1. Characterization and influence of production factors on growing and finishing pig farms in Brazilian cooperatives
ABSTRACT The objective of this study was to identify and quantify, through mathematical models, the main factors of production in growing and finishing pig units linked to three Brazilian cooperatives located in Western Region of Paraná State that influence the parameters of daily feed intake and feed conversion ratio. The records of 216 growing and finishi

2. Differentially expressed genes and miRNA identification in pig skeletal muscle / Identificação de genes diferencialmente expressos e miRNAs em músculo esquelético de suínos
The pig (Sus scrofa) is considered an important animal for meat production. This interest revolves around the potential for muscle growth, which usually is associated with certain characteristics during prenatal myogenesis. To study the genes responsible for these characteristics, expressed sequence tags (EST) provide direct information about the transcripto

3. Número de marcadores SNP para estimação de consangüinidade, parentesco e identificação de paternidade em suínos / Number of SNP markers for parental identification, kinship and inbreeding estimation in pigs
Um dos pontos-chave do BLUP (melhor predição linear não viesada), utilizando as equações de modelos mistos, é apontado como o uso da matriz de parentesco (A) para estimação dos valores genéticos. No entanto, a matriz A pode ser responsável também pela perda de acurácia devido: 1) aos erros de pedigree e 2) aos coeficientes de endogamia e de paren

4. 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. ReduÃÃo de nutrientes em raÃÃo com fitase para suÃnos em crescimento / Reduction of nutrients in diets with phytase for growing pigs
Two experiments were conducted in the Animal Science Department at the Federal University of Lavras to evaluate different formulations of diets containing levels of nutrients and energy reduced in accordance to a nutritional plan of phytase, in order to establish the contribution of the enzyme through performance, energy and nitrogen balance, availability of

6. Níveis de expressão dos genes FABP3 e FABP4 e conteúdo de gordura intramuscular em suínos / Expression levels of the FABP3 and FABP4 genes and intramuscular fat content in pigs
Genes FABP3 (heart fatty acid-binding protein gene) and FABP4 (adipocyte fatty acid-binding protein gene) have been indicated as candidate genes to the intramuscular fat deposition in pigs. The present research aimed to analyze the levels of expression of these genes in the Longissimus dorsi (LD) and Semimembranosus (SM) muscles of commercial (Landrace X Lar

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. Evolution of ascariasis in humans and pigs: a multi-disciplinary approach
The nematode parasite Ascaris lumbricoides infects the digestive tracts of over 1.4 billion people worldwide, and its sister species, Ascaris suum, has infected a countless number of domesticated and feral pigs. It is generally thought that the putative ancestor to these worms infected either humans or pigs, but with the advent of domestication, they had amp

9. Development of a quantitative competitive reverse transcriptase polymerase chain reaction for the quantification of growth hormone gene expression in pigs
After the advent of the genome projects, followed by the discovery of DNA polymorphisms, basic understanding of gene expression is the next focus to explain the association between polymorphisms and the level of gene expression, as well as to demonstrate the interaction among genes. Among the various techniques for the investigation of transcriptional profil

10. Effects of diet and genetics on Mycobacterium bovis BCG vaccine efficacy in inbred guinea pigs.
Strain 2 and strain 13 guinea pigs were vaccinated with Mycobacterium bovis BCG and placed on low-protein or protein-adequate diets. Five weeks later all animals were infected by the respiratory route with virulent Mycobacterium tuberculosis H37Rv organisms. Four weeks postchallenge, guinea pigs were skin tested with purified protein derivative and sacrifice

11. 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

12. 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
