Necessity of liquid coating for Animal Feeds

The use of liquid ingredients in animal feed production is increasing dramatically as an ever increasing range of products becomes available. The most common types of liquid ingredients used in animal feed production today are fats, vitamins, minerals, antibiotics, amino acids and enzymes. Of these ingredients the group of products which has probably created greatest interest in the industry in recent years is enzymes. In terms of animal feeds which are predominantly composed of cereals and vegetable proteins, a large portion of these ingredients can not be fully digested by mono-gastric animals. Much of the energy available is locked up in the form of non-starch poly-saccharides (NSP) that mono-gastric animials are unable to digest. Similarly most plant materials used in animal feeds contain the mineral phosphorus which is bound in the form of phytic acid and can not be degraded by mono-gastric animals. External enzymes added directly to feeds act as supplements to the normal digestive enzymes already found in the animalí»s digestive system. The idea of using enzyme supplements is to increase digestibility, facilitating better utilization of feeds. The greater the utilization of the feed the better the animal performance and the lesser the load on the environment in terms of manure or waste. In short, the use of micro-ingredients such as vitamins, minerals, amino acids, antibiotics and enzymes and their variability to the animal feed in exact amounts is playing an increasingly important role in efficient animal production, not only from an economic point of view but also from an environmental point of view.
