The aim of this study was to describe the arterial supply of the uterine-fetoplacental complex in alpacas during gestation. In total, 26 female alpacas were used; of these, 5 non-pregnant females were used to describe the irrigation of the reproductive tract and the origins of its irrigation; and 21 pregnant females were distributed in subgroups of 7 and slaughtered when they reached the 1st, 2nd and 3rd third of gestation, respectively. The specimens were processed using the filling-corrosion technique. Observation of uterine irrigation in pregnant and non-gravid uteri shows that it originates from the abdominal aorta artery, from where the ovarian arteries emerge, which pass towards the ovaries and from where they continue through the cranial uterine arteries and enter the uterine horns where they anastomose with the lateral and ventral branches of the caudal uterine arteries that take...

Se puede mejorar las características seminales en alpacas usando hormonas exógenas, para lo cual se evaluó los efectos de la GnRH y Oxitocina sobre las características seminales y concentraciones séricas de testosterona en alpacas. El trabajo se realizó en el CIP Quimsachata y en el Laboratorio de Reproducción Animal de la FMV-UNMSM- Lima, utilizando 10 machos para colecciones seminales post aplicación de 50 µg de acetato de buserelina (GI), 50 Ul de oxitocina (Gil) y 50 µg de acetato de buserelina + 50 Ul de oxitocina (GIII), y 12 machos para determinación hormonal. Se evaluaron: volumen, color, aspecto, pH, concentración, vitalidad, motilidad, endosmosis y anormalidades, se obtuvo 3 mL de sangre post aplicación hasta los 135 minutos, se obtuvo suero sanguíneo y se valoró testosterona por RIA. Los resultados fueron: volumen (1.77, 1.97, 1.07, 2.92 mL); pH (7.657, 8.017, 8...

Hippocamelus antisensis (d'Orbigny 1834), commonly called taruca, is a deer that lives in Peru, Bolivia and Chile between 3500 to 5000 m, and is considered a vulnerable species. The axial skeleton of the taruca is described based on four specimens (two males and two females), according to authorization RDG N° 158-2015-SERFOR-DGGSPFFS. The bone pieces were obtained according to the anatomical technique, the description is in accordance with the Veterinary Anatomical List and the measurements as described by Von den Driesch. In the skull, the occipital does not have a very prominent occipital protrusion, the frontal bone is characterized by its horn process and by presenting up to three supraorbital foramina, the lacrimal has a deep fossa and a fissure covered by cartilage, the incisor bone and maxilla are elongated, in the maxilla there is the presence of a dental socket for the canine, ...
