Resumo: | The objective of this study was to verify the performance and carcass quality of pigs from four genetic lines and to correlate these data with the number and diameter of muscle fibers. A total of48 pigs were used and distributed into four treatments: high-lean commercial crossbred line; prolificacy commercial crossbred line; (Landrace X Large White) crossbred animals; and undefined genetic line. The experimental design consisted of a complete randomized design with a 4 x 2 factorial arrangement (4 genetic lines and 2 genders). Daily weight gain, daily feed intake and the feed conversion were evaluated. At slaughtering, the carcasses were evaluated and the number and the diameter of the muscle fibers of longissimus dorsi were assessed. The high-lean commercial line presented the greatest number of muscle cells (P<0.05) while the Landrace x Large White crossbred line presented the greater diameter (P<0.05). High-lean commercial line showed a better performance and carcass characteristics compared with the undefined genetic line (P<0.05) and the barrows presented the lowest results (P<0.05). The increment in the muscle fiber number affected positively the performance and carcass characteristics of pigs.KEYWORDS: diameter of the muscle fibers; genetic groups; lean deposition; gender. |

Foram utilizados 48suínos, distribuídos em um delineamento completamente casualizados em esquema fatorial 4 x 2 (4 linhagens e 2 gêneros). As linhagens genéticas avaliadas foram: linhagem comercial para carne; linhagem comercial paraprolificidade; cruzados Landrace x Large White; e sem genética definida. Foram avaliados o ganho de peso, o consumo de ração, a conversão alimentar, as carcaças e o número e diâmetro das fibras musculares do longissimusdorsi. As linhagens selecionadas para deposição de carne apresentaram maior número de fibras e o grupo sem genética definida o menor (P<0,05). Os animais Landrace x Large White apresentaram maior diâmetro celular(P<0,05). Linhagens selecionadas para deposição de carne apresentaram melhor desempenho e qualidade de carcaça que os animais sem genética definida (P<0,05). Os machos castrados apresentaram menor número de fibras,pior conversão alimentar e características de carcaça. Através da análise de correlação, conclui-se que o aumento no número de fibras musculares foi positivo sobre as características de crescimento e de carcaça dossuínos.PALAVRAS-CHAVE: deposição de carne; diâmetro celular; gênero; grupos genéticos.Universidade Federal de Goiás2011-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa científicaapplication/force-downloadtext/htmlhttps://revistas.ufg.br/vet/article/view/538010.5216/cab.v12i3.5380Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 12 No. 3 (2011); 427-434Ciência Animal Brasileira / Brazilian Animal Science; v. 12 n. 3 (2011); 427-4341809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/5380/9667https://revistas.ufg.br/vet/article/view/5380/9668Borosky, Julian Cristinada Rocha, Marco Antonioda Silva, Caio AbércioBridi, Ana MariaMonteiro, Roberta Abramiinfo:eu-repo/semantics/openAccess2012-07-01T14:38:07Zoai:ojs.revistas.ufg.br:article/5380Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:20.666611Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
