β—肾上腺素能兴奋剂苯甲醇胺盐对猪肉脂品质的影响

A STUDY OF THE EFFECTS OF β—ADRENERGIC AGONISTS CLENBUTEROL IN PIG MEAT-FAT QUALITY

以人工合成的β—肾上腺素能兴奋剂苯甲醇胺盐(Clenbuterol)为研究为象,用24头内蒙黑猪进行了饲喂和包埋试验。试验分为对照组、试验1组(饲喂10ppm) 试验2组(饲喂20ppm)和试验3组(包埋50毫克/45天·头)。本试验对13项肉脂品质指标进行了分析,结果表明,β—兴奋剂苯甲醇胺盐对肌肉肉色、大理石花纹、滴水损失、肌纤维直径、肌大束间距和脂肪皂化价有降低的作用。同时,它也使肌肉系水力和脂肪碘价、熔点升高,但各项指标各组间差异不显著(P>0.05).

β—adrenergic agonists clenbuterol wastested in additiving and embedding for itseffects of twenty four growing-finishing pigs assigned to four treatment groups.Clenbuterol was administered in the feedat 0 (Control group),10 (treatment Ⅰ)and 20ppm (treatment Ⅱ)and embedded at50mg·head^(-1).45d^(-1)(treatment Ⅲ).Thirteenmeat-fat quality was studied.The resultsshowed that musclecolour,marbling,driploss,fiber diameter,fascicule distanceand saponification number were decreasedreand muscle water binding capacity,fatiodine number and melting point were increased.But these items hadn't differentnotablely between groups (P>0.05).
