USES OF PREPARED PROBIOTICS AS GROWTH PROMOTER IN CATTLE PRODUCTION TO AVOID ADVERSE EFFECT ON HEALTH

Abstract

The present study was conducted to evaluate the effect of probiotics as supplemented feed additives in cattle production. A total of 9 cross bred bull calves (three for each treatment) were assigned to the three experimental dietary treatments. Experimental groups consisted of control T 1 probiotics), T 2 (fed probiotic containing bacteria culture) and T 3 (basal diet with no which were fed probiotics with bacteria and yeast both culture throughout the experimental period. Compared to control, inclusion of probiotic increased (P<0.05) total live weight gain. Significantly (P<0.05) lowest glucose level found was in probiotic group which indicates better fiber digestion and better weight gain. Significant difference (P<0.05) was found in LDL concentration and triglyceride among the trial group. Probiotic groups had lower LDL concentration and triglyceride than the control one. In addition, inclusion of probiotic resulted significant (P<0.05) increases in haematological parameters like haemoglobin, white blood cell and Erythrocyte proportion as well as PCV and MCV. However, Probiotics had no effect on serum cholesterol and HDL levels. Results indicate that partial substitution of probiotics improve growth performance by improving fiber digestion and modulating immune status of cattle.
