Carcass traits of Nellore, F1 Simmental × Nellore and F1 Angus × Nellore steers...
Oliveira,Ivanna Moraes de; Paulino,Pedro Veiga Rodrigues; Valadares Filho,Sebastião de Campos; Detmann,Edenio; Paulino,Mário FonsecaThis trial was conducted to evaluate the quantitative carcass traits of Nellore, F1 Simmental × Nellore and F1 Angus × Nellore steers fed at maintenance level or ad libitum with 1% and 2% of the body weight in concentrate. The animals were allotted to the treatments in a completely randomized experimental design, in a 3 × 3 factorial arrangement. The animals fed the ad libitum diet with more concentrate had gre...
Relationship between the Porcine Stress Syndrome gene and pork quality traits o...
Band,Guilherme de Oliveira; Guimarães,Simone Eliza Facioni; Lopes,Paulo Sávio; Schierholt,Alex Sandro; Silva,Kleibe Moraes; Pires,Aldrin VieiraThe PSS genotypes of 596 F2 pigs produced by initial mating of Brazilian commercial sows and native boars were characterized by PCR-RFLP and the pork quality traits were evaluated. Among the 596 pigs studied, 493 (82.7%) were NN and 103 (17.3%) were Nn. There were no differences between NN and Nn pigs in the following pork qualities: pHu (5.71 ± 0.16 vs 5.70 ± 0.11), intramuscular fat (1.55 ± 0.64% vs 1.65 ± 0....

Band,Guilherme de Oliveira; Guimarães,Simone Eliza Facioni; Lopes,Paulo Sávio; Peixoto,Jane de Oliveira; Faria,Danielle Assis; Pires,Aldrin VieiraThe PSS genotypes of 596 F2 pigs produced by initial mating of Brazilian native boars commercial sows and were characterized by PCR-RFLP and their carcass and performance traits were evaluated. Among the 596 animals analyzed, 493 (82.72%) were characterized as NN and 103 (17.28%) as Nn. With respect to carcass traits, Nn animals presented higher (p < 0.05) right half carcass weight, left half carcass weight, lo...
Association of MYF5 gene allelic variants with production traits in pigs
Carmo,Fausto Moreira da Silva; Guimarães,Simone Eliza Facioni; Lopes,Paulo Sávio; Pires,Aldrin Vieira; Guimarães,Marta Fonseca MartinsWe studied the phenotypic effects of polymorphisms at the MYF5 gene in a divergent F2 swine population and found that one polymorphism was due to an insertion and another to a deletion. The genotypes of 359 F2 animals were obtained and the Normal/Normal (NN) and Normal/Insertion (NI) genotypes analyzed to determine associations with phenotypic data for performance, carcass and meat quality traits. Significant d...
Antibacterial activity of lactic cultures isolated of Italian salami
Maciel,Janeeyre Ferreira; Teixeira,Magdala Alencar; Moraes,Célia Alencar de; Gomide,Lúcio Alberto de MirandaLactic acid bacteria were isolated in the MRS, D-MRS and M17 modified media, during the processing of Italian salami, obtained from two processing plants, in the State of Paraná. The 484 isolates were tested for their antibacterial activity against Listeria monocytogenes (Microbiology Laboratory-UFV), Staphylococcus aureus (ATCC 25923), Salmonella enteritidis (ATCC 13076) and Escherichia coli (ATCC 25922), by a...
