OBJECTIVE:
To develop a comparison between Masterfeeds Tend-R-Leen
and that of New Life Mills 13% Beef Gainer programs
reflecting the growth performance and cost per pound of gain
when feeding heavyweight heifers.
METHODS:
Randomly 303 crossbred heifers were divided into six
groups in a slatted barn. All six groups were started on the
NLM starter ration and transitioned onto the NLM 13% Beef
Gainer according to the NLM program. During the first week
on the NLM 13% Beef Gainer ration the cattle in pen four
were switched to a blend of 50:50 NLM and Tend-R-Leen
ration. At the start of the 2nd week, pen four was switched
100% to the Tend-R-Leen ration.
The Tend-R-Leen ration contained 7% Tend-R-Leen SDA
supplement and 93% Whole Corn. Mixing of the corn and
Tend-R-Leen was done on-farm and a mixing charge of $10.00/t
was included in the calculations. Medication in both feeds
on a complete diet was rumensin (33ppm monensin), tylan (11
ppm tylosin), and MGA (0.4 mg/day). Vitamin E was fed at 500
IU/day. Cattle were implanted with Synovex Plus at the start
of the trial. The NLM cattle stayed on feed 11 days longer
due to logistical reasons.

If all the cattle had been fed on the Tend-R-Leen
program, the additional revenue would have been $13,915.00.
