Analysis of slaughter performance and meat quality of"Mengxiang series"three-way pigs(Duroc×Landrace×Large)
In order to study the slaughtering performance and meat quality characteristics of Jiayu company's"Mengxiang series"three-way pigs(Duroc×Landrace×Large),slaughter determination and meat quality de-tection were carried out.30 ternary pigs(Duroc×Landrace×Large)with body weight of about 115 kg were se-lected under the same feeding environment and management conditions for slaughter determination,analysed slaughter performance,carcass character and meat colour quality.The results show that:Carcass index analysis showed that the average carcass weight was 85.25 kg,the slaughter rate was 70.25%,the carcass length was 97.45 cm,the backfat thickness was 23.59 mm,the skin thickness was 2.66 mm,and the eye muscle area was 49.31 cm2.Leg-hip ratio was 33.19%.Meat quality index analysis showed that muscle color value was L24 42.93±2.25,pH1 value was 6.37,pH24 value was 5.76,48 h drip loss was 2.53%,hydraulic was 92.58%.This experiment provides reference data support for further improving the carcass quality and quality selection and breeding program of ternary pigs.
