En la producción avícola los problemas respiratorios bacterianos son causa de pérdidas económicas por disminución producción, aumento del costo tratamiento con antibióticos y primera muerte en gallinas ponedoras. La presencia patógenos implica una distribución las unidades su identificación pruebas bioquímicas permite caracterización a nivel especie adecuado. El objetivo presente estudio fue id...

Peritonitis is the major disease problem of laying hens in commercial table egg and parent stock operations. Despite its importance, the etiology and pathogenesis of this disease have not been completely clarified. Although avian pathogenic Escherichia coli (APEC) isolates have been incriminated as the causative agent of laying hen peritonitis, Gallibacterium anatis are frequently isolated from...

Abstract Purslane is a widespread wild vegetable with both medicinal and edible properties. It highly appreciated for its high nutritional value also considered as high-quality feed resource livestock poultry. In this study, Sanhuang broilers were used to investigate the effect of feeding purslane diets on growth performance in their gut microbiota. A total 48 birds good uniform weight selected...

The emerging microbial source tracking (MST) methodologies aim to identify fecal contamination originating from domestic and wild animals, and from humans. Avian MST is especially challenging, primarily because the Aves class includes both domesticated and wild species with highly diverse habitats and dietary characteristics. The quest for specific fecal bacterial MST markers can be difficult w...

A range of feed supplements, including antibiotics, have been commonly used in poultry production to improve health and productivity. Alternative methods are needed to suppress pathogen loads and maintain productivity. As an alternative to antibiotics use, we investigated the ability of biochar, bentonite and zeolite as separate 4% feed additives, to selectively remove pathogens without reducin...
