Short- and Long-Term Production Losses and Repeatability of Clinical Mastitis in Dairy Cattle
clinical mastitis production repeatability
2008/8/6
Between 1985 and 1990, a study of 5313 lactations of 2477 Black and White cows was carried out. A stepwise least squares method was used to obtain unbiased estimates of milk, fat, and protein losses t...
The Effects of Early Antibiotic Treatment Following Diagnosis of Mastitis Detected by a Change in the Electrical Conductivity of Milk
Staphylococcus aureus Streptococcus uberis intramammary treatment somatic cell count
2008/7/15
Mastitis was induced experimentally by infusion of Streptococcus uberis or Staphylococcus aureus into the mammary glands of lactating dairy cows. Clinical mastitis was identified when clots appeared i...
The Natural Food Grade Inhibitor, Lacticin 3147, Reduced the Incidence of Mastitis After Experimental Challenge with Streptococcus dysgalactiae in Nonlactating Dairy Cows
natural inhibitor bacteriocin mastitis
2008/7/7
Lacticin 3147 is a broad-spectrum bacteriocin produced by the food-grade organism Lactococcus lactis. Lacticin 3147 is active at a neutral pH and has been shown to be bactericidal to streptococci and ...
Therapy of Experimentally Induced Coliform Mastitis with a Propionibacterium acnes Product
coliform mastitis Propionibacterium acnes
2008/7/3
The efficacy of a Propionibacterium acnes product for treatment of coliform mastitis was evaluated following intramammary infusion of Escherichia coli. Ten cows were injected intravenously with a prod...
a-Tocopherol Concentrations in Milk and Plasma During Clinical Escherichia coli Mastitis
a-tocopherol mastitis Escherichia coli
2008/7/2
Eighteen cows were challenged by intramammary infusion with Escherichia coli 727 to determine the effects of acute clinical mastitis on -tocopherol concentrations in plasma and milk. Cows were fed die...
