Resumo: O estresse acadêmico tem sido uma preocupação atual, uma vez que estudantes universitários são expostos rotineiramente a situações desafiadoras em seu processo de crescimento e desenvolvimento pessoal e profissional. A complexidade dos cursos e a transição e adaptação por um novo momento acadêmico pode levar ao estresse e, consequentemente,...

Este estudo tem como objetivo levantar e discutir os efeitos da presença de cães (Canis lupus familiaris L.) na Unidade de Conservação de proteção integral Reserva Biológica Serra dos Toledos, bioma Mata Atlântica, localizada no Município de Itajubá, Sul de Minas Gerais. Foi realizado o levantamento por meio de observações diretas entre os dias 01...

RESUMO O presente trabalho objetivou comparar o efeito do flunixin meglumine, cetoprofeno e meloxicam no tratamento da dor pós-operatória de ovinos submetidos à implantação de cânula ruminal e orquiectomia. Foram utilizados 32 ovinos, machos, pesando em média 35,5±3,5kg, distribuídos em três grupos: GFlu (flunixin meglumine 1,1mg/kg i.v.), GCet (ce...

The present study aimed to evaluate the efficiency of hypertonic saline solution (HSS) as a novel treatment of acute ruminal lactic acidosis (ARLA) in cattle, focusing on urinary excretion of acids. Twelve cannulated steers were submitted to experimentally induced ARLA by administering sucrose into the rumen. Twenty hours later, the cattle were ran...

Background: Acute ruminal lactic acidosis (ARLA) is a major nutritional and metabolic disorder usually characterized by excessive or non-adapted intake of diets rich in nonstructural carbohydrates. Feed additives that regulate the ruminal environment have been used to prevent ARLA, such as ionophores and, more recently, yeast culture. Thus, we aim...

The aim of this study was to evaluate the effects of two additives (probiotic and monensin) over clinical parameters of sheep submitted to acute ruminal lactic acidosis (ARLA). Eighteen sheeps were divided into three groups of six animals each as follows: probiotic group, supplemented with 4×109 CFU/animal/day of Saccharomyces cerevisiae; monensin...

The Ptychopetalum olacoides Benth. (Olacaceae) is an Amazonian tree popularly known as muirapuama or marapuama, among other names, which is used for several central nervous system related problems. The roots and occasionally the bark roots are the main medicinal parts employed and are prepared as an alcoholic infusion, tinctures, and tea. Phytochem...

No presente trabalho estudaram-se os efeitos de duas quantidades diferentes de melão com alto teor de açúcares, oferecidas subitamente a ovinos não adaptados, sobre algumas variáveis clínicas. Foram utilizados 12 ovinos canulados, mestiços da raça Santa Inês, machos, pesando 25 kg, com oito meses de idade e que nunca haviam recebido rações concentr...

O presente trabalho avaliou os efeitos da administração de duas diferentes quantidades de melão sobre variáveis hemogasométricas, bioquímicas e hematológicas de ovinos não adaptados. Foram utilizados 12 ovinos canulados, pesando 25kg de peso vivo, que nunca receberam ração concentrada. Os animais receberam dieta à base de feno (2,3% do peso vivo) e...

In this study we examined the effects of different feed concentrates on sheep behaviour. Our hypothesis was that citric pulp would stimulate rumination and be capable of replacing other concentrates traditionally used for feeding in confinement, to reduce the risk of urolithiasis. Ten adult Santa Inês sheep were distributed in a Latin square with f...

We aimed to compare the measurements of sheep ruminal pH using a continuous telemetry system or a bench pH meter using sheep with different degrees of ruminal pH. Ruminal lactic acidosis was induced in nine adult crossbred Santa Ines sheep by the administration of 15 g of sucrose per kg/BW. Samples of rumen fluid were collected at the baseline, bef...

Eight adult Santa Inês sheep received a control diet (C) (80% of coast-cross hay and 20% of commercial feed) and then they were submitted to a Latin square experiment with diets containing 30% of hay and 70% of the following concentrates: pelleted citrus pulp (PCP), citrus pulp meal (PCF), cornmeal (FM) or wheat bran (FT). After 21 days of adaptati...

Twelve healthy Santa Inês sheep, non-pregnant and non-lactating underwent a protocol of experimental induction of nervous ketosis for studying the symptoms in ketosis and Pregnancy Toxaemia (PT) disease. Eight animals were subjected to infusion of 150 mL of isopropanol (IPA) at 35% in the jugular vein and four sheep were treated identically with is...

Doze ovelhas hígidas, não prenhes e não lactentes foram submetidas a um protocolo de indução experimental de cetose nervosa para a avaliação de sintomatologia nos quadros de cetose e Toxemia da Prenhez. Neste protocolo, oito animais foram submetidos a infusão de 150 mL de solução de isopropanol a 35% na veia jugular, constituindo o grupo Tratado (G...

Hypertonic saline solution (HSS) is known as an important treatment for hypovolemic shock. Cattle with acute rumen lactic acidosis (ARLA) usually present different degrees of dehydration. This study evaluated the efficiency of HSS for treatment of ARLA. Twelve yearling, cross-bred, male cattle were used. After an adaptation period, when a rumen can...

Four 1.5-year-old, male, Murrah buffalos were maintained during eight months without direct solar exposure during a study of copper toxicosis. Four days after solar exposure, all buffalos presented clinical manifestations consistent with acute photosensitization, including anorexia, apathy, loss of body weight, and generalized cutaneous lesions. Gr...

Liver biopsy in ruminants is an important technique for clinical diagnosis of toxic and metabolic diseases, especially mineral disorders. The most frequent procedures used so far results in an small amount of liver and not enough for multiple tests. The present study aims to evaluate the efficacy of paracostal laparotomy liver biopsy technique in c...
