Adding amino acids to animal feed can meet animal protein requirements and improve feed utilization. And can also reduce the stress of animals and so on. As an animal feed additive, amino acid has a great effect, and its price is high, so it should be selected reasonably when used, so as not to affect the feed quality and cause economic loss.
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.
Protein feeds are feeds containing less than 18% crude fiber and 20% or more crude protein in dry matter. Compared with energy feeds, this type of feed has a high protein content and good quality, but it is different in energy No. The price of protein feed is generally high, and the proportion of animal feed is also small. It is only used as a protein supplement.
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.
