Abstract
This study assesses how dietary supplementation with L. acidophilus affects the growth performance, biochemical parameters, antioxidant status, and digestive enzyme activity of Whiteleg Shrimp (P. vannamei). For 14 weeks, four shrimp groups (20 shrimp/hapa-2m³), each consisting of 240 healthy P. vannamei, were given balanced diets that contained 38% crude protein. They were also given supplements containing tested levels of T1, T2, T3, and T4 (0.00, 200, 400, and 600 mg L. acidophilus/Kg diet), respectively. The FCR and PER of the T2, T3, and T4 groups were significantly lower (best) than those of the control group (worst), while the levels of FBW, WG, ADG, SGR, and RGR were significantly greater in the L. acidophilus groups. When compared to the control group, the antioxidant activity data showed no changes in MDA, TAC, or CAT activities in the group that was fed diets supplemented with L. acidophilus. Compared to the control, the T3 showed a considerable increase in the predicted digestive enzyme activity (lipase and amylase). However, there was no appreciable variation in the protease levels between the control and P. vannamei-treated groups. L. acidophilus has been found to significantly influence the production of HSP70, IL-1β, and IGF-1 when included in the diets of P. vannamei shrimp. In summary, the results of the study show that supplementing with L. acidophilus increases P. vannameigrowth and resistance.
