RESUMEN El bienestar de los animales terrestres describe las expectativas de la sociedad sobre las condiciones que los animales deberían experimentar cuando están bajo el control humano. Estos principios incluyen que los animales deben estar libres de dolor, lesiones y enfermedades. La inflamación es el mecanismo de defensa de un huésped contra una infección bacteriana o viral, o una lesión física o química al huésped. Los metabolitos secundarios de las plantas son una alternativa eficaz para el tratamiento de enfermedades inflamatorias. El propósito de esta investigación fue evaluar la capacidad antiinflamatoria de un extracto hidroalcohólico de hojas de Salix babylonica (HESB) empleando el modelo de edema auricular inducido por TPA en ratones. El HESB mostró una buena actividad antiinflamatoria sin diferencia estadística significativa con el fármaco de referencia, indometacina. Por este motivo, se realizó una bipartición de HESB, obteniendo una fracción acuosa (AFSB) con actividad farmacológica leve (30.64 ± 3.03 %) y una fracción orgánica (EAFSB) que mostró el mejor efecto antiinflamatorio (67.08 ± 7.15 %). Anteriormente, identificamos los flavonoides antiinflamatorios luteolina y luteolosido como los componentes principales de EAFSB, por lo que el efecto antiinflamatorio de Salix babylonica puede ser atribuido a estos compuestos. Además, el análisis histopatológico mostró que las orejas de los ratones tratados con Salix babylonica suprimieron la infiltración de neutrófilos en el sitio de inflamación. Estos resultados apoyan el uso etnomédico de esta planta y evidencian el posible uso de Salix babylonica en el tratamiento del proceso inflamatorio en animales.

ABSTRACT The wellbeing of terrestrial animals describes society’s expectations for the conditions animals should experience when under human control. These principles include that animals must be free from pain, injury and disease. Inflammation is a host’s defensive mechanism against bacterial or viral infection and physical or chemical stimulus to the host. Metabolites from plants are an efficient alternative for treatment of inflammatory diseases. The purpose of this research was to evaluate the anti-inflammatory capacity of a hydro-alcoholic extract from Salix babylonica leaves (HESB) employing the auricular edema induced by the TPA model in mice. The HESB showed good anti-inflammatory activity without significant difference from the reference drug, indomethacin. For this reason, a bipartition of HESB was conducted, obtaining an aqueous fraction (AFSB) with slight activity (30.64 ± 3.03 %) and an organic fraction (EAFSB), which showed the best anti-inflammatory effect (67.08 ± 7.15 %). Previously, we identified anti-inflammatory flavonoids luteolin and luteoloside as the major components of EAFSB. In addition, histopathological analysis showed that mouse ears treated with Salix babylonica suppressed neutrophil infiltration into the inflammation site. These results support the ethno-medical use of this plant and evidenced that Salix babylonica’s applicability and value as an anti-inflammatory treatment for animals.

ABSTRACT The objective of this study was to evaluate the effects of ginger as an additive in the diet of fattening rabbits. Sixty weaned rabbits (35 days old) were randomly assigned to four groups (n = 15). Animals were fed ad libitum with a control diet or one of three experimental diets supplemented with 0.5, 1, and 2 g of ginger per 100 g of feed during 28 d. Weight gain in the final week of the experiment was significantly greater in rabbits fed ginger at 0.5 g/100 g of feed than in those fed ginger at 1 and 2 g/100 g of feed or the control diet. No significant differences in morphometric measurements were observed among the treatments, but higher values of live weight, carcass length, and carcass circumference were observed in rabbits treated with ginger than in those fed the control diet. Regarding carcass quality parameters involving the kidneys and empty gastrointestinal tract, we found that rabbits treated with ginger at 0.5 g/100 g of feed showed significant differences from those treated with ginger at 1 and 2 g/100 g of feed or the control diet. pH, water holding capacity, L*, and a* did not significantly differ among the treatments, although greater water holding capacity was observed in rabbits treated with ginger than in control rabbits. Parameter b* was significantly higher in rabbits fed ginger at 2 g/100 g of feed than in those fed at 0.5 and 1 g/100 g of feed and in the control. The results found suggest that ginger can be used as an additive in diets of fattening rabbits.

ABSTRACT: The present report describes a schwannoma type III found in a 12-year-old male SharPei dog, this neoplasm was excised and analyzed using histopathological and immunohistochemistry examinations. This schwannoma was classified as high malignancy and presented metastasis to the axillary node. A secondary bacterial septicemia was identified with routine and molecular techniques. The Inmunohistochemical diagnosis of the mass, corroborated the presumptive diagnosis, which suggested a Schwannoma as well as its malignancy degree. In addition, Leucobacter chromiiresistens was isolated, a specie of which to date there are no reports as a pathogen in animals or humans.

RESUMEN: El presente reporte describe un schwannoma tipo III encontrado en un macho SharPei de 12 años, la neoplasia fue retirada y analizada por histopatología e inmunohistoquímica. El schwannoma fue clasificado con alta malignidad y con metástasis al linfonodo axilar. Con técnicas de rutina y moleculares se identificó una septicemia bacteriana secundaria. El diagnostico inmunohistoquímico confirmó el diagnóstico presuntivo de schwannoma, así como su grado de malignidad. Adicionalmente se aisló e identificó Leucobacter chromiiresistens, especie de la cual a la fecha no hay reportes como patógeno de animales o humanos.

Resumen: Se evaluó el uso de Dalbergia Palo-escrito, como curtiente natural de piel de conejo. Se realizaron dos ensayos con extractos acuosos de Dalbergia palo-escrito, para el primero se utilizó hoja y tallo, para el segundo solo se utilizó tallo a concentración de 20, 40 y 60 g L-1, se realizó el curtido de piel de conejo y se evaluó color, textura y propiedades físicas de la piel. Al utilizar extracto de hoja y 60 g L-1 de tallo disminuyó la luminosidad (P < 0.05). Las pérdidas de peso de la piel, firmeza y fracturabilidad se incrementaron con 40 g L-1; y con 20, 40 y 60 g L-1 las pérdidas de área y la proporción de tamaño disminuyeron, e incrementó suavidad, brillo y firmeza. Las pieles de conejo curtidas con extractos de Dalbergia palo-escrito a concentración de 40 g L-1, presentaron mejor calidad física.

Abstract: Evaluate the Dalbergia palo-escrito, as a natural tanning agent for rabbit skin. Two tests were carried out with extracts of D. palo-escrito, for the first, with leaf and stem, for the second the stem at different concentrations (20, 40 and 60 g L-1). With the extract, it carried out the tanning of rabbit skin, to evaluate color, texture and physical properties of the skin. The leaf and 60 g L-1 of stem extract decreased (P < 0.05) luminosity, while it did not affect the loss of weight and size of the skin. The loss of skin weight, firmness and fracturing increased with 40 g L-1; with 20, 40 and 60 g L-1 the loss of area and the proportion of size decreased, instead they increased softness, gloss and firmness. Concluded that the rabbit skins tanned with extracts of D. palo-escrito at a concentration of 40 g L-1, presented better physical quality.
