Matters needing attention in feeding new corn to sheep

When it comes to the season of new corn harvest, due to the shortage and high price of old corn in the market, many sheep farms begin to use a large number of low-priced new corn, and some sheep farms even replace them all with new corn. Combined with a visit to the front-line sheep farm, it is found that feeding new corn is easy to cause sheep diarrhea, high feed intake and slow growth.

Characteristics of new corn:

1. When new corn comes down, it takes a month of post-ripening, that is, the process of starch transformation.

If the conversion is not completed, there is not enough energy.

two。 New corn is rich in water and easy to mildew.

Mycotoxin, a derivative of mold, can destroy the body's immune system and greatly reduce the body's disease resistance.

There are three hazards of new corn:

1. The moisture content is high and unstable.

two。 The ripening lag of new corn is easy to cause diarrhea. Old corn does not do this harm (but old corn also pays attention to mildew).

3. The harm of mold.

4. Pay attention to the difference between mold and mycotoxin harm.

5. The harm of toxin and mold in new corn is greater than that in old corn.

How to use it scientifically to maximize the nutritional role of new corn?

1. Partial use: mix old corn with some new corn, gradually increase the proportion of new corn, transition for half a month, in order to reduce the effect of resistant starch. The feed of new corn is high in moisture and content, so it should not be stored for a long time, it is best to feed it with it.

two。 Screening wind selection: screening and wind screening of new corn can effectively reduce the content of broken grains and impurities in corn, thus reducing the harm of mycotoxins to animals, and palatability can also be improved.

3. Moderate aging: new corn needs to be stored in storage for 5-6 weeks, and then used after ripening.
