B S T R A C T Objective: Our investigation was conducted to evaluate the incidence of umbilical pathologies and the result of related surgical interventions in Sicilian cattle. Study design: 320 (214 females, 106 males) cattle with umbilical lesions were collected, anesthetized, operated on and follow-up recorded. We evaluated the injury incidence rate. Population: The animals considered were: high productivity dairy cattle (Holstein Friesian and Brown Swiss); meat breeds (Charolaise and

... ne) and some crosses. Results: The highest injury rate was simple omphalocele, followed by purulent omphalitis. A high percentage was found in young cattle. Friesians are the most prone to navel diseases. The dairy breeds, compared to the meat breeds, and double aptitude and crosses, were the most affected. The most common was simple omphalocele, with a small hernial port (1 to 3 cm), while the rest was greater than 3 cm, with severe organs or complications. Methods: the most commonly used surgery was herniorraphy with autologous reinforcement, while classic su- tures and mesh sutures were used in the remaining cases. Follow-up demonstrated healing in most of the treated subjects. Conclusions: The study aimed to estimate some surgical clinical cases in Sicilian cattle. Most injuries are lower abdomen injuries, mostly simple or complicated umbilical hernias. Young dairy females were the most affected. Meaning/Impact: Radical surgery is the treatment of choice in the vast majority of symptomatic or asymptomatic umbilical diseases; moreover, the correct management and the choice of an appropriate surgical approach allow to obtain an effective treatment of the lesions. Simple summary: In cattle farm, the correct management of births is a fundamental step for the future of the breeding. In fact, there are numerous critical factors in this phase: calving area management, umbilical disin- fection, correct administration of colostrum, management of [...]
