Many people don't know what silage is? Mix storage and storage. Every year at this time of the year, there will be a high price on the Internet to buy wheat seedlings, and some articles even buy wheat straw, which is ill-intentioned social capital speculation food, these capitals have been successful in the field of garlic, ginger, and green onions in the past, and once very cheap vegetables were hyped into high prices, and profits have increased significantly, and now they are entering the grain again, and the speculation for several years has not been successful, why oppose harvesting wheat to make green reserves?
One is that the yield of wheat grass is low, and it can only be harvested once, if the harvest loss is very large when it is young, the grass yield and nutritional value are much worse than perennial ryegrass or even oat grass.
Second, there is no farm to buy a large number of wheat seedlings to make silage, the annual data are old data, such a high price to buy wheat straw, the farm is to calculate the cost of breeding, there is a problem with the brain to use the price higher than the price of wheat grains to purchase wheat straw, after the wheat harvest, the treatment of wheat straw has become a headache for grain people, the farm can only consider the purchase of wheat grains and not the purchase of low nutritional value of immature wheat and wheat straw at a high price.
Third, wheat is the main food of human beings, and wheat is a fine grain, wheat only processing by-product wheat bran as livestock and poultry feed, flour is the main ration of human beings, wheat has not been classified as livestock and poultry feed in history, in order to ensure the supply of human rations, all countries in the world are opposed to harvesting wheat for green storage.
Fourth, what is silage? Silage is a kind of juicy and shelf-stable made by filling fresh green fodder into a closed silage cellar or plastic film bag through microbial fermentation, which can supply feed for the whole year. Silage is stored with crop straw to supply cattle and sheep with year-round feed, not grain. The mainland has used silage to feed ruminant cattle and sheep for more than half a century, and the use of silage can effectively use local green fodder, which has twice the effect on the development of grass-fed livestock. The raw materials for silage production have been specially planted silage corn, sorghum, rye grass to the use of corn cob corn stalks, the use of silage to raise livestock, the profits of cattle and sheep are further improved, feed accounts for about 70% of the breeding cost, make full use of corn straw to make silage, greatly reduce the cost of feed, and promote the development of captive cattle and sheep.
Wheat is the third largest food crop in the continent after rice and corn, and the amount of wheat straw is also the largest among wheat straws. According to research, the digestibility of dry matter of wheat straw is 45-51%, and the crude protein content is 2.54%, which is lower than that of other crop straw. High crude fiber content, low crude protein, low moisture, large volume, hard texture, poor palatability, and low feed intake of livestock limit wheat straw to be fed directly to cattle and sheep.
Wheat straw is different from corn straw, corn straw can be harvested when corn is mature and some leaves are green, corn straw at this time contains sufficient water, it is better to make silage. Wheat straw can only be harvested when the wheat is fully mature, and at this time the wheat straw is already dry and cannot be used to make silage. Cattle and sheep without treatment of wheat straw are not eaten, and can be used as cattle and sheep feed after processing, and can be treated with ammonia or alkalization, which can improve digestibility and feed intake. Due to the large volume of wheat straw, it can be crushed and made into pellet feed for cattle and sheep.
