Última Effects of supplementing broiler diets with a combination of fermented red ginseng marc powder and red-koji on thigh meat quality of broiler chick during storage Animal Sciences Ji, Joong Gu; Choi, In Hag. We assessed the effects of supplementing broiler diets with a combination of fermented red ginseng marc powder and red-koji on thigh meat quality of broiler chick during storage. Broilers (n = 120) were randomly assigned to one of two groups: control or treatment with 1% fermented red ginseng marc combined with red-koji. There were four replicates per group, each comprising 15 birds (10 male and 5 female). Neither the dietary supplementation group nor the number of storage days had a significant (p > 0.05) effect on meat pH. However, TBARS, a measure of lipid oxidation, was significantly affected (p < 0.05) by both the number of storage days and the dietary supplementation, with reduced TBARS activity noted in the treatment group after 7 days of...

Bras. Med. Vet. Zootec. Rocha,J.S.R.; Barbosa,V.M.; Lara,L.J.C.; Baião,N.C.; Cançado,S.V.; Lana,A.M.Q.; Pompeu,M.A.; Vasconcelos,R.J.C.; Machado,A.L.C.; Miranda,D.J.A.; Fernandes,M.N.S.; Mendes,P.M.M.. O presente experimento foi conduzido em lote de matrizes Cobb desde 46 até 60 semanas de idade. Os tratamentos foram definidos pelas dietas (com e sem adição de 6ppm de cantaxantina na dieta das matrizes) e pelos períodos de armazenamento dos ovos (três e sete dias), em delineamento inteiramente ao acaso, em arranjo fatorial 2x2 (duas dietas x dois períodos de armazenamento). A cantaxantina dietética elevou o escore de cor da gema de sete para 14. O armazenamento dos ovos por sete dias prejudicou a qualidade dos ovos, promoveu oxidação de ácidos graxos da gema e retardou o desenvolvimento embrionário.

Exposure to stress induces a cluster of physiological and behavioral changes in an effort to maintain the homeostasis of the organism. Long-term exposure to stress, however, has detrimental effects on several cell functions such as the impairment of antioxidant defenses leading to oxidative damage. Oxidative stress is a central feature of many diseases. The lungs are particularly susceptible to lesions by free radicals and pulmonary antioxidant defenses are extensively distributed and include both enzymatic and non-enzymatic systems. The aim of the present study was to determine lipid peroxidation and total radical-trapping potential (TRAP) changes in lungs of rats submitted to different models of chronic stress.

Aliment. Marangoni,Cristiane; Moura,Neusa Fernandes de. Four formulations of Italian salami type were produced: without antioxidants; with essential oil of coriander essential oil (0.01%); with BHT (0.01%); and with Coriander essential oil and BHT (0.005 and 0.005%). The antioxidant activity of salamis was evaluated by the lipid oxidation, through the techniques of peroxide number and TBARS. The salami with the coriander essential oil exhibited reduction in lipid oxidation by increasing the shelf life of the product. The salami with the coriander essential oil and BHT showed no synergism between the antioxidants. The salami using BHT presented less antioxidant activity than that of the salami using coriander essential oil.
