White needle-like crystals or crystalline powderPackage:
25KG/DrumDescription
The compound nicotinamide exists as white needle-like crystals or a crystalline powder, devoid of odor or with a slight unpleasant smell, and possesses a mildly bitter taste. It has a relative density of 1.4 and melts at temperatures ranging from 129 to 131 °C. Solubility tests reveal that 1 gram of this substance can dissolve in 1 milliliter of water, 1.5 milliliters of ethanol, or 10 milliliters of glycerol; however, it remains insoluble in ether. In an aqueous solution with a concentration of 10%, the pH ranges between 6.5 and 7.5. Additionally, it exhibits weak hygroscopic properties and demonstrates remarkable stability under dry air conditions even when exposed to light, heat, acids, alkalis or high temperatures; nevertheless heating it in alkaline or acidic solutions results in the formation of nicotinic acid.

Application
As a feed additive, nicotinamide enhances the livestock and poultry's ability to resist and prevent diseases, while promoting their growth. It is the simplest structured vitamin with the most stable physicochemical properties, making it an indispensable nutrient for animals. Nicotinamide combines with ribose, phosphoric acid, and adenosine to form nicotinamide adenine dinucleotide (coenzyme I) and nicotinamide adenine dinucleotide phosphate (coenzyme II), which participate in various cellular respiration processes as well as important energy metabolism processes. They play a crucial role in the utilization of energy, synthesis and decomposition of fats, proteins, and carbohydrates in animals' bodies. Insufficient intake of nicotinamide leads to inadequate coenzyme synthesis, affecting the absorption of carbohydrates, fats, proteins, and energy supply resulting in severe metabolic disorders. Adding an appropriate amount of nicotinamide to animal feed is highly beneficial for satisfying their growth and development needs while improving yield. The addition of niacinamide to animal feed can enhance protein utilization rate as well as increase milk production quantity and improve meat quality for dairy cows as well as fish such as chicken duck cattle sheep.

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.
