1. Pre-slaughter factors associated with severe bruising in different primary commercial cuts of bovine carcasses
RESUMO A incidência de contusões nas carcaças bovinas é consequência de distintos fatores potencialmente estressantes e agressivos a que são submetidos os animais durante o manejo pré-abate. Este estudo teve como objetivo identificar os fatores pré-abate associados a lesões de contusões severas observadas em diferentes regiões da carcaça dos bovi

3. Histopatology of the reproductive tract of Nellore pubertal heifers with genital ureaplasmosis
ABSTRACT In order to study and characterize the lesions in the reproductive tract of Nellore heifers naturally infected with Ureaplasma diversum and presenting granular vulvovaginitis syndrome (GVS), fragments of uterine tube, uterus, cervix, vagina and vulva of 20 animals were evaluated. The macroscopic lesions of the vulvovaginal mucosa were classified in

4. Feeding habits of mosquitoes (Diptera: Culicidae) in an area of sylvatic transmission of yellow fever in the state of São Paulo, Brazil
AbstractBackground The reintroduction of sylvatic yellow fever in the state of São Paulo after about six decades was confirmed in the Northwestern region in 2000, where in 2008 there also occurred an important epizootic. The purpose of this study was to investigate the feeding habits of culicids potentially involved in the sylvatic transmission of the virus

5. Blood feeding patterns of Nyssomyia intermedia and Nyssomyia neivai (Diptera, Psychodidae) in a cutaneous leishmaniasis endemic area of the Ribeira Valley, State of São Paulo, Brazil
Introduction The aim of this study was to identify the blood feeding sources of Nyssomyia intermedia (Ny. intermedia) and Nyssomyia neivai (Ny. neivai), which are Leishmania vectors and the predominant sandfly species in the Ribeira Valley, State of São Paulo, Brazil, an endemic area for cutaneous leishmaniasis. Methods Specimens were captured monthly be

6. Avaliação do swim-up e do gradiente descontinuo de densidade na pré-seleção do sexo de espermatozoides na produção de embriões bovinos
The purpose of this work was to associate the modified swim-up method with centrifugation in density gradient for the separation of X-bearing spermatozoa. Sperm viability and integrity were evaluated through the Trypan Blue/Giemsa staining method. Quality control of centrifuged spermatozoa was performed in in vitro produced embryos. The results were validate

7. Enfermidades Cutâneas Digitais Bovina: Aspectos Genéticos E Terapêuticos / Digital dermatitis disease bovine: genetic and therapeutic aspects
This study has aimed do evaluate a risk factor for bovine digital dermatitis and the efficacy of 5% aqueous barbatimão extract solution as ancillary in interdigital skin incisional wound repair. One hundred bovine females, 50 Holstein and 50 Girolando, from two different farms were used for the risk factor study. Experimental units were divided into four gr

8. Detecção sorológica e molecular do herpesvírus bovino 1 em estruturas reprodutivas de fêmeas bovinas / Serological and molecular bovine herpesvirus-1 detectation on reproductive structures of bovine females
O objetivo do presente trabalho foi avaliar a condição sorológica de fêmeas bovinas abatidas em um frigorífico quanto à presença de anticorpos contra o Bovine Herpesvirus 1 (Herpesvírus Bovino 1 - BoHV-1). Objetivou-se também avaliar a presença do DNA viral no tecido ovariano, nos ovócitos, líquido folicular e sangue destes animais por meio da Re

9. Detecção do vírus da diarreia viral bovina em carrapatos Rhipicephalus (Boophilus) microplus alimentados em bovino persistentemente infectado= Detection of bovine viral diarrhea virus in Rhipicephalus (Boophilus) microplus ticks fed on persistently infected cattle / Detection of bovine viral diarrhea virus in Rhipicephalus (Boophilus) microplus ticks fed on persistently infected cattle
Background: Bovine viral diarrhea virus (BVDV) is one of the main agents that cause economical losses in cattle worldwide. Congenitally infected calves that are born persistently infected (PI) to BVDV are the main sources of infection to susceptible cattle. Direct contact is the most important form of transmission, but indirect contact can also spread BVDV,

11. Characterization of mitochondrial genotypes in the foundation herd of the Canchim beef cattle breed
The Canchim (5/8 Charolais + 3/8 Zebu) beef cattle breed was developed at Southeast-Embrapa Cattle to take advantage of hybrid vigor and to combine the higher growth rate and beef quality of Charolais with tropical adaptations of Zebu. The development of three lineages (old, new, and crossbred) has increased its genetic basis. The genotypic origin (Bos tauru

12. Pronounced segregation of donor mitochondria introduced by bovine Ooplasmic tranfer to the female germ-line.
Ooplasmic transfer (01) has been used in basic mouse research for studying lhe segregation of mtDNA, as well as in human assisted reproduction for improving embryo development in cases of persistent developmental failure. Using cattle as a large-animal model, we demonstrate that lhe moderate amount of mitochondria introduced by OT is transmitted to lhe offsp
