USE OF FLORIDA GROWN WHEAT IN YOUNG PIG DIETS1

G. E. Combs and H. D. Wallace2


Although wheat is generally considered an energy source it must also be
recognized as a major contributor of dietary protein and amino acids. The
protein content of the various types of wheat ranges from approximately 10
to 16 percent with lysine being the most limiting amino acid. Formulations
that utilize total protein and consequently use less protein supplement often
fail to produce optimum performance since this practice decreases the quantity
of dietary lysine.

The present study was conducted with young swine to compare the feeding
value of Florida grown soft winter wheat and corn. The comparison was made
with wheat diets that contained either an amount of soybean meal or dietary
protein equal to that present in the corn diet.

Experimental

Forty-five pigs weaned at approximately 3 weeks of age were allotted to
3 treatment groups. All pigs were housed in expanded metal cages equipped with
self feeders and automatic watering devices. The dietary treatments were as
follows:

(1) Corn-soybean meal ,
(2) Wheat replaced corn equal soybean meal
(3) Wheat replaced corn equal protein

The composition of the experimental diets is shown in Table 1.

Results and Discussion

The performance data are summarized in Table 2.

The daily gain of the pigs fed the corn-soy diet and those given the wheat-
equal soy diet was equal whereas gain was significantly (P < .01) depressed with
the wheat-equal protein diet. Feed required per unit gain was similar with the
corn-soy and wheat-equal soy groups. The wheat-equal protein treatment required
approximately 22 percent more feed per unit gain than the other groups.

The average reduction in gain for the wheat-equal protein group was 38
percent and as shown in Table 2 this reduction was consistent in all replications.
These data indicate that Florida grown soft winter wheat is a satisfactory replace-
ment for corn in pig starter diets provided that sufficient protein supplement is
used to adequately compliment the amino acids present in wheat.
Summary

Forty-five early weaned pigs having an initial weight of about 13 pounds
were fed diets containing either corn or wheat with equal quantities of soybean
meal or wheat with sufficient soybean meal to provide dietary protein equal to
that of the corn-soybean meal treatment. Rate of gain was equal with the corn
or wheat equal soybean meal groups but reduced 38 percent when the dietary protein
of the corn and wheat group was equal; feed efficiency was also depressed by
this latter treatment. Florida produced soft winter wheat may be satisfactorily
used in pig starter diets provided its amino acid content is properly considered.
