Sudan grass plant is tall, strong regeneration, high grass yield, suitable for modulation of hay, can also be used for summer green fodder, but also can be adjusted to make high-quality silage. It can also be used for summer fodder, and can also be adjusted to make high-quality silage. Cattle, horses, sheep and pigs are all edible. Sudan grass is also one of the high quality green fodder for pond fish. According to the analysis, it contains rich digestible nutrients and rich essential amino acids.

Nutritional composition and essential amino acid content of Sudan grass (%)

Its nutrient content varies greatly with climate, soil conditions and fertilization status, mowing period and modulation methods; the digestibility of protein in the silage period reaches 44%, the digestibility of crude fat is 57%, and the digestibility of crude cellulose is 64%, which is a kind of high-quality forage crop.

From the table, it can be seen that the crude protein content in the dry matter of sudangrass at the spike stage is higher in annual cereal crops such as oats, sorghum, corn, etc., and the crude fiber content is lower. Because of the higher yield than other forage grasses, the sudangrass has an absolute advantage when calculating the feed value per unit area. This is as the Russian academician Mosolov said, "The protein content of sudangrass hay is the highest among the grass forages." The digestibility of sudangrass is relatively high, with 61% of crude protein digestibility, 58% of crude fat, 69% of crude fiber, and 73% of nitrogen-free leachate at the tassel stage. In terms of forage evaluation, Sudan grass is among the good forage grasses, which is popular among the public in agricultural and pastoral areas. It is also rich in carotene and has the highest tillering stage.

Nutritional composition and essential amino acid content (%)

Sudangrass contains a small amount of hydrocyanic acid in the seedling stage, and it is important to prevent hydrocyanic acid poisoning when feeding livestock. However, as the plant grows, its content decreases and there is generally no danger of poisoning.
