Fermentation of corn stalk instead of pasture can increase the milk production of dairy cows

In the United States, corn is abundant. In recent years, research on the use of corn stalks instead of green forage grass has been active. Among them, the method of feeding corn stalks to raise dairy cows and increase milk production of milk has been successful. One of the methods is to crush the silage corn stalks and mash them into conventional feeds at a rate of 40%. The amount of milk produced is about 15% higher than that of single feeds. Another method is to mix corn stalks and sunflower stalks in a silage by 6:4, and then mix the mash with 40% of the mixture into regular shake and feed. The milk yield can also be increased by 10% - 12%. After testing, the content of crude protein in corn stalk silage reached 11.5%, fat content was 8.5%, and acid crude fiber was 34.5%, which was higher than that of other pure green fodder or pasture, which was more conducive to stimulating milk production.
