During the peak summer months in southern China, South American white shrimp farming enters a critical phase. Water temperatures continue to rise, dissolved oxygen levels fluctuate dramatically, algae levels fluctuate, and pathogens proliferate. These intertwined pressures can easily lead to shrimp stress, decreased feeding, and even mass mortality. High temperatures are not only an environmental challenge but also a severe test for the shrimp's physiological functions. During this period, scientific and rational nutritional management becomes crucial for maintaining shrimp health. A high-quality South American white shrimp compound premix feed, through precise nutritional intervention, builds an internal defense system for shrimp during the hot season, helping them maintain a stable survival rate and safely navigate this "high-risk period."The key to achieving stable survival lies in enhancing the shrimp's stress resistance. High temperatures accelerate shrimp metabolism, leading to a sharp increase in energy consumption. This, combined with the accelerated accumulation of free radicals in the body, increases the risk of cellular oxidative damage. Compound premixes are rich in antioxidants, such as vitamin C, vitamin E, and selenium. These antioxidants work synergistically to scavenge excess free radicals in the body and mitigate heat stress damage to the hepatopancreas and intestinal tissues. The hepatopancreas, the metabolic and detoxification center of shrimp, is easily damaged by high temperatures. These nutrients help maintain its structural integrity and stable function, enhancing overall resilience.Intestinal health is another vital defense. High temperatures often disrupt shrimp's digestive enzyme activity, leading to reduced feed utilization and increased residual feed, which in turn pollutes water quality. Prebiotics and functional polysaccharides added to premixes promote the growth of beneficial intestinal bacteria, inhibit the overgrowth of harmful bacteria, and maintain a balanced intestinal microbiome. A healthy intestine not only improves nutrient absorption but also strengthens the immune system, reducing deaths from enteritis. Some formulas also contain natural plant extracts that protect the liver and stomach, helping shrimp maintain a strong appetite in high temperatures and preventing weakness caused by anorexia.Strengthening the immune system is also crucial. High temperatures weaken shrimp's nonspecific immunity, making them more susceptible to common pathogens like Vibrio. Compound premixes, through a strategically formulated blend of immune-enhancing factors like β-glucan and yeast cell wall extract, activate the shrimp's phagocytes and phenoloxidase system, enhancing their ability to recognize and resist foreign pathogens. This "endogenous defense" doesn't rely on antibiotics, but rather mobilizes the shrimp's own potential to establish long-lasting immune memory, giving the shrimp a greater survival advantage in complex environments.In addition, the mineral and electrolyte balance in the premix also plays a regulatory role. Increased gill excretion in shrimp at high temperatures can lead to a loss of key ions like potassium and magnesium, impairing nerve conduction and muscle contraction. Appropriate trace element supplementation helps maintain stable osmotic pressure and prevent convulsions or sinking to the bottom due to electrolyte imbalances. Furthermore, certain micronutrients participate in hemocyanin synthesis, indirectly improving oxygen-carrying capacity and enhancing tolerance during periods of low dissolved oxygen.Feed palatability is particularly important during high temperatures. As water temperatures rise, shrimp's sense of smell and taste may decrease. If bait lacks appeal, they may not eat enough. High-quality premixes often contain natural attractants, such as squid viscera powder and shrimp paste extract. These release strong feeding signals, stimulating shrimp to actively forage, ensuring a continuous supply of nutrients and preventing hunger-induced decline in health.Ultimately, the value of South American White Shrimp Compound Premix feed lies not only in "feeding" but also in "strengthening." It's more than a simple nutritional supplement; it's a comprehensive solution that combines stress relief, liver and intestine protection, immune support, and metabolic stability. In the unbearable heat of ponds, it instills resilience in shrimp, enabling each shrimp to face environmental challenges with greater resilience. As night falls, the shrimp still active on the surface are the truest echo of this silent protection.
