Therapeutic and prophylactic effect of prepartum antibiotic infusion in heifers.
Prepartum bacteriologic examination of secretions from 42 dairy heifers 12-14 weeks prepartum revealed a total of 24 Staphylococcus aureus infected quarters, 53 Staphylococcus species infected quarters, and 20 Streptococcus species infected quarters. Prepartum intramammary therapy of primigravid dairy heifers with two commercially available dry cow antibiotics (penicillin-novobiocin or cephapirin) resulted in cure rates of 94%, 97%, and 100% for S. aureus, Staphylococcus species, and Streptococcus species intramammary infections (IMI), respectively. No protective effect was observed for dry cow treatment of uninfected quarters of heifers for any of the antibiotic preparations. No antibiotic was detectable in heifer secretions collected at parturition indicating that antibiotic concentrations may have fallen below protective levels prior to parturition.
