Adding some feed additives to pig feed can promote growth, improve meat quality and prevent disease, thereby increasing pork production, reducing feed consumption and improving farm economic benefits.
However, in production, some farmers do not understand the antagonistic effect between feed additives, often mix them together to feed, which not only fails to achieve the desired additive effect, but has a negative effect. To this end, pigs have summarized some feed additives that can produce antagonistic effects for farmers' reference.
1 water-soluble vitamins and choline
Choline is easily soluble in water and is very alkaline. It can destroy water-soluble vitamins such as vitamin C, vitamin B and pantothenic acid.
2 calcium, phosphorus and choline
　　 Calcium and phosphorus are easily absorbed in an acidic environment, but are rarely absorbed in an alkaline environment. Therefore, choline cannot be added together with calcium powder, calcium hydrogen phosphate or the like.
3 phosphorus and magnesium
Magnesium will reduce the absorption of phosphorus by livestock and poultry. Therefore, when adding phosphorus to livestock and poultry, do not add too much magnesium oxide and magnesium sulfate at the same time.
4 phosphorus and iron
Phosphorus can reduce the absorption of iron by livestock and poultry. Therefore, when adding iron to livestock and poultry, it is not advisable to add too much bone powder and calcium hydrogen phosphate.
5 zinc and calcium
There is an antagonistic effect between zinc and calcium. Therefore, when adding zinc sulfate to the feed, it is not advisable to add too much calcium.
6 calcium, magnesium, iron, aluminum and other trace elements and oxytetracycline
If used at the same time, it will affect the absorption of trace elements in livestock and poultry.
7 vitamin B1 and penicillin
Because the water solubility of vitamin B1 is acidic, it will destroy the efficacy of penicillin.
8 certain vitamins (VB1, VB2, VC, VK1, VK2 and pantothenic acid) and calcium phosphate
Since calcium carbonate is strongly alkaline, the above-mentioned vitamins and the like are easily destroyed in an alkaline environment.
9 certain vitamins (VA, VD, VE, VB1, VB2) and ferrous sulfate, ferrous chloride, ferrous sulfide
If used at the same time, the former will speed up the oxidation process of the latter.
10 certain vitamins (VA, VK3, VB1, VB6, folic acid) and compounds containing iron, zinc, copper, manganese, iodine, etc.
