1. 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

2. CANA-DE-AÇÚCAR, ALTERNATIVA SUTENTÁVEL E ECONÔMICA NA ALIMENTAÇÃO DE BOVINOS CONFINADOS
Estudou-se no presente trabalho a utilização de cana-de-açúcar como alternativa sustentável e econômica para alimentarem-se bovinos confinados. Fez-se um levantamento da evolução da criação intensiva de bovinos para produção de carne no período de 1.990 a 2006, estudando-se suas características físicas, distribuição geográfica e a utilizaç

3. Performance of Nellore cattle fed individualy or in group, nutrient requirements and proteic evaluation of feeds for ruminants / Desempenho de bovinos Nelore alimentados individualmente ou em grupo, exigências nutricionais e avaliação protéica de alimentos para ruminantes
The present work was developed based on four experiments. The two firsts were conducted aiming to evaluate the fecal dry matter production using total fecal collection or estimated by chromic oxide (Cr2O3), titanium dioxide (TiO2), isolated, purified and enriched lignin of Eucalyptus grandis (LIPE), indigestible neutral and acid detergent fiber (NDFi and ADF

4. Effect of urea on bovine serum albumin in aqueous and reverse micelle environments investigated by small angle X-ray scattering, fluorescence and circular dichroism
The influence that urea has on the conformation of water-soluble globular protein, bovine serum albumin (BSA), exposed directly to the aqueous solution as compared to the condition where the macromolecule is confined in the Aerosol-OT (AOT - sodium bis-2-ethylhexyl sulfosuccinate)/n-hexane/water reverse micelle (RM) is addressed. Small angle X-ray scattering

5. Qualidade da carne de bovinos Nelore (Bos taurus indicus) suplementados com vitamina E / Meat quality of Nellore bovine (Bos taurus indicus) supplemented with vitamin E
In general, the modern consumer uses to evaluate the meat quality through its attributes, such as, muscle color, thickness, tenderness and juiciness, among others. Withstanding the efforts done by Animal Science researchers for the last decades, meat quality can be lost during refrigerate or even frozen conservation due to the occurrence of fatty insaturated

6. Localized immunity in experimental bovine mastitis caused by Mycoplasma dispar.
Development of immunity to reinfection with Mycoplasma dispar occurred in the bovine mammary gland and appeared to be confined to the quarter or quarters previously infected with this mycoplasma; it was not generalized throughout the gland. Immunity followed the inoculation of virulent strains of M. dispar but not of an avirulent strain. The immunity engende

7. Identification of a prion protein epitope modulating transmission of bovine spongiform encephalopathy prions to transgenic mice
There is considerable concern that bovine prions from cattle with bovine spongiform encephalopathy (BSE) may have been passed to humans (Hu), resulting in a new form of Creutzfeldt–Jakob disease (CJD). We report here the transmission of bovine (Bo) prions to transgenic (Tg) mice expressing BoPrP; one Tg line exhibited incubation times of ≈200 days. Like

8. Differentiation-specific alternative splicing of bovine papillomavirus late mRNAs.
Activation of the late promoter (PL) of bovine papillomavirus type 1 (BPV-1) is dependent on the differentiation state of keratinocytes and occurs in the upper layers of the bovine fibropapilloma. In this study, we show by in situ hybridization that a differentiation-specific pattern of BPV-1 late RNA splicing is also seen in the fibropapilloma. RNAs contain

9. The effect of assembly and transit stressors on plasma fibrinogen concentration of beef calves.
Plasma fibrinogen concentration was measured in beef calves at various points within the system presently used to assemble, market and transport calves from one production point to another in order to determine the effect of the stresses encountered. A short haul of 160 km immediately after weaning did not significantly elevate fibrinogen concentration above

10. Distinct Response Kinetics of Gamma Interferon and Interleukin-4 in Bovine Tuberculosis
This study shows that gamma interferon (IFN-γ) and interleukin-4 (IL-4) cytokine responses are produced by peripheral blood cells in cattle infected with Mycobacterium bovis. The different kinetics of the IFN-γ and IL-4 responses to bovine tuberculin and to ESAT-6 following experimental intratracheal infection with M. bovis are described. An early increase

11. Immunity in Experimental T-Mycoplasma Mastitis
Immunity to reinfection with the homologous T-mycoplasma strain has been demonstrated in the bovine mammary gland. This immunity was generalized throughout the udder and was not confined to previously infected quarters. Two out of three cows which were immune to reinfection with the homologous strain were not immune to reinfection with a serologically distin

12. Respiratory Syncytial Virus (RSV) Fusion Protein Subunit F2, Not Attachment Protein G, Determines the Specificity of RSV Infection
Human respiratory syncytial virus (HRSV) and bovine RSV (BRSV) infect human beings and cattle in a species-specific manner. We have here analyzed the contribution of RSV envelope proteins to species-specific entry into cells. In contrast to permanent cell lines, primary cells of human or bovine origin, including differentiated respiratory epithelia, peripher
