Matters needing attention in feeding cattle with grass in summer

In summer, green forage grass grows vigorously and has various kinds. They are not only green in color, fresh and juicy, easy to digest, but also rich in protein, amino acids, vitamins and minerals. They are ideal high-quality feeds for fattening beef cattle and cattle. However, although green feed is good, in the process of using it to raise cattle, if it is not properly used, problems will also occur. Three problems that should be paid attention to when feeding cattle with green feed are introduced as follows:

I. Note that green feed cannot be single. Green feed is an indispensable quality feed for fattening beef cattle, but it contains too much water and less dry matter. If only green feed is used to feed beef cattle (especially beef cattle in the later fattening period), although it is full, the dry matter energy absorbed by its body cannot meet the needs of long meat and fat deposition. Therefore, when fattening beef cattle with green feed, it is necessary to supplement and incorporate appropriate amounts of dry grass, grain feed (corn, sorghum, etc.) and protein feed (bean cake, peanut cake, etc.), so that the fattening effect can be more significant.

Second, pay attention to nitrite and hydrocyanic acid poisoning. When feeding beef cattle and cattle with green and juicy feed, one is not to use vegetable leaf feed (such as radish leaves, cabbage leaves, etc.) that has been accumulated for too long, because they contain nitrate, which can be reduced to nitrite by spoilage bacteria, and cattle will be poisoned after eating; Second, do not feed corn seedlings, sorghum seedlings, flax leaves, because they contain cyanide glycosides, and cattle will be poisoned by hydrocyanic acid in the rumen after eating.

Third, pay attention to young legume grass do not feed too much. Because leguminous forage protein quality is good, rich in vitamins and trace elements, palatability is good, especially in the tender stage, they contain saponin, cattle eat too much, produce a lot of foam in their rumen, easy to make cattle rumen swelling disease.
