Resumo: | Currently, two defects in poultry breasts termed Wooden Breast (WB) and White Striping (WS) have been reported in slaughterhouses. These defects may be associated with the accelerated growth of the birds, management, density in the aviary, and both weight and age at slaughter. Although the health of the affected birds is not impaired, these myopathies cause carcass condemnation and economic losses to slaughterhouses, since the breasts of these chickens, considered to be prime cuts in the poultry industry, have to be discarded. This paper reports on the economic losses and factors associated with carcass condemnation caused by white striping (WS) and wooden breast (WB) in broilers from a federally inspected slaughterhouse. Twelve flocks, totaling 207,000 slaughtered broilers, were assessed as to weight and age at slaughter, and stocking density and carcass condemnations due to these two myopathies were also evaluated. Economic losses were estimated by the price of poultry breast at the firm level, around U$ 19,12 per kilo, amounting to daily losses of up to U$ 70,632.00, given that approximately 0.8% of the chicken breasts were condemned. Heavier broilers had a larger condemnation rate due to WS and WB, and so did those reared at a smaller density, due probably to their better access to water and feed, which contributed to weight gain and consequent condemnation, resulting in losses that could affect the entire poultry sector. |

Embora não haja comprometimento da saúde das aves afetadas, estas miopatias causam condenações e prejuízos aos abatedouros devido ao não aproveitamento do peito destes frangos, considerado um corte nobre na indústria avícola. Neste trabalho são relatados os prejuízos econômicos e fatores associados às condenações por White Striping (WS) e Wooden Breast (WB) em frangos de corte em um abatedouro sob Inspeção Federal. Foram acompanhados 12 lotes totalizando 207.000 aves abatidas, registrando-se dados como peso e idade ao abate, densidade nos galpões de criação e condenações por estes dois defeitos. As perdas econômicas foram calculadas a partir do valor do peito de frango na empresa, em torno de R$ 5,90 o quilograma, gerando prejuízos de até R$ 21.800,00 ao dia, já que cerca de 0,8% dos peitos foram desqualificados devido à estas alterações. Aves mais pesadas apresentaram maior condenação por WS e WB, bem como quando criadas em menor densidade, provavelmente devido ao melhor acesso a água e ração, contribuindo para aumento de peso e consequente condenações por estas miopatias, impactando em prejuízos que podem ser extrapolados para todo o setor avícola.UEL2018-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2886410.5433/1679-0359.2018v39n2p887Semina: Ciências Agrárias; Vol. 39 No. 2 (2018); 887-892Semina: Ciências Agrárias; v. 39 n. 2 (2018); 887-8921679-03591676-546Xreponame:Semina.
