Sodium citrate at levels of 1.5 to 4.5 per cent of the ration depressed intake of ground-pelleted hay by ewes. A study with lambs showed that 1.5 per cent sodium citrate reduced consumption, whereas levels of 3.0, 4.5 and 6.0 per cent had no effect.

Distribution of potassium (K), calcium (Ca), and magnesium (Mg) in timothy and bromegrass cut at eight progressive dates was similar in both grasses. Highest concentrations were usually found in leaves, lowest at the base of stems, with levels in ste
