Twelve yearling Girolando, rumen-fistulated steers never fed with urea before, were distributed randomly in 2 groups of 6 animals each. Both groups were administered intraruminally a single dose (0.5 g/kg BW) of extruded (G1) or prilled (G2) urea to induce ammonia poisoning. The clinical picture was followed for the next 240 min. Besides the classic signs the present study found 3 new additional sign: dehydration, hypothermia and ingurgitated episcleral veins. Convulsion, considered the definite sign, was seen in 5 out of 6 animals from both groups. One steer (G1) had only fasciculation, while another (G2) developed typical clinical signs, but not convulsion, and recovered spontaneously without treatment. The appearance of clinical signs such as muscle... |

The purpose of the present study was to establish a practical, fast, precise and low-cost procedure to estimate the degree of metabolic acidosis in cattle with acute rumen lactic acidosis for further treatment. The rumen acidosis was induced experimentally in 40 crossbreed rumen-cannulated 1.5-year-old steers. The induction caused the development of the most characteristic clinical signs of acute rumen lactic acidosis, severe rumen acidosis and a moderate metabolic acidosis, which was evidenced by low blood pH, and blood bicarbonate concentration and base excess (BE). A highly positive correlation (r=0.80) between urinary pH and BE concentration, and between urinary pH and blood pH (r=0.75) was observed. The BE concentration estimated by urinary pH was... |

Para testar a eficiência de vários tratamentos de intoxicação por amônia em bovinos, foram utilizados 25 garrotes que receberam cloreto de amônio por infusão intravenosa (iv) até o surgimento de quadro convulsivo. Em seguida, os animais foram alocados em um dos cinco grupos experimentais e tratados da seguinte forma: 1) controle: infusão (iv) de 300mL de solução salina isotônica (SSI), no decorrer de 4h; 2) infusão (iv) de 30mL kg-1 PV de SSI no decorrer de 4h e administração de 4L de água intraruminal por meio de sonda esofágica (ASE); 3) mesmo tratamento do grupo 2 e dose única (iv) de furosemida (2mg kg-1 PV) (F); 4) injeção (iv) de 5mL kg-1 PV de solução salina hipertônica (SSH) 7,2% nos primeiros 30min, seguida de 20mL kg-1 PV de SSI e 4L de ASE; 5)... |
