This study has attempted to identify determinants of cattle price per kilogram live weight using a log-linear regression model. The estimated model explains about 48% of the variation in market prices of cattle. Price per kilogram live weight of cattle increases with animal characteristics such as age, live weight and grade. Type of sellers, buyers' purposes, festivals, time of transaction and a time trend are also important variables in affecting cattle prices. Farmers tend to sell their animals at price discounts as compared to trader sellers. Cattle sellers suffer from price discounts in selling to buyers with business purposes in comparison to selling to ultimate consumers. Sellers tend to benefit from animal sales during festivals, as they tend to... |

In this study, we compared the levels of neutralizing antibodies induced by inactivated rabies vaccine in cattle by using three alternative immunization procedures. Forty-five bovines (breed nelore) were then organized in three groups (A, B and C, with 15 animals/group). Group A received only one vaccine dose at day zero and Group B received the first dose at day zero and then another dose at day 30 (early booster). Group C was also immunized with two doses; however, the booster was postponed until day 180 after the first dose (delayed booster). Blood samples were withdrawn at days zero (before the first dose) and 30, 210, 390, and 540 after the beginning of immunization and the antibody titers were evaluated by mouse neutralization test. The protocol used... |

The objective of this study was to compare the accuracy between two applanation tonometers, Tono-Pen XL® and Perkins®, in horses and cattle. The eyes of 20 horses and 20 cattle conscious and healthy were evaluated for the in vivo study and both eyes of 5 horses and 5 cattle were used as controls for the postmortem study. In conscious animals, the tonometry was performed with auriculopalpebral nerve block and then topical anesthesia for both tonometers and 1% fluorescein eye drops only for the Perkins tonometer. Readings of intraocular pressure (IOP) in the postmortem study were taken using manometry and tonometry by Tono-Pen XL® and Perkins®. The correlation coefficient (r²) between manometry and applanation tonometers Tono-Pen XL® and Perkins®, in horses,... |

A neosporose em bovinos é uma doença causada pelo protozoário Neospora caninum, identificado pela primeira vez em 1988, em cães com encefalomielite, o hospedeiro definitivo. Estudos sorológicos de vários países demonstraram o parasita como a maior causa de abortos em rebanhos leiteiros. A doença está amplamente disseminada nos diferentes continentes. A importância econômica da neosporose bovina é atribuida principalmente aos custos associados ao aborto, ao valor dos fetos, à inseminação artificial ou à cobertura, à diminuição da produção de leite, ao aumento do descarte e à reposição dos animais.Em bovinos, os dois mecanismos de infecção por N. caninum são as transferência do parasita da mãe para o feto (transmissão vertical ou infecção congênita) e a... |
