| The addition of antioxidants to broiler diets has been shown to enhance their antioxidant status. Since boldo (Peumus boldus Mol.) leaves contain highly antioxidant molecules, a dried extract of boldo (DEB) was added to broiler diets to improve "in vivo" antioxidant tissue status and to favor animal growth. A DEB standardized for antioxidant content was prepared and added to poultry diets at three different levels (low-DELB, medium-DEMB, and high-DEHB) for a period of 6 weeks. A single negative control (no added antioxidant) and one positive control (supplementation with 200 mg/kg vitamin E) were used. Plasma antioxidant capacity (PAC), thiol content (GHS), and basal and induced lipoperoxidation of liver, leg and breast tissues were determined in birds at... |

| The Plectranthus genus comprises several species generally referred to as boldo, which are highly used in popular medicine due to their anti-dyspeptic, analgesic and digestion-stimulating properties. The amount of natural active principles can vary greatly in the related genotypes, which may lead to the inappropriate use of these plants. This work aimed to analyze the interspecific diversity among four species of the Plectranthus genus (P. grandis, P. barbatus, P. neochilus and P. amboinicus) and the intraspecific diversity of P. barbatus collected from different places in southern Brazil, by means of the RAPD technique. A higher genetic similarity was observed between the P. neochilus and P. amboinicus species (80%), followed by P. grandis and P. barbatus... |
