Dilatação e torção de ceco associada à obstrução por fitobezoar em bezerra / Cecal dilatation and torsion associated with phytobezoar obstruction in a heifer

Background: Dilatation of the cecum associated with intestinal torsion is a fermentative digestive disease that has a lowoccurrence in veterinary medicine, particularly in large animal practice. This condition is most prevalent in dairy cattle.The etiology of this digestive system disorder is related to changes in nutritional management. As it is an uncommoncondition that is frequently observed in the practice of veterinary medicine, the objective of this report was to describe acase of dilatation and torsion of the cecum associated with phytobezoar obstruction in a heifer that was examined at theVeterinary Hospital of the Federal Rural University of Pernambuco (HOVET-UFRPE), Recife, Brazil.Case: A 55-day-old heifer, with a history of abdominal distension associated with difficulty feeding and neurological signsof hind limb paresis, intentional head tremors, and prostration, was examined at the HOVET-UFRPE large animal clinic.A clinical examination demonstrated the presence of enophthalmos, abdominal distension, pale coloration of the ocularmucous membranes, and a moderate level of dehydration (3%). The dehydration was treated through the administrationof 1.150 L of saline solution along with 6 mL of Bionew (Vetnil®), 15 mL of calcium solution, and 5 mL of 50% glucose.Subsequently, the animal underwent intestinal washing through the insertion of an oral probe, which resulted in the expulsion of putrid content. Afterward, the animal’s blood was collected and sent to the Clinical Pathology Laboratory of theDepartment of Veterinary Medicine at HOVET-UFRPE for a complete blood count...

Análise comparativa do sistema reprodutor de vacas recém paridas por palpação transretal e ultrassonografia / Comparative analysis of newly calved cows by rectal palpation and ultrasound

tThis study aimed to compare the accuracy of two diagnostic methods, rectal palpation and transrectalultrasound of the ovaries, and assess the reliability of the diagnosis by palpation method. A total of sixteen (16)dairy farm cows underwent ultrasonographic examinations performed soon after rectal palpation. The accuracyof palpation may seem low, but when we analyze the data, we observed that the main structures diagnosed byultrasound were almost always diagnosed by palpation. Ultrasonography, however, has its strong point in theidentification of complex structures such as hemorrhagic body and follicular cysts. We conclude that ultrasoundas well as rectal palpation can be used as a diagnostic tool, although ultrasound provides good visualization ofovarian structures, allowing their measurement.(AU)

Emprego de protocolo longo à base de progesterona para sincronização do estro de novilhas e vacas Girolando / Use of long term progesterone protocol for estrus synchronization of Girolando heifers and cows

This study evaluated the efficacy of a long term progesterone protocols associated with PGF2a andGnRH by measurement of follicular diameter (FD) in D14, D22 and D30; time between the end of treatment andthe onset of estrus and conception rate in groups of Girolando heifers and Girolando cows (N1 and N2, V1 andV2). On D30, the diameter of FD for the groups V1, V2, N1 and N2 was 13.3 ± 0,11mm, 13.8 ± 0.14 mm, 0.10mm and 13.7 ± 12.7 ± 0.49mm respectively. The time between the end of the treatment and the onset of estrus forthe groups V1, V2, and N1, N2 was 115,2hs, 103,2hs, 127,2hs, 129,6hs, respectively. Based on the results it canbe concluded that the protocols were efficient for obtaining a dominant follicle in the PGF2a application dayfavoring a good conception rate.(AU)
