Abstract
The purpose of this study was to investigate the effects of Clostridium butyricum(CB)on growth performance,serum biochemical indicators,and meat quality in fattening beef cattle.48 healthy Simmental-Hybrid beef cattle were randomly divided into 4 groups(4 replicates×3 cattle)based on body weight(572.63±31.54 kg).The CON group was fed a basal diet,and L-CB,M-CB,H-CB groups were fed experimental diets supplemented with 1×108,5×108,and 1×109 CFU/kg CB,respectively.The pre-trial lasted for 10 days,and the main trial for 120 days.Results:1)Growth performance:The FBW of the H-CB group was significantly higher than that of the CON group(P＜0.05),with no significant difference compared to those of the L-CB and M-CB groups(P＞0.05).The ADG of the H-CB group was significantly higher than that of the CON group(P＜0.05),with no significant difference compared to that of the M-CB group(P＞0.05).The F/G of the H-CB group was significantly lower than that of the CON group(P＜0.05),with no significant difference compared to the M-CB group.2)Serum biochemistry:The levels of TP,INS,and IgG in the M-CB and H-CB groups were significantly higher than those in the CON and L-CB groups(P＜0.05),while the BUN content was significantly lower than that in the CON and L-CB groups(P＜0.05).The TC content in the H-CB group was significantly lower than that in the other groups(P＜0.05),while the GH content was significantly higher than that in the other groups(P＜0.05).The LDL-C content in the L-CB,M-CB,and H-CB groups was significantly reduced(P＜0.05).3)Meat quality:The redness,pH 24 h,and total umami amino acid content in the M-CB and H-CB groups were significantly higher than those in the CON and L-CB groups(P＜0.05).The drip loss and shear force were significantly lower than those in the CON and L-CB groups(P＜0.05).The total sweetness amino acid content in the H-CB group was significantly higher than that in the other groups(P＜0.05).(Conclusion)5×108 and 1×109 CFU/kg CB can effectively improve serum biochemical indicators,meat quality,and promote weight gain in beef cattle.It is recommended to add a dosage of 5×108 CFU/kg.关键词
