Cattle Feed (DDGS)

Give your livestock the nutrition they need to thrive with QTI's premium cow food.

Cattle Feed (DDGS)

DDGS is an excellent source of digestible protein and energy for cattle. It is highly palatable with a good source of readily available low-cost organic phosphorus and high in protein.The high energy level of DDGS is derived predominantly from fibre and fat and does not cause any risk of developing acidosis.

Distiller’s Dried Grains with Soluble (DDGS) is the dried residue remaining after the starch fraction of maize (Corn DDGS) is fermented with yeasts to produce ethanol. Following fermentation, the ethanol is removed by distillation and the remaining fermentation residues are dried.

Rice DDGS is a by product of alcohol manufacturing process. Distillers extract the starch from grains to process into alcohol and the nutrients that are left over largely comprise of essential proteins, fat, vitamins that are in favour with poultry & cattle feed. Rice DDGS is good source of energy, protein, phosphorus.Distillers Dried Grains with Solubles (DDGS) has always been an alternative feed ingredient. It can be used as an alternate protein source as it is has a crude protein of around 40 – 45 % and gross energy of around 3800 – 4200 kcal/ kg can be used in commercial broiler chicken ration.

What is the manufacturing process of rice DDGS?

The DDGS production process

It begins by grinding the grains into a coarse consistency. Hot water turns the starch in the grains into sugar, and yeast allows the mixture to ferment. The solids that remain after fermentation are called distillers' grains.

About manufacturing process of rice DDGS

Rice DDGS (Distillers Dried Grains with Solubles) is a byproduct of the ethanol production process, obtained by drying the leftover solids after the fermentation of rice. Rice DDGS is a high protein and high energy feed ingredient, commonly used in the livestock and aquaculture industries. In this blog, we will discuss the manufacturing process of Rice DDGS, from rice grain to the final product.

Step 1: Rice Cleaning and Preparation

The first step in the production of Rice DDGS is to clean and prepare the rice grain. The rice is thoroughly cleaned and sorted to remove any impurities, such as dirt, stones, and other foreign material. The cleaned rice is then soaked in water for several hours to increase its moisture content, which is necessary for the fermentation process.

Step 2: Rice Grinding and Cooking

After the rice has been soaked, it is ground into a fine powder using a hammer mill or a roller mill. The ground rice is then cooked in a steam cooker to break down the starch into simple sugars, which can be easily fermented by the yeast. The cooked rice is then cooled and transferred to the fermentation tanks.

Step 3: Fermentation

The cooked rice is mixed with water and yeast in a fermentation tank. The yeast consumes the sugars in the rice, producing ethanol and carbon dioxide. The fermentation process typically lasts for 24 to 48 hours, depending on the desired ethanol concentration. After the fermentation is complete, the resulting mixture is called “beer.”

Step 4: Distillation

The beer is then sent to the distillation column, where the ethanol is separated from the water and other impurities. The distillation process produces a concentrated ethanol solution, which is typically around 95% ethanol by volume.

Step 5: Drying

The leftover solids from the distillation process, known as “stillage,” are sent to the dryer. The dryer removes the remaining moisture from the stillage, resulting in a dry powder known as “wet distillers’ grains.” This product is then further dried to produce Rice DDGS.

Step 6: Pelletizing and Packaging

The Rice DDGS is then pelletized and packaged for transport and storage. Pelletizing the Rice DDGS makes it easier to handle and transport, and also increases its shelf life. The pellets are typically packaged in bags or bulk containers, ready to be shipped to feed mills or directly to livestock and aquaculture producers.
Benefits of Rice DDGS

Rice DDGS is a valuable feed ingredient for livestock and aquaculture, as it provides several nutritional and economic benefits.

High Protein Content

Rice DDGS is a rich source of protein, containing around 25-30% protein on a dry matter basis. This makes it an ideal ingredient for livestock and aquaculture diets, as protein is essential for growth and development.

High Energy Content

Rice DDGS is also a high-energy feed ingredient, containing around 10-12% fat and 65-70% total digestible nutrients (TDN) on a dry matter basis. This means that it provides a significant amount of energy to animals, helping to support their metabolic needs.

Cost-Effective

Rice DDGS is a cost-effective alternative to traditional feed ingredients, such as soybean meal and corn. It is often cheaper than these ingredients, making it an attractive option for livestock and aquaculture producers looking to reduce their feed costs.

Environmentally Friendly

The production of Rice DDGS is an environmentally friendly process, as it makes use of the byproducts of ethanol production. This helps to reduce waste and conserve resources, making Rice DDGS a sustainable feed ingredient.
