Abstract: The aim of this study was to explore the crossbreeding effect of Luxi cattle,so as to promote genetic improvement of Luxi cattle in production performance.111 healthy steers were selected and divided into four groups:Group A included 29 first filial generation (F1) of Limousin cattle×Luxi cattle;Group B included 26 F1 of Simmental cattle×Luxi cattle;Group C included 27 F1 of Japanese Black cattle×Luxi cattle;Group D was the control group including 29 Luxi cattle.Fattening and slaughtering test was in the same feed farm and management condition,and the fattening effects were comprehensively analyzed.The results showed that Limousin cattle,Simmental cattle and Japanese Black cattle could carry out better crossbreeding improvement on Luxi cattle.The Daily weight gain of Simmental cattle×Luxi cattle was significantly higher than that of other groups (P<0.01),and the dressing percentage,carcass weight and slaughter rate of Simmental cattle×Luxi cattle were significantly higher than that of other 3 groups (P<0.05).The marbling score was the best in group C.There was no significant differences of daily mean intake and daily feed cost among four groups (P>0.05).In conclusion,Simmental cattle×Luxi cattle showed the stronger meat production,and Japanese Black cattle×Luxi cattle was the best in marbling.
