Utilization Of Distillers Dried Grains For Fish Feed By Extrusion Technology—A Review, Nehru Chevanan, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Protein-rich distillers dried grains (DDG) from ethanol plants has been used as livestock feed for many years. Feed conversion efficiency in fish, however, is typically much higher compared to traditional livestock. But, the cost of fish feed is one of the challenges for profitable fish cultivation. Due to the exponential growth of ethanol plants in recent years, DDG is becoming readily available as a reasonably-priced base material for animal feeds, and because it has a relatively high protein content, it also has much potential for use as a fish feed ingredient. Even though much literature is available on conversion of …

Distillers’ dried grains with solubles (DDGS) from ethanol manufacturing plants contain a high percentage of protein, and are primarily used as livestock feed. The conversion efficiency of feed into body tissue is generally much higher in fish than farm animals. Fish can convert up to 36% of feed protein into body protein, whereas beef typically converts only 15%. Extrusion technology is very widely used for the production of floating and non floating aquaculture feeds. Therefore, the objective of this study was to quantify physical properties of extrudates containing 20,30 & 40% DDGS and net protein content adjusted to 28%. Three …
