The contribution of matrix metalloproteinases (MMP) to timely discharge of the placenta from bovine uterus at parturition is yet inconclusive, partly because of the presence of multiple MMP forms in situ. In the current study, the expression of different gelatinase subtypes on non-retaining placentas of Holstein cows was fingerprinted by using gelatin(More)
An appropriate length of milk stasis between two consecutive lactations of dairy cows is crucial for sustainable milk production. This dry period of cows allows extensive remodeling and sufficient cell renewal in mammary gland. Nevertheless, early dry period is one of the most risky stages in cow lactation cycle to intramammary infection. Dry-cow treatment(More)
Proper dry cow management is critical not only for subsequent milk production and fertility but also for mastitis control. A phenomenon of immunosuppression was commonly observed in transition cows, an example being the high susceptibility of the mammary gland during early the dry period to new infectious agents. Polymorphonuclear neutrophils (PMN) play(More)
A problem for dairy cows following milk stasis is to cope with a high risk of intramammary infection and there is a need to initiate an extensive renewal of secretory modules in mammary glands so that milk production in next lactation may be optimized. We recently reported that ultrasonicated Enterococcus faecium SF68 (SF68) is compatible with cow mammary(More)
Antibiotic dry-cow treatment contributes a major part to the total use of antibiotics in dairy herds. Enterococcus faecium strain SF68 (SF68) was of human origin but has been authorized in EU as probiotic feed additive. In the present study, one of the front and rear quarters of twelve late lactation Holstein-Friesian cows were infused once with a(More)
