GRAIN SORGHUM IN SWINE STARTER, GROWER AND FINISHER DIET1

SHUME LIBRARY

Grain sorghums have the potential of becoming an economical feed i red~int
for Florida swine producers. Included among the sevel lEt4d1aO s s c ng
their extensive usage is the comparatively large amou asked feed
required per unit gain.

This experiment was conducted primarily to determine the extent of the in-
crease in feed efficiency resulting from the supplementation of sorghum diets
with three percent fat.

Experimental

Ninety pigs weaned at three weeks of age were allotted according to initial
weight, litter and sex to five treatment groups. Each of the groups consisted
of three pens containing six pigs each.

The diets were calculated to
six week period.


Grower-finisher period. During this period, the pigs were housed on
aluminum slats in a partially enclosed building. The grower diet contained
approximately 15 percent protein and was fed until the pigs averaged 125 pounds
body weight. At this time, the dietary protein was reduced to 13 percent for
the remainder of the experiment.

Automatic watering devices and self-feeders were used during all periods
of the experiment.

The dietary treatments and composition of the diets are presented in
table 1.

Results and Discussion

A summary of the performance data is presented in table 2.

Average daily gain was not significantly (P<.05) affected by dietary treat-
ment. However, a comparison of the gains made by pigs fed corn or NBR sorghum
shows a 6 percent improvement for the corn groups. The addition of 3 percent
fat to the NBR sorghum diet resulted in a slight improvement of gain but remained
less than that of the corn groups. An explanation for the 5 percent reduction

in gain resulting from the addition of 3 percent fat to the corn diet is not
readily apparent.

Feed efficiency data did not show significant (P<.05) differences among
treatment groups although the treatments that received 3 percent supplemental
fat required less feed per unit gain than the other groups. The extent of
this decrease varied but was greatest with the group fed NBR sorghum plus 3
percent fat. This finding is of particular importance since comparisons of
corn and sorghum based diets often show similar growth responses but the
corn usually permits a more efficient gain.

Summary

An experiment involving 90 early weaned pigs was conducted to compare
corn and sorghum as energy sources in starter, grower and finisher diets.
Diets were formulated with corn and sorghum as isonitrogenous ingredients and
fed with and without 3 percent supplemental fat. Daily gain and feed efficiency
was not significantly (P<.05) different among treatment groups.
