Is black pig manure better or yellow? An analysis of the reasons
Is black pig manure better, or yellow, and what makes it better?
What is the normal color of pig manure? Why do farmers care so much about manure color?
--------------------------------------
Normally it is yellow; after high copper it is black
--------------------------------------
The odor also needs attention, right? Reduce ammonia nitrogen emissions to protect the environment
--------------------------------------
Do you even need to ask? Of course yellow is better. Black is because in some years people added high copper to promote growth, which made the manure black; this is a drawback. Now they are all foreign pig breeds, and deworming and nutrition are done very well, so the growth-promoting effect of high copper is no longer very effective, but the mistaken idea that black manure promotes growth has taken deep root in people's minds. Actually it is very bad.
--------------------------------------
Yellow is obviously normal. But many pig farm owners like their pigs to pass black manure.
--------------------------------------
Normal pig manure is brown, right? It depends on the type of feed. If alfalfa meal is added, it is grass-brown.
--------------------------------------
With a general corn-soybean meal diet, yellow manure is normal. Some people think black means good digestion; that is complete nonsense, it is merely caused by the sulfate radical in copper sulfate. Farmers are not experts, but unfortunately many of our so-called experts also keep fooling people all day long
--------------------------------------
Support~~~~~~~~~~~
--------------------------------------
Now that Announcement No. 1224 of the Ministry of Agriculture has been implemented, anyone still using high copper had better watch out ----- inspection and fines.
--------------------------------------
The idea that manure must be black to show good digestion is mostly "experts" misleading farmers.
--------------------------------------
If pigs pass less manure, digestion is naturally good.
--------------------------------------
The past teaching said it should be black; now to teach people back it also has to be done slowly. Our industry should strive in the direction of human health, rather than pursuing superficial appearances.
