This study investigated the effect of feeding vitamin E, vitamin C, and two sources of vegetable oil on immune response and meat quality of broilers. A total of 320 one-day-old chicks were used in a completely randomised design with eight treatments arranged as a 2 × 2 × 2 factorial with two levels of vitamin E (0 and 200 mg/kg), two levels of vitamin C (0 and 1000 mg/kg), and two sources of vegetable oil (soybean and canola). Dietary supplementation of either vitamin E or C increased (P < 0.05) secondary humoral response, whereas oil sources had no significant effect. Broilers fed soybean oil had lower cellular response to the phytohemagglutinin skin test than those fed canola oil in diet, and supplementation of vitamin E increased cellular immune response. However, fat, cholesterol and pH of meat were not affected by source of oil or antioxidants, lipid oxidation was higher (P < 0.05) in thigh and breast meat of broilers fed soybean oil than canola oil. Dietary supplementation of vitamin E decreased (P < 0.05) lipid oxidation in thigh and breast of broilers fed diet containing soybean oil, without any effect on meat oxidation of those fed canola oil. Dietary supplementation of vitamin C increased lipid oxidation in thigh meat of broilers (P < 0.05). It can be concluded that inclusion of soybean oil to the diet, compared with canola oil, increased need for antioxidant. Vitamin E had beneficial effects on immune response and reduced meat lipid oxidation; nonetheless future studies should explore the antioxidant effect of vitamin C in stored meat.

Cattle Meat

Meat is the most valuable livestock product since it is one of the main sources of protein for human consumption. Meat quality can be evaluated according to the following parameters: pH, amount of lactic acid, volatile fatty acids, bounded water, solubility of proteins, color, and tenderness. The meat composition and physical properties of muscles have been characterized for ensuring improved eating quality. Thus, the purpose of this paper was to review the major chemical compositional and physicochemical properties of meat and, at the same time, its quality attributes and factors that affect quality of meat. A number of structural features of meat as connective tissue, muscle fibers, and tendon that attaches the muscle to the bone are visible in joint meat examined through naked eyes. Water is quantitatively the most important component of meat comprising up to 75% of weight. Meat is also composed of amino acids, fatty acids, vitamins, minerals, and other important ingredients. Quality factors perceived by consumers are related to sensory attributes (e.g., color, tenderness, and flavor), nutritional properties (e.g., calories, vitamins’ content, and fatty acids’ profile), and appearance (e.g., exudation, marbling, and visible amount of fat). However, fresh meat quality can be defined instrumentally including composition, nutrients, color, water-holding capacity, tenderness, functionality, flavors, spoilage, and contamination. Visual inspection based on sensory quality attributes and different chemical methods are used to analyze meat quality. Other methods such as computer vision and imaging spectroscopy, gas chromatographic analysis, near-infrared technology, dual-energy X-ray absorptiometry, and computerized tomography scanning are also used in the meat industry. So, the aim of the present review is to review quality characteristics of cattle meat and its composition constituents.

ObjectivesThe objective was to evaluate the effect of supplementing α- and γ-tocopherol vitamin E isoforms with corn oil and tallow on carcass characteristics and meat quality of pigs grown to heavier weights (>150 kg).Materials and MethodsIndividually fed pigs (n = 72; 36 barrows, 36 gilts; 28.55 ± 1.16 kg) were randomly assigned to 12 dietary treatments in a 2 × 6 factorial arrangement. Fat treatments were tallow and corn oil (5?). The vitamin E treatments included four levels of α-tocopheryl-acetate (ATA; 11, 40, 100, and 200 ppm) and two levels of mixed tocopherols (primarily γ-tocopherol; 40 and 100 ppm). Pigs were humanely slaughtered at approximately 150 kg. 45 min pH was taken at the 10th rib. After 24 h chill (4°C), carcass measurements were taken (carcass length, backfat depth at first rib, last rib, 10th rib and last lumbar, loin muscle area, and 24 h pH at the 10th rib). In addition, wholesale weights from the Boston butt (IMPS #406), shoulder picnic (IMPS #405), loin (IMPS #412), and belly (IMPS #408) and spareribs were recorded. Furthermore, bellies were divided into eight sections and the average depth was taken at each section and the vertical and lateral belly flex was measured. Drip loss was determined by suspending a 1.3cm chop at 4°C for 48 h and purge loss was determined from approximately 2kg vacuum packaged loin muscle sections at 0, 7, 14, and 30d. Objective (Hunter Lab Colorimeter XE Plus) and subjective (NPPC color, marbling and firmness scores) measurements were taken at the 10th rib. Data analysis were performed in SAS by least squares analysis of variance using the generalized linear model as a randomized complete block design. The individual pig served as the experimental unit and results were reported as least square means.ResultsThere were no differences in dressing percentage, 24 h pH, backfat depth, loin muscle area, primal cuts, purge loss, and drip loss between the two vitamin E isoforms. Fat treatments did not affect dressing percentage, 45 min and 24 h pH, backfat depth, loin muscle area, primal cuts, purge loss, drip loss as well as objective and subjective color. Although not significant (P = 0.07), pork from the γ-tocopherol pigs had a lower pH than the ATA treatment. The γ-tocopherol supplementation tended to have a lighter subjective color (P = 0.06) as well as increased L*, decreased a*, and increased the hue angle calculations at 7d shelf-life. The belly depth was greater (P = 0.01) along with higher lateral (P < 0.01) and a lower vertical (P < 0.01) flex for pigs fed tallow.ConclusionIn conclusion, feeding tallow to heavy weight pigs (150 kg) could improve belly firmness. Also, α-tocopherol did not improve shelf-life stability and γ-tocopherol could negatively affect subject and objective pork loin color.
