Chapinal, N., Fitzpatrick, C. E., Leslie, K. E. and Wagner, S. A. 2014. Short Communication: Automated assessment of the effect of flunixin meglumine on rumination in dairy cows with endotoxin-induced mastitis. Can. J. Anim. Sci. 94: 21–25. The objective was to evaluate the use of rumination loggers to monitor the effect of flunixin meglumine on rumination in lactating dairy cows with endotoxin-induced clinical mastitis. Mastitis was induced in 13 cows by intramammary infusion of Escherichia coli lipopolysaccharide (LPS) into a rear quarter. Four hours later, seven cows received flunixin meglumine intravenously and six received a saline solution. Control cows ruminated less than treated cows 5–8 h and 11–12 h after LPS infusion, although they ruminated more 15–16 h after LPS infusion. Rumination loggers show promise as a practical on-farm tool to monitor the efficacy of anti-inflammatory therapy for clinical mastitis.

Mycoplasmas are an important and economically significant cause of mastitis in dairy cows in various parts of the world. The organisms are highly contagious, with the main reservoir of infection originating from cows with subclinical mastitis. In 1998 the 1st cases of bovine mastitis due to Mycoplasma bovis were diagnosed in Ardabil State, Iran. An investigation was carried out with the aim of establishing the extent of mycoplasma infections in dairy cows in Ardabil State. Milk samples obtained from 80 cows with clinical mastitis were cultured in the laboratory for the presence of mycoplasmas. Similarly, 48 bulk-tank milk samples were examined for the presence of mycoplasmas. A modified Hayflick broth was used to isolate the mycoplasmas and an immunoperoxidase test used for the species identification of the isolates. Mycoplasma bovis was isolated from 39 (48.75 %) of the clinical mastitis samples and from 48 of the bulk-tank milk samples tested. This indicated that mycoplasma udder infections were more prevalent in dairy cows in Ardabil State than previously thought.
