Effects Of Probiotics (Saccharomyces Cerevisiae) And Phytobiotics (Zingiber Officinale) On Growth Performance Of Labeo Rohita Fish

Abstract

With the intensification and pollution of aquatic environments, fish species have faced various health challenges leading to population declines. To enhance fish meat quality, this study investigates the impact of dietary supplementation with probiotic Saccharomyces cerevisiae, and phytobiotics Zingiber officinale, both individually and in combination, on the growth and serum biochemical parameters of Labeo rohita fingerlings. Over 60 days, fingerlings were provided with four distinct diets: a control diet with no supplements, a diet with 5% yeast, a diet with 5% ginger, and a diet with a combination of 2.5% yeast and 2.5% ginger. The results revealed that the combination of probiotics and phytobiotics (yeast+ginger) significantly improved several key growth performance indicators. These included a notable increase in percentage weight gain, percentage length gain, average daily weight gain, average daily length gain, specific growth rate, total protein levels, and protein efficiency rate compared to the control group (p < 0.05). Additionally, the survival rate remained at 100% for all groups under investigation. Furthermore, the study found that the supplementation with probiotics and phytobiotics led to a significant decrease in the levels of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase compared to the unsupplemented group. This indicates enhanced liver function and overall fish health. These findings emphasize the potential benefits of incorporating probiotics and phytobiotics in the diets of Labeo rohita fingerlings, offering a promising approach to mitigate the impact of intensified aquaculture and pollution on fish populations.
