Silage corn quality standards go beyond sugar content: these factors are also measures

At present, with a large surplus of feed corn in our country, the slogan of national grain destocking has also been repeated for several years. Reducing corn acreage is already imperative, while silage corn is increasingly being taken seriously and is being continuously promoted in many regions. In agricultural production, high-quality silage corn is also favored by farmers and livestock raisers, so what counts as high quality? Let us introduce it below.

As for the quality of silage corn, it involves many aspects. No matter what product it is, a single indicator cannot measure its quality, and the same is true for silage corn. Fat content, starch content, protein content, vitamin content and so on are all key indicators for measuring the quality of silage corn.

Many buyers focus on sugar content when purchasing silage corn. In fact, caring only about the single indicator of sugar content cannot judge the quality of silage corn. It is just like evaluating a person's academic performance: defining whether their performance is good or bad based on a single subject is obviously not feasible.

Sugar can be converted into sucrose and starch for storage, and both can also be converted into sucrose. This is the sugar metabolism cycle process in organisms. If the starch content of corn is very high while the glucose content is very low, does that mean its quality is low? Obviously not, because even for us humans, whether we eat steamed buns or rice, the largest amount of substance we intake every day is still starch. And starch will likewise be converted into glucose, and it can also provide nutrition.

As far as starch alone is concerned, the content in generally high-quality silage corn is around 20%, while even higher-quality silage corn reaches a content of more than 30%, and the sugar converted after such silage corn is eaten by animals will naturally not be low either.

There are also the fat and protein contents of silage corn, which are likewise key indicators for measuring its quality. From the perspective of feed, high protein content is also more favored by the market and livestock raisers, and can provide animals with more protein requirements.

In addition to the edible quality aspects mentioned above, there are also some cultivation-related quality aspects, such as resistance to pests and diseases, and yield indicators are also aspects that need to be examined. Even if the edible quality is very good, if the ability to resist pests and diseases during cultivation is very weak and the yield is also very low, then what meaning does all this have?

In summary, the method of judging quality solely by sugar content is not advisable.
