ABSTRACT
The efficacy of 2 teat dips, product 1 (Della Care with 5 to 8 ppm of free iodine, used as a positive control) and product 2 (New Della Care with 12 to 16 ppm of free iodine), was compared using a natural exposure trial on dairy cattle. The trial was based on National Mastitis Council guidelines and performed over 9 mo. Both teat dips contained 0.25% iodine. Product 2 reduced the infection rate 57.6% for major pathogens and 53.7% for minor pathogens, compared with the positive control. Product 2 gave highly significant reductions for Staphylococcus aureus, coagulase-negative staphylococci, and Corynebacterium bovis. Teat skin, teat ends, and teat hyperkeratosis were evaluated during trial. No significant difference in teat condition was observed between these 2 products.

An experimental challenge trial was performed according to the guidelines recommended by the National Mastitis Council (NMC). A 0.1% iodine teat dip (Quartermate with I-Tech) was examined. This product gave an 87.9% reduction of new intramammary infections with Staphylococcus aureus and a 66.5% reduction for Streptococcus agalactiae compared with a negative control. Teat end and teat skin characteristics remained excellent throughout the trial.

An experimental challenge trial was performed against Staphylococcus aureus and Streptococcus agalactiae following the procedures recommended by the National Mastitis Council. The efficacy of two teat dips, product 1 (Bovadine with I-Tech II) and product 2 (Bovadine with I-Tech, used as a positive control), was determined. Both teat dips contain 1% iodine and 10% glycerin. Product 1 established an 89.7% reduction in infections against Staph. aureus and 73.1% reduction in infections against Strep. agalactiae. Product 2 demonstrated an 86.2% reduction in infections against Staph. aureus and 78.4% reduction in infections against Strep. agalactiae. Teat skin and teat ends were evaluated before and after the trial. No significant change in teat condition was observed for either product.
