Description:
The effect of dietary containing of Bacillus subtilis and Bacillus licheniformis in three groups
including commercial, commercial-indigenous and indigenous was investigated on the
immune parameters (glucose, albumin, total protein, lysozyme, cortisol, immunoglobulin M
(IgM)) and the intestinal flora of white leg shrimp (Litopenaeus vannamei) post larvae. The
shrimp were fed for 60 days with four different diets: control (without probiotics), diet T1
supplemented with 1.5×106 CFU g-1
commercial probiotic, diet T2 with 1.5×106 CFU g-1
commercial-indigenous probiotic, diet T3 with 1.5×106 CFU g-1
indigenous probiotic. At the
end of experimental period, the levels of biochemical parameters (glucose, total protein,
lysozyme, cortisol, IgM) of shrimp fed probiotic diets were significantly higher than in those
shrimps fed the control diet for 60 days. However, albumin concentrations showed no
significant difference between the experimental treatments and the control, but increased by
1.19, 1.15 and 1.14 after 60 days of feeding with diets T1, T2 and T3, respectively. Likewise,
population density of Bacillus bacteria counted in digestive tract of shrimps treated with
probiotic were significantly higher than the control group. Results of this study indicated that
the addition of probiotic bacili can improve immune parameters and modulates intestinal
microbiota of shrimp (L. vannamei) post larvae.
