Application
β-carotene serves as the precursor of vitamin A, and its conversion efficiency to vitamin A varies significantly across different animal species. Additionally, β-carotene possesses independent physiological effects unrelated to vitamin A, including enhancing intercellular information transfer and acting as an antioxidant that interrupts chain reactions by eliminating toxic oxygen radicals within the animal's body. It also improves the animal's immunity against bacteria and viruses, thereby enhancing survival rates in cultured animals. Furthermore, it promotes animal growth and enhances production performance, particularly in female animals where it has a noticeable impact on poultry reproductive performance. Moreover, β-carotene acts as a coloring agent in feed to stimulate livestock and poultry appetite through altering feed coloration. Lastly, β-carotene exhibits antioxidant properties that enhance the body's immune capabilities by regulating intracellular concentrations of free radicals and hydrogen peroxide generated during normal metabolic processes.

Vitamin B1 , also known as thiamine or thiamine, is an indispensable member among the group of vital B vitamins due to its important involvement in facilitating normal glucose metabolism, while ensuring the proper functioning of nerve conduction pathways along with heart performance and gastrointestinal tract health. In addition, it collaborates with adenosine triphosphate by forming vitamin B1 pyrophosphate (thiamine diphosphate), which serves as an imperative coenzyme necessary for the regulation of carbohydrate metabolism.

Vitamin E 50% is the most used in feed additives, with 50% conventional, water soluble VE content. When vitamin E 50% is deficient, it will lead to infertility, leukodystrophy, nutritional myasthenia, liver necrosis, poor growth, nutritional deficiencies and other diseases in animals, so it is necessary to add vitamin E in feed in time.

Nicotinic acid, also known as vitamin B3, is mainly found in animal organs and muscle tissue and also exists in trace amounts in fruits and egg yolks. It is one of the 13 essential vitamins, belonging to the B vitamins, heat-resistant, and capable of sublimation, and is a water-soluble vitamin. Nicotinic acid can be converted into nicotinamide in the human body, involved in the synthesis of coenzyme I and coenzyme II, the body's lipid metabolism, the oxidation of tissue respiration, and the anaerobic decomposition of sugars have an important role.
