معرفی گیاه مالوفرا کروسئا برای الگوی کشت مقاوم به اقلیم های خشک و شور جهت استفاده در علوفه دامی

In this research, a type of low-water and halophyte plants common in South Khorasan province named Naz Malofra was investigated. The purpose of this research was to evaluate the use of low water consuming plants and halophyte as a forage source of ruminants (in vitro). After collecting these plants from Birjand urban green area , its chemical composition was determined using a standard laboratory method, and then the dry and ensiled samples with sugar beet pulp were tested for gas production and degradability of dry matter. The results of the chemical analysis of Naz Malofra plant showed that the percentage of crude protein, insoluble fiber in neutral detergent, insoluble fiber in acidic detergent, crude fat, ash, total phenolic compounds and total tannin were 8.58, 13.1, 4.65, respectively. It was 2/02, 10/52, 10/58 and 1/27. . The results of the gas production test showed that the gas production rate was higher in Naz mellifera plant and had a significant difference compared to dry alfalfa. The results of degradability of dry matter at zero, 2, 4, 8, 12, 16, 24, 48 and 72 hours using two cows with rumen fistula showed fast decomposition (a), slow decomposition (b) and rate constant. The decomposition (c) of Naz Malofra plant was 19.82, 65.83 and 0.089, respectively
