Heifers (n=1067 from 30 herds) were randomly allocated within herd to treatment in a 2 by 2 factorial arrangement approximately one month prepartum. The treatments were bismuth subnitrate teatsealent (Teat seal, Pfizer Animal Health, Auckland New Zealand) infused into all 4 glands (n=236), injection of 5 g of tylosin (Tylan 200, Elanco Animal Health, Manukau City, New Zealand) i.m. daily for 3 days (n=234), both teatsealent and tylosin (n=232), or no treatment (n=236). Milk samples were collected at enrolment, again at 0 to 4 d postpartum, and from glands with clinical mastitis. Data were analysed at the heifer level using logistic regression models.

Bacteria were isolated from one or more glands of 37% and 36% of the heifers, pre and postpartum, respectively. Treatment with teatsealent (RR = 0.38 (95% CI = 0.29-0.49), p < 0.001), but not tylosin (RR = 1.09 (95% CI = 0.88-1.32), p = 0.40) reduced the prevalence of infected heifers postpartum. Infection prepartum increased the risk of infection postpartum (RR = 1.66 (95% CI = 1.37-1.95), P<0.001).

The cumulative incidence of clinical mastitis over the first 2 weeks postpartum was 168/938 (17.9%). The cumulative incidence was reduced by teatsealent (RR=0.71 (95% CI=0.51-0.95), P=0.02), but not by tylosin (R=0.97 (95% CI=0.72-1.30), P=0.86). There were no tylosin by teatsealent interactions (P>0.2).

It is concluded that infusion of a teatsealent into all four glands of heifers precalving reduced the postpartum prevalence of infection and the incidence of clinical mastitis.
