An ultrasonography was performed in 21 healthy male calves of Nellore (n = 8), Curraleiro Pe‐duro (n = 7) and Pantaneiro (n = 6) breeds, between 8 and 12 months, with the objective to display information about size, position and ultrasonographic parenchymal patterns of the liver, in addition to the topography of the gallbladder, right kidney and major vessels. The measurements used were dorsal margin distance (DMD) and ventral margin distance (VMD) of the liver, viewable extension (VE) of the liver, the caudal vena cava (CVC), width (CVCW) and depth (CVCD) and the portal vein (PV), width (PVW) and depth (PVD). The measures DMD, VMD and VE were similar, and the organ’s longest visible extension was in 11th ICS. CVC was more frequently observed in the 11th and 10th ICS, despite being visible from the 12th to the 9th ICS in Nellore and still 8th ICS in Curraleiro Pe‐duro and Pantaneiro. CVCD was lower in the 10th and 9th ICS in Nellore. The PV presented higher observation frequency in the 10th ICS. The measures PVD and PVW were higher in Nellore in the 11th, 10th and 9th ICS. To our knowledge, this report is the first to document ultrasonographic findings in three healthy calves. Considering the three breeds, the results show no differences in the ultrasonographic features as regard to the measurements and visualization of the position, size and vasculature of the liver and there was no additional information about the topography of the gallbladder and the right kidney.
Diseases of the external genitalia of the bulls cause important economic loss to livestock due to low breeding efficiency, treatment expenses and disposal of high zootechnical standards bulls. Some of these diseases can be treated surgically, allowing the bull to return to breading. Among these are phimosis, acropostitis, persistent penile frenulum, penile hematoma, penile deviation and penile fibropapillomatosis. Other surgical procedures performed in the reproductive tract of male bovines have zootechnical purposes, such as castration and teaser bulls' preparation. Penile amputation or penectomy is performed as a salvage method in bulls with urethral rupture. In the buiatric routine. ese surgical techniques are in relatively high demand and are generally performed in the field by the cattle practitioners. is review aims to describe the most common surgeries performed in the reproductive tract of male bovines addressing the anatomy, surgical techniques and post-operative care and complications.
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.
