TNF-α和FAS在6个地方猪种血液中的含量与肉质性状的关系研究

The Study on the Relationship of Content of TNF-α and FAS in Blood of 6 Pig Breeds and their Meat Quality Traits

为了研究肿瘤坏死因子-α(TNF-α)和脂肪酸合成酶(FAS)在血液中的含量与肉质风味表型指标的相关性,试验采用酶联免疫吸附试验(ELISA)技术检测了6个地方猪种血液中TNF-α和FAS的含量。结果表明:血液中的TNF-α含量成华猪最高(183 pg/mL),内江猪最低(138.97 pg/mL);血液中的FAS含量丫杈猪最高(8.47 ng/mL),雅南猪最低(6.43 ng/mL)。相关性分析显示,TNF-α和FAS在血液中的含量与肌内脂肪含量和肌纤维直径呈负相关,与瘦肉率呈正相关。表明TNF-α和FAS对猪肉品质具有负调控作用,而对猪胴体品质具有正调控作用。

In order to investigate the correlation of TNF-α and FAS content in blood with meat flavor phenotype index, the contents of TNF-α and FAS were measured in blood of 6 pig breeds with enzyme-linked immunosorbent assay(ELISA). The results showed that the content of TNF-α in the Chenhua pig blood was the highest among the 6 pig breeds(183 pg/mL), which was the lowest in Neijiang pig blood among the 6 pig breeds(138.97 pg/mL);the content of FAS in the Yacha pig blood was the highest among the 6 pig breeds(8.47 ng/mL), which was the lowest in Yanan pig blood among the 6 pig breeds(6.43 ng/mL). Correlation analysis showed that the contents of TNF-α and FAS in blood were negatively correlated with intramuscular fat content and muscle fiber diameter, and positively correlated with lean meat rate. These results indicated that TNF-α and FAS had negatively regulation effect on pork quality.
