Abstract
The slaughter characteristics and physical properties of longissimus dorsi of Yunnan black goats were studied in this paper.The animals were under barn feeding condition.Six 6-month-old rams and six 12-month-old rams were used in this experiment.Pre-slaughter weight,carcass weight,dressing percentage,eye muscle area,GR value and ratio of meat to bone of 6-month-old rams were 39.92 kg,20.98 kg,54.46％,14.59 cm2,0.86 cm and 3.89,respectively.The corresponding indicators of 12-month-old rams were 54.37 kg,27.80 kg,51.78％,16.79 cm2,1.12 cm and 3.43,respectively.The score of meat color,marbling score,pH 45 min,water loss rate,cooking percentage,drip loss and tenderness of 6-month-old rams were 4,1.5,6.27,5.22％,56.31％,3.71％ and 59.57 N,respectively;the corresponding indicators of 12-month-old rams were 4.6,1.6,6.37,5.41％,54.19％,3.26％ and 60.23 N,respectively.The results showed that Yunnan black goat had good meat production performance.关键词
