1. Farm animals against open borders: uncovering discrepancies between narratives and evidence regarding actors and motives in the animal trade
RESUMO: O artigo examina os discursos dominantes no debate sobre o transporte e comércio de animais vivos antes de analisar os dados do comércio da base de dados da ONU Comtrade. Entre 1998 e 2015, o comércio de bovinos aumentou ligeiramente, o comércio de suínos aumentou 76%, enquanto o comércio de aves mais do que duplicou. Demonstra-se que há uma

2. New approaches, development, and improvement of methodologies for the assessment of B-vitamin requirements in dairy cows
ABSTRACT Studies on B-vitamin requirements of cattle, conducted more than 60 years ago, concluded that mature ruminants do not require B-vitamin supplements because the amounts of vitamins provided by the diet and synthesized by the ruminal microflora were sufficient to prevent emergence of deficiency symptoms. As a result, the impact of subclinical deficien

3. Live weight and metabolic hormone profile in steers moved in drives
The objective was to determine the effects of driving on the growth of steers during 55 days of moving by drive and 84 days after the arrival. Twenty-five steers were randomly chosen from a herd of 1,000 Nellore cattle, which were evaluated in two periods: the driving period, in which animals were moved a distance of 700 km on foot for 55 d; and the post-dri

4. Uso das terras e legislação ambiental: a microbacia do Ribeirão Sapé no município de Caldas Novas (GO) / Land use and environmental legislation: the micro-basin of the municipality of Ribeirão Sapé in Caldas Novas (GO)
From the 1930s Brazil created many laws to protect the natural resources. But with the implantation of incentive programs which aim the economic growth at any cost, with modern farming practices and the expansion of agriculture and cattle raising, great losses occurred to the preservation and conservation of the natural resources. The driving question for th

5. Significações e ressignificações do patrimônio cultural: as fazendas históricas e o turismo nos Campos Gerais do Paraná / Signification and re-signification of cultural heritage: the historical ranches (fazendas) of the Campos Gerais region in Southern Brazil and tourism
The activity of cattle driving (tropeirsimo) has been a historical marker in the history of Brazil throughout the 18th and 19th century resulting in the effective integration of the South into the whole of the country. Thus, the Campos Gerais region has become an important element in the countrys structure. Cattle driving has left us an important historical-

6. Prion protein gene (PRNP) variants and evidence for strong purifying selection in functionally important regions of bovine exon 3
Amino acid replacements encoded by the prion protein gene (PRNP) have been associated with transmissible and hereditary spongiform encephalopathies in mammalian species. However, an association between bovine spongiform encephalopathy (BSE) and bovine PRNP exon 3 has not been detected. Moreover, little is currently known regarding the mechanisms of evolution

7. Antimicrobial Resistance of Escherichia coli O157 Isolated from Humans, Cattle, Swine, and Food
A total of 361 Escherichia coli O157 isolates, recovered from humans, cattle, swine, and food during the years 1985 to 2000, were examined to better understand the prevalence of antimicrobial resistance among these organisms. Based on broth microdilution results, 220 (61%) of the isolates were susceptible to all 13 antimicrobials tested. Ninety-nine (27%) of

8. Stable Transfection of the Bovine NRAMP1 Gene into Murine RAW264.7 Cells: Effect on Brucella abortus Survival
Genetically based natural resistance to brucellosis in cattle provides for novel strategies to control zoonotic diseases. Bovine NRAMP1, the homologue of a murine gene (Bcg), has been identified as a major candidate for controlling the in vivo resistant phenotype. We developed an in vitro model for expression of resistance- and susceptibility-associated alle

9. Control of gene expression in trypanosomes.
Trypanosomes are protozoan agents of major parasitic diseases such as Chagas' disease in South America and sleeping sickness of humans and nagana disease of cattle in Africa. They are transmitted to mammalian hosts by specific insect vectors. Their life cycle consists of a succession of differentiation and growth phases requiring regulated gene expression to
