Creatine content in the muscle may delay postmortem lactate formation and postpone the pH decline, hence potentially improving the water-holding capacity (WHC) as shown in a previous study including purebred Duroc pigs, although the same study did not find any effect on meat from purebred Landrace pigs. In the present study Danish D(LY) crossbreeds were supplemented with 0 or 50g creatine monohydrate (CMH)/d for five days prior to the slaughter. CMH supplementation had no effect on meat quality indicators (pH and temperature), meat quality attributes (WHC and colour) or eating quality (juiciness and tenderness) of meat from the D(LY) crossbred pigs. As a consequence the D(LY) crossbreed was classified as a non-responder to CMH supplementation.
肌肉中的肌酸含量可能会延迟死后乳酸的形成并延缓pH值下降,因此有可能提高持水能力(WHC),正如之前一项涉及纯种杜洛克猪的研究所表明的那样,尽管同一项研究未发现对纯种长白猪的肉有任何影响。在本研究中,丹麦D(LY)杂交猪在屠宰前5天每天补充0或50克一水肌酸(CMH)。补充CMH对D(LY)杂交猪肉的肉质指标(pH值和温度)、肉质特性(WHC和颜色)或食用品质(多汁性和嫩度)没有影响。因此,D(LY)杂交猪被归类为对补充CMH无反应的品种。
