Development of an easy-to-adhere, hard-to-peel protective material for cow's teat

Updated:October 23, 2017 (Monday)

The Institute of Livestock and Grassland Science, NARO in collaboration with Tokuyama Co., Ltd. has successfully developed an easy-to-adhere and hard-to-peel seal-type material that can be used to protect the teat of cows for up to 2 weeks. It is expected that this protective material can be effective for efficient treatment of mastitis during the non-lactating period for dairy cattle.


  1. Mastitis is a major disease of dairy cattle due to inflammation of the mammary gland and udder tissue. The disease causes a decline in milk yield and quality and an estimated economic loss of 80 billion yen annually.
  2. A protective material made of liquid teat has been used to prevent new infections of mastitis during non-lactating period in dairy cattle. However, it takes time to perform pretreatment and drying after adhesion, and it usually drops out in a few days.
  3. NARO's Institute of Livestock and Grassland Science (NILGS) and Tokuyama Co., Ltd. conducted a joint research and developed a seal-type external teat protective material which is easy-to-adhere to the nipple and does not peel off easily.
  4. This external teat protective material can be used for up to 2 weeks after adhering to the nipple.
  5. This external teat protective material will be commercially available from November this year.
