ZINC BACITRACIN (BACIFERMR) FOR YOUNG AND FOR '
GROWING-FINISHING .SWINE/I. Of Fo i-6

G. E. Combs and H. D. Wallace2/


The importance of including antibiotics in swine diets as a method of
increasing rate and efficiency of gain has been well documented for many years.
Several reports indicate that higher levels than previously used may now be
required to obtain the same benefits.

This study was conducted to evaluate the performance of pigs when relatively
high levels of Baciferm were included in the diet.

Experimental

Two experiments were conducted with pigs self-fed in expanded metal or
concrete-floored pens. Water was supplied by automatic watering devices.

Experiment 1. Thirty pigs weighing initially 14.5 pounds were allotted to
3 dietary treatments consisting of Baciferm at levels of 0, 20 and 80 gm. per
ton of feed. The experiment was terminated after 42 days.

Experiment 2. Forty five pigs weighing an average of 65 pounds were
individually fed for a 12 week period. The 5 dietary treatments were: gm/ton
Baciferm, 0, 10, 20, 40 and 80.

The composition of the diets for both experiments is presented in Table 1.

Results and Discussion

The results of Experiment 1 are summarized in Table 2. The gains of the
control group and those fed 20 gm Baciferm per ton were similar whereas t"e
group given 80 gm Baciferm per ton gained approximately 16% faster than the 0
or 20 gm treatment groups. Feed efficiency of the 20 and 80 gm groups was
improved 4 and 7% respectively over the 0 group.

Terre Haute, Indiana. Other articles on this subject include Res. Repts.
71-4 and 73-10. Data for this report came from Experiments 216A and 216B.

As presented in table 3 the daily gain of growing-finishing pigs was not
improved by Baciferm. The average daily gain of all Baciferm groups was 1.84
as compared to 1.89 for the 0 group. Feed required per unit gain was also higher
for Baciferm fed pigs; the average for all Baciferm groups was 2.99 as compared
to 2.87 for the 0 group.

These data show that for young pigs the high level of Baciferm (80 gm/ton)
was effective in improving both rate and efficiency of gain. With the growing-
finishing pig these same parameters were not improved by high dietary levels
of Baciferm. Most studies of this nature will show that the greatest response
is obtained with the younger pigs but it is also evident that with the young
pig higher levels of Baciferm may now be needed to obtain maximum benefits.

Summary

Two experiments were conducted to evaluate the influence of high dietary
levels of Baciferm on rate and efficiency of gain.

Young pigs fed 80 gm/ton of Baciferm gained 6. faster than those given either
0 or 20 gm/ton. Feed efficiency was improved by both the 20 and 80 gm/ton additions
with the biggest improvement (77.) occurring with the 80 gm level.

Neither rate nor efficiency of gain was improved with growing-finishing pigs
fed diets containing 10, 20, 40 and 80 gm/ton of Baciferm.

These data indicate that to achieve the maximum response to Baciferm it may
be necessary to provide higher levels than previously recommended.
