identified about 20 herbaceous, 24 trees, 11 shrubs, 7 bush and 17 grass species which are used as camel feed in the study area. Chemical composition analyses of the sampled feeds indicated that there was a significant difference in crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) between species in different seasons. The NDF contents in the current study were above the critical value of 60% which was reported to result in decreased voluntary feed intake, feed conversion efficiency and longer rumination time. In general, the findings indicated that the use of improved forages and agro-industrial by-products as camel was minimal;thus, camels were fed on available feed resources which are poor in nutritional quality without any supplementation. Therefore, the study suggests the need for improving camel feeding practices in the study area to enhance camel productivity.

Microbiological Quality of Raw Camel Milk in Degahbour District of Jarar Zone, Somali Regional State, Ethiopia

A cross-sectional study was carried out to evaluate microbiological quality of raw camel milk in Degahbour district. A total of 40 pooled raw camel milk samples (each with a volume of 450 mL) were collected from the udders and milk handling equipment of producers in Degahbour district. The raw milk samples were subjected to laboratory analyses to evaluate standard plate counts (SPC), total coliform count (TCC) yeast and mold count (YMC) to determine the microbiological quality of the raw camel milk in the study area. The overall mean SPC, CC and YMC for raw camel milk samples collected from the udder was 5.35 ± 0.19, 2.59 ± 0.16 and 1.71 ± 0.12, respectively. The overall mean counts for samples collected from the equipment of producers were 6.72 ± 0.17, 4.71 ± 0.23 and 1.61 ± 0.21 for SPC, CC and YMC, respectively. Significant difference (P 0.05) in mean SPC, TCC and YMC was observed between milk samples collected from pastoral and agro-pastoral production systems as well as collected from udders and milk equipment. In general, it was concluded that raw camel milk samples collected from the udder as well as from the equipment of producers were contaminated with SPC, CC and YMC, with loads exceeding the respective acceptable limits. Therefore, hygienic production and postharvest handling practices need to be followed to improve the quality and suitability of camel milk for its intended use in the study area.
