First, chopping and chopping is the simplest and most important method of preparing straw. All kinds of straw and older hay should be chopped before feeding. After shredding, it can not only reduce energy consumption during chewing, but also reduce the waste of feed, and it is easy to use with other feeds to increase feed intake. The degree of straw shredding should depend on the type and age of the livestock. Feeding cows' straws can be slightly longer, usually 3 to 4 centimeters. Horses, baboons and donkeys are 2 to 3 centimeters, sheep are 1.5 to 2.5 centimeters, and old and weak and young animals should be shorter.
Second, the purpose of crushing the straw is to improve the digestibility. The crushed fineness is generally 0.7-1.0 cm. However, it should not be crushed too thinly. If it is too fine, the animal does not chew properly, the saliva cannot be fully mixed, the horse is susceptible to bruising, the cows and sheep are liable to cause rumination stagnation, and the speed of feed through the rumen is accelerated, the rough material residence time in the rumen is shortened, the fermentation is incomplete, and straw digestion is reduced. rate.
Third, the soaking soaking method is to soak the chopped straw with water and mix the fine material and then feed it. This method is commonly used in rural China's straw modulation method. The soaked stalks are softened and the palatability is improved. The fine material is easy to stick in the straw and the straw utilization rate can be improved.
Fourth, grind the green wheat straw on the threshing floor, 30 to 40 cm thick, and then spread 30 to 40 cm of fresh green alfalfa, alfalfa and then covered with a layer of the same thickness of wheat straw, and then with the stone rolling . The alfalfa flattened out of juice and was absorbed by wheat straw. Flattened cockroaches can be dried in 12 to 24 hours on hot days. The advantage is that the hay can be made quickly, the drying speed of the stems and leaves is even, the loss of the leaves is reduced, and the palatability and nutritional value of the wheat straw are increased.
Fifth, cooking and cooking can improve the palatability of straw and soften cellulose. It is commonly used to feed breeders, fattened cows and low-yielding cows. The cooking temperature was 90° C. After 1 hour, it was placed in the box for 2 to 3 hours. In addition, straw can also be modified to feed the cows. The method is to chop the chopped straw with a small amount of bean cake and salt, put it in a large pot and boil it, boil it for 30 seconds, and then remove and feed the cow. Or mix the chopped straw with carrots, place it in a wok (pan under the vent tube, there is a hole in the trachea), cover the sacks, steam from the trachea into the steam for 20 to 30 seconds, after 5 to 6 hours Remove the feed cows, the daily feed equivalent to dry straw 4 ~ 4.5 kg. Good feeding results in increased milk production.
6. Modulation of Straw Pulp Straw pulp prepared from gramineous crops can improve palatability and be easily digested. It is suitable for feeding finishing pigs. In the preparation method, the straw is cut into 2 to 3 cm long, 5 kg of lime powder is added per 100 kg of straw, and water is added to the mixture. After boiling, 6 to 7 kg of water are added and boiled for 1 hour. After removing, rinse with clean water. Put it into a pulper and beat it at a speed of 220 revolutions per minute for 80 seconds.
