PURPOSE:To describe video-assisted ovariohysterectomy (OHE) with two portals access in adult intact queens. METHODS:Fifty-two females cats were used. A 4 mm cannula was positioned in the abdomen through an incision close to the umbilicus (first portal), and a pneumoperitoneum was established. A second portal was positioned in the midline of the pre-pubic region. Females were positioned in right lateral recumbency to locate the left ovarian pedicle, and the uterine horn was held by a transcutaneous suture.The pedicle was cauterized and incised. The procedure was then performed on the contralateral ovary. The ovaries were exteriorized from the abdomen, along with the uterus, through the second access point. The uterine body was exposed, fixed and sectioned, and the abdominal incisions were sutured. RESULTS:Surgeries were performed in an average of 41.4±14.2 minutes. The main complications included hypotension (7.7%) and subcutaneous emphysema (7.7%), and 13.5% of the surgeries were converted to laparotomy. CONCLUSION:Ovariohysterectomy using a video-assisted technique and two access portals is safe, has minimal risks and is effective for the spaying of queens.

The presence of the zona pellucida has been perceived as a requirement for the oviductal transfer of cloned embryos at early stages of development while protecting the embryo from an immune system response. We hypothesized that steroid hormone therapy could reduce a potential cellular immune response after the transfer of zona-free cloned embryos into the oviduct of recipient female goats. In Experiment 1, seven does were used to study the systemic immunosuppressant effect of the methylprednisolone administration (for 3 days) on blood cell counts. Whole blood was collected prior to treatment with methyprednisolone and then on Days 1, 2, 3, 4, 7, 14, 21 and 28 after the first dose of methylprednisolone for the analysis of haematological parameters. Methylprednisolone treatment significantly reduced circulating white blood cells and neutrophils in comparison with pre-treatment levels, demonstrating a systemic immunosuppressant effect. In Experiment 2, a group of 58 does were used as recipient females to study the effect of administration of methylprednisolone for 3 days on the establishment of pregnancies after the transfer of zona-free cloned embryos into the oviducts. No effects on pregnancy rates on Day 30 were observed regarding the distinct treatment groups (control vs. methylprednisolone), the source of oocytes (in vivo- vs in vitro-matured) or the presence or absence of the zona pellucida in embryos. In summary, methylprednisolone was effective at inducing a systemic immunosuppressed state in goats, but the treatment prior to embryo transfer did not affect pregnancy rates. Moreover, pregnancy rates were similar between zona-free and zona-intact goat cloned embryos.

ResumoNeste estudo, foi descrita a técnica de anestesia epidural em cutias nulíparas e não nulíparas submetidas à ovariossalpingohisterectomia. Roedores estes, pertencentes ao Zoológico Municipal de Catanduva, "Missina Palmeira Zancaner", São Paulo. A tranquilização foi obtida após a aplicação de azaperone (4mg/kg) e meperidina (4mg/kg) seguida da administração de cetamina (20mg/kg) e xilazina (0,4mg/kg), ambos na mesma seringa, para indução da anestesia e todos por via intramuscular. A seguir, foi aplicada lidocaína (5mg/kg) no espaço lombossacro. Foram avaliados o período de latência da associação anestésica (4,0±1,51min); período de latência da lidocaína epidural (6,87±2,35min); o tempo hábil de analgesia (115,0±12,49min); e a temperatura retal, a qual diminuiu, em média, 2,12±0,86°C desde o começo da anestesia até o final do período hábil de analgesia. Todos os animais se recuperaram de forma satisfatória, sem apresentar sinais de excitação e não foram observadas complicações decorrentes da técnica epidural. Concluiu-se que a técnica de anestesia balanceada empregada proporcionou analgesia adequada, durante tempo que seria suficiente para a realização de vários procedimentos, com a utilização de doses reduzidas de xilazina e cetamina.Unitermos: anestesia, cutia, Dasyprocta azarae, epidural AbstractEpidural anesthesia in agoutis (Dasyprocta azarae).

The objective of this study was to evaluate the forage-intake process of goats feeding on Massai grass pastures with different heights (40, 50, 60, and 70 cm). The experimental design was completely randomized, with treatments corresponding to four sward heights with two replicates over time and space. Collected data were related to the forage-intake process and the chemical and morphological composition of the pasture. Grazing trials (45 min) were performed with four Anglo-Nubian crossbred goats. Total forage mass intake, bite mass, and intake rate were expressed in relation to animal weight. Pasture density, forage mass, and leaf blade increased as forage height increased. The chemical composition of forage at the evaluated heights was similar, except for reduced crude protein content at 70-cm height. Bite rate, intake rate, and time per bite had a quadratic relationship with increasing sward height. The greatest intake rate was observed at 54.7 cm of height, with 0.136 g DM min -1 kg -1 LW. Bite rate exhibited a linear and positive correlation with increase in intake. At the 50-cm height, goats harvested a mass of 3.65 g DM bite -1 kg -1 LW, when they performed 34.5 bites per minute. Adult goats had a greater forage intake on 50-cm high Massai grass pastures because they could obtain a greater bite mass in a shorter time per bite. Key words: Bite mass. Bite rate. Intake rate. Intake. ResumoObjetivou-se avaliar os processos de ingestão de forragem por caprinos em pastagem com capimMassai manejado sob diferentes alturas (40, 50, 60 casualizado. Os tratamentos corresponderam a quatro alturas do dossel com duas repetições no tempo e no espaço. Os dados coletados foram relacionados aos processos de ingestão de forragem e composição química e morfológica do pasto. Foram realizados testes de pastejo de 45 minutos com quatro cabras mestiças da raça Anglonubiana. A massa de forragem total consumida, massa de bocados e a taxa de ingestão foram expressos em relação ao peso dos animais. Com o incremento da altura da forragem houve aumento na densidade do pasto, massa de forragem e lâmina foliar. A composição química da forragem nas alturas avaliadas foi semelhante, com exceção da redução do teor de proteína bruta aos 70 cm. A taxa de bocado, taxa de ingestão e tempo por bocado apresentou relação quadrática com o aumento da altura. A maior taxa de ingestão foi observada aos 54,7 cm de altura, com 0,136 g MS min -1 kg -1 de PC. A massa de bocado apresentou relação linear e positiva com o aumento da altura. Aos 50 cm as cabras colheram uma massa de 3,65 g MS bocado -1 kg -1 PC, quando realizavam 34,5 bocados por minuto. No pasto de capim-massai aos 50 cm ocorre maior consumo de forragem por cabras adultas, pois os animais conseguem obter uma massa maior do bocado em menor tempo por bocado. Palavras-chave: Consumo.

The effects splenic dilatation induced by acepromazine in a prospective, randomized study. Thirtythree adult mongrel dogs were divided into two groups designated as AG (acepromazine 0.05 mg/kg, i.v., n = 23) and CG (0.9% sodium chloride administered at a similar volume, n = 10). In both groups underwent sonographic examinations before (T0) and fifteen minutes (T15) after drug injection. The thickness spleen and splenic vein width were measured. Higher thickness was found in the AG group at T15 (2.47 cm) when compared to that at T0 (2.06 cm, p = 0.016), while the T0 (2.33 cm) and T15 (2.39 cm) measures did not differ within the CG group. Moreover, the splenic vein width was higher (p = 0.013) at T15 than at T0 in the AG group. Based on results of this study, we concluded that acepromazine, in doses of 0.05 mg/kg, promotes splenomegaly in dogs after fifteen minutes of the injection.Keywords: Canis lupus familiaris. Phenothiazines. Splenomegaly. ResumoForam avaliados os efeitos de dilatação esplênica induzidos pela acepromazina em estudo do tipo prospectivo e randomizado. Trinta e três cães foram distribuídos em dois grupos designados como GA (acepromazina 0,05 mg/kg, i.v., n = 23) e GC (solução de cloreto de sódio 0,9% em volume semelhante ao GA, i.v., n = 10). Em ambos os grupos foi realizada ultrassonografia abdominal previamente à aplicação das substâncias (T0) e após 15 minutos (T15). A espessura do baço e a largura da veia esplênica foram mensuradas. Foi verificada maior espessura esplênica no GA no T15 (2,47 cm) quando comparado a T0 (2,06 cm, p = 0,016), enquanto no GC não houve diferença significativa, sendo T0 (2,33 cm) e T15 (2,39 cm). Ainda, a largura da veia esplênica foi maior no T15 (p = 0,013) comparado a T0 no GA. Baseado nos resultados encontrados, pode-se concluir que a acepromazina na dose de 0,05 mg/kg induz a esplenomegalia em cães após 15 minutos da aplicação. Palavras-chave:Canis lupus familiaris.
