Sodium bicarbonate, also known as acid sodium carbonate, sodium bicarbonate, baking soda, heavy alkali and baking alkali, is an acid salt formed after neutralization of strong alkali and weak acid. It is weakly alkaline when dissolved in water. The molecular formula of sodium bicarbonate is NaHCO ₃. It is an inorganic salt, white crystalline powder, odorless, alkaline and soluble in water. It decomposes slowly in humid air or hot air to produce carbon dioxide, which is heated to 270 ℃ for complete decomposition. In case of acid, it decomposes strongly to produce carbon dioxide.

Adding an appropriate amount of sodium bicarbonate to livestock and poultry feed can effectively improve the digestibility of livestock and poultry feed, improve the laying rate and eggshell strength of laying hens, accelerate the utilization of nutrients and the excretion of harmful substances, and improve the weight gain rate of livestock and poultry; It can keep the resistance and immunity of livestock and poultry in the best state, improve the anti stress ability of livestock and poultry, and play a positive role in preventing livestock and poultry diseases and ensuring their healthy growth.
