Vaccination for bacteria which causes mastitis is a practice can be applied in well managed herds but do not hope miracle from vaccination. Hygiene, feeding and proper milking procedures with a good farm management are the key factors for the reduction of mastitis in dairy farms

I agree, vaccination as all the tools to control mastitis is not the single solution to solve all the problems. But Mastitis vaccination is good tool to improve your mastitis control programme. If you use good management practices and at the same time you improve your immunitary status with high quality mastitis vaccines you will obtain the best results in the farm, we can say that doing that, 1+1=3.

Hi Everybody, To adopt control measures for any disease it is essential to first know the basic cause of the ailment. In this case the ailment is mastitis in bovines and vaccination for its control. We have emphasized many a times in our comments and our paper in this Forum " Pathobiology,etiology and treatment of mastitis.." that MASTITIS in lactating animals, in general, is not an infectious disease but a metabolic problem. In this study by Roger et al (this one) while delving into their observations of control of mastitis in bovines we find that they collected 39,506 milk samples in all and 29439 were culturally negative, 2123 were missing or contaminated and 799 were blind quarters. Moreover, there were about 22 infectious organisms identified by them in these milk samples. Usually the protection of vaccine is species/strain specific, therefore, the MODERATE control by this vaccine has been viewed by many other studies to be re-evaluated on larger population before its adoption in the field.
