Abstract
The present disclosure relates generally to sol-gel polymer composites that comprise chitosan, a hydrophilic polymer, a polysiloxane, and a gelation agent in a suitable medium. Advantageously, the sol-gel polymer composite can form a durable seal or strong solid in response to one or more physiological stimulus. The disclosure further relates to medical and veterinary uses of the composite, particularly, methods and delivery systems for reducing or preventing the incidence of a mammary disorder in a dairy animal. More particularly, the disclosure includes methods and sol-gel polymer composite compositions for creating a physical barrier on the teat surface or in the teat canal or cistern of a non-human animal for prophylactic treatment of mammary disorders such as mastitis wherein the sol-gel polymer creates a seal in response to one or more physiological stimulus.
