Detection of subclinical mastitis in dromedary camels (Camelus dromedaries) using somatic cell counts, california mastitis test and udder pathogen
A total of 120 quarter milk samples from 30 clinically healthy dromedary camel from Al-Jouf, Saudi Arabia were cultured to detect subclinical udder infection. The milk samples were screened by somatic cell count (SCC) and California mastitis test (CMT). Gram-positive cocci were the dominant recovered udder pathogen. The mean value of SCC was 125,000 cells/ mm. Infected quarter had generally hig...
متن کاملControl of Mastitis through dry cow therapy: A review
Introduction Mastitis is one of the most economically important diseases of milch animals and also causes the changes in glandular tissues affecting quality and quantity of milk [1]. Mastitis continues to be the most costly disease of dairy animals. Field surveys of major livestock diseases in Pakistan have ranked mastitis as number one disease of dairy animals [2,3]. In Nili-Ravi buffaloes, ma...
متن کاملSomatic Cell Counts of Cows with Recurrent Cases of Clinical Mastitis
Introduction Mastitis continues to be the most frequent and costly disease of dairy cattle. Financial losses due to mastitis occur for both subclinical and clinical stages of the disease. Losses caused by subclinical mastitis are well documented. Each doubling of SCC above 50,000 cells/ml results in a loss of 0.4 kg and 0.6 kg of milk per day in first lactation and older cows, respectively (Hor...
متن کاملSpatial patterns of recorded mastitis incidence and somatic cell counts in Swedish dairy cows: implications for surveillance.
Clinical mastitis (CM) is the most common veterinary treated disease in Swedish dairy cattle. To investigate if the distribution of veterinary registered cases of CM in Sweden follows that of the spatial distribution of cows with high somatic cell counts (SCCs), the spatial distribution of CM odds was estimated from available records and compared with udder health measures based on measurements...
متن کاملMastitis Prevention and Cure Rates in Heifers Treated with Spectramast Dry Cow Therapy and/or Orbeseal Dry Cow Teat Sealant
Dairy cows are vital for milk production, cheese, cream, and so much more. Healthy udders and teats are necessary to keep production levels at their highest and to keep the number of cows being culled to the lowest levels. Inflammation of the mammary gland is called mastitis, which is typically caused by bacteria that invade the teat canal. This disease is most often transmitted by contact with...
