Abstract

The purpose of this study was to compare the differences on growth performance, slaughter performance, meat quality and intramuscular fat (IMF) deposition related gene expression between dzo and yak in house feeding. Ten healthy male yak and male dzo (Tibetan cattle×maiwa yak) with similar body weight and age (4 years old) were selected and divided into dzo group and yak group, with 5 heads in each group. Both 2 groups were fed the same diet for a trial period of 153 days. The results showed as follows:1) the average daily gain, carcass weight and longissimus dorsi cooked meat rate, IMF content of dzo group were significantly higher than those of yak group (P<0.05). The longissimus dorsi shear force of dzo group was significantly lower than that of yak group (P<0.05). 2) The activities and gene expression levels of hormone sensitive lipase (HSL) and carnitine transferase-1 (CPT-1) in longissimus dorsi of yak group were significantly higher than those of dzo group (P<0.05). 3) There were no significant differences in initial weight, final weight, average daily feed intake, feed to gain ratio, net meat weight, slaughter rate, net meat rate, and pH1 h, pH24 h, fatty acid synthetase (FAS) and acetyl coenzyme A carboxylase (ACC) activities and genes (sterols regulating element binding protein 1, peroxidase proliferation activated receptor γ, FAS and ACC) relative expression levels in longissimus dorsi between dzo and yak (P>0.05). Therefore, compared with yak, dzo mainly inhibits the gene expression of HSL and CPT-1 to reduce their activities, inhibits fat decomposition, promotes IMF deposition, improves the tenderness and quality of beef.
