The objective of this study was to compare periparturient serum Ca dynamics (CaDyn) in cows with and without diseases early lactation. enrolled 1,949 from a commercial dairy farm northern Germany. Blood samples were drawn 7 d before expected calving date on 0, 1, 3, after analyzed for concentration. Cows monitored clinical hypocalcemia (CH), ketosis, left displaced abomasum (LDA), retained plac...

BACKGROUND Prophylactic measures are key components of dairy herd mastitis control programs, but some are only relevant in specific housing systems. To assess the association between management practices and mastitis incidence, data collected in 2011 by a survey among 979 randomly selected Swiss dairy farms, and information from the regular test day recordings from 680 of these farms was analyz...

This paper describes the methods and results of the Norwegian Mastitis Control Program implemented in 1982. The program has formed an integral part of the Norwegian Cattle Health Services (NCHS) since 1995. The NCHS also have specific programs for milk fever, ketosis, reproduction and calf diseases. The goal of the program is to improve udder health by keeping the bulk milk somatic cell count (...

In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first experiment, this was deposited into the duct of teats with orf (Group A, n=5) or papilloma (Group B, n=3). In the second, teats were chapped and then, the organism was deposite...

The incidence of clinical mastitis and infection status at calving was assessed in quarters treated with 1 of 2 internal teat sealants at the time of dry off. Two contralateral quarters per cow (n=63 cows) were treated with a sealant that contained 0.5% chlorhexidine; the other quarters were treated with a commercial teat sealant. Ten cows were untreated (controls). On d 2, 4, and 16 after dry ...

Knowledge of the efficacy of an intervention for disease control on an individual farm is essential to make good decisions on preventive healthcare, but the uncertainty in outcome associated with undertaking a specific control strategy has rarely been considered in veterinary medicine. The purpose of this research was to explore the uncertainty in change in disease incidence and financial benef...

Staphylococcus aureus is the most frequently isolated pathogen from bovine mastitis including subclinical, clinical, and chronic infections. Virulence factors possessed by S. aid in causing infection inflammation producing toxins proteins, which are responsible for pathogenesis of disease. In current study out 51 animals presented with clinical mastitis, was milk 18 animals. confirmed genus spe...

Lactation mastitis is a common, but poorly understood, inflammatory breast disease that is a significant health burden. A better understanding of the aetiology of mastitis is urgently required, and will assist in the development of improved prevention and treatment strategies in both human and animal species. Studies in mice have the potential to greatly assist in identifying new drug candidate...

Idiopathic granulomatous mastitis is a rare condition of unknown aetiology, affecting women of childbearing age. Although many conditions mimic granulomatous mastitis, the cytologic pattern of epithelioid cells, multinucleated giant cells, neutrophils, macrophages and reactive epithelial cells, in absence of caseation necrosis and foam cells should prompt a diagnosis of granulomatous mastitis. ...
