摘要:

对青海牦牛肉食用品质和血液指标进行较为全面的测定分析。结果表明:牦牛肉色及熟肉率显著高于黄牛肉(P<0.05)。血清指标中谷草转氨酶(GOT)、乳酸脱氢酶(LDH)、高密度脂蛋白(HDL)、尿素氮(Urea)及钾离子和钙离子含量均显著高于对照组(P<0.05),碱性磷酸酶(AKP)活性显著低于对照组(P<0.05)。相关性分析中AKP活性与宰后1h所测得的pH值(pH1),LDH活性与大理石纹,HDL含量与熟肉率,GOT、Urea和肌酐(Crea)含量与宰后24h所测得的pH值(pH24),Mg2+与失水率均呈显著负相关,LDH活性与熟肉率呈显著正相关。

Abstract:

The study was designed to evaluate meat quality traits and determine serum biochemical indices of Qinghai
yak using a NSA-400 type automatic biochemical analyzer. The results show that a significant increase in meat color and
cooking yield was found for yak meat in comparison with the meat of the local yellow cattle (P < 0.05). Moreover, serum
GOT and LDH activities as well as urea nitrogen, K+ and Ca2+ contents of yak were also significantly higher than those of
yellow cattle (P < 0.05). The correlations between AKP activity and pH at 1 h postmortem (pH1), between LDH activity
and marble score, between HDL content and cooking yield, between serum GOT activity, urea nitrogen level or creatinine
level and pH at 24 h postmortem (pH24), and between Mg2+ content and water loss rate were significantly negative, whereas a
significantly positive correlation was observed between LDH activity and cooking yield.

Key words: yak, meat quality, serum, biochemical indices
