The problems that should be paid attention to when raising cattle and feeding whole-plant silage corn
In recent years, more and more farmers have fed whole-plant corn silage to dairy cows. The rational use of whole-plant corn silage has brought considerable economic benefits to dairy farmers. However, due to the lack of experience of some dairy farmers, they do not have a comprehensive and systematic understanding of the nature of whole-plant silage corn. Feeding this kind of roughage with high water content and high acidity will cause metabolic disease, acidosis and true stomach displacement of dairy cows The increase in the number of dairy cows has caused some dairy cows to abort and premature, and also brought some undue losses to dairy farmers.
The whole plant silage corn is rich in sugar, crude protein and vitamins, making it a good roughage for dairy cows. But its crude fiber and mineral content are insufficient. In particular, the lack of crude fiber dry matter, high acidity and easy fermentation are its weaknesses. When using it, we should make full use of its advantages to avoid its own deficiencies to bring harm to farmers, and hay (grass) Leymus chinensis can supplement its deficiencies. It is recommended that dairy farmers add some hay or Leymus chinensis when feeding whole-plant silage corn, so that the benefits of whole-plant silage corn can be fully utilized, and the possible harm to the dairy cows due to its own deficiency can be avoided. Raise healthy and productive cows.
Diets added to cows cannot be soaked in water. Coarse fodder (silage + hay + legume forage mixed evenly), and concentrated dry powder are put into the tank for feeding. There is enough clean tap water in the sink to allow the cows to drink freely.
Some dairy farmers also add bean dregs, starch residues, and beer lees when feeding whole silage corn. In these roughages, the amount of hay fed should be increased, so as to meet the needs of cows for crude fiber, otherwise the cows will still produce questionable.
A small amount of hay should be in the roughage fed to calves after weaning. For grown-up cattle from 6 months to 24 months, there should be 1 kg to 2 kg of hay in the diet. It is best to feed dairy cows with 3 The combination of planted forages is conducive to the growth of the cattle and the cultivation of high-quality reserve cattle with large body and high milk production.
