• Abstract

  The pregnancy toxemia (PT) is a disease associated with the energy deficit that affects sheep and goats at the end of gestation, usually with multiple or large fetuses. The objectives of this study are: to study the biochemical profile, blood gas, metabolic and oxidative stress of sheep during pregnancy and in the immediate peripartum (until 48 hours postpartum) and correlate them with th…

  The sheep industry is a growing activity in Brazilian livestock plan is developed in different ways (extensive, semi-intensive, intensive). In creations, has been observed incidence of urolithiasis. Due to this fact, the study of aspects related to the genesis, prevention, diagnosis and treatment becomes necessary and current. Built to the onset of urolithiasis, food is one of the most im…

• Abstract

  Acid-base balance modifications that can affect farm animals, although not usually mean serious problems for health animals, can potentially huge economic losses, especially for cases of acidosis and alkalosis. This study aims to determine and relate the variables haemogasometric: arterial oxygen pressure (PO2), arterial carbon dioxide pressure (PCO2), Pressure Hydrogen (pH), oxygen satur…

• Abstract

  The success of neonatal adaptation is directly related to the establishment of respiratory function that enables efficient gas exchange. Physiologically, the newborns suddenly goes from uterine hypoxic environment to hyperoxic air breathed after birth. In this way, oxigen free radicals are produced and this may be associated with the development of oxidative stress, a condition that has b…

• Abstract

  The obstructive urolithiasis has a high incidence in sheep. The urinary acidification with ammonium chloride is an effective method for preventing the disease. This study aims to determine if the diet provided to the animals in confinement, rich in concentrate, causes lesions in the urinary system of sheep, and to analyze the difference of the histopathological features of the urinary sys…

• Abstract

  The mortality of calves during the first 48 hours of life represents about 7.1% of the animals born. Among the diseases that affect these animals in perinatal and neonatal periods, the respiratory distress syndrome is the most common, and stands out in animals from premature and dystocic births, as well as in calves originating from in vitro fertilization and cloning . The major cause of…
