Can Alhaji maurorum as a halophyte plant be ensiled with molasses and Saccharomyces cerevisiae well?

Alhagi maurorum (Caspian Manna, AM) is a species of legume found commonly in the semi-arid region of the world. Nutritional aspects of silage prepared from AM have not been scientifically investigated so far, therefore, in this study, chemical-mineral composition, gas production parameters, ruminal fermentation parameters, buffering capacity, and silage characteristics of AM were investigated by standard laboratory methods. Fresh AM was ensiled in the mini-silos (3.5 kg) and treated with (1) no additive (control), (2) 5% molasses, (3) 10% molasses, (4) 1 × 104 CFU of Saccharomyces cerevisiae [SC]/g of fresh silage, (5) 1 × 104 CFU of SC/g of fresh silage + 5% molasses, (6) 1 × 104 CFU of SC/g of fresh silage + 10% molasses, (7) 1 × 108 CFU of SC/g of fresh silage, (8) 1 × 108 CFU of SC/g of fresh silage + 5% molasses, and (9) 1 × 108 CFU of SC/g of fresh silage + 10% molasses for 60 days. The lowest concentrations of NDF and ADF were related to treatments no. 6 and 5, respectively (p < 0.0001). The ash content as well as sodium, calcium, potassium, phosphorus and magnesium were highest in treatment no 2. Silages containing 10% molasses (no. 3) had the highest and lowest lactic (p < 0.0001) and butyric (p < 0.0001) acids, respectively. The highest amount of potential gas production was observed in treatments no. 5 and 6, respectively (p < 0.0001). Total yeast was decreased with increasing molasses in the silages (p < 0.0001). Acid-base buffering capacity was also highest in treatments no. 6 and 5, respectively (p = 0.0003). In general, due to the fibrous nature of AM, it is recommended to add molasses at levels of 5 or 10% when ensiling. The silages containing SC at a lower level (1 × 104 CFU) along with higher levels of molasses (10% of DM) had better ruminal digestion-fermentation characteristics compared to other silages. Also, the addition of molasses improved the internal fermentation characteristics of AM in the silo.
