A STUDY OF COPPER SULFATE AND OTHER FEED ADDITIVES
FOR YOUNG PIGSL'

H. D. Wallace and G. E. Combs2/


This experiment was undertaken to determine the relative effectiveness of sev-
eral feed additive preparations when included in the diet of the young pig. Copper
sulfate, a combination of aureomycin, penicillin and sulfamethazine, a combination
of terramycin and neomycin, and a combination of terramycin, furazolidone and arsa-
nilic acid were compared.

Experimental

One hundred, three-week-old crossbred pigs (Duroc-Landrace x Hampshire) were
divided into outcome groups according to weight, litter and sex and allotted to
twenty pens of five pigs each. Four pens of pigs were fed on each of the dietary
treatments shown below.

1. Basal

2. Basal + 250 ppm copper as copper sulfate

3. Basal + 100 gm. aureomycin, 100 gm. sulfamethazine and 50 gm. penicillin
per ton of feed.

4. Basal + 100 gm. terramycin and 50 gm. neomycin per ton of feed.

5. Basal + 100 gm. terramycin, 100 gm. furazolidone and 90 gm. arsanilic
acid per ton of feed.

Two basal diets were involved in the study with the pigs equally divided by treat-
ment pens between the two basal diets. The compositions of these basal diets are
shown in Table 1. All pigs were fed ad libitum by self-feeder in concrete floored
pens and water was supplied by automatic waterers. The pigs averaged approximately
12 Ibs. liveweight initially and the feeding experiments lasted 8 weeks.

Research Association, Inc., New York, N.Y.; American Cyanamid Co., Princeton,
N.J.; and Chas. Pfizer and Co., Inc., Terre Haute, Ind.

pantothenic acid, niacin and choline.chloride.

3/ Contained a minimum of 20 mg. B12 per lb.

4/ Contained 14 gm. vitamin A (10,000 IU/gm.), 2 gm. vitamin D (9,000 IU/gm.) and
438 gm. yellow corn.



Results and Discussion

Average daily gains and feed requirements per pound of gain are presented in
Tables 2 and 3 respectively. The relative performance of all pigs on each of the
basal diets is presented and discussed in a previous report (1).

The most effective additive was the combination of terramycin, furazolidone
and arsanilic acid. This combination improved gains approximately 20%, which was
a highly significant effect statistically. This combination also induced the great-
est saving in feed per unit of gain, approximately 7-1/2%. Copper sulfate and the
combination of aureomycin, sulfamethazine and penicillin induced a 15% improvement
in gain (P < .05), and feed conversion was improved by each of these treatments.
The pigs fed copper sulfate showed no evidence of toxicity. The combination of
terramycin and neomycin did not elicit a statistically significant improvement in
gain. However, it can be seen that a small but consistent response was evident in
all of the replications. This combination recorded a 3-1/2% saying in amount of
feed required per unit of gain.

Summary

A feeding experiment, involving 100 early weaned pigs, was conducted to study
the supplementary feeding value of various feed additive preparations.

Copper sulfate, a combination of aureomycin, sulfamethazine and penicillin and
a combination of terramycin, furazolidone, and arsanilic acid all improved weight
gain significantly. The latter preparation was the most effective.
