The effect of different slaughter weights on slaughter performance and carcass quality of ternary hybrid pigs
The experiment aims to discuss the effects of different slaughter weights on the slaughter performance and carcass quality of ternary hybrid pigs(Duroc×Landrace×Large white).Select castrated male pigs from the same feeding environment and divide them into 4 groups based on slaughter weight of 110 kg(G1 group),125 kg(G2 group),140 kg(G3 group),and 150 kg(G4 group),totaling 16 pigs.The results showed that:1)Slaughtering performance:The straight length,diagonal length of carcass,and head weight of the G4 group were significantly higher than those of the G1 group(P<0.05);The backfat thickness of G3 group was significantly higher than that of G1 group and G4 group(P<0.05);The plate oil weight of G3 and G4 groups was significantly higher than that of G1 and G2(P<0.05);There was no significant impact on other indicators(P>0.05).2)Carcass quality:The G3 group had significantly higher meat color scores(German,American)and marble texture scores than the other three groups(P<0.05);The drip loss of G4 group was significantly higher than that of G1 group(P<0.05);The tenderness of G2 group was significantly higher than that of G4 group(P<0.05).Overall,there are significant differences in slaughter indicators and carcass quality among ternary hybrid pigs with slaughter weights ranging from 110 to 150 kg.A slaughter weight of 140-150 kg has a positive impact on meat color,texture,and appearance,but 150 kg in-creases drip loss;125 kg may perform better in terms of tenderness.The appropriate slaughter weight is 125-140 kg.
