Ask about the amount of salt added.

Hello, everyone. My brother makes 4% premix. The book says that the best amount of salt for lactating sows is 0.4% and 0.5%, but we added 0.12% Yuanming powder and some bran to the sow feed to prevent sow constipation. And there is still a part of 98% lysine in the premix. I think both Yuanming powder and lysine hydrochloride contain salt. So I only added 0.3% salt (at full price) to the sow feed. I wonder if this is appropriate to prevent sow constipation by adding 0.12% Yuanming powder? Please give me some advice. thank you first. Only in terms of the amount of salt added, we mainly consider the amount of sodium ion. -it's okay to add 0.4%.-to prevent sows from secreting, you don't have to add Yuanming powder, you can add 2-4% wheat bran. The amount of salt mainly considers the problem of electrolyte balance, lysine (hydrochloride) generally can not be considered as the main consideration, can consider the addition of fish meal, fish meal contains high salt. 0.3-0.4% salt has no effect on sows. -constipation will still occur when wheat bran is added to 15% in winter. Yuanming powder can be added to 0.3%. In addition, magnesium sulfate can also be considered. -what is the function of Yuanming powder added to duck meat? -passing by, studying. -depending on your actual situation, it works in theory.-good information, very useful! -it doesn't matter much if you have more or less. Just keep a rough balance of sodium, chlorine and potassium. Salt or food attractant. -finally, this post was edited by crude protein at 10:00 on 2009-12-18. "Sodium sulfate, commonly known as mirabilite, dermite, etc., is a white transparent crystal particle or crystalline powder, containing about 20% sulfur, which is one of the essential mineral elements for animals. 15% sulfur in animals. Sulfur in poultry mainly exists in organic form in methionine, cystine and other sulfur-containing amino acids. Poultry is composed of sulfur-containing amino acids to synthesize body proteins, feathers and other body tissues. According to the analysis, there are more sulfur in poultry feathers, eggs, chicken and other products. Therefore, chickens need more sulfur, such as insufficient content of sulfur in feed, especially insufficient sulfur-containing amino acids, which can reduce the production performance of chickens, and chickens are also prone to pecking disease. Sulfur is necessary for poultry and cannot be synthesized for poultry, so it must be supplied by feed. Organic sulfur is mainly added in the form of methionine and cystine, but it is expensive, so sulfate can be used to supplement inorganic sulfur. Although it has been found that chickens cannot synthesize methionine from inorganic sulfur, after inorganic sulfur is added to the feed, chickens at least no longer use sulfur in sulfur-containing amino acids, which can save some sulfur-containing amino acids and provide sodium. Sodium sulfate has different functions due to different amount of sodium sulfate. As a protein nutritional fortifier, the addition amount is generally less than 1%, and when more than 1% is about 3%, because the ions in the aqueous sodium sulfate solution are not easily absorbed from the intestinal wall, a large amount of water is retained in the intestine after taking it, which reflexively causes the intestinal peristalsis to strengthen, accelerate the excretion of intestinal contents, achieve the purgative effect, and can treat constipation and food accumulation, so sodium sulfate is often used as a laxative for sows after delivery. " This is the information that has been collected on the Internet. The addition of sodium sulfate is 1% or 1% 3%. Do you think it is too much? It is impossible to add so much in practice, is it? -0.4% is no problem, you don't have to think too much about it.
