A Preliminary Report on the Value of Zymo-Pabst
in Fattening Rations fed to Steers, on Pasture 1/ 2/


H. L. Chapman, Jr., and C. E. Haines 3/

Zymo-Pabst is a multiple-enzyme supplement. Its enzyme activity is of
bacterial and plant origin. It contains enzymes which assist in the break-
down of proteins and starched. It is available commercially as a dry, free-
flowing powder which can be mixed into concentrate feeds. Results of research
with enzymes as feed-additives have been variable. However, there have been
some indications that Zymo-Pabst has been of value to cattle being fattened in
dry lot. The purpose of this study was to investigate the value of the enzyme
preparation to steers being fed a concentrate mixture on pasture.


This study was conducted as a field study, in cooperation with a local
cattle feeder. The enzyme preparation was simply superimposed upon the stan-
dard feeding program followed by the producer in his grass-fattening operation.

One hundred long-yearling steers of Brahman x English breeding and with
an average initial weight of 718 pounds, were divided into two groups of 50
steers each. They were allotted to the experimental treatment at random and
fed for a 91-day period. The concentrate feed was a commercially prepared
mixture normally used in the feeding program of this feeder. The feed ingre-
dient composition is presented in table 1.

1/ Zymo-Pabst was furnished by Pabst Brewing Company, Milwaukee, Wisconsin.

2/ The cooperation of Mr. Chris Figuero of Seralles Ranch, Belle Glade,
Florida in the conduction of this experiment is great l iated.
Also, the authors wish to acknowledge the assistance5e'tfto ed
Mills, Deerfield Beach, Florida in mixing the expe 'tal rations

The only difference in the two feed mixtures was that Zymo-Pabst was
included in one ration to furnish an average daily intake of 3 grams of
the enzyme preparation per animal. During the first 30 days of the
experiment the steers received an average daily feed intake of four pounds.
At the end of thirty days the average daily intake was increased to 8
pounds per animal. The enzyme was kept constant at the 3 gram daily average

Each group of fifty steers were placed in a fifty acre pasture.
The pastures were a mixture of Roselawn St. Augustine and Bermuda grasses,
and were comparable in quality. The steers were fed once, daily, in
wooden feed troughs. They were weighed at thirty day intervals.


As shown in table 2, the steers receiving the no-Zymo-Pabst ration
had an average daily gain of 1.16 pounds, as compared to 1.23 pounds for
the steers receiving the enzyme preparation.

Table 2. Summary of weight gain and feed consumption for steers
receiving Zymo-Pabst as compared to those not receiving
the enzyme mixture. (91 days on experiment)

No Zymo-Pabst Zymo-Pabst

Average initial Weight (lbs.) 713 721
Average final weight (Ibs.) 819 833
Average total gain (Ibs.) 106 112
Average daily gain (Ibs.) 1.16 1.23
Average total feed consumption (Ibs.) 608 608
Average daily feed cons. (Ibs.) 6.68 6.68

Average feed/lbs. gain (Ibs.) 5.76 5.43
Average cost of feed/lb. ($) .029 .029
Average feed cost/lb. of gain ($) 16.7 15.7
Average enzyme cost/day (0) -- 1.25
Average enzyme cost/lb. gain (1) --- 1.01
Average total feed cost/lb. gain 16.7 16.7

Less feed was required per pound of gain for the animals receiving
Zymo-Pabst. The cost of the 3 grams of Zymo-Pabst was 1.25 cents per
steer daily on the basis of these gains and the enzyme cost there was
no difference in average total feed cost per pound of gain between the
two treatments. This was 16.7 cents, for each test group.
