【摘要】 以长白山野猪与山东省优良地方品种莱芜猪的杂交1代猪(简称野莱Fl代猪)和长×大白猪(各18头,公母各半)为研究对象,采用舍饲+放牧的方式,利用不含任何添加剂的绿色玉米、豆粕、麦麸组成的日粮,在同样条件下饲养至90kg左右时,按照标准方法进行屠宰,对试验猪的常规肉质性状、脂肪酸组成、肌肉组织学性状、氨基酸和肌苷酸含量进行了系统全面的测定研究。结果表明:野莱F1代猪肉的肉色、大理石纹、失水率、滴水损失、熟肉率、剪切值和肌内脂肪含量均显著(P<0.05)或极显著好于长×大白猪(P<0.01);F1代猪肉的饱和脂肪酸极显著低于长×大白猪(P<0.01),而多不饱和脂肪酸尤其是亚油酸、亚麻酸、花生四烯酸等人体必需脂肪酸却极显著高于长×大白猪(P<0.01),多不饱和脂肪酸和饱和脂肪酸之比为1:2.20;F1代猪的肌纤维比长×大白猪细,肌小节比长×大白猪长(P<0.01);除脯氨酸外,F1代猪的其他17种氨基酸含量、氨基酸总量、必需+半必需氨基酸含量,鲜味氨基酸和肌苷酸含量,均显著或极显著高于长×大白猪(P<0.05或P<0.01)。结果提示:野莱F1代猪肉的肉品品质和营养价值比长×大白猪好,适合作为生产安全优质绿色猪肉的原料猪用。更多还原

【Abstract】 In this research,we put Fl hybrid with boar and Laiwu pigs and white pigs of Landrace and Yorkshire(each 18 heads and male,female in the same evenly) as research object.Fl hybrid with boar and Laiwu pigs were hybridized by Mount Changbai boar with Laiwu pigs which has been the finenes local variety in Shandong Province.We adopted confinedness and grazing breeding way.Ration,without any additive,contained green corn,soybean meal and wheat bran.We breeded the pigs to 90 kg at the same condition,abataged them according to the standard method and researched the pigs’ meat character,fatty acids composition,histology character,Amino acid contents and inosinic acid contents all round.The results indicated:Meat color score,marbling score,water loss,drip loss,cooked-meat ratio,shear force and intramuscular fat contents of Fl hybrid with boar and Laiwu pigs were better than white pigs of Landrace and Yorkshire significantly(P<0.05) or extreme significantly(P<0.01);Satisfied fatty acid and monounsaturated fatty acid of Fl hybrid with boar and Laiwu pigs were lower than white pigs of Landrace and Yorkshire extreme significantly(P<0.01),but the polyunsaturated fatty acid which is the essential fatty acid of people,expecially linoleic acid,linolenic acid and arachidonic acid etc were higher than white pigs of Landrace and Yorkshire extreme significantly(P<0.01),and the proportionality of polyunsaturated fatty acid and satisfied fatty acid was 1:2.20.Sarcomere length of Fl hybrid with boar and Laiwu pigs was longer than white pigs of Landrace and Yorkshire significantly(P<0.01) and muscle fiber diameter was finer significantly(P<0.01);17 kinds of Amino acid contents except proline,Total amount of amine acid,essential amino acid+semi-dispensable amino acid contents,palatable amine acid contents and inosinic acid contents of Fl hybrid pork with Boar and Laiwu pigs were higher than white pigs of Landrace and Yorkshire significantly(P<0.05) or extreme significantly(P<0.01).The results prompted:meat quality and nutritive value of Fl hybrid with boar and Laiwu pigs were better than white pigs of Landrace and Yorkshire,and it can become the raw material pigs for producing safety,fine quality and green pork.更多还原
