Green feed is one of the important feeds for raising livestock, with its comprehensive nutrition, good palatability, easy digestion, wide source, and low cost. The use of green fodder to feed livestock is particularly suitable for rural households. It is simple and cost-effective. Therefore, several methods for feeding green animals and issues that need attention are described below:
First, the method of feeding green livestock
1. Raw vegetables and green grass can be fed to livestock as long as they are clean and free of sediment. If there is a lot of silt, it must be washed and crushed or beaten. It is also possible to directly feed longgrass and whole vegetables, but it is not possible to feed them on the ground so as not to be contaminated by excrement or to be wasted due to trampling. Feeding green feed, it is best to feed now, so as not to cause rotting animal poisoning. However, the feeding of green feed may cause the livestock to become infected with parasites. Therefore, livestock that feed green feed should be regularly dewormed. Some green fodder such as thorny vines with steel wool, poor palatability, will affect the livestock and poultry feed, should not be fed.
2. Cooked and boiled green fodder boiled and fed, is a commonly used method of feeding livestock in rural areas, the advantage is to be able to kill parasites or eggs attached to green feed, and is suitable for blending concentrate feed, good palatability, But most of the nutrients have been lost. Therefore, green feed generally does not promote ripening. The ripening method is applicable only to beans, bean curd squash, pumpkin, potatoes, or vegetables with strips of steel, etc. It can destroy the anti-trypsin and other harmful substances in the bean feed, and can improve the palatability and undesirable substances of pumpkins and potatoes. When cooking, use a large fire, stir frequently, and do not cover the lid. Add a little vinegar to it to promote the evaporation of harmful substances. If you want to cook now, do not feed overnight food to avoid nitrite poisoning.
3. Fermentation Feeding of green feed after fermentation is an effective way to increase feed palatability and nutritional value. In general, weeds, wild vegetables, leaves, leaves and vines are washed and chopped into a water tank or a cylinder and compacted layer by layer. When eighty percent is filled, they are covered with straws and pressed with stones until the green feed sinks. After that, add fresh water to the animal to isolate the feed from the air. After the fermentation is continued for one day, feed the pigs. If the mixture is fermented with bran, the effect is better. It can both remove the odor and increase the palatability, but it can not exist for a long time. When the feed becomes sour, it can be rinsed with water and then fed. If it is overacid, it cannot feed pregnant animals to prevent miscarriage.
4. Blister feeding applies to feeds that some livestock do not like to eat. If there are strange leaves or leaves containing more than tannins such as poplar, willow, hazel, apricot, etc., they can remove astringency and other strange odors after soaking in water. Animals love to eat.
5. Silage feeding Green grass, vegetables, leaves, etc. Silage, long-term preservation. If 0.5%-1% urea is added during silage, the protein content needed by livestock can be increased. After silage, the silage can soften the grass, improve the quality of the silage, and bring acid and aroma. It can enhance the appetite of the livestock and increase its feed intake. The nutrients of the green feed are not easily destroyed. Attention should not be given to pregnant animals to feed more, so as to avoid abortion; Single feed nutrition is not complete, should be fed with other feed, so that nutritional balance; Silage not mixed with rotten grass, rotten vegetables, so as not to cause poisoning.
6. Drying and drying the grasses that are harvested before the seeds are dried or dried are the best forages for livestock to eat during the winter. High-quality hay can replace the concentrate feed and the nutritional value of 2 kg of hay is determined to be equivalent to 1 kg of concentrate feed. Drying the grass is the easiest way to preserve it. The method is to spread the fresh grass thinly on the ground and turn it 1 or 2 times a day with a rake. After 1 to 2 days, it can be dried. With the sun, it can prevent rain and damp, so as to guarantee the existence of grass. Good smell of hay. Sun dried grass can also be made into grass powder.
Second, pay attention to the problem of feeding livestock with green feed
1. Harvest at the appropriate time. In the young period, the content of protein, minerals and vitamins is higher, crude fiber is less, and it is easily digested. Green fodder in this period is best for feeding livestock.
2. Green feed should be kept fresh and clean to prevent mildew. It should be noted that green feed that has just been sprayed with pesticides cannot feed livestock.
3. Fresh feed for green feed, it is best not to cook and feed. Cooking will destroy nutrients in the green feed, such as vitamins, and nitrite poisoning can occur if improperly prepared. Suitable for mature feed is only a small part of green feed, such as: beans, bean curd residue, pumpkin, potatoes or vegetables with steel hair and so on. So green feed is best chopped, beaten, fermented or siled and fed.
4. With other feeds properly. According to the different growth periods of livestock, in order to ensure the animal's need for multiple nutrition.
