Mineral nutrition of pigs

Last Updated: 2024/11/05, It has been proved that there are more than 40 kinds of essential mineral elements in pigs, which can be divided into two categories: major elements and trace elements according to their content in pigs. Elements with a content of more than 50 mg / kg are major elements, which are mostly expressed by percentage content; elements less than 50 mg / kg are mostly represented by mg / kg. Pigs need at least 14 inorganic elements, including major elements calcium (Ca), phosphorus (P), sodium (Na), chlorine (Cl), potassium (K), sulfur (S), magnesium (Mg) and

It has been proved that there are more than 40 kinds of essential mineral elements in pigs, which can be divided into two categories: major elements and trace elements according to their content in pigs. Elements with a content of more than 50 mg / kg are major elements, which are mostly expressed by percentage content; elements less than 50 mg / kg are mostly represented by mg / kg.

Pigs need at least 14 inorganic elements, including major elements calcium (Ca), phosphorus (P), sodium (Na), chlorine (Cl), potassium (K) sulfur (S), magnesium (Mg) and trace elements iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), iodine (I), selenium (Se) and cobalt (Co). In addition, other elements such as arsenic (As), bromine (Br), chromium (Cr), boron (B), cadmium (Cd), fluorine (F), lead (Pb), lithium (Li), molybdenum (Mo), nickel (Ni), silicon (Si, tin (Sn) and vanadium (V) may also be necessary for pigs.

The raw materials of non-mineral feed for pigs generally contain all kinds of mineral elements, but the amount provided by most raw materials can not meet the nutritional needs of pigs. and all kinds of plant raw materials show obvious regional differences due to the influence of growing water, soil, climatic conditions, industrial pollution, breeds, production seasons and harvest time, so minerals and trace elements should be reasonably supplemented according to the local actual conditions.
