Abstract


Objective: By investigating the effects of feeding Enterococcus faecalis FK-23 preparation to Japanese Black cattle in
the late fattening period, this paper discusses the increased value of beef and the feasibility. Method: 10 beef cattle were
grouped into the Test Group and the Control Group, 5 beef cattle in the Test Group were fed E. faecalis FK-23
preparation at 8.0 g per day per head. The experiment included weight measure, blood test for White Blood Cell (WBC),
Vitamin A (VA), Vitamin E (VE), Total Cholesterol (TC), glutamic oxaloacetic transaminase (GOT), blood urea
nitrogen (BUN) and blood glucose (GLU), and HPLC test for fatty acid composition in neutral fat. Results: Comparing
to the Control Group, the Test Group had excessive appetite, appreciable increase of daily gain (DG) (p<0.05),
appreciable increase of serum VE and TC (p<0.05), about the same level of VA, and obvious tendency of increased fatty
acid in neutral fat, and showed an end weight increase of 4.3% and carcass weight increase of 9.3 kg. Conclusion:
Feeding E. faecalis FK-23 preparation to Japanese Black cattle in the late fattening period adds additional value to the
beef cattle and improves its productivity.
