Milo Stover and Sources of Supplemental Nitrogen for Growing Beef Heifers and Lambs1

Abstract

Three growth and two digestion trials were conducted to determine the feeding value of milo stover. In the two cattle growing trials, performance of heifers fed forage sorghum silage was significantly greater than that of heifers fed milo stover silage or milo stover pellets. Heifers fed milo stover pellets consumed more dry matter and required more feed per unit of gain than those fed forage sorghum or milo stover silages. In the lamb growing trial, those fed milo stover pellets gained faster (.11 vs .02 kg/day), consumed more dry matter (1.30 vs .59 kg/day) and gained more per kg of feed (.08 vs .04 kg) than those fed milo stover silage. Lambs fed either milo stover silage or pellets supplemented with soybean meal (SBM) or SBM-corn gluten meal (CGM)-urea gained faster and more efficiently than lambs fed urea or biuret supplemented rations.

In the first digestion trial, lambs fed SBM or SBM-CGM-urea retained more nitrogen than lambs fed urea or biuret; those fed milo stover pellets had a lower crude protein digestibility (61.9 vs 64.2%) but retained more nitrogen (.81 vs .08 g/day) than those fed milo stover silage. In the second lamb digestion trial, increasing milo stover pellet intake by 43 and 86% decreased ration dry matter and crude protein digestibilities.
