DRIED DISTILLERS' GRAINS WITH SOLUBLES IN PIG STARTER DIETSLI
G. E. Combs and H. D. Wallace.2/


Previous studies (1) (2) reported that the addition of 5% dried distillers'
grains with solubles (DDG/S) to starter diets reduced the rate of gain with young
pigs.

The objective of the present study was to determine if a lowered digestibility
of certain nutrients accompanied the growth depression of pigs fed diets containing
DDG/S.

Experimental

Thirty-six pigs having an initial weight of 16.5 Ibs. were individually fed
diets containing either 0, 10 or 20% DDG/S. All diets were calculated to contain
18% protein. The pigs were fed ad libitum by self-feeders in concrete floored
pens and water was supplied by automatic waterers.

During the last week of the 6 week experimental period chromic oxide was .
added to all die'ts'to facilitate determination of digestibility coefficients for :
dry matter, protein and ether extract (fat).

The composition of the diets is presented in Table 1.

'Table 1. Composition of Diets

Ground yellow corn 71.2 65.4 60.0
Soybean meal (50%) 23.5 19.3 14.7

1/ Supplied the following in ppm: Mn, 57; Fe, 70; Cu, 4.8; Co, 1.6 and
Zn, 100.
2/ The following vitamins were added to provide per pound of diet: vitamin A,
1400 I.U.; vitamin D, 400 I.U.; riboflavin, 4.4'mg.; pantothenic acid, 10
mg.; niacin, 20 mg. and vitamin B12, 10 mcg.
3/ Contained 5 gm. procaine penicillin and 15 gm. streptomycin/lb.



1/ The study was supported in part by a grant-in-aid from the Distillers Feed
Research Council, Cincinnati, Ohio.

this study.

Means on same line bearing different superscript letters differ signifi-
cantly (P < .05).


The average daily gain among the three treatment groups was not significantly
different (P < .05). The absence of a growth depressing action at higher dietary
levels of DDG/S than previously used (10 and 20% vs. 5%) may be attributed in
part to a difference in initial age of the pigs. In the previous studies the
pigs were 21 days of age when put on test whereas in the present study the pigs
averaged about 30 days of age. The daily feed consumption and feed required per
pound of gain were also similar for all dietary treatments.

The digestibility of dry matter tended to decrease with increasing levels
of DDG/S. The coefficients for pigs fed 0 or 10% DDG/S diets were significantly
(P < .05) higher than that for pigs fed the 20% DDG/S diet. Digestibility of
protein and fat also decreased with increasing levels of DDG/S. But only the 0
and 20% DDG/S diets were significantly (P < .05) different.

Summary

Thirty-six pigs were housed in individual concrete floored pens and fed
diets that contained 0, 10 or 20% dried distillers' grains with solubles for a
42 day period.

Neither daily gain, daily feed or feed efficiency was significantly (P < .05)
influenced by the addition of DDG/S to pig starter diets.

Dry matter digestion was significantly (P < .05) lower in pigs fed the 20%
DDG/S diet than with pigs fed either the 0 or 10% DDG/S diet. The pigs fed the
highest level of DDG/S also had significantly (P < .05) lower digestion coefficient
for protein and ether extract than found with pigs given the 0 level of DDG/J.
