Based on unpublished reports, serotype O has been incriminated as the sole serotype present in Oman. The present study was conducted in the Dhofar region of the Sultanate of Oman between August 2003 and March 2004 with the objective of determining the seroprevalence against FMDV in Dhofari cattle. Sera samples were collected from 395 cattle in 19 different herds. Sera underwent screening using a Liquid Phase Blocking ELISA to determine the antibody response to the serotypes O, A, C, Asia 1, Sat1, Sat 2, and Sat 3. The overall seroprevalence of FMD was 52.1% (n=206). Of the seropositive animals, 77.7% were positive for type O and 22.3% for type A. There was no significant variation in seroprevalence among different sex and age groups; however, there was a tendency towards a higher incidence of seropositive in older animals. This study confirmed that FMDV is widespread in the Dhofar region. Furthermore, it is the first report of serotype A and an animal testing seropositive for O and A in the Sultanate of Oman.","PeriodicalId":32106,"journal":{"name":"Journal of Agricultural and Marine Sciences","volume":"18 1","pages":"31-35"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69288914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The camel has unique physiological characteristics, including a great tolerance to high and low tem- peratures, solar radiation, water scarcity, rough topography and poor vegetation. Camels are mostly produced under traditional systems on poor levels of nutrition and are mostly slaughtered at old ages after completing a career in work, racing or milk production. In general, camel carcasses contain about 57% muscle, 26% bone and 17% fat with fore-quarters (cranial to rib 13) significantly heavier than the hind halves. Camel lean meat contains about 78% water, 19% protein, 3% fat, and 1.2% ash with a small amount of intramuscular fat, which renders it a healthy food for growing human populations. The amino acid and mineral contents of camel meat are often higher than other meat animals, probably due to lower intramuscular fat levels. Camel meat has been processed into burgers, patties, sausages and shawarma to add value. Future research efforts need to focus on exploiting the potential of the camel as a source of meat through multidisciplinary research into efficient production systems and improved meat technology and marketing.","PeriodicalId":32106,"journal":{"name":"Journal of Agricultural and Marine Sciences","volume":"18 1","pages":"7-24"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69289178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Ministry of Regional Municipalities and Water Resources (MRMWR) reported more than 1,000 dried-up Aflaj out of 4,112 in 1996. This paper presents an estimation of the damage caused to the rural communities due to Aflaj dry-up. The production function method and the cost based method are used to estimate the direct losses incurred by farmers and the local communities. These are related to (1) losses in marketed agricultural products, (2) increase in domestic water expenditures per household and (3) capital losses related to changes in house and land values. The study considered 33 dried-up Aflaj among the 1029 monitored by the MRMWR. Our results show that on average each family in the dried-up Falaj has lost an income equivalent of O.R 320 per month. This highlights the importance of Aflaj as an income generator in the remote rural areas. Live Aflaj provide fresh vegetables and healthy food as well as drinking water to the rural population without the need for governmental intervention. The contribution of the supporting wells, whenever provided by the MRMWR, is estimated at O.R 1,478 per family per year. On average the annual financial loss per family due to dry-up is estimated at O.R 3,301 per year. The total damage cost of dried-up Aflaj, at the Sultanate level, is estimated at more than O.R 59 million per year.","PeriodicalId":32106,"journal":{"name":"Journal of Agricultural and Marine Sciences","volume":"17 1","pages":"9-19"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69289128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the second experiment 45 lobsters were reared from an initial length of 45.4±4.6 mm CL and weight of 118.9 g to a length 66.0±7.1 mm CL and a weight of 304.1 g over 335 days. Total length increment was 45.8% and weight increment 155.1%. The daily food ration was 3.0-8.8%. The survival rate in the first experiment was 92.9%, in the second experiment it was also high (86.7%) during the first six months. In both experiments males grew faster than females. While the water temperature, pH, salinity and dissolved oxygen reflected the ambient condition of the Arabian Sea, these were not optimal levels for lobsters culture. The salinity was higher (37.5 ppt), while the water temperature was low (<20 o C) during the summer monsoon. The study demonstrated the possibility of cultivating sub-adult lobsters in Oman from 40 – 45 mm CL and 100 g to maturity stage, obtaining the legal size of 70 mm CL and a weight of about 350 g over a year.

Half of the tunnel base was used as a flat plate air heating solar collector and the other half as a dryer. The drying air was forced from the collector region (South side) to the drying region (North side) of the half circled tunnel where the product is to be dried. The drying temperature could be easily raised by some 5-30 oC above the ambient temperature inside the tunnel at an air velocity of approximately 0.5 m/sec. The test was conducted with 190.2 kg freshly harvested dates with initial moisture content of 32.8% (wet-basis) to analyze the performance of the dryer. The dates were dried to a final average moisture content of 18.6% (wet-basis) within two days (20 hours). The results indicated that the drying was faster in a solar tunnel dryer than the natural open air sun drying. It was possible to reach the moisture content level for safe storage within less than two days (20 hrs) with a solar tunnel dryer and 5-7 days in open air natural sun drying. The improvement in the quality of dates in terms of color and brightness was distinctly recognized.","PeriodicalId":32106,"journal":{"name":"Journal of Agricultural and Marine Sciences","volume":"17 1","pages":"21-31"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69288823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
