Crude glycerin inclusion in Santa Inês ewes' diet before and during the breeding season: its effects on physiological parameters, hematological variables, and reproductive performance / Inclusão de glicerina bruta na dieta de ovelhas Santa Inês antes e durante a estação de monta: Seus efeitos nos parâmetros fisiológicos, variáveis hematológicas e desempenho reprodutivo

In this study, we aimed to evaluate the effect of concentrate supplementation containing crude glycerin (CG) before and during the breeding season on the physiological and blood biochemical variables as well as on the reproductive performance of Santa Inês ewes. A total of 24 ewes (12 pluriparous and 12 nulliparous ewes, 4 and 1.5 years old, weighing an average of 40 ± 5 and 27 ± 3 kg, respectively) were randomly assigned to three treatments consisting of different dietary concentrations of CG (0%, 5%, and 10 % of the total dry matter). The experiment lasted 63 days and was divided into three 21-day phases. In the first and second phases, the animals were subjected to flushing. In the second and third phases, we evaluated the animals' reproductive performance. Weather, physiological, and blood biochemical variables were also studied. The results indicated that the inclusion of CG did not influence significantly (P > 0.05) either the ewes' body weight or their body condition score. All ewes exhibited estrus during the breeding season. Their respiratory rate was significantly influenced by the time of day (P < 0.0001). A 10% CG supplementation did not drastically change the hematological and biochemical variables, which were within the reference ranges. However, the week of supplementation influenced sérum metabolites (P < 0.05). Thus, these results indicate that CG could be used in up to 10% in replacement of ground corn without significantly affecting the physiological, hematological, and biochemical parameters of the ewes or their reproductive performance before and during the breeding season.(AU)

Neste estudo, objetivamos avaliar o efeito da suplementação concentrada contendo glicerina bruta (GB) antes e durante a estação de monta sobre as variáveis bioquímicas e fisiológicas, bem como sobre o desempenho reprodutivo das ovelhas Santa Inês. Um total de 24 ovelhas (12 pluríparas e 12 nulíparas, de 4 e 1,5 anos de idade, pesando em média 40 ± 5 e 27 ± 3 kg, respectivamente) foram distribuídas aleatoriamente em três tratamentos constituídos por diferentes concentrações dietéticas de GB (0, 5 e 10% da matéria seca total). O experimento durou 63 dias e foi dividido em três fases de 21 dias. Na primeira e segunda fase, os animais foram submetidos ao flushing alimentar. Na segunda e terceira fase, avaliamos o desempenho reprodutivo dos animais. Variáveis climáticas, fisiológicas e bioquímicas sanguíneas também foram estudadas. Os resultados indicaram que a inclusão de GB não influenciou significativamente (P > 0,05) no peso corporal das ovelhas nem em seu escore de condição corporal. Todas as ovelhas exibiram estro durante a estação reprodutiva. A frequência respiratória foi significativamente influenciada pela hora do dia (P < 0,0001). Uma suplementação com 10% de GB não alterou drasticamente as variáveis hematológicas e bioquímicas, que estavam dentro do intervalo de referência. No entanto, a semana de suplementação influenciou os metabólitos séricos (P < 0,05). Sendo assim, esses resultados indicam que a GB pode ser utilizada em até 10% na substituição do milho moído, sem afetar significativamente os parâmetros fisiológicos, hematológicos e bioquímicos das ovelhas assim como o desempenho reprodutivo antes e durante a estação de monta.(AU)

Anestesia em paciente oncológico submetido à mastectomia - relato de caso / Anesthesia in cancer patient undergoing to mastectomy - case report

The choice of the ideal anesthetic protocol must consider a number of factors, providing minimum anesthetic time, little cardiopulmonary depression and management of anesthesia must keep vital signs and physiological parameters monitored. Patients with neoplasia are even more important, because, normally, middle-aged or elderly animals show changes who qualified him as patients with risk category III or IV. The present study reports the case of a female dog SRD 10-year-old carrier of breast cancer submitted to unilateral mastectomy, highlighting the importance of the anesthetic protocol used.

Uso de resíduo lipídico sobre os parâmetros bioquímicos de ovelhas deslanadas durante a estação de monta / Use of lipid residue on biochemical parameters of woolless sheep during the breeding season

The objective was evaluate inclusion of increasing levels of lipid residue in diet, replacing energysources commonly used in blood biochemical parameters of woolless sheep during the breeding season. Wasused 24 sheep, between 1 and 6 years old, with an average of 40 kg. The experiment lasted nine weeks. In firstsix weeks the sheep received flushing, where diets were formulated with increasing levels of lipid residue includereplacing corn and soybean meal, and (T1) without addition of waste, (T2) with 5% (T3 ) 10%. The blood serumchemistries for performing was collected once weekly throughout the trial period. The results of the biochemicalanalyzes of cholesterol, triglycerides and glucose showed no statistical difference. The increasing levels of lipidresidue in the diet did not change the blood biochemical parameters of woolless sheep during the breedingseason.(AU)
