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.

Digestibility of Sheep Ration Containing Different Levels of Native Grass Hay and Concentrate Mixture of Wheat Bran and Dried Food Left over

The experiment was carried out at Mekelle University livestock farm, Tigray, Ethiopia. 12 male yearling Highland sheep with an average live weight of 20 + 2.5 kg (mean ± standard deviation) were used in the experiment. The objective of the study was to investigate the effect of digestibility of sheep ration containing different levels of roughage and concentrate mixture on performance of highland sheep. Food left over was collected from Mekelle University student cafeteria and dried with sun light for 3 - 4 days. The experimental design was a randomized complete Block design (RCBD) with four treatments and three replications. The experimental animals were grouped into three blocks based on their initial live body weight, which was determined by weighing after overnight fasting. The experiment was carried out for 15 days including 5 days of adaptation period and 3 days of adaptation and harnessing (fecal bags). At the end of the feeding trial, digestibility trial was carried out for seven consecutive days. There was significantly higher (P 0.05) total DM intake in the supplemented group than in the control treatment. Digestibility of DM and OM were non-significance (P > 0.05) for all treatments. Generally, the present study indicated that supplementation of Tigray highland rams with concentrate mixture had an effect on performance of sheep and the effects were relatively more pronounced on rams supplemented with the highest level of concentrate mixture.

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.

Management Practices and Production Constraints of Indigenous Somali Cattle Breed in Shabelle Zone, Somali Regional State, Ethiopia

This study was conducted in Shabelle zone of Somali Regional State to assess management practices and production constraints of indigenous Somali Cattle. A total of 200 household heads were selected from four cattle potential districts;Dhanan, Ber’ano, Godey & Adadle. The relevant information was collected through semi-structured questionnaire, focus group discussion, key informants interview, and personal observations. Majority of the respondents were illiterate. The average cattle holding size was 8.97 heads/household and cattle were mainly kept for milk production. The major feed resources in the study area were natural pasture and crop residue, and communal grazing was the most important feeding system in the area. Feed shortage was a problem hindering cattle production in the study area during dry season mainly January up to March. Animals traveled long distances to watering points (>5 km) during dry season, while in wet season, animals were watered in nearby water sources. Cattle housing was open kraal fenced with the thorned plenty acacia trees and calves were housed separately from other cattle. Breeding in the study area was uncontrolled and was bred with their own or neighbors’ bull. Age at first mating, age at first calving and calving interval were 3.25 years, 4.05 years and 16.56 months, respectively. The daily milk yield and lactation length were 2.22 liters and 8.07 months, respectively. The production and reproduction performance of Somali cattle was relatively higher than other local breeds in the country mainly in terms of milk yield and fertility potential under the existing environmental conditions. The major constraints of cattle production were feed shortage, disease, water scarcity, lack of veterinary services, marketing problem and predator. Among those constraints, inadequate supply of quality feed, diseases and water shortage were the main reasons for low productivity of cattle and are the major factors limiting productivity. Therefore, to sustain the production system in the study areas, it is recommended to improve the current condition of communal rangelands through management of degraded areas by awareness creation on the value of these common resources and development of rules and regulation to sustain the existing resource and implement over the utilization of communal/pastoral rangeland management systems to reduce constraints such as shortage of feed, drought and grazing land deterioration which perpetuated through time due to land-use changes and seasonal fluctuation).
