Abstract Objective —To determine associations between rate of fistula formation and parity, lactation period, wound age, location, shape teat injuries in surgically treated teats dairy cows. Study Design —Prospective clinical study. Animals —106 lactating cows with lacerations. Procedures —Lacerations were classified via shape, age. Associations potential risk factors analyzed. Seasonal distribution, type injured teat, days determined. Results —Cows injury their first second parity had 4.1 times the odds formation, compared ≥ 3.Teats sutured within 48 to 72 hours 8.3 24 hours. Cows early stage (first 60 lactation) more susceptible injuries. Occurrence was greater at third, fourth, fifth parity. Conclusions Clinical Relevance —Season, period associated prevalence a range system. Neither suture material used nor suturing technique effects on healing operated full-thickness wounds. Factors such as age can be delay process, which may result formation.
