Objetivou-se avaliar o efeito do fornecimento de levedura seca (LS), levedura hidrolisada (LH) e mananoligossacarideos (MOS) da levedura Saccharomyces cerevisae para leitões desmamados, medindo-se o desempenho zootécnico e parâmetros bioquímicos. Foram utilizados 144 leitões com 25 a 70 dias de idade, distribuídos aleatoriamente em quatro tratamentos (T), com seis repetições, sendo: T1- ração sem adição de leveduras; T2- pré-inicial I (0,02% LH), pré-inicial II (0,02% LH), inicial I (0,005% LH), inicial II (0,005% LH); T3- pré-inicial I (0,01% LH), pré-inicial II (0,01% LH), inicial I (0,025% LS), inicial II (0,025% LS); T4- pré-inicial I (0,01% MOS), pré-inicial II (0,005% MOS), inicial I (0,025% LS), inicial II (0,025% LS). Ao final de cada fase de crescimento, os animais foram pesados para o cálculo do consumo alimentar total (CT), ganho de peso (GP) e conversão alimentar (CA). Foram coletadas amostras de sangue, para avaliação dos parâmetros bioquímicos. Ao final do experimento, foram abatidos quatro animais de cada tratamento para a pesagem e mensuração relativa dos órgãos. Não houve diferença estatística quanto ao desempenho zootécnico, peso dos órgãos e parâmetros bioquímicos nos tratamentos propostos pelo experimento (p>0,05). Os resultados demonstraram que a utilização dessas leveduras na alimentação de leitões desmamados, nas dosagens e períodos avaliados, não melhorou o desempenho zootécnico e não alterou os parâmetros bioquímicos.
The aim of this study was to determine whether a pneumoperitoneum of 10 mmHg combined or not with the Trendelenburg position could lead to significant changes in intraocular pressure (IOP), ocular pressure perfusion (OPP), and cardiorespiratory variables; as well as determine whether a correlation exists between IOP and mean arterial blood pressure (MAP), and/or partial pressure of carbon dioxide in arterial blood (PaCO2) in cats. Animals were allocated in two groups (n=7/group): GC (without inclination) and GTREN (Trendelenburg position). The variables were recorded before (baseline) and during 30 minutes (T5-T30) after insufflation. In GTREN, a reduction in heart rate was observed at T5 and in respiratory rate at T5 and T15. There was an increase in IOP at T5-T30 in comparison to baseline. There was a reduction in potential of hydrogen in arterial blood in both groups at all times in comparison to baseline. Partial pressure of carbon dioxide in arterial blood was increased at T15-T30 in GC and at T5-T30 in GTREN. In conclusion, the pneumoperitoneum of 10mmHg CO2 did not significantly affect IOP or OPP in cats anaesthetised with isofluorane and kept under spontaneous ventilation. However, induced pneumoperitoneum combined with Trendelenburg position resulted in an increase in IOP in cats subjected to the same anaesthetic conditions, but did not affect OPP.
