Dietary Supplementation of Oregano and Sage Dried Leaves on Performances and Meat Quality of Rabbits
Luca Rotolo Francesco Gai Silvana Nicola Ivo Zoccarato Alberto Brugiapaglia Laura Gasco 《农业科学学报》2013,12(11):1937-1945
The aim of this research was to evaluate the dietary supplementation 1% (w/w) of oregano and sage dried leaves on performances and meat quality of broiler rabbits. A feeding trial, which lasted 48 d, was carried out on 105 male Bianca Italiana rabbits randomly divided in seven groups and fed ad libitum. At the end of the trial ten animals per group were slaughtered and samples of dorsal muscle were taken in order to perform laboratory analysis. Mortality rate did not statistically differ between groups. Growth performances of animals fed diets supplemented with aromatic plants were higher (P〈0.05) than those of animals of control group, whereas carcass parameters were not affected by treatments excepting for the slaughter weight that showed the same trend as growth performances. Meat quality traits, oxidative lipid stability and fatty acid proifle were not inlfuenced by aromatic plant supplementation. In conclusion, oregano and sage in form of dried leaves can be used in rabbit without adverse effects on performance, carcass characteristics and meat quality traits. 相似文献

土壤干旱与柿叶片膜脂及脂质过氧化的关系 总被引:3,自引:0,他引:3
在不同灌水条件下,对盆栽柿幼树叶片组织相对含水量,细胞透性,超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性,膜脂脂肪酸组分和脂质过氧化作用产物——丙二醛(MDA)含量进行测定,结果表明:当水势Ψ_S下降时,细胞透性(PERM)增大,SOD和CAT活性下降,脂质过氧化作用增强,膜脂中不饱和脂肪酸含量下降,饱和脂肪酸含量升高。试验证明:土壤水势(?)_S=-3.80±0.47bar,各指标变化最明显。本试验条件下,幼柿叶片SOD活性,CAT活性,MDA含量,PERM,不饱和脂肪酸指数(IUFA)与组织相对含水量(RWC)和土壤水势(Ψ_s)间具显著相关关系。 相似文献

不同贮藏条件鸡蛋的脂类过氧化作用 总被引:4,自引:0,他引:4
本文以TBA光度法分析了不同贮藏条件下鸡蛋脂类的过氧化作用,并分析了温度、氧对过氧化作用的影响。结果表明,在贮藏条件下,鸡蛋蛋黄中伴有明显的脂类过氧化过程。脂类过氧化物(LPO)的水平随贮藏时间的延长而不断增加(P<0.01),但蛋清中的LPO在贮藏过程中没有明显的变化。低温和缺氧可明显抑制鸡蛋脂类的过氧化作用(P<0.01)。 相似文献

A polyphenol-rich extract from the seeds of fenugreek was evaluated for its protective effect against hydrogen peroxide(H2O2)-induced oxidation in normal and diabetic human erythrocytes (RBCs). RBCs, preincubated with increasing amounts of fenugreek seed extract and challenged with H2O2, were analyzed for hemolysis and lipid peroxidation. RBCs from diabetic subjects were more susceptible to oxidative hemolysis and lipid peroxidation than those from normal subjects. However preincubation with the polyphenol-rich extract significantly reduced the oxidative modifications in both the groups. The inhibition of lipid peroxidation was concentration-dependent up to 100 l of extract, which contained 0.75mM gallic acid equivalent (GAE) of phenolic compounds. These findings demonstrate the potent antioxidant properties of the fenugreek seeds. 相似文献

采用恒温热重法测定了在空气中,0.1MPa,673K到973K下预氧丝(即预氧化聚丙烯腈纤维)原位炭化无粘结剂C/C复合的氧化失重率;并利用扫描电镜分析了这种复合材料氧化前后的结构,氧化动力学测定结果表明:该材料在氧化开始时,其氧化速率随时间的增长而增大,然后随时间的延长而减小,并趋向恒定,研究表明:该材料中预氧丝与基体炭界面结合处是空气中氧的扩散通道,杂质为空气中氧的吸附起到了有附活性中心的催化 相似文献

旨在研究日粮中添加酵母硒对白羽肉鸡宰后成熟过程中线粒体氧化损伤及细胞凋亡的影响。以饲喂不同酵母硒添加量日粮肉鸡的胸肉为研究对象,测定宰后成熟过程中鸡肉线粒体氧化损伤程度、抗氧化酶活性、Caspase-3和Caspase-9活性及肉嫩度的变化。结果表明,宰后成熟过程中,酵母硒饲喂组活性氧(reactive oxygen species,ROS)水平、线粒体膜通透性转换孔(mitochondrial permeability transition pore,MPTP)开放程度、线粒体膜通透性、Caspase-3以及Caspase-9活性均显著低于对照组(P<0.05);硒含量、胞浆细胞色素c (cytochrome c,Cyt-c)还原水平、线粒体膜电位及谷胱甘肽过氧化物酶(glutathione peroxidase,GSH-Px)活性显著高于对照组(P<0.05)。酵母硒饲喂组总抗氧化能力(total antioxidant capacity,T-AOC)在宰后成熟初期显著高于对照组(P<0.05),而在其他时间点虽有提高但差异不显著(P>0.05)。此外,酵母硒饲喂组肌原纤维小片化指数(myofibrillar fragmentation index,MFI)在宰后成熟过程中显著低于对照组,相对应的剪切力显著高于对照组(P<0.05)。由此可见,饲喂酵母硒通过降低鸡肉线粒体的氧化损伤进而抑制了细胞凋亡,最终减弱了肌原纤维蛋白的降解。 相似文献

High‐fat (HF) or high‐carbohydrate (HC) diets (30% fat, 18.9% carbohydrate; HF and 10% fat, 46.3% carbohydrate; HC) and lengths of adaptation were investigated in cats (Felis catus; 10 ± 2 months, 3.6 ± 0.3 kg). Cats randomly received each treatment for 14 days in a crossover design with a 14‐day washout period between each diet. Three 22‐h indirect calorimetry studies were conducted after acute (day 0), semichronic (day 4) and chronic (day 13) dietary exposure. Blood samples were collected after a 24‐h fast on days 1, 5 and 14. When cats consumed the HC and HF diet, oxidation of the restricted nutrient exceeded intake while oxidation of the nutrient in excess matched intake. Mean max energy expenditure (EE) of cats consuming the HF and HC diet were 107 and 102 kcal/kg0.67/day and occurred at a mean of 4 and 12 h post‐feeding respectively. Maximal fat (0.90 g/h) and carbohydrate (carbohydrate; 1.42 g/h) oxidation were attained at 26 min and 10.4 h post‐feeding respectively. The changes observed in macronutrient oxidation and EE suggest that cats adapt whole‐body nutrient metabolism in response to changes in dietary macronutrient content, but may require longer than 14 day to adapt to a macronutrient that is present at a lower concentration in the diet. 相似文献
