普洱茶茶渣对茶花鸡 2 号肉品质的影响.

The aim of this experiment was to investigate the effect of different levels of pu-erh tea residue added to the feeding ration on the meat quality of chahua chicken No. 2. One hundred and fortyfour chahua chicken No. 2 were selected and randomly divided into 3 groups of 6 replicates each, with 8 chickens in each replicate. The control group was fed the basal diet, and the 1% and 2% tea residue groups were added 1% and 2% levels of pu-erh tea residue to the basal diet, respectively. On 28 days, the chicken meat quality was measured at the end of the test. The results showed as follows: ① compared with the control group, there were no significant differences (P>0.05) in the physical characteristics of breast and thigh muscle quality (L* value, a* value, b* value, pH45 min, pH24 h, water loss, cooking loss rate, shear force) and conventional nutrients (crude protein, crude fat and crude ash content) in the 1% and 2% tea residue groups. There was no significant difference in the content of each amino acid in the breast muscle in the 1% tea residue group as well as the content of each amino acid in the thigh muscle in the 2% tea residue group as compared to the control group (P> 0.05). ② Compared with the control group, the Asp, Thr, Ser, Glu, Ala, Cys, Val, Ile, Leu, Tyr, Lys, UAA and TAA contents of the breast muscles of the 2% tea residue groups were highly significantly reduced (P<0.01), Met, Phe, His, Arg, SAA, BAA, EAA and NEAA contents were significantly reduced (P< 0.05), Gly and Pro contents were not significant (P>0.05), and the 1% tea residue groups showed highly significant (P<0.01) decrease in Tyr content of thigh muscle, significant (P<0.05) decrease in Asp, Thr, Ser, Glu, Ala, Val, Ile, Leu, Phe, Lys, Arg, UAA, SAA, BAA, EAA, NEAA, and TAA content, and no Gly, Cys, Met, His, and Pro content significant changes (P>0.05). It can be seen that the addition of 1% and 2% pu-erh tea residue to the ration reduced the amino acid content of the thigh and breast muscles and muscle flavor of chahua chicken No. 2, respectively.
