Resumo: Data from 1372 boars of Landrace (614). Largo White (515) and Duroc (243) breeds on progeny test at the Estação de Avaliação de Suínos (Swine Evaluation Station), in Concórdia, SC, Brazil, were analysed from 1975 to 1981 to evaluate the effects of environmental factors and time trends on performance and carcass traits. The first degree (linear) for lean: fat ratio, carcass weight, loin-eye area and ham weight, carcass length, and food conversion within the Duroc breed, average daily gain, backfat thickness, carcass yield, and food conversion within Landrace and Large White breeds were the best fitting polynominals to year effects. The seasonal effect, hot weather (October-March) minus cold weather (April-September) differences (P < 0.05) in food conversion, carcass length, carcass yield and ham weight were 0.05, -0.58 cm, 0.24% and 0.13 kg. Differences between breeds for backfat thickness and carcass weight were not significant (P > 0.05). The Duroc breed showed the lowest (P < 0.05) carcass length. In general, the Large White breed was better for performance, and the Landrace for carcass traits. The time trends effectively showed no evidence of generation of progress on the traits evaluated, suggesting the adoption of more efficient methods of testing and selection to obtain progress in a shorter time.

Analisaram-se os efeitos de ano, época, raça e suas interações, e da idade no início do teste, como covariável sobre as características: ganho de peso diário (GPD), conversão alimentar (CA), peso de carcaça (PC), comprimento de carcaça (CC), rendimento de carcaça (RTO), espessura de toucinho (ET),.área de olho-de-lombo (AOL), peso de pernil (PP), e relação carne-gordura (RCG). Também estudou-se a tendência de cada característica, no período, pela decomposição do efeito de ano, mediante regressão polinomial. O efeito de ano foi significativo (P < 0,05) para todas as características. A época do ano influenciou (P < 0,05) a CA, o CC, o RTO e o PP. Não houve diferenças (P  > 0,05) entre raças para ET e PC. O CC foi inferior (P < 0,01) na raça Duroc e maior (P < 0,01) na Landrace. De modo geral, a raça Large White apresentou-se melhor nas características de desempenho, e a Landrace, nas de carcaça. As tendências observadas não evidenciaram, efetivamente, a realização do progresso nas características avaliadas, o que sugere a adoção de métodos mais eficientes de testagem e seleção para se alcançar progresso em menor tempo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCosta, Cláudio NápolisFávero, Jerônimo AntonioLeitão, Geísa Ribeiro2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16425Pesquisa Agropecuaria Brasileira; v.20, n.12, dez. 1985; 1443-1450Pesquisa Agropecuária Brasileira; v.20, n.12, dez. 1985; 1443-14501678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16425/10687info:eu-repo/semantics/openAccess2014-04-16T19:48:26Zoai:ojs.seer.sct.embrapa.br:article/16425Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:48:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
