Researchers at Cornell University’s quality milk production services lab have found that liner type — round versus square — impacts teat-end health. In a study involving 12 commercial dairies, half used round liners and the other half used square liners. When the researchers evaluated teat-end health by keratinization score, they found that herds using round liners had more teats with higher keratinization scores. The chart below shows the keratinization score by liner type.
