Abstract

Probiotics are rich sources of viable microorganisms (bacteria or yeasts) and these have a beneficial effect on host health after ingestion. This trial was conducted to assess the effects of growth performance of broilers fed on diets containing different growth promoters. A total of 200 male chicks was allotted into four dietary treatments in which they were fed none, antibiotic (Virginiamycin), probiotic (Lactobacillus plantarum K KKP 529/p, 1.0×106 (cfu/g) or Thymus vulgaris. The growth performances and Lymphocyte cells were the highest in probiotic and Thymus vulgaris (p<0.05) compared with control. The probiotic and herbal plant caused significant decrease (p<0.05) of hetrophile and reduced of H/L Ratio (P<0.05). The Eschertia coli and total bacteria count were lowered with growth promoters when compared to control (p<0.05). These findings confirm the valuable impact of growth promoters on growth performance, haematogical characteristics and on reducing intestinal bacteriology.
