El objetivo del presente estudio fue evaluar el efecto de tres edades de rebrote y tres niveles de inclusión de harina de pisonay (Erythrina edulis) sobre el consumo y conversión alimenticia; la ganancia de peso, y el rendimiento de carcasa en el engorde de cuyes (Cavia porcellus). Se utilizó las hojas y los peciolos secados bajo sombra de árboles cosechados, y procesados mecánicamente a 2 mm de tamaño de partícula. Se utilizaron 120 cuyes machos mejorados, distribuidos en 10 tratamientos (3 edades de rebrote, tres niveles de inclusión de la harina y un grupo control con harina de alfalfa) durante 56 días. La ganancia de peso total y diaria, además de la conversión alimenticia tuvieron un comportamiento similar entre los tratamientos; el consumo del alimento fue menor con el tratamiento 8M30% (54.0 g/día) con respecto al CA20% (59.3 g/día) (p<0.05) y el rendimiento de carcasa fue mayor en 4M20% (73.5%) en comparación con la dieta control (71.1%) (p<0.05). El consumo del alimento (60.3 g/día) como la conversión alimenticia (5.3) fue mayor a los 12 meses de edad de rebrote (p<0.05) con respecto a los 4 y 8 meses que fueron similares entre sí. El rendimiento de carcasa fue similar (72%) con la inclusión de 10 y 20% y disminuyó (70.6%) con el 30% de harina de pisonay (p<0.05), . La harina de pisonay utilizado como insumo alimenticio para la elaboración de concentrado no afecta las características productivas en cuyes.

<p><span style="font-size: medium;">Os porquinhos da Índia, também conhecidos como cobaias, além de animais de estimação têm grande importância na área de pesquisa científica. Devido ao elevado crescimento populacional, os tutores buscam métodos de esterilização para esses animais. Por este motivo, deve-se buscar um protocolo anestésico adequado. O objetivo desse estudo é avaliar os efeitos tranquilizantes e analgésicos produzidos pela neuroleptoanalgesia (NLA), coma utilização de acepromazina 0,2% na dose de 0,1 mg/kg e Fentanil 0,05% na dose de 0,005 mg/kg, ambos os fármacos foram administrados pela via intramuscular (IM). O protocolo empregado é considerado satisfatório para intervenções pouco invasivas como a Orquiectomia, além de avaliado como seguro para animais hígidos da espécie avaliada.</span></p>

A 2-year-old male guinea pig (Cavia porcellus) presented with a pea-sized swelling on his right labium. The tumour was excised and reconstructive surgery was performed using a single pedicle advancement flap, leaving the bottom of the lip intact on account of it being essential for food apprehension and manipulation. Two parallel skin incisions were made in the rostrocaudal direction for almost half the length of the head and the resulting skin flap was carefully undermined, to avoid damaging the follicles and the muscles of the whiskers. The flap was carefully sutured over the excisional defect and at 1.5 months post-surgery, only a small residual scar remains. The lips are intact, the surgical site is covered with fur and many of the whiskers have regrown. Histopathology showed the excised mass to be a grade 1 soft tissue sarcoma, most likely a malignant peripheral nerve sheath tumour.

Background: Excessive sun exposure results in increased activity of the tyrosinase enzyme and the amount of melanin in the skin which causes hyperpigmentation, a sign of premature aging. The purpose of this study was to prove that Ashitaba (Angelica keiskei) leaves extract cream 8% inhibited the increase of melanin and tyrosinase enzymes as effective as hydroquinone cream 4% in the ultraviolet B-exposed guinea pig (Cavia porcellus) skin. Methods: This study used a randomized post-test only control group design. The subjects were 36 male guinea pigs (Cavia porcellus). Subjects were divided into two groups, the hydroquinone cream 4% group and the Ashitaba leaves extract cream 8% group exposed to UVB light. Skin samples were collected 48 hours after the last exposure to measure the tyrosinase enzyme levels using the ELISA method and the amount of melanin was examined by Masson-Fontana staining. Results: The mean levels of tyrosinase in the hydroquinone cream 4% group was 19.51 ± 5.16 ng/L and the Ashitaba leaves extract cream 8% group was 23.76 ± 3.09 ng/L (p = 0.005). The mean amount of melanin in the  hydroquinone cream 4% group was 2.98 ± 2.27% and the Ashitaba leaves extract cream 8% group was 4.77 ± 3.33% (p = 0.069). Conclusion: The administration of Ashitaba (Angelica keiskei) leaves extract cream 8% inhibited the increase of melanin amount as effective as hydroquinone cream 4% and inhibited the increase of tyrosinase enzymes not as effective as hydroquinone cream 4% in the ultraviolet B-exposed guinea pig (Cavia porcellus) skin.
