杜皖系杂交野猪的胴体、肉质性状及肉品营养成分分析

The Analyses of Carcass Characteristics, Meat Traits and Meaty Nourishment Composition of Duroc-Anhui Crossbred Wild Boar

选用皖南野猪、杜皖二元猪、杜皖系杂交野猪为亲本,设置3个杂交组合,分析比较3组试验猪后代(BH、B2H、B3H2)的胴体、肉质性状,并对B3H2的肉品进行营养成分分析。结果表明:B2H的瘦肉率、眼肌面积、肉色评分、滴水损失率最优,依次为69.64%、33.87 cm2、3.02、2.43%;BH的屠宰率、大理石纹评分最高,依次为72.19%、2.78;B3H2的pH24 h最高,为5.63;B3H2肉蛋白质,维生素A、E以及12种氨基酸(包含7种必需氨基酸)含量均显著高于家猪肉(p <0.05);矿物质元素Fe、Zn、Mg、Ca以及饱和脂肪酸含量较家猪肉丰富。

The test designed three cross combinations by taking wild boar in southern Anhui, Duroc-Anhui binary hybrid pig, Duroc-Anhui crossbred wild boar as parents. The analyses of carcass characte-ristics and meat traits of offspring (BH, B2H, B3H2) from three kinds of cross combinations were conducted. Additionally, B3H2 was selected and its meaty nourishment composition was analyzed. The results showed that the lean percentage 69.64%, loin eye area 33.87cm2, meat color score 3.02 and drip loss rate 2.43% of B2H were optimal;the slaughter rate 72.19% and marbling score 2.78 of BH were higher than those of B2H and B3H2;the pH24 h of B3H2 was 5.63, which was significant;the contents of protein, vitamins A and E, and twelve kinds of amino acids (including seven kinds of essential amino acids) in the lean of B3H2 were clearly higher (p 3H2 were richer than those in the lean of domestic pig.
