Modern, 21st century feed production has countless options for adding nutrients; polypeptides with phytase activity, inorganic copper chelates, or polynucleotide sequences, to name a few. But the feed producer’s weaponry still holds a place for older, low-tech nutrition: phosphate feed additives. Today, dicalcium and monocalcium phosphate are still popular choices for feed supplementation, just as they were when they were first developed over sixty years ago.

Amino acid is the basic unit of protein. It is an organic acid containing amino group. It is composed of carbon, hydrogen, oxygen and other elements. The protein in the feed cannot be directly used by animals, but is decomposed into peptone and peptides by the combined action of digestive enzymes such as pepsin and trypsin, and cannot be used by the organism until the simplest amino acid. Therefore, protein nutrition is actually amino acid nutrition.

Trace elements play a very important nutritional value in animal feed. The importance of trace elements in feed cannot be underestimated, but if it is not added scientifically, the proportion is unreasonable, and small or excessive additions will not play a nutritional role. It may even have a counter-effect, and in severe cases, it may cause symptoms of poisoning in the fed animals.

Trace elements are nutrition elements that occupy a very small share in the feed but are not available. However, because the share is too small, they are often ignored. Trace elements play a key role in the growth and reproduction of pigs. The amount of additions will be discussed with everyone.
