Talk about the source of calcium in piglet feed

In piglet feed, what is better to supplement calcium? Calcium hydrogen phosphate, calcium dihydrogen phosphate, calcium lactate, which is cost-effective? I remember that when I feed pigs at home, they always add some calcium tablets, which are very cheap-stone powder is undoubtedly the cheapest source of calcium. Stone powder is 100 yuan per ton and contains more than 35% calcium. Calcium hydrogen phosphate contains 21% calcium, 2000 yuan per ton, which is more cost-effective? Stone powder is obviously the most cost-effective, but it is used because of its good absorption of calcium lactate, low acidity and good effect in suckling pig feed. -- bench-v# t; r "p9 w * Y# L6 S!

Calcium hydrogen phosphate pays more attention to the source of phosphorus. -- considering the performance-to-price ratio of raw materials, we should not only consider the raw material itself, but also consider the impact of this raw material on other raw materials and the cost needed to reduce its impact. Therefore, the formula itself is not a simple combination of several raw materials, the consideration of performance-to-price ratio should also put a certain raw material into the formula as a whole to consider its value. Calcium lactate supplement is of course an ideal calcium source, but stone powder is the most economical and cost-effective calcium source. Use calcium formate, the price is not very high, the effect is also very good, many companies are using ah! The inside story of calcium lactate that we learned a few days ago is that stone powder is added with calcium hydrogen phosphate and then lactic acid is added in proportion, so we might as well use stone powder and acidifier, and fermented soybean meal can also be used. -- quoted from the content published by hongshengy888 at 16:03 on 2009-9-19.

But there are more. 6. 10V (^ 8 |: Q% M8? 4T-`2Z & S feels a little more reliable with regular quality, sweat-- right So now I still choose calcium carbonate,-- calcium lactate absorbs well, stone powder economy, adjust according to conditions.
