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 کاملAlternative Use of Somatic Cell Counts in Genetic Selection for Mastitis Resistance
Various alternatives in analyzing somatic cell counts (SCC) as indirect indicator of resistance of mastitis are discussed by integrating knowledge of the dynamics of the infection and statistical methods used in quantitative genetics and epidemiological research. This is done by (1) defining various measures of SCC, (2) identifying non genetic factors of SCC variation, and (3) proposing a new a...
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 کاملUse of a Staphylococcus aureus vaccine to reduce prevalence of staphylococcal mastitis and lower somatic cell counts in a registered Saanen dairy goat herd
The purpose of this investigation was to evaluate the efficacy of a commercial bacterin (Lysigin ® ) in reducing the prevalence of staphylococcal intramammary infections (IMI) and lowering somatic cell counts (SCC) in a commercial dairy goat herd. Does were sampled over a 4-month period prior to vaccination to establish a baseline for the prevalence of mastitis, SCC, and bulk tank bacteria coun...
متن کاملUse of a staphylococcal vaccine to reduce prevalence of mastitis and lower somatic cell counts in a registered Saanen dairy goat herd.
This investigation evaluated the efficacy of a bacterin in reducing the prevalence of staphylococcal mastitis and somatic cell counts (SCC) in a dairy goat herd. Does were vaccinated or left as controls, and the levels of mastitis and SCC monitored over 18 months. Staphylococcus caprae (42.5%), S. xylosus (15.1%), and S. simulans (10.0%) were the predominant causes of intramammary infections (I...
