| Maremmana is a local Italian breed reared in southern Tuscany and northern Latium. Twenty-two young bulls were reared in pasture system with concentrate supply (PSCS), whereas 20 young bulls were reared in feedlot intensive system (IS) in order test differences between meat typologies. The bulls were slaughtered at 18 months old. The performances at slaughtering were similar between finishing systems. IS bull meat has shown higher cooking loss than PSCS bull meat (p < 0.001), higher moisture content (p < 0.01), and fat (p < 0.001), and lower crude protein (p < 0.001). The SFA, MUFA and PUFA percentage were similar between meat typologies; whereas if considered in mg per 100 gr of muscle MUFA and SFA content was higher in PSCS... |

| Superovulatory response, production and embryo quality and the effects of seasonal changes on embryo production of Nellore cows fed on either linseed (n-3) or canola seeds (n-6) were evaluated. Sixteen Nellore cows (550 ± 48.0 kg) were fed on three diets: control diet (CON), diet with linseed (LIN) and diet with canola seed (CAN) during four seasons. There was no difference in superovulatory response and in total corpora lutea produced when diets are taken into consideration. The number of cows that responded to superovulatory treatment was higher in the winter (93.8%) than in the summer (62.5%). No difference with regard to the three diets existed on the average number of total structures (6.20, 4.96 and 6.50), unfertilized structures (2.53, 1.17 and... |

| For this research 48 male lambs were divided in randomized blocks in a factorial design, having as factors sexual condition (castrated or uncastrated) and time on feed (36 or 78 days). High grain diet was monitored daily to measure the performance of the animal nutrition. The characteristics of the carcass and meat were taken for the fatty acids profile and sensorial analysis. The effect of the factors as sexual condition and time on feed, and the interaction between them, were evaluated by analysis of variance using the GLM procedure of SAS software and the treatment averages were compared by Student's T test. The uncastrated animals presented greater weight gain and dry matter intake, better feed efficiency, and larger loin area. More time on feed... |

| The aim of this study was to evaluate the effects of different aging times on the meat characteristics from young Murrah buffaloes slaughtered at 20–24 months of age (experiment I; n=10) and Murrah buffalo heifers slaughtered at 32-36 months of age (experiment II; n=10), with the purpose of determining the best aging time to tenderize meat from both experiments. Samples of the longissimus thoracis muscle from buffaloes slaughtered at each age were aged for 7, 14, and 21 days (0±1°C). After this period, analysis of cholesterol, pH, cooking loss, shear force, myofibrillar fragmentation index, meat color, and fatty acid profile was performed. Aging greatly improved the tenderness (p < 0.05) but caused a change in color (p < 0.05), which, even without... |

| This study aimed to evaluate the inclusion of Brazil nut oil in diets for breeder cocks on performance, semen analyses, biochemical serum profile and testicular morphology. Forty-two Rhode Island Red breeder cocks with 40 weeks of age were used. The experimental design was completely randomized consisting of seven levels of Brazil nut oil (0; 0.30; 0.60; 0.90; 1.20; 1.50 and 1.80%) in the diets. Data collected were evaluated by polynomial regression. Differences (p < 0.05) were detected in feed conversion, semen volume, motility, vigor, pH, swirling and concentration, in which the inclusion of Brazil nut oil in the diets improved the reproductive performance. Differences (p < 0.05) were also detected in the biochemical serum profile (triglycerides,... |

| Consumers today are increasingly more demanding regarding their food, seeking healthier and better quality products, and in this context animal nutrition plays a key role. The meat composition can be altered by animal feed itself, being that lipid profile may directly contribute to consumer health, reducing the predisposition of developing cardiovascular diseases, main cause of mortality in the world. Thus, the aim of this study was to assess the effect of dietary feed restriction in Santa Inês lambs on their intramuscular, intermuscular, and subcutaneous fat profile, fat profile of the longissimus thoracis et lumborum (LTL) muscle, and the total meat lipids and cholesterol. Three groups of lambs were subjected to diets: without restriction (WR), and 30... |

| Due to the fact that domestic consumers prefer low fat meat, the lamb production system in Spain is based on slaughtering low weight animals (12 to 24 kg). Lambs in other European countries are slaughtered at higher weights because consumers prefer more intense flavored and fatter meat. Based on evidence that slaughter weight affects fat characteristics, the effect of slaughtering weight on the fatty acid profile of omental (OM), mesenteric (MES), kidney knob (KK), subcutaneous (SC), intermuscular (IN) and intramuscular (IM) fat in Lacha breed lambs was studied. Forty-two male Lacha lambs were raised and slaughtered at 12 (L12), 24 (L24) and 36 kg (L36) live weight. L12 lambs were fed only on mother's milk until slaughter, one month old. L24 and L36 lambs... |

| ABSTRACT The aim of this study was to modify the fatty acid profile of yogurt from sheep milk by the inclusion of different concentrations of palm oil into their diet. Thus, thirty-six sheep during lactation were separated in four groups with nine animals each, as described below: the group T0 (0%); the group T2 (inclusion of 2% of palm oil); the group T4 (inclusion of 4% of palm oil) and the group T6 (inclusion of 6% of palm oil). After 60 days of the supplementation, milk samples were collected and yogurt was produced, which was evaluated regarding the concentration of saturated fatty acids (SFA), monounsaturated fatty acids (MFA), and polyunsaturated fatty acids (PFA). A significant reduction (p<0.05) in most SFA and a significant increase... |

| The purpose of this study was to evaluate the chemical, physiological and genetic differences in seeds of cactus of the Cereus genus (mandacaru) cultivated in the Northeast (Picos, State of Piauí) and Southern (Maringá, State of Paraná) regions of Brazil. Over a period of eight days, temperatures of 25°C and 30°C were equally efficient for the germination of all the seeds. Oleic acid (C18:1) was the most common fatty acid found in the seeds collected in the Southern (41%) and Northeast (45.5%) regions. The analysis of lipases indicated that seeds from Maringá have high mean observed and expected heterozygosities and that seeds from Picos have a higher number of alleles per loci. Therefore, the seeds of mandacaru from the semiarid region of Northeast as... |

| Contents of proteins, carbohydrates and oil of seeds of 57 individuals of Vochysiaceae, involving one species of Callisthene, six of Qualea, one of Salvertia and eight of Vochysia were determined. The main nutritional reserves of Vochysiaceae seeds are proteins (20% in average) and oils (21. 6%). Mean of carbohydrate contents was 5. 8%. Callisthene showed the lowest protein content (16. 9%), while Q. cordata was the species with the highest content (30% in average). The contents of ethanol soluble carbohydrates were much higher than those of water soluble carbohydrates. Oil contents lay above 20% for most species (30. 4% in V. pygmaea and V. pyramidalis seeds). The predominant fatty acids are lauric (Q. grandiflora), oleic (Qualea and Salvertia) or acids... |

| ABSTRACT This study evaluated the chemical composition and antioxidant activity of fatty acids from the marine red algae Pterocladiella capillacea (S. G. Gmelin) Santelices & Hommersand 1997 and Osmundaria obtusiloba (C. Agardh) R. E. Norris 1991. The gas chromatography mass spectrometry (GC-MS) identified nine fatty acids in the two species. The major fatty acids of P. capillacea and O. obtusiloba were palmitic acid, oleic acid, arachidonic acid and eicosapentaenoic acid. The DPPH radical scavenging capacity of fatty acids was moderate ranging from 25.90% to 29.97%. Fatty acids from P. capillacea (31.18%) had a moderate ferrous ions chelating activity (FIC), while in O. obtusiloba (17.17%), was weak. The ferric reducing antioxidant power (FRAP) of... |

| Twenty hair (Pelibuey x Katadin x BlackBelly) and 20 wool (Rambouillet x Criollo) lambs were fattened in an intensive feeding system to reach 40kg body weight at ten months of age. The yield of lamb sides and back fat (51.9%, 2.5mm vs. 47.0%, 2.3mm) were greater in wool lambs. Meat pH was not different between phenotypes but meat temperature was higher during the first hours postmortem in wool lamb sides (27, 23, and 20, vs. 24, 20, and 17ºC). Protein content in meat from the neck (braquicephalic and esternocephalic muscles) and loin (Longissimus lumborum muscle) were higher in hair lambs (21.1 and 20.4 vs. 19.7 and 19.3 %), while moisture of the same muscles was higher in wool lambs (75.6 and 75.9 vs. 73.6 and 74.3%). Ash content was similar in both... |

| The type of diet consumed by individuals has been associated with the development of some chronic diseases, including cardiovascular disease (CVD), cancer, diabetes, and others. Populations that consume diets rich in fruits and vegetables and drink wine in moderation, as the Mediterranean, have a higher life expectancy and less chronic diseases than other occidental populations. We carried out an intervention study in humans to evaluate the effect of a Mediterranean diet (MD), an Occidental diet (OD) and their supplementation with red wine, on biochemical, physiological and clinical parameters related to atherosclerosis and other chronic diseases. For 3 months, two groups of 21 male volunteers each, received either a MD or an OD; during the second month,... |
