【摘要】：目的研究不同饲粮营养水平对巴马香猪和长白猪机体矿物元素沉积的影响。方法选取巴马香猪和长白猪共32头(每品种16头),随机分为4组(n=8),分别为长白猪饲喂美国国家研究委员会(NRC)饲粮组、长白猪饲喂中国猪饲养标准(GB)饲粮组、巴马香猪饲喂NRC饲粮组、巴马香猪饲喂GB饲粮组。试验从130日龄开始,至出栏时结束,采集血液、肝脏和肌肉样品,分析其中Cu、Mn、Zn、Fe、Mg、Ca和Na的含量。结果 (1)巴马香猪血浆和股二头肌中Cu含量,肝脏、股二头肌和腰大肌中Zn和Fe含量均显著高于长白猪(P0.05)。(2)与GB饲粮相比,NRC饲粮可显著提高血浆Fe浓度和肝脏Zn、Fe含量(P0.05)。(3)饲粮与品种对机体Na、Fe和Mn含量存在显著互作效应(P0.05),GB饲粮可提高巴马香猪背最长肌Fe含量、长白猪肝脏Na含量和腰大肌Mn含量,NRC饲粮可提高长白猪背最长肌Fe含量、巴马香猪肝脏Na含量和腰大肌Mn含量。(4)除Mg元素外,肝脏中其他元素含量均显著高于骨骼肌中的含量(P0.05);背最长肌中所有元素含量均显著高于股二头肌和腰大肌中的含量(P0.05)。结论品种和饲粮对机体矿物元素含量存在不同程度的影响,机体不同部位之间矿物元素含量也存在差异。
[Abstract]:Objective to study the effect of different dietary nutrition levels on mineral element deposition in Bama Xiang pigs and Landrace pigs. Methods 32 Bama Xiang pigs and Landrace pigs were selected and randomly divided into 4 groups, fed by Landrace pigs. The National Research Council of the United States, NRC, Landrace pigs were fed with Chinese pig feeding standard (GB) diet group, Bama Xiang pig with NRC diet group and Bama Xiang pig with GB diet group. The experiment began at 130 days old and ended at the end of the experiment. Blood, liver and muscle samples were collected. The contents of Cu and Na in the plasma and biceps femoris of Bama pig were analyzed. The contents of Zn and Fe in biceps femoris and psoas major muscle were significantly higher than those in Landrace pig (P 0.05. 0. 2) compared with GB diet, NRC diet could significantly increase plasma Fe concentration and liver Zn Fe content (P 0. 05, P 0. 05, P 0. 05, P < 0. 3). There was a significant interaction effect between diet and variety on the content of Na, Fe and mn. The content of Fe in the longissimus dorsi muscle of Bama Xiang pig was increased by P0.05 / GB diet. The content of Na in liver and mn content in psoas major muscle of Landrace pig increased Fe content of longissimus dorsi muscle in Landrace pig, Na content in liver of Bama pig and mn content in psoas major muscle. The contents of other elements in liver were significantly higher than those in skeletal muscle, and all elements in longissimus dorsi muscle were significantly higher than those in biceps femoris and psoas major muscle. There are also differences in mineral elements between different parts of organism.
