Swine production in Thailand has developed tremendously in the past two decades. At present, only high performing animals are raised commercially. These high performing animals are more prone to stress and have lower ability to digest low quality feed. They require not only a higher nutrient density diet but also a diet with better digestibility and lower crude fiber level.
Soy products, composed of soymeal and extruded fullfat soy, have become major protein sources in animal diets since they are high in protein and essential amino acids, low in crude fibre, and are easily available. However, most soymeal available to farmers in Thailand is not dehulled and has a fibre content of around 7 percent. This has contributed to a higher overall level of fibre in the diet.
Pigs do not require corn and soymeal; they require energy, amino acids, and other nutrients in adequate available amounts for normal growth. It is just in most cases that corn-soymeal diets provide the closest match to the pig's requirements at the lowest cost. However, there has been a very rapid growth of the ethanol industry in the US and other countries as well, which has resulted in an increasing amount of ethanol co-products available for livestock feed. The three main co-products of the ethanol industry are Distillers Grains, Solubles, and Distillers Grains with Solubles (DDGS), and they can be either ''wet'' or ''dried'' depending on the manufacturing process. DDGS contains the same or slightly higher energy levels than corn, but it contains approximately 27 percent protein so most people consider it a protein source.
