By examining the impacts of taking care of Variety Microscopic organisms FK-23 readiness to Nepal Dark steers in the late swelling period, this paper talks about the expanded worth of hamburger and the attainability. Technique: 10 meat cows were gathered into the Experimental Group and the Benchmark Group, 5 hamburger dairy cattle in the Experimental Group were taken care of E. Microscopic organisms FK-23 planning at 8.0 g each day per head. The trial included weight measure, blood test for White Platelet (WBC), Vitamin A (VA), Vitamin E (VE), Complete Cholesterol (TC), glutei oxaloacetic transaminase (GOT), blood urea nitrogen (BUN) and blood glucose (GLU), and HPLC test for unsaturated fat structure in impartial fat. Results: Contrasting with the Benchmark Group, the Experimental Group had exorbitant craving, apparent increment of everyday addition (DG) (p<0.05), calculable increment of serum VE and TC (p<0.05), about a similar degree of VA, and clear propensity of expanded unsaturated fat in unbiased fat, and showed an end weight increment of 4.3% and corpse weight increment of 9.3 kg. End: Taking care of E. Microscopic organisms FK-23 arrangement to Nepale Dark dairy cattle in the late swelling period enhances the hamburger cows and works on its efficiency.
