--------------------------------------
I don't understand duck feed, but I've seen some pig farmers use a large amount of rice bran with reportedly good results
--------------------------------------
Calcium is on the low side, and there's a bit too much dicalcium phosphate. Why not use phytase? Such a mature technology would be great for reducing costs! It could also improve environmental benefits
--------------------------------------
The person above is right. Calcium is intentionally limited low, because of concern that the magnesium content of the limestone powder used is slightly high. When calcium is high, there is soft droppings. Now I've switched to a different limestone powder supplier and am preparing to increase calcium. The main reason phytase isn't used is concern about enzyme activity during high-temperature feed processing
--------------------------------------
The original poster has been lurking for many days and has finally surfaced. Isn't this a low-grade formula?
--------------------------------------
The cost is too high. Phosphorus and calcium could be reduced a bit. I just don't know how the egg production rate is with this feed?
--------------------------------------
Oh, this is mid-grade. There's also a high one and a low one
--------------------------------------
Learned something, learned something. Not bad.
--------------------------------------
How much is the feed intake? What's the egg production rate?
--------------------------------------
Does the 0.16% laying duck premix contain wheat enzyme? What are the main nutritional parameters of the rice protein powder?
--------------------------------------
Lacking animal protein
--------------------------------------
The quality of the limestone powder isn't very good. Why not use some shell powder!
