Abstract

Present study was carried out in four crossbred jersey cows aged between 4-6 years. These cows were presented to the Teaching Veterinary Clinical Complex, RIVER with a history of difficulty in milking, presence of palpable foreign body in the teat canal and pain on palpation of the affected teat. Ultrasound scanning using 7.5 MHz linear probe by water bath method confirmed the presence of foreign body in the teat canal. Under sedation and local analgesia, the foreign bodies were retrieved instrumentally under ultrasound guidance in case 1 and 2, through thelotomy in case 3 by making incision on the teat at the site of obstruction and by theloscopic electroresection and thelotomy in case 4 by theloresectoscope. Collagen based Silver sulfadiazine cream was applied over the thelotomy site. Systemic administration of Inj. Streptopenicillin and intramammary infusion through the prosthetic tube kept in-situ and systemic antibiotic were followed for 5 days in case 3 and 4. All the cows recovered uneventfully. Foreign bodies recovered in this study were teat siphon, AI sheath and AI straw. Keyword: Teat, Foreign body, AI sheath.
