1. THE USE OF ARTIFICIAL INTELLIGENCE FOR THE PREDICTION OF PRODUCTIVITY PARAMETERS IN SWINE CULTURE
ABSTRACT In similar conditions of food handling and genetics, there are large differences in the final productivity of farms, resulting from inherent factors of the production system. This fact predisposes the need of studies on optimizing the rearing conditions of the farms, in order to verify the main limitations for the producers. Therefore, the present s

2. Single nucleotide polymorphisms from cytochrome b gene as a useful protocol in forensic genetics against the illegal hunting of manatees: Trichechus manatus, Trichechus inunguis, Trichechus senegalensis, and Dugong dugon (Eutheria: Sirenia)
The identification of mitochondrial DNA polymorphisms is one of the most efficient methods for species differentiation. Genotyping of molecular markers using PCR/RFLP is a reliable, sensitive and inexpensive method for the detection of species specific mutations. The major causes of decline in Sirenia populations are accidental and intentional catches, colli

3. Estudos de locos de características quantitativas, de expressão gênica e teste de paternidade em suínos / Studies of quantitative trait loci, genic expression and of paternity testing in pigs
The accomplishment of the present study had as objective: 1) to map Quantitative Trait Loci (QTL) on chromosomes 1, 2, 3, 12, 14, 15 and X in a F2 pig population developed by mating two Brazilian Piau breed sires with 18 dams from a commercial line (Landrace × Large White × Pietrain); 2) investigate the level of expression of candidate genes influencing ec

5. Detecção de locos de características quantitativas nos cromossomos 16, 17 e 18 em suínos / Mapping quantitative trait locos on porcine chromosome 16, 17 and 18
O objetivo ao realizar este trabalho foi o mapeamento de QTL nos cromossomo 16,17 e 18 de suínos e a associação destes a característica de desempenho, de carcaça, órgãos internos e vísceras, de cortes de carcaça e de qualidade de carne. Foi construída uma população F2 provenientes do cruzamento de dois varrões da raça naturalizada Brasileira Pi

6. O gene da miogenina: sequenciamento em suínos e análise filogenética / The myogenin gene: sequencing in swine and phylogenetic analysis
Meat production capacity is related to muscle fibers number show in newborn animals. The muscle fibers are formed in the myogenesis that takes place during the embryonic development, an event that is controlled in part by the MyoD gene family. The Myogenin gene is a member of this family and rules the expression of muscle specific genes. It has an important

7. Efeito da genetica e dos sistemas de insensibilização eletrico e gasoso (CO2) no bem-estar e qualidade de carne de hibridos suinos. / Effect of the genetics and the systems of electric and gaseous insensibilização (CO2) in well-being and quality of swine meat hybrid.
Several researchers have been accomplished by the scientific community with the goal of evaluating the swine welfare during the stunning, however, most of these studies doesn t represent the stunning conditions and genetic background of pigs produced and marketed in Brazil. The present study had as main goal, evaluate the influence of genetic background of t

8. Neuraminidase hemadsorption activity, conserved in avian influenza A viruses, does not influence viral replication in ducks.
The N1 and N9 neuraminidase (NA) subtypes of influenza A viruses exhibit significant hemadsorption activity that localizes to a site distinct from that of the enzymatic active site. To determine the conservation of hemadsorption activity among different NAs, we have examined most of the NA subtypes from avian, swine, equine, and human virus isolates. All sub

9. Interaction of Classical Swine Fever Virus with Membrane-Associated Heparan Sulfate: Role for Virus Replication In Vivo and Virulence
Passage of native classical swine fever virus (CSFV) in cultured swine kidney cells (SK6 cells) selects virus variants that attach to the surface of cells by interaction with membrane-associated heparan sulfate (HS). A Ser-to-Arg change in the C terminus of envelope glycoprotein Erns (amino acid 476 in the open reading frame of CSFV) is responsible for selec

10. Determinants of Virulence of Classical Swine Fever Virus Strain Brescia
Two related classical swine fever virus (CSFV) strain Brescia clones were isolated from blood samples from an infected pig. Virus C1.1.1 is a cell-adapted avirulent variant, whereas CoBrB is a virulent variant. Sequence analysis revealed 29 nucleic acid mutations in C1.1.1, resulting in 9 amino acid substitutions compared to the sequence of CoBrB 476R. Using

11. Significant Improvement in Cloning Efficiency of an Inbred Miniature Pig by Histone Deacetylase Inhibitor Treatment after Somatic Cell Nuclear Transfer1
The National Institutes of Health (NIH) miniature pig was developed specifically for xenotransplantation and has been extensively used as a large-animal model in many other biomedical experiments. However, the cloning efficiency of this pig is very low (<0.2%), and this has been an obstacle to the promising application of these inbred swine genetics for biom

12. Molecular evolutionary genetics of the cattle-adapted serovar Salmonella dublin.
An electrophoretic analysis of allelic variation at 24 enzyme loci among 170 isolates of the serovar Salmonella dublin (serotype 1,9,12[Vi]:g,p:-) identified three electrophoretic types (Du 1, Du 3, and Du 4), marking three closely related clones, one of which (Du 1) is globally distributed and was represented by 95% of the randomly selected isolates.
