Effect of Dietary Chlorella Supplementation on Growth Performance, Immune Response, and Intestinal Micro Flora Concentration of Broiler Chickens

Abstract

A study was conducted to investigate the effect of dietary supplementation of feedstuff of Chlorella (Chlorella vulgaris) to replace of antibiotic in the diets of broiler chickens. A total of 720 1-d-old straight run broiler chicks (Ross × Ross) was randomly assigned into six treatments with four replicate pens (30 birds/replicate pen) for 5-wk. A corn-soy bean meal basal diet was formulated, the treatment groups were negative group (NC, antibiotic-free diet) and 0.1% virginiamycin in as antibiotic growth promoters (PC), 1.0% fresh liquid Chlorella (T1), 1.0% dried Chlorella powder (T2), 1.0% commercial Chlorella product and 1.0% (T3) and commercial Chlorella product 0.5% (T4) were added to the basal diet to form six dietary treatments. No significant differences were found among the treatments for feed intake and feed conversion of broiler chickens during the whole experimental period, but the BW gain was significantly higher (P<0.05) in commercial Chlorella product supplemental groups than the control group (NC and PC groups). Dietary supplementation of Chlorella significantly (P<0.05) increased the plasma IgA, IgM and IgG concentration of chicks compared to NC and PC groups. Supplemental AGPs and commercial chlorella product did not affect the E. coli and Salmonella concentration in the intestinal microflora of broiler chicks; however, the population of Lactobacillus was significantly increased (P<0.05) when birds were fed commercial Chlorella product groups. It is concluded that commercial Chlorella product supplementation could be used as an alternative of antibiotics to promote growth and immune response by increasing the production of lactic acid bacteria in the intestinal microflora of broiler chickens.
