Teat burns in dairy cattle--the prognosis and effect of treatment.
Twenty cows and 20 uncalved 20 month old heifers with severely burnt teats were studied. Ten of each group received topical treatment with a mixture of lanoline, cetrimide and dimethyl sulphoxide or vitamin A and petroleum jelly, respectively. Prognosis for survival and future normal milking ability was poor in heifers (8 subsequently normal of 20 assessed) but moderate in cows (9 cows with normal and 5 cows with partial machine milking ability of 18 cows fully assessed). Treatment did not significantly increase the rate of epithelialisation of wounds. Topical treatment had no effect on the prognosis of heifers. However treated cows were more likely than control cows to survive and to show adequate teat function following subsequent calving. Severe clinical mastitis prior to calving, teat distortion and teat canal constriction were common sequelae. Recommendations on the management of heifers and cows with severely burnt teats are made.
