Feeding Value of Corn and Sorghum Silage for Milk Production

Abstract

Corn, and one or more varieties of sorghum, were grown for silage in alternate strips in the same field in three tests. The yield of corn was considerably less than any variety of sorghum each year, especially during the dry summer of 1954. One double-reversal and two Latin-square design feeding trials were conducted with from 22 to 27 cows in each test, to compare silage from these crops. Cows produced more milk, consumed more silage, and gained more weight each year on the corn silage than on any variety of sorghum. These differences were highly significant (P < 0.01). Milk produced by cows receiving Tracy, sorghum had a stronger silage flavor than that produced by any other type of silage fed. © 1957, American Dairy Science Association. All rights reserved.
