Efficacy of oxytetracycline and tetracycline-benzydamine in the prevention of infection after placental retention in cattle.

The efficacy of intrauterine oxytetracycline and a combination of benzydamine and tetracycline in preventing uterine infections in 150 Italian Friesian cows with retained placentas were compared. The animals were divided into three equal groups. Sixteen per cent of the oxytetracycline-treated group, 12 per cent of the benzydamine-tetracycline-treated group and 76 per cent of the untreated group developed endometritis. The difference between the two treatment groups was not significant but both treatments were effective in preventing septic complications in cows with retained placentas.
