The study evaluated the effect of the energy supplementation on the optimal culling age of guinea pigs (Cavia porcellus) in the Peruvian highlands. Two hundred guinea pigs of 4 weeks old were distributed in fours treatments during 13 weeks: forage ad libitum (T0), forage ad libitum plus 10 g barley grain/animal (T1), forage ad libitum plus 7 g sunflower seed/animal (T2), and forage ad libitum plus 5 g barley grain and 3.5 g sunflower seed/animal (T3). A randomized complete block design, with initial live weight defining the block, and 5 experimental units of 10 animals each, was applied. The energy supplementation improved body weight gain and feed conversion index (p<0.05), whereas the combination of sunflower seed and barley grain had an additional effect on body weight gain (T3) and the inclusion of sunflower (T2) on feed conversion index (p<0.05). The energy supplementation had...

El estudio evaluó el efecto de la suplementación energética sobre el momento óptimo económico de beneficio de cuyes en la Sierra peruana. Se utilizaron 200 cuyes machos de 4 semanas de edad, distribuidos en cuatro tratamientos por 13 semanas: forraje ad libitum (T0), forraje ad libitum más 10 g de cebada grano/animal (T1), forraje ad libitum más 7 g de semilla de girasol/animal (T2), y forraje ad libitum más 5 g de cebada grano y 3.5 g de semilla de girasol/animal (T3). Se empleó un diseño de bloques completos al azar, con el peso inicial como bloque, y 5 unidades experimentales de 10 animales por unidad. La suplementación energética mejoró significativamente la ganancia de peso y la conversión alimenticia (p<0.05); donde la combinación de granos girasol y cebada (T3) tienen un efecto adicional sobre la ganancia de peso, y la inclusión de girasol (T2) sobre la conversi...

It is described the clinical case of a canine patient attended 30 minutes after a car accident, with a luxofracture of the thoracic vertebra 12 and its surgical treatment by a technique of segmental fixation of the thoracic vertebrae 11, 12 13 and lumbar 1, using a Steinmann nail and surgical wires. The patient presented with paraplegia and little response to the deep pain stimulus, which, in less than 24 hours after the first evaluation was null. This demonstrated the rapid deterioration of the medullary functions detectable in the clinical examination; however, the rapid action and the diagnostic images allowed the execution of the surgical technique before 24 hours after the injury. The patient recovered his posture and the march three days after surgery, managing to walk seven days after the intervention. These results confirm the need for a timely neurological evaluation with diagno...
