Abstract Dry biomass of the halophyte Salicornia bigelovii was substituted for rhodesgrass as the forage component (approx. 50% as consumed) of diets fed to Damascus kid goats in the United Arab Emirates. Because of the high NaCl content of the biomass it was tested in two forms designed to bring the NaCl content within acceptable levels. In one treatment it was presented in a 1:1 (w/w) mixture with rhodesgrass to dilute the NaCl content. In the second treatment the S. bigelovii biomass was washed in seawater, pressed and redried to reduce the NaCl content; it was presented as the sole forage component in that treatment. The washing procedure reduced the NaCl content of the S. bigelovii biomass by approximately half, from 23-30% to 8-13%, but also removed cell solubles. There were no significant differences (P < 0.05) among diet treatments in weight pins of animals, which ranged from 63 to 90 g day-1 for males and 50 to 57 g day-1 for females. Goats consumed significantly (P < 0.01) more washed S. bigelovii biomass than either rhodesgrass or unwashed S. bigelovii/rhodesgrass mixture. They also required significantly (P < 0.05) more feed per unit of weight pin on that treatment which was attributed to the lowered protein content and partial loss of cell solubles of washed S. bigelovii biomass. Differences, in water consumption among treatments were non-significant. It was concluded that S. bigelovii biomass is an acceptable substitute for rhodesgrass in coastal arid zones where fresh water for forage production is limited but where saline water resources can be exploited.
