Beyond its widespread use in human food and beverages, L-Tartaric Acid (CAS 87-69-4) is emerging as a valuable additive in animal nutrition, particularly in aquaculture. Research indicates that this organic acid can significantly contribute to the growth performance, nutritional utilization, and immune response of farmed aquatic species, notably Pacific white shrimp (Litopenaeus vannamei).

Organic acids (OAs) like Tartaric Acid are known for their antimicrobial properties. By lowering the pH in the gut, they can modulate the intestinal microflora, inhibiting the growth of opportunistic pathogens such as Vibrio species, which are common causes of disease in shrimp farming. This acidification process not only protects the animal but also creates a more favorable environment for beneficial bacteria, such as lactic acid bacteria (LAB), which are known to improve nutrient digestion and absorption.

Studies have demonstrated that dietary supplementation with Tartaric Acid at specific concentrations can lead to improved growth indices in shrimp, including increased weight gain (WG), final weight (FW), and specific growth rate (SGR). Furthermore, it can enhance the feed conversion ratio (FCR) and protein efficiency ratio (PER), indicating better utilization of feed and improved nutrient assimilation. These improvements are linked to increased digestive enzyme activities and better nutrient digestibility, facilitated by the acidic environment created by Tartaric Acid.

The immune system of shrimp relies heavily on innate immune responses. Research suggests that dietary Tartaric Acid can act as an immunopotentiator, boosting key immune parameters. For instance, it has been shown to increase hemocyte counts, which are critical cells involved in the immune defense of invertebrates. Additionally, it can improve the antioxidant status of the shrimp, bolstering their defense against both biological and non-biological stressors.

A significant benefit observed in studies is enhanced disease resistance. Shrimp fed diets supplemented with Tartaric Acid have shown a markedly lower mortality rate when challenged with pathogens like Vibrio parahaemolyticus, a common threat in aquaculture. This improved survival rate underscores the potential of Tartaric Acid as a tool for promoting animal health and reducing losses in farmed populations.

For aquaculture producers and feed manufacturers, incorporating high-quality L-Tartaric Acid into feed formulations presents a promising strategy for enhancing the productivity and health of farmed shrimp. As a trusted supplier of Tartaric Acid, we support the advancement of sustainable aquaculture practices by providing a key ingredient that contributes to healthier aquatic environments and improved yields.
