Abstract

Abstract Recent research efforts have focused on replacing expensive imported genetically modified soybean meal (GM SBM) as a protein source in animal diets with guar meal characterized by similar nutritional characteristics, which could improve meat quality. The aim of this study was to determine the effect of guar meal protein fed to pigs on carcass quality and the content of major nutrients and fatty acids in the longissimus lumborum (LL) muscle. Pigs were divided into four groups. Control group (1) animals were fed diets containing SBM as the main protein source. In diets for experimental groups 2, 3 and 4, SBM protein was replaced with guar meal protein in 25%, 50% and 75%, respectively. It was found that SBM replacement with guar meal protein at 25% affected carcass weight and the lean content, fat content and protein content of the LL muscle. An analysis of linear correlations revealed a strong negative correlation between the concentrations of monounsaturated fatty acids (MUFAs) and saturated fatty acids (SFAs) in the LL muscle of pigs fed diets containing 25% of guar meal protein, which is nutritionally desirable. The results of this study suggest that the dietary inclusion of guar meal protein at up to 25% of SBM protein has no negative effects on the fattening performance of pigs. Meat quality was not affected by diets fortified with guar meal protein.
日粮添加瓜尔豆粉蛋白对猪胴体品质和化学成分的影响
摘要近年来,研究人员致力于用具有相似营养特性的瓜尔豆粕替代昂贵的进口转基因豆粕作为动物饲粮中的蛋白质来源,以改善肉质。本试验旨在研究饲粮瓜尔豆粕蛋白对猪胴体品质及腰最长肌主要营养物质和脂肪酸含量的影响。猪被分成四组。对照组(1)饲喂以豆粕为主要蛋白质来源的饲粮。在试验2、3、4组饲粮中,分别以25%、50%、75%的瓜尔豆粕蛋白替代豆粕蛋白。结果表明,以25%的瓜尔豆粕蛋白替代SBM,影响了胴体重和LL肌的瘦肉含量、脂肪含量和蛋白质含量。线性相关分析显示,在饲粮中添加25%瓜尔豆粕蛋白的猪的LL肌中,单不饱和脂肪酸(MUFAs)和饱和脂肪酸(sfa)浓度呈强烈的负相关,这是营养上理想的。本研究结果表明,饲粮中添加高达25%的瓜尔粉蛋白对猪的育肥性没有负面影响。加瓜尔粉蛋白的日粮对肉质没有影响。
