Scientists tested Valiant Barrier and Valiant Pre\/Post for effectiveness against contagious and environmental pathogens. Since pre-dips are designed to help prevent environmental mastitis infections, Streptococcus uberis, an environmental bacteria, was used in both studies for Valiant Pre. Testing for contagious mastitis efficacy followed National Mastitis Council (NMC) Experimental Challenge protocol. In the absence of a NMC Experimental Challenge for environmental organisms, testing for environmental mastitis efficacy followed the NMC protocol for contagious Experimental Challenge as modified by Dr. Dave Galton, Cornell University.<\/p>\n<p><strong>What is an Experimental Challenge Study?<\/strong>\u00a0<br \/>\u00a0NMC protocol for Experimental Challenge studies call for challenging cows&#8217; teats with specific mastitis causing organisms. One-half of all teats are dipped with teat dip, the others are not dipped. Undipped teats serve as the control group. Weekly culturing detects the number of infections that occur in dipped versus undipped teats. Refer to the enclosed reports for specific information relating to the graphs below.<\/p>\n<p><strong>Valiant Testing Protocols<\/strong>\u00a0<br \/>\u00a0Experimental Challenge Contagious Bacteria: A set number of lactating dairy cows are determined free from infection prior to starting the multiple week tests. Following milking, all four teats of all test animals are submersed in a suspension of Staphylococcus aureus and Streptococcus agalactiae bacteria. Two teats are then dipped in the test product; the other teats are not dipped. Weekly quarter culturing identifies new infections during the test period.<\/p>\n<p><strong>Experimental Challenge Environmental Bacteria:<\/strong>\u00a0A set number of lactating dairy cows are determined free from infection prior to starting the multiple week test.\u00a0<br \/><strong>For Pre-Dip Testing:<\/strong>\u00a0one hour before milking, all four teats of test animals are submersed in a suspension of Streptococcus uberis bacteria. At milking, two teats are pre-dipped with the test product; the other teats are not pre-dipped.<\/p>\n<p><strong>For Post-Dip Testing:<\/strong>\u00a0after milking, two teats are post-dipped with the test product and the other two are not. One hour before milking, all four teats are submersed in a suspension of Streptococcus uberis bacteria.
