using halocnemum strobilaceum, prosopis juliflora, and alfa-alfa silage for providing forage of livestock in arid areas

in this study a new and valuable forage source was introduced with combination and silage of alfa alfa halocnemum and mesquite via chemical gas production and in vivo methods. to perform this research first the right amounts of the species were collected. then they were cut by chopper to the dimensions of less than 5 cm. then halocnemum mesquite fruit alfalfa and molasses were silaged according to dry matter weight in 4 treatments with three replications in a rcbd. these treatments include: 50h 10k 30u 10m 50h 20k 20u 10m 50h 30k 10u 10m 30h 30k 30u 10m. at the end of experiment (28 d) the amounts of silage qualitative factors were measured using standard methods suggested by aoac. 3 ghashghaee yearlong sheep (45+2.5 kg) and 3 toodeh siah yearlong goats(30 +2.5 kg) used in a split plot scheme with 3 replications for estimation of silage consumption. according to the results 50h 20k 20u 10m and 50h 10k 30u 10m treatments have the most digestibility at 12 hours of incubation. study of silage nutritional value by gas production methods indicated that 50h 20k 20u 10m treatment has the greatest amount of dom omd. dmd and me were consumed more by the livestock. therefore we can recommend it as an appropriate combination with economic and feeding benefits
