Thirty six Arabian male lambs with an average age of 4.5±0.2 month and 25.3±1.13 kg live weight were fed by experimental diets for 80 days. The experimental diets included 1- Control, 2- 15% Suaeda, 3- 15% Halocnemum, and 4- 30% mixture of Suaeda and Halocnemum. Treatments had no significant effects on daily weight gain, feed conversion ratio and final body weight. Water intake increased by consumption of halophytes (p < 0.001) compared to the control group. Crude fat and ADF digestibility were higher in control and 15% Suaeda treatments compared to other treatments (P=0.003). Organic matter digestibility was higher in 15% Suaeda and 15% Halocnemum treatments compared to other treatments. Blood urea nitrogen of lambs fed by 30% mixture of Suaeda and Halocnemum was lower than other treatments (P=0.0001). Lambs fed 30% saline plants had less total deposit carcass fat (P=0.024) and more meat content (P=0.006). Muscle yellowness increased in lambs fed halophytes compared to the control treatment (p < 0.001). The results of this study showed that replacement of wheat straw and alfalfa hay with Halocnemum and Suaeda, in high concentrate diets could maintain fattening performance and reduce carcass deposition of fat.
