ABSTRACT

Two total-collection digestion trials were employed to ascertain the influence of nitrogen fertilization rate, harvest date, and level of intake on the nutritive value of Climax timothy hay. Two plots of timothy were fertilized at two levels of nitrogen per acre, 34.1 kg and 56.8 kg, respectively. One half of each plot was harvested on June 15 and the remainder on June 25. The four hays were fed to wethers at two levels, limited and ad libitum plus 10% refusal. Intake levels and protein and energy digestibilities were determined for each of the treatment forages.

Consistent results were found with respect to: 1) Nitrogen fertilization did not significantly influence forage composition. 2) Harvest date exerted a highly significant difference in forage crude protein content and energy digestibility. 3) Significant differences were found in forage intake levels between harvest dates. 4) The ad libitum feeding rate caused a significant depression in energy digestibility compared to the limited feeding rate.
