What is the appropriate amount of salt to add? Asking everyone for advice
Asking for advice on the amount of salt to add
Hello everyone, I am in the 4% premix business. The book says the optimal salt addition rate for lactating sows is 0.4%-0.5%. But we add 0.12% anhydrous sodium sulfate and some rice hull bran to the sow feed to prevent sow constipation. Also, the premix contains some 98% lysine. I think anhydrous sodium sulfate and lysine hydrochloride both contain salt components, so I only added 0.3% salt to the sow feed (calculated on a complete feed basis). I do not know whether this is acceptable. For preventing sow constipation, is adding 0.12% anhydrous sodium sulfate appropriate? Please give me some guidance, fellow professionals~~ Thank you in advance~~
---------------------
As far as the amount of salt added is concerned, the main consideration is the amount of sodium ions added.
---------------------
Adding it to 0.4% is no problem
---------------------
To prevent sow constipation, you do not necessarily need to add anhydrous sodium sulfate; adding 2-4% wheat bran is enough. The amount of salt mainly considers the electrolyte balance. Lysine (hydrochloride) generally does not need to be a main consideration. You can consider the amount of fishmeal added, as fishmeal contains high salt. 0.3-0.4% salt will not affect sows.
---------------------
In winter, even if wheat bran is added to 15%, constipation can still occur. Adding anhydrous sodium sulfate to 0.3% is also no problem. In addition, magnesium sulfate can also be considered.

What is the effect of adding anhydrous sodium sulfate to meat duck feed?

Passing by, learning.
---------------------
It depends on your own actual situation. Theoretically it works.
---------------------
Good information, very useful!!
---------------------
A little more or a little less does not matter much. As long as sodium, chloride and potassium ions are roughly balanced, it is fine. Salt is also a feeding attractant.

"Sodium sulfate is commonly known as Glauber's salt, mirabilite, etc. It is white transparent crystalline granules or crystalline powder, containing about 20% sulfur. Sulfur is one of the mineral elements necessary for animals. The animal body contains about 15% sulfur. Sulfur in poultry is mainly present in organic form in sulfur-containing amino acids such as methionine and cystine. Poultry synthesize body proteins, feathers and other body tissues from sulfur-containing amino acids. Analysis has shown that poultry feathers, eggs, chicken meat and other products all contain relatively large amounts of sulfur. Therefore, chickens have a relatively high sulfur requirement. If the sulfur content in the feed is insufficient, especially if sulfur-containing amino acids are insufficient, chicken production performance can be reduced, and the flock is also prone to pecking. Sulfur is necessary for poultry but cannot be synthesized by 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 some people have found that chickens cannot use inorganic sulfur to synthesize methionine, after inorganic sulfur is added to the feed, chickens at least no longer draw on sulfur from sulfur-containing amino acids, thus saving part of the sulfur-containing amino acids; at the same time, it can also provide sodium. Sodium sulfate has different functions depending on the amount added. As a protein nutrition enhancer, the amount added is generally small, mostly controlled within 1%. When it exceeds 1% and reaches about 3%, because ions in the sodium sulfate aqueous solution are not easily absorbed from the intestinal wall, a large amount of water is retained in the intestine after consumption, reflexively causing enhanced intestinal peristalsis, accelerating the discharge of intestinal contents, and achieving a purgative effect, which can treat constipation and food accumulation. Therefore, in practice sodium sulfate is often used as a mild laxative for sows after farrowing."
This is information I once collected online. As for the addition amount of sodium sulfate, 1% or 1%-3%, I always feel it is too much? It is impossible to add this much in practice, right?

0.4% is no problem, you do not need to think too much about it.
