The nutritive value of hays made from Cassia rotundifolia cv. Wynn and Medicago sativa cv. Trifecta (lucerne) was compared in 2 experiments. In the first experiment, 16 adult wether sheep were fed (ad libitum) either cassia hay or lucerne for 35 days. Digestibilities of dry matter and nitrogen in the cassia were 55 and 66% respectively. Both values were significantly (P < 0. 05) less than the corresponding values for lucerne hay (65 and 81% respectively). Sheep fed cassia hay exhibited significantly lower (P < 0. 05) nitrogen retention than animals offered lucerne hay (5.4 versus 24.6 gN/d).
