1. Effect of low or high stress in pre-slaughter handling on pig carcass and meat quality
The objective of this study was to evaluate the consequences of low or high stress during pre-slaughter handling of pigs on their carcass and meat quality. Forty-four animals of a commercial lineage, with an average weight of 107.23±5.23 kg, were used. At lairage the animals were randomly divided into two groups, the least and the most stressed. At slaughte

2. Suíno como modelo experimental na pesquisa biomédica: valores fisiológicos normais = Swine in biomedical research: normal physiological values / Swine in biomedical research: normal physiological values
Background: The use of animals in biomedical research is of great importance. It is fundamental for the development and improvement of new practices and technologies. The selection of the species must take into consideration the practicality of handling and the suitability for the experiment, and it must have low operational costs. Swine are important as an

4. Detecção de reatividade divergente pelo teste de labirinto e sua implicação em indicadores fisiológicos e musculares de estresse em suínos sob diferentes manejos pré-abate / Detection of reactivity divergent by maze test and its implication in physiological indicators and muscle of stress in pigs under different handling pre-slaughter
Numerous studies have demonstrated the relationship between behavioral and physiological measures of stress in pigs at slaughter and subsequent effects on meat quality. One way to study this relationship is through behavioral tests. The test Y maze is used especially to determine the relationship of aversion front the different procedures for handling. The o

5. Salmonella sp em rebanho comercial de suínos e em suas carcaças processadas no frigorífico / Salmonella sp FLOCK IN TRADE OF PIGS AND CARCASSES PROCESSED IN SLAUGHTERHOUSE
The slaughter of pigs with Salmonella sp is considered the first critical point for contamination of the final product. The risk represented by these animals tends to increase when this bacterium is present in portions of the carcass that reaches the consumer. In this study, we sought to verify the association of the prevalence of pigs with Salmonella sp in

6. Norms of animal production in intensive rearing : scenario for national legislation on animal welfare / Normas de produção de animais submetidos a sistema intensivo : cenario da legislação nacional sobre bem-estar animal
Brazil is the producing greater of meat of the world and has an important exterior market. Face to the new international demands of animal well-being, there is the need to update the Brazilian legislation, that dates of years 30? and it does not reflect the actual animal Brazilian production. Regarding the conditions of the Brazilian agribusiness growth and

7. Contact with pigs and cats associated with high prevalence of Toxoplasma antibodies among farmers.
Antibodies to Toxoplasma were measured by enzyme linked immunosorbent assay (ELISA) in sera from 159 abattoir workers, 142 pig farmers, and 106 grain or berry farmers. Farmers occupationally exposed to pigs had antibodies in 53 (37%) cases, abattoir workers in 40 (25%) cases, and farmers not exposed to pigs in 24 (23%) cases. In each group antibodies were mo

8. Effect of neonatal modulation of cholesterol homeostasis on subsequent response to cholesterol challenge in adult guinea pig.
Experiments were designed to study whether or not the mechanism of handling dietary cholesterol in adulthood can be modulated by the manipulation of cholesterol homeostasis during neonatal period. The effects of enhancing cholesterol degradation (cholestyramine feeding), high dietary cholesterol intake, and early weaning during neonatal period of guinea pigs

9. Analysis of polypeptide composition and antigenic components of Rickettsia tsutsugamushi by polyacrylamide gel electrophoresis and immunoblotting.
Polyacrylamide gel electrophoresis of lysates of purified Rickettsia tsutsugamushi revealed as many as 30 polypeptide bands, including major bands corresponding to molecular sizes of 70, 60, 54 to 56, and 46 to 47 kilodaltons. Compared with the polypeptide composition of the rickettsiae of Gilliam, Karp, and Kato strains and a newly isolated Shimokoshi strai

10. Different types of ganglion cell in the cardiac plexus of guinea-pigs.
1. Intracellular recordings were made from the parasympathetic ganglion cells that lie in the epicardium of the left atrium of guinea-pig heart near the interatrial septum. 2. Three distinct types of neurone were identified on the basis of their electrophysiological properties. In one group of neurones, S cells, somatic action potentials were followed by bri
