Which teat dip is best for your dairy? Seasonal changes, mastitis issues, sensitive teats, application methods, FDA regulations, residue in milk, and operator procedures are all a factor when choosing the correct teat dip. All Tetradyne® teat dips are registered with the FDA and we have a variety of products to meet your needs. Concentrates, non-iodine dips, 2 part dips, iodine dips, pre and post dips, and barrier dips from Tetradyne aid in the reduction of mastitis, when used properly, and can promote teat health. Neogen's hygiene representatives can recommend the best product for applications on your dairy.
