Article history Colic syndrome is a condition of great importance in equine production, a syndrome considered to be complex and multifactorial in nature. In this way epidemiological studies have been acting to contribute to the identification of risk factors in the development of wind power. This study evaluated the clinical epidemiology of the colic syndrome according to race, gender, diagnosis, affected segment, therapeutic decision and outcome of the cases treated at the Veterinary Hospital "Dr Halim Atique", interior of São Paulo. The medical records of the animals assisted from January 2004 to July 2018, whose complaint was abdominal discomfort, were evaluated. Of the 535 animals, the most affected breed was the Quarter Horses (69.3%) followed by the Mangalarga (6.9%); females (53.1%) were more prone to the development of the syndrome. Compaction (28.8%), gastritis (11.8%), followed by gas distension (10.3%) were the most frequent changes; the affected segments being the stomach (21.9%), major colon (17.2%), and small intestine (15.7%). Clinical treatment (64.7%) was the most instituted and in the outcome of the cases, the discharge (77.4%) prevailed. The study presents data that can support epidemiological research in the area, assisting in the identification of causal and predictive factors for the colic syndrome.
This study evaluated the viability of Nellore cloned calves derived from somatic cell nuclear transfer (SCNT) and compare their viability with animals of the same breed derived from in vitro fertilization (IVF). Thus, two groups were formed. Group I (GI) consisted of 10 calves derived from SCNT and group II (GII) consisted of 10 calves derived from IVF. The differences detected between the groups were in the physical examination of the respiratory tract in GI, which represented the most common clinical-pathological disturbances. The Apgar index score indicated that 80% of GI animals were depressed and all had pale mucous membranes. Thus, anemia was reported in GI. In GII, this started at 12 h of life and was probably caused by an iron deficiency. Moreover, total calcium and ionized calcium levels were higher in GI immediately after birth. These alterations probably resulted in a high incidence of mortality in GI, reaching 90% of the calves, whereas mortality was only 20% for the calves in GII. In conclusion, cloned calves, which were derived from SCNT, had physiological and metabolic alterations after delivery, leading to a higher mortality rate during the perinatal period.
The objectives of this study were to demonstrate the lesions that affect athlete bulls and to correlate the disorders with weight, age, affected limb and region of the limb. The present study was accomplished using radiographic images of athletic rodeo bulls collected from the medical and surgical records of the large animal service at the veterinary hospital. Radiographic images were evaluated for 136 bulls that were taken care of at the Veterinary Hospital, ranging in age from 4 to 13 years, with an average weight of 800kg and proven prior physical activity through participation in rodeos. The chi-square or Fisher’s exact test was used to assess the association between the studied variables. It was observed that 71.6% of the bulls studied and suffering from lameness had radiographic lesions, predominantly in experienced animals. Enthesopathy in starter and experienced bulls, septic arthritis in starter bulls, and fractures and degenerative joint disease in experienced bulls were the most frequent radiographic lesions diagnosed. The region of limb where the majority of radiographic changes occurred was the digits. Risk factors and occurrence of diseases of the locomotor system in athletic bulls are similar to those in sport equines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
