Influence of a Preservative on Bermudagrass Hay Stored with Approximately 16 and 24% Moisture Content1

Abstract

Coastcross-1 bermudagrass treated with a commercial hay preservative was baled and stored at moisture contents of 24.2 (high) and 16.0 (low) %; counterpart controls were baled and stored at 21.5 (high) and 14.9 (low) %. After 245 days of storage each hay was fed to four Jersey heifers for 56 days and digestibilities were estimated by lignin ratio. Nutrient compositions of all hays were essentially unchanged during storage. Apparent digestibilities of ether extract, crude fiber and dry matter of the treated high moisture hay were higher (P<.05) but the dry matter loss of 3.8% during storage was 310% (P<.05) of the average of the other three hays. Treatment of either high or low moisture hay failed to reduce dry matter losses during storage, raise voluntary intake, increase efficiency of utilization or improve weight gains of heifers. Intakes of the untreated high and low moisture hays were 6.2 and 5.0% more than that of treated counterparts. Gains of heifers receiving untreated high and low moisture hays were 200 and 153% of those by heifers fed treated counterpart hays.
