Many farmers are using probiotics to help reduce antibiotic use for mastitis treatment. Chris Collier of Probiotic Revolution stumbled upon this breakthrough by chance. “One autumn I spotted a mob of lame cows by the cowshed of an organic farm and because there can be an association between acidosis and lameness, I suggested a 5-day treatment with a high dose of Calf Xtreme that had been used on calves. There were two mastitis cows in the group that also came right. Consequently, we formulated Bovine Boost to support cow’s natural immunity to health challenges. John McCarty who farms at Eltham, had good results with Bovine Boost on a small sample of 5 cows in 2018. Emboldened with these results John decided to use Bovine Boost instead of dry cow therapy at drying-o . “If we saw great results during the season, why wouldn’t it boost immunity to help a potential sub-clinical case at drying-o ” John explains. To make this simple and easy a separate mob was created for 5 days, and the dose was added to the water-trough twice daily. The only dry-period mastitis John got was in untreated low somatic cell count cows. “We monitored the treated cows closely the following season and there were no issues with them, so we’ve stuck to the probiotic approach since then.” Another important step in the journey to boost immunity to help health pre- calving is to add probiotics to a transition diet or as a trough treatment. “This time we are not just boosting immunity, but research suggest we are cutting down on sub-clinical ketosis.” Chris explains. “And research also points to an association between calving mastitis and ketosis.” Probiotic Revolution has formulated its products based on evidence that suggests they are stimulating cow’s appetites and reduced weight losses after calving. “Instrumentation on one farm in New Zealand using Probiotic Revolutions products showed an interval from calving to irst heats of as low as 24 days. This compares with a national average of 42 days. Probiotic Revolution has made some major modi ications to their milker supplement – Rumicell based on research done at Lincoln University and overseas trials. “We have always advocated the use of Rumicell to increase feed conversion e iciency, and the Lincoln trial showed us we had improved our product and allowed the price to come down to an a ordable 12 cents/cow/day. In addition to paying for itself in production farmers such as John McCarty are using it to support herd health and reduce antibiotic use.
