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:
Experiment One

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.

Experiment two


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.

Experiment three


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.

Conclusion

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.
Experiment

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.
