Abstract
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.
