High-Moisture Shelled Corn as Compared to
Regular Shelled Corn With and Without Antibiotics For Growing-Fattening Hogs
J. H. Conrad and W. M. Beeson
Department of Animal Husbandry
Before shelled corn can be stored in ordinary bins, it must be dried so that it con-ains not more than 13$ moisture. Preserving high-moisture shelled corn (28$ to 32$
*ater) by storing it in an airtight glass-lined silo would eliminate drying the corn before storing. If high-moisture corn were stored in this way, would its feeding value be less, the same or more than regular shelled oorn (13$ to 18$ moisture)?
This experiment was designed:
(1)	To determine the relative feeding value of ensiled shelled corn (31»8$ moisture) with regular shelled corn (18.5$ moisture) produced from the same fields for growing-fattening hogs.
(2)	To study the effect of antibiotics (penicillin or terramycin) when fed to growing-fattening hogs.
(3)	To compare penicillin and terramycin as antibiotics for growing-fattening hogs.
Experiment Plan
Seventy-two weanling pigs, 8 to 9 weeks of age and averaging 40 pounds, were allotted to 6 lots on the basis of age, sex, liveweight and general appearance. All pigs were fed | free-choice shelled corn and protein supplement in drylot. The experiment was started on November 1, 1955«
Three lots were fed high-moisture shelled corn (31.8$ moisture) and 3 lots were fed regular shelled corn (18.5$ moisture). The three lots on each of the shelled corn treatments were fed no antibiotic, 50 grams of penicillin per ton of protein supplement or 50 gams of terramycin per ton of protein supplement. Details of the protein supplements fed are given in Table 1.
The experimental treatments were as follows:
High moisture shelled corn (31«8$ moisture)
Lot 1:	Supplement 2, No antibiotic
Lot	2:	Supplement	2	/~50	grams	of	penicillin	per	ton
Lot	3:	Supplement	2	/ 50	grams	of	terramycin	per	ton
Regular shelled corn (18.5 percent moisture)
Lot 4:	Supplement 2, No antibiotic
Lot	5:	Supplement	2	/~50	grams	of	penicillin	per	ton
Lot	6:	Supplement	2/50	grams	of	terramycin	per	ton
The high moisture shelled corn was taken from the silo and put in a self-feeder every day or every second day depending on the corn consumption of the pigs. However, both <inds of corn were fed free-choice, but it was necessary to feed the high-moisture shelled corn at frequent intervals to avoid spoilage in the feeder. In spite of these precautions, there was some molding and spoiling of the high-moisture shelled corn after it was placed in the feeder. This may have reduced its feeding value. Probably feeding the com twice daily would be preferable.
