Strategies of signalization of pork quality to final consumer

A suinocultura destaca-se na economia brasileira. Contudo, avaliando-se o consumo interno da carne suína in natura, observa-se uma estagnação em patamares baixos. O artigo tem como objetivo analisar as principais iniciativas adotadas pelo Sistema Agroindustrial (SAG) da carne suína no Brasil visando sinalizar qualidade aos consumidores. Devido à marcante assimetria de informações, ressalta-se a importância da organização da cadeia produtiva, melhor direcionando esforços para a expansão do mercado interno. Este trabalho sugere ações visando aprimorar a coordenação deste SAG com vistas à melhoria na qualidade da carne ao consumidor e à redução da informalidade.Swine production plays an important role in Brazilian economy. Nevertheless, internal pork meat consumption shows a tendency to maintain low levels. The present article analyses the key initiatives of the Pork Agro-Industrial Chain in signaling quality to the consumers. The presence of significant information asymmetry highlights the importance of organizing the productive chain through a vertical association, better guiding the efforts towards internal market expansion. This paper suggests different actions aiming a better coordination of this productive chain to assure higher levels of meat quality to consumer and the reduction of informality

Organic selenium increases PHGPx, but does not affect quality sperm in raw boar semen

This study assessed the effects of feeding organic selenium (Se) on sperm morphology, motility, membrane integrity and lipidic peroxidation, also on sperm ATP and phospholipid hydroperoxide glutathione peroxidase (PHGPx) in raw semen of mature boars. Twelve boars were divided into three groups: Control, 0.3 ppm sodium selenite, Inorganic, 0.5 ppm sodium selenite and Organic, 0.5 ppm Se yeast for 11 weeks. Organic diet presented a higher total sperm number (P<0.05) when compared to the inorganic treatment; however, no difference was observed regarding volume, sperm concentration, number of cells with plasma and/or acrosomal membrane integrity, membrane mitochondrial potential, ATP assay and Se concentration in seminal and blood content. Also, no difference was observed on motility parameters, sperm morphology and membrane peroxidation, however, PHGPx was influenced (P<0.05) in organic treatment. Thus organic Se feeding influenced none of the analyzed seminal characteristics in raw semen, except for PHGPx and total number of sperm.This research was supported by FAPESP (Grant numbers 07/55613-6 and 08/55059-1), Alltech Inc., Vet life Veterinary Products and Agroceres Multimix Nutrição Animal Ltda
