The present study was conducted to evaluate the effect of dietary mulberry(Morus alba L.) leaves powder(MLP) supplementation on meat quality of finishing pigs.A total of 40 Duroc×Landrace×Yorkshire pigs(initial body weight of(40.5±0.63) kg) were randomly allotted into two treatments,fed either with control diet or 15% MLP diet for 85 *** results showed that MLP diet decreased(P≤0.05) average daily gain(ADG) and increased(P<0.05) feed/gain ratio(F/G) in the finishing and whole *** diet also decreased(P<0.05) carcass weight,dressing percentage,last rib and average backfat ***,MLP diet increased(P<0.05) intramuscular fat(IMF) content,decreased(P<0.05) shear force,cooking loss and drip *** addition,MLP diet increased(P<0.05) total antioxidative capacity,glutathione peroxidase and tended(P<0.10) to increase total superoxide dismutase in *** longissimus thoracis,myosin heavy chain(MyHC) I and IIa mRNA levels were increased(P≤0.05) for MLP *** conclusion,15% MLP supplementation reduced the growth performance and carcass traits,but improved meat quality of finishing pigs possibly through the change of myofiber characteristics,enhancement of antioxidative capacity and increase of IMF.

试验选用60头初始体重为(88.16±8.03)kg的杜×长×大三元杂交育肥猪,分为4个处理组,采用2×2因子设计。试验日粮包括2个消化能水平(正常能量组:14.22 MJ/kg;高能组:16.21 MJ/kg,以10%椰子油替代10%玉米淀粉)和2个精氨酸添加水平(0%和1%)。结果表明:高能组可显著降低猪的平均日采食量(P0.05)。饲粮能量和精氨酸水平对猪的胴体性状无显著影响(P>0.05)。高能组可极显著提高猪背最长肌剪切力(P0.05);在高能组饲粮中添加精氨酸可提高背最长肌肌内脂肪含量(P>0.05),极显著降低肌肉剪切力(P0.05);饲粮能量和精氨酸水平对肌肉剪切力的影响有交互作用趋势(P=0.061)。由此可见,育肥后期饲粮添加椰子油可提高消化能浓度,能显著改善饲料利用率,但不利于猪肌内脂肪的沉积,提高了肌肉剪切力,而在高能量饲粮中添加精氨酸则有助于提高肌内脂肪含量,降低剪切力,改善肉质。

为了探讨羟乙基纤维素增稠剂添加量对达克罗涂层耐腐蚀性能的影响规律及机理,分别采用快速腐蚀试验和电化学阻抗谱(EIS)技术对不同增稠剂添加量涂层的耐蚀性和腐蚀过程进行了研究。结果表明:随着增稠剂添加量的增加,达克罗涂层中铝锌粉分布密度提高;涂层表面铝锌粉与腐蚀介质容易反应生成腐蚀产物覆盖涂层表面,从而阻止了腐蚀的进一步进行,提高了涂层的防护性能。

旨在考察自主研制的功能性复合添加剂添加到饮水中对断奶仔猪生长性能、养分消化率和血液指标的影响。试验选取32头初始体重为(7.08±0.47)kg的21日龄断奶健康的"杜×长×大"三元杂交仔猪,按体重相近的原则,随机分为2个处理,每个处理16个重复,饲喂相同的饲粮,分别给予普通的水(对照组)和添加了功能性复合添加剂的水(添加剂组),添加剂与饮水比例为1g∶4L。试验期14d。结果表明:1)饮水中添加功能性复合添加剂显著降低仔猪第8~14天的料重比(P<0.05),有降低仔猪第1~14天料重比的趋势(P=0.07);2)饮水中添加功能性复合添加剂显著提高仔猪对饲粮中粗蛋白质、粗灰分和钙的消化率(P<0.05);3)饮水中添加功能性复合添加剂显著降低了仔猪血清中尿素氮、甘油三酯、白介素-6和白介素-1的含量(P<0.05)。综上表明,饮水中添加功能性复合添加剂有提高断奶仔猪生长性能的趋势,这可能与其改善仔猪营养物质的消化利用和仔猪免疫状态有关。
