DDGS AND POULTRY FEED.
Distillers Dried Grain with Solubles (DDGS) is the result of extracting ethanol from grains through dry milling.The corn kernel, which is a source of food for humans and animals, its also a source of ethanol, a fuel source. Dried distillers grains with solubles (DDGS) offer nutrients and energy, DDGS can be sourced from corn, rice, wheat, sorghum and are highly useful for livestock and poultry. Ethanol producers only use the carbohydrate fraction of the corn kernel. The protein, fiber, minerals, and vitamins are returned to the animal food system in the form of distillers’ grains which are fed to beef cows and swine.This results in millions of tons of high protein animal feed and although 40% of the crop is often cited as the amount of corn used for making ethanol . DDGS derived from corn is an excellent feed ingredient for use in layer, broiler, duck and turkey diets and contains approximately 85% of the energy value in corn, has moderate levels of protein and essential amino acids, and is high in available phosphorus. DDGS from corn in the ethanol industry are considered to be waste,(distillers) but can still have a use as a feed ingredient. It is a very cheap source of crude protein, crude fibre, available phosphorous, unsaturated fatty acids and essential amino acids. This is an effective alternative to soya and corn in the poultry diet with the added benefit that it reduces feed costs by replacing soya in the diet as the price of soya is very high . The inclusion of DDGS in poultry diet has many advantages; birds fed with DDGS have a better feed intake, feed conversion ratio, body weight gain. The DDGS inclusion improves meat and egg quality by enriching it with omega-3 fatty acids (Linoleic acid) which is good for heart patients. There is improved phosphorous availability and therefore there is less phosphorous excretion.This prevents environmental pollution due to high phosphorous bio availability and less exogenous phosphorous is supplemented and this reduces the feed cost.
