Review highlights Georgian dairy sectored constraints such as usage of outdated practices and methods in cattle feeding, breeding, milking, and welfare. No control over veterinary medicine sales and usage. Food safety risks are connected to a lack of control of small household farmers. Researches done in the human health sector indicated antibiotic development resistance in Staphylococcus aureus , which is one of the familiar sources of bovine mastitis. Antibiotics resistance in dairy farming is not yet researched. However, National Food Agency monitoring results on the presence of prohibited antibiotics residual in cattle milk and blood indicates that there are increased risks of antibiotics resistance bacteria development in dairy farming and spreading in the environment through the food chain.","PeriodicalId":201427,"journal":{"name":"Journal of Dairy Research & Technology","volume":"90 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126120091","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}

Milk from 19 bulk production sites across Australia were collected on a monthly basis for 2-years in 1994-1995 and analysed for Fatty Acid (FA) composition. Considerable site and seasonal differences were encountered with the analysis revealing clear seasonal variation in the abundance of short chain saturated FAs, the minor unsaturated FAs, C16:0, and the long chain unsaturated FAs. The magnitude of difference varied with geography, with generally less variation observed in the Queensland, New South Wales and South Australian regions. Positive correlations were measured between the short chain FAs from C4 to C14, diminishing with the increased difference in chain length. Correlations between saturated and mono-unsaturated FAs of the same chain length were mostly positive for C16 and C18 however generally not for C10 and C14, indicating fundamental differences in desaturase activities for different carbon chain lengths and between regions. These results provide useful information that can be used by the Australian domestic and export dairy industry to understand and pre-dict the effect of season and geographical location within Australia on the abundance of FAs of nutritional importance.","PeriodicalId":201427,"journal":{"name":"Journal of Dairy Research & Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124239249","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}

Milk main traits, physical-chemical parameters, and fatty acid composition were measured, and data analyzed by descriptive statistics, mean comparison test and multivariate statistical analysis. An increase of proteins and fat was observed in summer, accompanied by a decrease of proteins/fat ratio. Milk urea showed higher levels in winter-spring (January-April). Rumenic acid, trans-vaccenic acid and linolenic acid decreased in late spring-summer (May-July). Somatic cell levels were found not correlated with the bacterial count, and their trend suggests a dependence to milk dilution. NaCl content compensated the lower levels of lactose in the summer season. Based on a big data set, results highlighted the main differences in bulk milk composition, over a long period of the year.

It can cause fever, hemorrhages, excessive salivation, agalactia, loss of body weight, abortion and occasionally death. A large outbreak of epizootic hemorrhagic disease virus serotype 6 (EHDV-6) was identified in several Israeli cattle farms towards the end of 2015. In this study, we examined the persistence of EHD-6 viral RNA circulation in whole blood (RNAmia) from six naturally infected sentinel calves. RNAmia duration was estimated based on real-time re-verse transcription polymerase chain reaction (RT-qPCR) of whole blood samples. Our results indicate that EHDV RNAmia lasted for approximately four months from the presumed date of the initial natural infection. Additionally, based on the data of PCR-positive field samples from sick animals and aborted cattle fetuses, along with isolated viruses from samples taken at the same period of time as a rou- tine diagnostic procedure, we conclude that the outbreak took place between late September and November 2015. Analysis of abortion cases throughout this period (all aborted fetuses and placentas tested for abortogenic pathogens), suggests that EHDV-6 was involved in the part of abortion cases in this cattle population. To our knowledge this is the first study of field monitoring of EHDV RNAmia, and first EHDV RNA detection in aborted fetuses. spp . was performed by inoculation of abomasal contents into Fry’s mycoplasma broth (Fre -undt, 1983) and platedonto mycoplasma agar.

J Res Tech 2: 008. Abstract Sudanese white cheese is a traditional pickled cheese to which 6-20% salt is added. Sudanese white cheese was made using three levels of milk fat: low fat (1%), partial skimmed (2%) and full fat (4%) milk. The produced cheese was packed into both glass and plastic containers and each were stored at room (38±2˚C) and refrigerator (5±3˚C) temperature. Salt, some minerals content and sensory eval uation were carried out every 2 weeks for a period of three months. The results revealed that Sudanese white cheese with the different fat levels were significantly (P<0.05) different in salt, sodium, calci um and phosphorous. Also the different types of packaging materials (glass and plastic) and storage duration showed significant (P<0.05) differences for salt content of the cheeses. The sensory evaluation was assayed for flavour, texture, appearance and the overall acceptability and showed significant (P<0.05) differences between the different types of cheeses. The cheese made using 2% milk fat kept in the glass containers and stored in refrigerator temperature gained the highest scores of organoleptic properties compared to other cheeses. The present study concluded that the cheese made with partially skimmed milk (2%) is better in its overall acceptability. This will suggest its introduction to the market and to convert the re-moved fat into other valuable dairy products (such as cream, butter and ghee). This will increase revenue for the producers and will give healthy images for the consumers who utilize such cheeses. The present study recommended further work in order to improve the acceptability of low fat cheese in Sudan.","PeriodicalId":201427,"journal":{"name":"Journal of Dairy Research & Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132086321","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 aim of this study was to evaluate the physicochemical characteristics of bovine, ovine and caprine milk, in Malta and Gozo, to define interspecies differences and determine possible differences between the two is -lands. 220 pooled milk samples were collected from farms in Malta and Gozo and analyzed for proximate parameters, using the Mas ter Pro milk analyzer. This study revealed minor differences in milk physicochemical characteristics between farms in Malta and Gozo however interspecies differences were significant (p<0.05). Statisti cal analysis revealed that ovine milk was highest in fats (6.56±1.72 %), solids-non-fat (10.47±0.69%), proteins (3.79±0.26%), lactose (5.65±0.37%) and salts (0.81±0.07 %) and had the lowest freezing point (-0.73±0.09°C). Principal component analysis revealed cor relations (r>0.974) between proteins, lactose, solids-non-fat and salts demonstrating that these variables are directly proportional with each other but are inversely proportional to the freezing point (r<-0.941). Principal component analysis also displayed distinctive characteristics for ovine milk. Due to the distinctive interspecies differences, this study may serve as a basis to distinguish the milk types by their physicochemical constitution. Subsequently, the trace ability of the milk type can be achieved on this basis.","PeriodicalId":201427,"journal":{"name":"Journal of Dairy Research & Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131675846","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}
