【摘要】：试验旨在对雉鸡和AA肉鸡肉品质指标和肠道氨基酸转运载体进行比较研究,为探讨二者在肉质评定及中性和碱性氨基酸的吸收利用的差异因素上提供参考。选择饲喂相同试验饲料的18周龄雉鸡和8周龄AA肉鸡各36只,分别随机分为3个重复,每个重复12只,测定并比较肉品质及肠道氨基酸转运载体mRNA表达量。结果表明,雉鸡胸肌和腿肌的肉色值都显著高于AA肉鸡(P0.05);雉鸡胸肌和腿肌的滴水损失率都显著低于AA肉鸡(P0.05);雉鸡胸肌的剪切力极显著高于AA肉鸡(P0.01),腿肌的剪切力显著高于AA肉鸡(P0.05)。雉鸡十二指肠b~(0,+)AT和SAT2的mRNA表达量极显著高于AA肉鸡(P0.01),ATB~(0,+)的mRNA表达量显著高于AA肉鸡(P0.05);雉鸡十二指肠b~(0,+)AT和SAT2的mRNA表达量极显著高于AA肉鸡(P0.01),ATB~(0,+)的mRNA表达量显著高于AA肉鸡(P0.05);雉鸡空回肠CAT2,CAT3,ATB~(0,+)和y~+LAT1的mRNA表达量极显著高于AA肉鸡(P0.01);CAT1,SAT2,y~+LAT2的mRNA表达显著高于AA肉鸡(P0.05),SAT3的mRNA表达量显著低于AA肉鸡(P0.05)。试验说明雉鸡的肉品质指标中肉色和滴水损失率优于AA肉鸡,嫩度差于AA肉鸡;肠道氨基酸转运载体的转运效率高于AA肉鸡。
[Abstract]:The aim of the experiment was to compare the quality indexes of pheasant and AA meat and the carrier of intestinal amino acid transport, and to provide a reference for the difference of meat quality assessment and absorption and utilization of neutral and alkaline amino acids between pheasants and chicken. Thirty-six 18-week-old pheasants and 36 8-week-old AA broilers fed the same diet were randomly divided into 3 repeats with 12 each. The meat quality and the expression of amino acid transport vector mRNA in intestinal tract were measured and compared. The results showed that the meat color value of pectoral muscle and leg muscle of pheasant chicken was significantly higher than that of AA broiler (P0.05), and the water loss rate of pectoral muscle and leg muscle of pheasant chicken was significantly lower than that of AA broiler (P0.05). The shear stress of pectoral muscle of pheasant was significantly higher than that of AA broiler (P0.01), and the shear stress of leg muscle of pheasant was significantly higher than that of AA broiler (P0.05). The mRNA expression of B0, AT and SAT2 in duodenum of pheasants was significantly higher than that of AA (P0.01), and the expression of mRNA in ATB~ (0,) was significantly higher than that of AA (P0.05). The mRNA expression of B0, AT and SAT2 in duodenum of pheasants was significantly higher than that of AA (P0.01), and the expression of mRNA in ATB~ (0,) was significantly higher than that of AA (P0.05). The mRNA expression of CAT2,CAT3,ATB~ (0,) and y ~ LAT1 in the empty ileum of pheasants was significantly higher than that of AA broilers (P0.01). The mRNA expression of CAT1,SAT2,y~ LAT2 was significantly higher than that of AA broilers (P0.05), and the mRNA expression of SAT3 was significantly lower than that of AA broilers (P0.05). The results showed that the meat color and water loss rate of pheasants was better than that of AA broilers, and the tenderness of pheasants was lower than that of AA broilers, and the transport efficiency of intestinal amino acid transport vectors was higher than that of AA broilers.
