Comparative Effect of Different Levels of Probiotics (Protexin) on Hemato-chemical Profile in Broilers

The intent of the present study was to evaluate the effect of five different levels (0, 25, 50, 75 or 100 gm/ton) of probiotic (Protexin) supplemented in feed (Finisher) on blood profile of broiler chicken. Three hundred seventy five broilers (four weeks old) were randomly divided into 15 replicates having 25 birds in each replicate. These replicates were assigned to five dietary Treatments (0, 25, 50, 75 or 100 gm/ton protexin supplemented in feed) having three replicate in each treatment group. Each diet was offered to three pens of 25 broilers each. At the end of the experiment, blood samples were collected from 15 birds per treatment group. There was no mortality recorded at higher levels of probiotic in both strains. Results revealed that hematological values, serum urea, serum creatinine, serum triglycerides, serum high-density lipoprotein level, serum cholesterol level and serum low-density lipoprotein concentrations among all the groups were not affected (P>0.05) by treatments. However, blood hemoglobin concentration, serum glucose level and serum total protein concentration were increased significantly (P<0.05) in blood of birds feeding finisher ration supplemented with protexin. It was concluded that different levels of protexin in finisher ration of broiler may improve some of the blood parameters.
