During the winter and early spring seasons, there is a lack of green feed, and the countryside generally uses hay and crop straw to feed livestock. In order to increase the use value of feed, you should grasp the following points when processing and feeding:
1. Try to eat hay and straw with more leaves. Some of the leaf nutrient content is more than the stem. Therefore, care should be taken in processing the modulation so that the blades are not lost or discarded. Leguminous plants and sweet potato vines are the most vulnerable to leaf loss. They should be taken care of and preserved, and allow livestock to eat hay and straw with more leaves.
Second, rough feed should be properly matched with fine material. Roughage, especially straw and oyster shell, has low net energy content and large volume. As a basic feed for growing, fattening, labor, milk production and other livestock, it should be used together with a small volume and high net energy content concentrate. However, roughage is indispensable as a feed for winter and early spring maintenance.
Third, to be fed with legume stalks. Single gramineous straw, such as straw, wheat straw, and other crude protein, calcium, phosphorus, etc., can not maintain the nutritional needs of livestock, should be fed with protein and calcium content of more legume stalks to improve the feed Utilization rate. In particular, do not feed the livestock with a single wheat straw for a long period of time, because a single wheat straw can easily cause ruminal livestock (cattle and sheep) to suffer from ruminal palsy, and monogastric livestock (horses, baboons, and donkeys) suffer from chronic dyspepsia.
Fourth, the correct use of various parts of the straw. The coarse part of the lower part of the straw should be cut off and used as fuel when feeding. The top of the straw can be cut into 3 cm long and the cattle can be cut into 1.5 cm to feed the sheep. When the pig is fed, the grinder should be used to crush it first. When feeding livestock, you can put the clams in the pan and fry yellow, and then crush and feed them. Large animals cannot be crushed.
Fifth, take a variety of forms of processing methods. In order to improve the digestibility and adaptability of straw feeds, it is possible to adopt physicochemical and biological methods such as spraying salt water, fermentation, alkalization, etc., and at the same time, add some chopped sweet potatoes or carrots to make the animals eat sweet and eat more. Love to eat. In this way, livestock can not only be fast, but also can prevent rickets and other diseases.
