Study into distillers grains affect on hog growth
In studies conduction by the Kansas State University found that feeding dried distillers grains with solubles (DDGS) to nursery and grow-finish hogs had variable effects on growth performance.
A study conducted on grow-finish hogs had three different experiments:
1,050 pigs with an average beginning weight of 104.9 pounds and lasted 28 were fed diets either 0 or 15% DDGS and 0, 3 or 6% added fat.
1,038 pigs with an average weight of 102.1 pounds were divided into groups and fed diets with either 0, 10, 20 or 30% DDGS for 56 days.
Lasted 21 days and used a total of 120 grower pigs with an average initial weight of 48.7 pounds. The pigs were randomly put into different pens, each containing four feeders to determine if pigs would selectively prefer to consume diets with 0, 10, 20 and 30% DDGS.
The results suggest that DDGS from the plants evaluated in this study can be included in the diet of commercial and finishing pigs at 10-15% without decreasing performance.
Study on nursery pigs
A 22-day study conducted on nursery pigs evaluating DDGS from a different ethanol manufacturing facility from that in the grow-finish studies.
482 pigs with an average initial weight of 21.9 pounds were randomly allotted to one of two dietary treatments. The corn-soybean meal based diets contained either 0 or 10% DDGS.
The results of the study showed that nursery pigs fed 10% DDGS were on average 1.5 pounds lighter at the end of the 22 day period – meaning that pigs fed DDGS were about $0.54 less profitable.
