Changes in milk composition as affected by subclinical mastitis in sheep.
The mechanism of the effects of glandular-level subclinical mastitis in dairy sheep on milk yield and on its composition as expressed in curd yield was studied. Thirty-six Israeli-Assaf dairy sheep with one udder half infected with identified coagulase-negative staphylococci and the contralateral gland free of bacteria were chosen. The milk yield of the infected halves was significantly lower t...
متن کاملChanges in milk composition as affected by subclinical mastitis in sheep and goats
The present study focused on gaining a better insight into how subclinical mastitis at the gland level in dairy sheep and goats affects milk yield and compositional changes in relation to curd yield. Animals chosen for the study had one udder half infected with identified coagulase-negative staphyloccocci (CNS) species and the contra-lateral gland was free of bacteria. Udder halves were tested ...
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...
متن کاملFractionized milk composition in dairy cows with subclinical mastitis
Mastitis is the inflammatory reaction of the udder to invading pathogens. One of the most apparent reactions is the increased influx of immunoreactive cells from blood into milk inducing a dramatic increase of milk somatic cell counts (SCC). We have investigated (i) the relationship between log SCC/ml in infected quarters being >6 (n = 8, group I) or varying between 5.4 and 6 (n = 8, group II) ...
متن کاملDrug resistance in isolated bacteria from milk of sheep and goats with subclinical mastitis in Shahrekord district
Four-hundred milk samples from half udders of 20 flocks of native breed goats were asepticallycollected. The samples were examined by California mastitis test (CMT). Twenty-one (5.25%) of 400 wereCMT-positive. The CMT-positive samples were then cultured and the following bacteria were isolated:Staphylococcus aureus in 3 (14.28%), CNS (coagulase-negative staphylococci) in 14 (66.66%), streptococ...
