Evaluation of different levels Apple cider vinegar effect on hemolymph parameters and intestinal Vibrio spp. of Litopenaeus vannamei

The objective of this study was to evaluate the effect of dietary supplementation with apple cider vinegar on the hemolymph parameters and Vibrio spp. colony forming unit (CFU) in the intestine of the Litopenaeus vannamei. In this study, two hundred twenty-five L. vannamei with an average initial weight of 10.2±0.04g were fed diets supplemented with of apple cider vinegar for 60 days. Treatments included levels of 0% (control), 2% and 4% apple cider vinegar diets (triplicate). The shrimps were randomly sampled for determination biochemical parameters hemolymph and Vibrio spp. counts at the end of the experiment. The results indicated that Vibrio spp. CFU counts of the shrimp fed with apple cider vinegar diets were significantly lower compared to the control group (P0.05). In contrast, the cholesterol and triglyceride concentrations were significantly decreased in the shrimps fed with diets containing apple cider vinegar and a dramatic decrease was observed in 4% apple cider vinegar treatment (P
