| Twelve steers were intraruminally administered a high dose (0.5g/kg BW) of urea to study the damage effect of ammonia poisoning on liver and/or muscles. Blood samples were collected to determine ammonia and activities of gammaGT, AST and CK. Eleven steers were successfully poisoned and treated properly, but one succumbed. Poisoned cattle showed high concentration of ammonia, and higher activities of AST and CK. The higher the ammonia, the greater were the activities of AST (r=0.59) and CK (r=0.61). The correlation between AST and CK was high and significant (r=0.80), but not between AST and gammaGT (r=0.19). The activities of AST and CK were higher after the beginning of the convulsive episodes due to ammonia poisoning. Those results showed that occurred... |

| A seven month old female goat showed neck swelling, apathy, appetite and weight loss, restlessness, increased salivation, cough, and regurgitation episodes which occurred post feeding. The animal was evaluated through both clinical and radiographic examinations. Plain radiography was performed and contrasted X-ray was done using barium sulfate. For radiological examination, the lateral projection was used for analysis. The results showed a radiopaque content in the esophageal lumen dorsally positioned to heart with density and appearance similar to the rumen. A dilation of the esophagus was reported and a diagnosis of megaesophagus was made. In conclusion, contrast esophagography must be included in the diagnosis of megaesophagus in goats. |

| ABSTRACT The aim of this study was to evaluate the effects of different concentrations of (+)-catechin or (-)-epigallocatechin gallate (EGCG) on goat semen freezability. Poolsof semen were processed (Experiment 1: 0, 15, 25, 50, 75, or 100µM (+)-catechin; Experiment 2: 0, 15, 25, 50, 75, or 100µM EGCG) and frozen. After thawing, the samples were evaluated for kinematics, plasma membrane (PMi) and acrosome integrity, morphology, and oxidative stress, at 0 and 1h. In Experiment 1, at 0h, VSL and VAP were greater (P<0.05) with 15µM than with 50 and 100; WOB was lower (P<0.05) with 100µM than with 0, 15, and 25; and BCF was higher (P<0.05) with 75 and 100µM than with 0. In turn, in Experiment 2, progressive motility was higher (P<0.05) with0 and... |

| In order to study the effects of different local anaesthetics with and without vasoconstritor (epinefrine), 20 adult crossbred cows were used. The following treatments were carried out:T1 - control (bidistilled water); T2 - chloridrate of lidocaine (20 mg/ml) with epinephrine (0.005 mg/ml); T3 - chloridrate of lidocaine (20 mg/ml) with epinephrine (0.02 mg/ml); T4 - chloridrate of lidocaine (20 mg/ml) with epinephrine (0.05 mg/ml); T5 - chloridrate of lidocaine(20 mg/ml); T6 - chloridrate of procaine (22 mg/ml) with epinefrine (0.02 mg/ml); T7 - chloridrate of procaine (22 mg/ml). The different solutions were injected, at the same time, into the subcutaneous space of the medial chest line, 10cm apart, of all cows. Observation at the infiltration sites was... |

| Ten young rumen-cannulated crossbred steers were randomly divided into two groups: a control group (C; n=4), which was fed a balanced diet for daily weight gain of 900g; and a pronounced energy-deprived group (PED; n=6), receiving 30% less of the required energy for maintenance. After 140 days of these alimentary regimes, rumen fluid and urine samples were collected for biochemical and functional tests, before feeding and at 1, 3, 6, and 9 hours after feeding. The energy-deprivation diet caused a significant reduction in the number of Entodinium, Eodinium, Isotricha, Dasytricha, Eremoplastron, Eudiplodinium, Metadinium, Charonina, Ostracodinium, and Epidinium protozoa. There was no effect of the time of sampling in both groups on the total number of... |

| ABSTRACT The objective of this study was to evaluate the metabolic response of native lambs fed Tifton 85 hay (Cynodon dactylon) or Maniçoba hay (Manihot pseudoglaziovii) associated with spineless cactus (Nopalea cochenillifera Salm Dyck). Sixteen Morada Nova lambs were used, with a mean initial weight of 19.36±1.48kg, distributed in a randomized block design, with two treatments and eight replications. Dry matter intake was higher for lambs fed Maniçoba hay compared to Tifton hay, while the body weight at slaughter was not influenced by diets. Regarding the blood metabolites, only the serum concentration of urea was influenced, with higher value observed in the lambs that fed the diet containing Tifton hay. When analyzing blood biomarkers, in the... |

| Aiming to evaluate the effect of the diet protein content on testicular parameters in pigs, 21 non-gelded male Dalland pigs were used and randomly divided into three groups. Males belonging to groups G2 and G3 received a diet with crude protein levels of 15% below and above, respectively, in relation to G1 (control). At 210 days of age, animals were castrated, and testis and epididymis were collected for morphometric and histomorphometry analyses. No difference was observed in relation to the total length of seminiferous tubules (G1=3239.9±333,3m; G2=2989.4±171,7m and G3=3059.5±254.9m), population of Sertoli cell (G1=4.7±0.5x10(9); G2=4.3±0.3x10(9) and G3=4.7±0.5x10(9)), population (G1=31.6±5.58x10(9); G2=27.3±4.0x10(9) and G3=26.4±3.9x10(9)) and volume of... |

| RESUMO O tiametoxam é um inseticida neonicotinóide usado em diversas culturas e classificado como perigoso para o meio ambiente.O objetivo do presente trabalho foi avaliar a toxicidade aguda do inseticida, por meio da determinação da CL50%, e o risco ecotoxicológico com mensuração da concentração ambiental estimada (CAE) e do quociente de risco (QR). O experimento foi realizado com alevinos de tilápias expostas a 150, 300, 450, 600 e 750mg/L de Actara(r) WG por um período total de 96 horas. O oxigênio dissolvido, o pH e a temperatura foram mensurados diariamente em todos os aquários. Nos grupos experimentais, houve uma variação dos valores de pH e de OD para as diferentes concentrações do inseticida. A CL50% 96h do Actara(r) para alevinos de tilápia foi de... |
