| The present work evaluated and compared the lipid oxidation of charque, taken from, the semi-tendinosus muscle of animals from the Nelore breed (Bos taurus indicus), supplemented with α-tocopherol. Charque was produced submitting the samples to salt moisture, salt drying and exposition to the sun for dehydration until water activity values (Aw) reached 0.75. The statistical analysis of the results showed that there were no significant differences in the values of cholesterol, total lipids, fatty acids and substances relative to tiobarbituric acid (TBARS) and tocopherol as the samples were controlled and supplemented, respectively. Despite this, the values of TBARS and cholesterol were lower in the samples with the supplement of α-tocopherol. The... |

| Os objetivos deste trabalho foram avaliar o perfil de ácidos graxos e o teor de colesterol em mortadelas elaboradas com diferentes óleos vegetais. Nove tratamentos de mortadela foram elaborados com quatro diferentes óleos vegetais (canola, linhaça, oliva e soja), em dois níveis de substituição (50% e 100%). Os ácidos graxos e o teor de colesterol foram separados e identificados por cromatografia gasosa. Houve predominância dos ácidos graxos oleico, linoleico e palmítico. O teor de ácidos graxos saturados foi menor nos produtos que continham óleos vegetais. A relação PUFA/SFA foi menor no tratamento controle, enquanto que o maior valor foi observado no tratamento com 100% de óleo de linhaça. Os teores de colesterol encontrados foram semelhantes entre todos... |

| Dietary vitamin supplementation decrease stress caused by high stocking density, and boosts immunological system of farmed fish. A studied was carried out to determine vitamin A requirements of Nile tilapia (Oreochromis niloticus) in an all male group (13.8 ± 1.2 g) and a mixed sex population (9.8 ± 2.3 g). Fish stocked in 100-L plastic aquaria (26.0 ± 1.0ºC) were fed to near satiety, twice a day, seven days a week, during 75 days with vitamin A-free, semi-purified diets supplemented with 0; 600; 1,200; 1,800; 2,400; 3,000; 3,600; 4,200; 4,800 and 5,400 International Units (IU) of retinyl palmitate (30% vitamin A) per kg of diet in a completely randomized experimental design, factorial arrangement 2c10 (n = 4). Deficiency signs of vitamin A were observed... |
