A STUDY OF CORN DISTILLERS' DRIED SOLUBLES AND
DISTILLERS' DRIED GRAINS WITH SOLUBLES ADDED AS SOURCES OF
UNIDENTIFIED NUTRITIONAL FACTORS FOR THE PIG V/

H. D. Wallace and G. E. Combs 2/


In the 1940's and early 1950's distillers' dried solubles was established as
a good source of dietary protein and B-complex vitamins for the pig. More recently,
interest in this feed product has centered around its content of unidentified nutri-
tional factors. In' 1960 an experiment was initiated at this station to determine if
distillers' dried solubles would improve the reproductive performance of sows fed
and managed under practical farm conditions. A preliminary summary of this experi-
ment is presented in the Proceedings of the 1964 Distillers' Feed Research Conference
(I). It has been observed that supplemented sows farrowed slightly more live pigs
per litter (11.06 vs. 10.70) and weaned slightly more per litter (9.67 vs. 9.38).
There has been no indication that the supplementary solubles has stimulated milk
flow or influenced the survivability of pigs.

The present study was undertaken with two objectives in mind:

1. To compare corn distillers' dried solubles and distillers' dried grains
with solubles added as sources of nutritional factors for the pig.

2. To determine if the continuous feeding of corn distillers' solubles to
sows would produce desirable carry-over effects in pigs farrowed by the
sows.

Experimental

Ninety, three-week-old crossbred pigs (Duroc-Landrace x Hampshire) were divided
into outcome groups according to weight, litter and sex and then allotted to 18 pens
of five animals each. Nine pens of pigs were from litters whose dams had been on a
continuous solubles supplementation program. The other 9 pens of pigs were from sim-
ilar sows which had not been fed solubles. The composition of the diets fed to the
various pens of pigs is shown in Table I. All pigs were fed ad libitum by self feed-
er in concrete floored pens and water was supplied by automatic waterers. The pigs

averaged approximately 10 Ib. initially and were individually removed from the ex-
periment when they reached approximately 200 Ib. liveweight.

Results and Discussion-

The average daily gains for the first eight weeks of the feeding trial are
summarized in Table 2. The addition of either dried corn distillers' solubles or
distillers' dried grains with solubles added depressed rate of gain during this
period (P< .05). This was a consistent observation for all replicates and occurred
irrespective of the source of pigs. The pigs from sows which had been fed solubles
gained 1.23 lb. per day compared to 1.20 for pigs from control sows. This differ-
ence was not significant.

A part of the feed records for this early feeding period were accidentally des-
troyed and thus it is not possible to present a complete and accurate feed data sum-
mary. The records that are available indicate no marked differences in feed intake
or efficiency of feed utilization and are generally in accord with the gain data.

Average daily gains and feed conversion data for the finishing phase of the ex-
periment are presented in Tables 3 and 4 respectively. There were no consistent pat-
terns evident in the gain data. Pigs fed':he basal diet and the diet supplemented
with dried grains and solubles gained slightly better on the average than the group
supplemented with solubles only. As in the early phase of the feeding trial, the
source of pigs did not significantly influence rate of gain. The overall averages
for feed conversion showed that differences due to feeding treatment were not sig-
nificant nor was the difference due to pig source significant.

Summary

A feeding experiment, involving ninety pigs, was conducted to compare dried
corn distillers' solubles and dried distillers' grains with solubles as sources of
unidentified growth factors for the pig. Both feed products, when added at a level
of 5% to the diet, reduced rate of gain during the early growth period from 8-11
weeks of age. During the finishing period neither product significantly affected
rate or efficiency of gain.

A second objective of the experiment was to study possible nutritional carry-
over effects in pigs resulting from the continuous feeding of dried corn distillers'
solubles to the sows. The results indicated that pigs from supplemented and non-
supplemented sows performed at about the same level during the growing-finishing
period.
