| The effect of glycerin inclusion on the intake behavior of heifers was analyzed. During the 102-day experimental period, thirty-six 13-month old heifers, average initial weight 226±12 kg, were distributed in a completely randomized design with four treatments and nine replications: G0.0 = control, G2.8 = 2.8%, G6.1 = 6.1%, and G9.1 = 9.1% glycerin in DM intake. Intake behavior was undertaken by monitoring animal activities for 24 hours every five minutes. The inclusion of glycerin in the diet resulted in a linear decrease in grazing time, linear increase in idle time and quadratic effect on trough time. Moreover, glycerin inclusion did not affect the number of grazing and rumination periods. The number of idle periods showed a quadratic effect, whereas... |

Effect of genus and growth stage on the chemical and mineral composition of tropical grasses used to feed dairy cows. Cien. Inv. Agr. 43(3): 476-485. In tropical production systems, dairy cows are rarely supplemented with minerals, which often lead to mineral imbalances. Grasses grown together in the same soil type and sampled at the same growth stage can vary widely in chemical and mineral composition; therefore, the objective of this study was to characterize the chemical and mineral composition of Urochloa spp., Megathyrsus spp., and Andropogon spp. at three different stages of growth in the same soil type.

| We report exogenous pigmentation in sheep grazing in native pastures in northeastern Brazil. The sheep carcasses from a farm were condemned at the slaughterhouse due to pigmentation of the carcasses and viscera. In visits to the farm, bluish-purple pigmentation of the mucosa was observed in the sheep. In two necropsied sheep, a bluish-purple pigment was observed in the skin, subcutaneous tissue, fat, muscles, cartilage, bones, serous membranes of the forestomachs, kidneys, adrenal glands, and the mucosa of the uterus, urinary bladder, urethra, vagina, trachea, bronchi, and bronchioles. Some bone surfaces, the intima of large arteries, tendons, muscle insertions, and ligaments had a yellow-brown or light brown pigment. However, the pigment was not observed... |

| ABSTRACT: Swainsonine-containing plants comprise a group of important poisonous plants in Brazil. This research aimed to characterize both the behavioral changes related to reproduction and appearance of lesions in the reproductive system of bucks poisoned by Ipomoea brasiliana. I. brasiliana plants were collected and administered at a dose of 4g/kg (800µg swainsonine/kg) to two groups of bucks for 45 days. Goats from Group I were euthanized on the 46th day of the experiment, and goats from Group II were euthanized on the 120th day. Group III was composed of goats that did not receive I. brasiliana and were euthanized on the 120th day of the experiment. Reproductive behavioral changes were observed starting on day 20 and were characterized by an absence... |

| ABSTRACT: The aim of this study was to evaluate the bispectral index (BIS) effects in calves through continuous infusion of propofol with or without fentanyl. Eight Holstein male calves (ages from six to twelve months old) with an average weight of 123±18kg were used. All animals participated in both groups, always keeping a minimum interval of one week between the anesthetic procedures; the calves were randomly distributed between groups. Anesthesia was induced with an intravenous (IV) dose of propofol of 5mg kg-1 in control group (GP) or with propofol (4mg kg-1) associated with IV fentanyl 0.001mg kg-1(GF). All the calves were positioned in right lateral recumbency and were allowed to spontaneously breathe room air. Subsequently, the anesthesia was... |

| ABSTRACT: Megaesophagus is a rare disease in ruminants characterized by regurgitation of rumen contents. In this paper it was described cases of megaesophagus in two sheep and two goats on a farm in the state of Paraíba, Northeastern Brazil. All animals showed regurgitation of rumen contents and weight loss, with a clinical course of several months. At necropsy all animals presented megaesophagus. Histological examination showed segmental muscle necrosis in the esophagus and skeletal muscles. Serum samples from one sheep and one goat were negative for the presence of blue tongue antibodies by ELISA, and whole blood and muscle samples from one goat were negative for this virus by RT PCR. Epidemiological data and pathology suggested that the disease could... |

| The aim of this study was to evaluate ruminal in situ degradability and in vitro digestibility of dry matter (DM) in concentrate supplements containing diverse potato flour pelletized with urea (0%, 4%, 8%, and 12% DM). Samples of feeds were incubated for 0, 2, 4, 8, 12, 24, 36, and 48h in the rumen of four fistulated sheep. Level of urea added had no significant effect (P>;0.05) on the soluble fraction (a) or potentially degradable fraction (b) of the pellets and ranged from 2.1% to 12.2% and 72.9% to 87.5%, respectively. Quadratic effects (P=0.03) of the rate of degradation of fraction "b" ranged from 4.75% h-1to 7.39% h-1; the estimated maximum value at 7.4% h-1was obtained when 5.9% urea was added to the pellet. Quadratic effects (P≤0.02) of the... |

| ABSTRACT: This report aimed to describe a case of peripheral neuropathy in a copper-deficient goat, and highlights the clinical, and pathological features of the disease. The goat had low body score, hyporexia, alopecia, achromotrichia, left hindlimb protraction, paralysis with dragging of digit and difficulty to stand up and microcytic normochromic anemia. Copper concentration in serum was markedly lower (2.0µmol L-1) whereas the iron serum content was significantly increased (51.0µmol L-1). The main gross alteration was the reduction of the quadriceps vastus laterallis muscle volume. Histologically, there was atrophy of the quadriceps vastus laterallis muscle and presence of satellite cells, infiltration of lymphocytes, macrophages and replacement of the... |
