The addition of  STRESSOUT as water-soluble vitamins A, D3, E, and C in poultry nutrition plays a crucial role in promoting optimal health, growth, and productivity. Vitamin A is essential for maintaining good vision, immune function, and skin health in poultry. Vitamin D3 is vital for calcium absorption, bone health, and eggshell quality, making it indispensable in laying hens. Vitamin E acts as a powerful antioxidant, protecting cells from oxidative stress and supporting immune function, while also enhancing the quality of meat and eggs. Vitamin C,  help to reduce stress, improve immune response, and enhance resistance to diseases, especially during periods of high stress like transportation or extreme temperatures. Together, these vitamins contribute to improved overall health, enhanced growth rates, better feed conversion ratios, and higher quality poultry products. Incorporating these vitamins in water-soluble form ensures they are readily available for absorption, particularly during times when feed intake may be reduced, thus supporting the birds' nutritional needs effectively.
