In horses, the first premolar teeth of the upper arch, or wolf teeth are small and characteristically vestigial, appear positioned immediately mesial to the root of the first molar tooth, do not act functionally in chewing and can also cause pain in animals. There were evaluated 63 animals of Campolina breed and 58 of Thoroughbred in relation to the presence or absence of wolf teeth. The findings showed that 42.86% of the Campolina horses presented wolf teeth, as well as 3.45% of the Thoroughbred. The variable frequency found discloses that the presence of this tooth is a particular and individual feature of animals. It was observed by applying the Fisher's test (p<0.05) that among equine breeds Thoroughbred and Campolina, there was significant difference (p<0.0001). Otherwise for each of the breeds the occurrence of presence of this tooth among the genders was not observed Thoroughbred (p≤0.496) and Campolina (p≤0.083). Source

Nowadays are observed an increase in the finding of certain wild animals in urban areas, due to environmental changes caused by deforestation and economic use of natural areas. It causes disappearance of usual prey and forces these animals, including snakes, to migrate to urban areas, becoming vulnerable to injuries caused by aggressions, car accidents and capture. Mandibular and maxillar fractures are common in many animal species, representing about 3-6% of all bone fractures in dogs and cats. Mandibular trauma usually occurs as a result of fights, car accidents and improper handling and/or restraint, and fractures can be closed or open, clean or contaminated. The jaw is a flat bone with differences from the long bones that should be taken into consideration for successful treatment, being minimal muscle coverage and need to maintain occlusion factors that influence the definition of the best ostheosynthesis method. The methods of stabilization include using intramedullary pins, wires, external skeletal fixation, bone plate, and acrylic resin. Conventional bone plates are efficient but related to some complications, such as the necessity of muscular elevation and high risk of injuries to mandibular structures. This article describes the successful results of the application of plate and screws in the ostheosynthesis of a mandibular fracture in a female Boa constrictor snake with weight of 8.0 kg and length of 1.80 m, at the RIOZOO Foundation (Rio de Janeiro, RJ, Brazil).

The objective of this study was to analyze the effect of ivermectin (3.15%) on gastrointestinal nematodes found in calves through the fecal egg count reduction test (FECRT), and larval culture in 16 animals from a school farm at the Universidade Estadual do Norte do Paraná. The animals were divided into two experimental groups: animals treated with ivermectin 3.15% (G1 group) and control animals (G2 group). Stool samples were collected from the animals twice i.e., on days 0 and 10 for fecal examinations. There was no significant change in the egg count per gram of feces (EPG) in both the groups. Helminths were found to be resistant to ivermectin (3.15%), due to the observed 5.62% FECRT rate. Cooperia was found to be the dominant nematode larvae present (53% on day 10 day and 8% in day 0), while Trichostrongylus was detected in small numbers (0% on day 0 to 1 % on day 10). The drug was found to be effective only in Trichuris, while the same was inefficient against Haemonchus and Cooperia, although Trichostrongylus and Oesophagostomum were found to be 100 % resistant. Therefore, the findings of this study suggest that ivermectin 3.15% should not be used for the control of nematodes in calves, since most of the parasites demonstrated drug resistance. This is the first report on the resistance of Haemonchus, Cooperia, Trichostrongylus, and Oesophagostomum in cattle to ivermectin 3.15% in the state of Paraná. Source

The objective was to evaluate the effect of inclusion levels of sunflower cake as protein source to replace soybean meal in multiple supplements for cattle grazing during dry season on nutritional parameters. Five steers were used, Nellore, non-castrated, with age and average initial weights of 20 months and 354.7 kg, respectively, divided into five paddocks of 0.25 ha each, consisting of Brachiaria brizantha cv. Marandu. The experiment was divided into 5 × 5 Latin square, composed of five experimental periods of 15 days each and five animals. The strategy adopted was the inclusion of sunflower cake in increasing levels of zero, 270, 406, 540 g/kg supplement and mineral supplement composed only by the will provided in the trough (control). Supplements were formulated to be isonitrogenous (25% CP) and provided the amount of 1.5 kg/animal/day of natural material. The forage mass and the availability of dry matter digestible pontecialmente were 3,120 and 2,379 kg DM/ha respectively. Effect was observed (P <0.10) levels of inclusion of sunflower cake compared to the control of supplement DM intake and BP. The FDMI was numerically higher in the supplemented animals (8.05 kg DM/day) over the control animals (7.09 kg DM/day). There was no effect of the supplements on ruminal pH (P> 0.10). There was a significant difference in the concentrations of NH3-N between animals that received only mineral mixture (8.64 mg/dL) and cattle supplemented with 0 (12.61 mg/dL) and 27% (11.79 mg/dL) of adding TG in time 4 hours after supplementation. However, the concentration of NH3-N, between supplemented animalsindependent of the inclusion of TG was not significant (P> 0.10), but was numerically lower for animals supplemented with 40.6 (10.81 mg/dL) and 54% (10.50 mg/dL) inclusion of sunflower cake. We conclude that the inclusion of sunflower cake in the formulation of the supplements did not interfere with nutritional parameters can replace soybean meal in up to 100% without affect consumption of animals, this level of supplementation.
