Spring and summer, especially in the late spring and early summer, is the season when the forage grasses and blues alternate. During this period, if grass and hay are used improperly, they often affect the growth and health of large livestock (cows, horses, donkeys, and quail), and even cause diseases. The feeding methods are now described as follows: Layered fresh grasses are used in the early spring but the young grasses are young. Grass should not be fed directly to animals during this period. First, chopped green grass into the basket, put the chopped hay in the trough, and sprinkled with a little grass on top to induce the animals to feed dry fodder. Eat a layer and sprinkle them one by one until they are fully fed. Dry and blue chopped mixed feeding As the weather gradually warms up, the number of grasses gradually increases, hay and grass can be chopped individually, and then mixed evenly. The number of grasses started can account for one-third, gradually increasing the number of grass, reducing the amount of hay, until the main grass. But hay is not without it. It is in the exuberant summer and autumn seasons that grasses are mixed with high quality hay. In this way, one can avoid the mouth licking of livestock and prevent it from being greedy; second, it can prevent the forage of livestock from picking forage so as to avoid wastage; the third is to combine the dry and wet forage with a combination of warm and cool, which can not only prevent livestock Cool diarrhea, but also help digestion and absorption of gastrointestinal grass and the use of grass, so that animals increase fast, less sick.
