The latest on-farm test designed to detect udder infections in dairy cows. UdderCheck measures Lactate Dehydrogenase (LDH), an enzyme present in milk when cells are damaged during an udderinfection. LDH is correlated to SCC, but is not easily affected by other conditions such as stress, nutrition, parity, stage of lactation, etc. LDH levels often rise earlier than somatic cell counts, making it an excellent marker for early detection of udder infections. No additional equipment is needed.
