The purpose of this project was to produce complete feed blocks using common forage sources in the Sistan region. The treatments involved different ratios of concentrate to forage, with a ratio of 30:70. The binding agent varied among the treatments. Treatment 1 consisted of 10% molasses, treatment 2 included 10% molasses and 4% bentonite, treatment 3 contained 4% bentonite, 5% wheat flour, and 5% barley flour, treatment 4 had 4% bentonite and 10% wheat flour, treatment 5 included 4% bentonite and 10% barley flour, and treatment 6 consisted of 10% barley flour and 5% wheat flour. The proportions of common reed, sorghum, alhagi, and straw were 10%, 10%, 5%, and 5% respectively, totaling 30%. To assess the strength of the feed blocks, a durability test was conducted. The blocks were thrown from a height of 1.8 meters, and the ratio of the weight of the largest remaining piece to the initial weight was used as a measure of durability. Treatment 2 exhibited the highest durability at 56.03%, while treatment 6 had the lowest durability at 42.75% (P < 0.05). There were no significant differences observed between treatments in terms of post-compression expansion and density at different time points after block construction. The most significant changes in volume and density occurred within the first 24 hours. Additionally, except for treatment 6, no signs of mold growth were observed in the other treatments until the fifth week. A level of 10% molasses or 4% bentonite can create satisfactory adhesion in the blocks. |
