Relative Value of Low-Moisture Corn and Ensiled High-Moisture Corn for Feeder Lambs¹

University of Minnesota, St. Paul

Abstract

Three trials involving 175 feeder lambs were conducted to determine the relative value of ensiled ground ear corn and ensiled shelled corn as a concentrate for fattening lambs. In addition, an attempt was made to determine the "effects" of drying and ensiling on the feeding value of both types of corn.

Neither shelled corn nor ground ear corn had an increased nutritive value for feeder lambs when it was ensiled. Ensiling corn which was already dried did not cause any significant change in its nutritive value as measured by lamb growth response. Apparently the ensiling of ground ear corn does not cause an appreciable change in the utilization of the cob portion by lambs.

The difference in chemical composition of the dry matter of dried corn and ensiled corn is not clearly shown. Microbiological analysis of the two types of ensiled corn revealed that drying reduced appreciably the number of bacteria, yeasts and molds.
