Comparative Study on Production Performance and Meat Quality of the Hybrid Offspring of Angus Cattle and Bohai Black Cattle with Bohai Black Cattle
This experiment aimed to improve the production performance of Bohai black cattle.The frozen semen of the imported in-ternational excellent beef breed Black Angus was used to hybridize with Bohai black cattle.The slaughter performance and meat quality of Angus cattle×Bohai black cattle(Angus×Bohai)F1 cattle and Bohai black cattle were observed and compared.The re-sults showed that the body weight of Angus×Bohai F1 cattle at the age of 6 months,18 months,and 24 months was significantly greater than that of Bohai black cattle(P<0.05);The carcass weight and slaughter rate of 24 month old Angus×Bohai F1 cattle were significantly greater than those of Bohai black cattle(P<0.05).The contents of protein,fat,and trace elements iron and zinc content in the Angus×Bohai F1 cattle were significantly greater than those of Bohai black cattle(P<0.05);The eye muscle area,pH value,and water loss rate of Angus×Bohai F1 cattle beef were significantly greater than those of Bohai Black Beef(P<0.05),but there was no significant difference between cooked meat rate and shear force(P>0.05).It can be seen that the crossbreeding of Angus cattle and Bohai black cattle has significant improvement effects,which can improve the carcass weight and slaughter rate of offspring,and also can improve the yield of beef.
