Abstract
An experiment was designed to test the value of Ulva lactuca, produced from an integrated mariculture project, using six Finn-Merino crossbred ram lambs. Diets consisted of concentrate with vetch hay for the control, with additional Ulva for the treatment diet. Measurements of digestibility of energy, volatile fatty acid concentration in the rumen fluid, effective degradability of nitrogen in the rumen, rumen ammonia concentration and excretion of nitrogen in urine all indicated that Ulva could be categorized as a low-energy high-nitrogen foodstuff.
