Some biochemical Studies on Friesian Suffering from Subclinical Mastitis
نویسنده
چکیده
The present study was conducted to investigate the effect of subclinical mastitis on clinicopathological changes in Mastitic friesian. A total of 400 individual milk samples from clinically normal udder quarters of 100 diary friesians were examined microbiologically as well as by using California mastitis test (C.M.T.) for detection of subclinical mastitis and designing rapid diagnostic tests for other infection. Blood samples were analysed for hemogram, cortisol, alanine aminotransferase, asparate aminotransferase, total protein, inorganic phosphorous and calcium. Also L.DH in milk was detected. The results indicated that there is a significant elevation of cortisol, Sgot, p.cv, L.DH activity in milk while a notable decrease in total protein, serum calcium and Hemogram. was observed. However; Serum phosphorous level did not exhibit obvious changes. [Nature and Science. 2010;8(4):143-146]. (ISSN: 1545-0740).

متن کاملThe effect of subclinical mastitis on milk composition in dairy cows
Milk samples were collected from quarters of 35 cows with subclinical mastitis (California mastitis test [CMT] positive and somatic cell counts [SCC] >500,000 cells/ml in individual quarter foremilk), as well as from 37 healthy controls. Compared to the levels observed in milk from healthy quarters, milk from quarters with subclinical mastitis showed elevated sodium (91.97 vs 52.93 mg/dl), chlo...
