Abstract:

The purpose of this study is to investigate the differences of slaughter performance and muscle quality and composition between ‘wod’ series broilers (which are self-bred in China) and AA broilers. The slaughter performance, chest muscle quality, flavor precursors content, mineral elements content and vitamins content of 7-week-old broilers were determined, and the differences were compared between ‘wod’ series broilers and AA broilers. The results showed that the dressed percentage, percentage of eviscerated yield and percentage of chest muscle of wod168 and wod178 were extremely significantly lower than those of wod188 and AA (P<0.01), while the percentage of wings was extremely significantly higher than that of wod188 and AA (P<0.01). The pH value and tenderness of chest muscle of wod168 were extremely significantly lower than those of AA (P<0.01), and the L value and b value of meat color were significantly higher than those of AA (P<0.05). The contents of amino acids, mineral elements and crude protein in chest muscle were the highest and the contents of intramuscular fat and cholesterol were the lowest in wod168. wod168 did not have good meat production performance, but performed better on breast meat quality, which was more consistent with consumer demand for good meat quality.
