Synergetic effects of multispecies probiotic supplementation on certain blood parameters and serum biochemical profile of broiler chickens

Abstract

The present study carried out to evaluate the effects of a multispecies probiotic isolates namely, Lactococcus lactis ssp. Lactis (Lact. lactis) and Lactobacillus plantarum (L. plantarum) on certain hematological parameters, white blood cells (WBCs), red blood cells (RBCs) counts and hemoglobulin (Hb) and serum biochemical contents, lipid profile, total proteins and serum glucose (PG), in broiler chicks. Two hundred and ten 1-day old Hubbard broiler chicks were randomly divided into seven experimental groups and fed a basic diet with 22.4% protein and 3160 kcal/ kg. The experimental groups include control group and six treatment groups that supplemented probiotic in water at final concentration of 109cfu/mL and/or 1012cfu/mL of Lact. lactis and L. plantarum separately or in combination for period of 42 days and tested on scheduled intervals. The hematological analysis revealed a high significant effect (p<0.05) on counts of WBCs, RBCs and Hb concentration in all probiotc-treated groups from age of 14 days with a highly obvious increase at the experiment end (42 day). In addition, probiotic supplemented groups showed the lowest serum cholesterol, triglyceride, and total lipid contents as well as higher contents of blood glucose and total protein compared to the control group. Based on these results, it could be concluded that administration of Lact. Lactis and/or L. plantarum improves the physiological traits of broilers.
