Green fodder has comprehensive nutrition, good palatability, easy digestion, wide source and low cost. It is one of the important feeds for raising livestock. Feeding livestock with green fodder is especially suitable for rural family farmers, which is simple and easy to operate, and is small and profitable. Therefore, several methods for feeding livestock with green fodder and the problems to be noted are as follows:
First, the method of feeding green fodder,
1. Raw vegetables and grasses can be fed to livestock as long as they are clean and free of sediment. If there is a lot of mud, it must be washed, crushed or beaten. It is also possible to feed the long grass and the whole vegetable directly, but it is not allowed to be fed on the ground to avoid being contaminated by the excrement or being trampled by the mud hoof to cause waste of the feed. Feeding green fodder, it is best to feed now, so as not to cause rotting and causing livestock poisoning. However, the feeding of green fodder may cause the livestock to be infected with parasitic diseases, so the livestock that feed the green fodder should be regularly dewormed. Some green feeds, such as thorny vegetables with steel wool, have poor palatability, which will affect the feeding of livestock and poultry, and should not be fed.
2. Cooked and fed green feed with water, it is a common method of feeding livestock in rural areas. The advantage is that it can kill the parasites or eggs attached to the green fodder, and it is suitable for blending with the concentrate, which is good in palatability. But most of the nutrition has been lost. Therefore, green fodder generally does not promote cooked. The cooked method is only applicable to beans, bean curd, pumpkin, potatoes or vegetables with steel wool. It can destroy harmful substances such as anti-trypsin in bean feed, and can improve the palatability and undesirable substances of pumpkin and potatoes. When cooking, use a large fire, stir well, do not cover the lid, it is best to add some vinegar to promote the evaporation of harmful substances. To be cooked now, do not feed the overnight food, so as not to cause nitrite poisoning.
3. Fermentation feeding Feeding livestock after fermenting green feed is an effective method to improve the palatability and nutritional value of feed. Generally, weeds, wild vegetables, leaves, leaves and stems are washed and chopped, placed in a pool or a cylinder, laminated, and covered with straw curtains, covered with straw, pressed to the green feed. After that, fill it with water to isolate the feed from the air, and then feed the pig after one day of fermentation. If mixed with bran, the effect is better, which can remove the odor and increase the palatability, but it can not be stored for a long time. When the feed becomes sour, it can be washed with water and then fed. If it is too acidic, it can not be fed to pregnant animals to prevent miscarriage.
4. Blister feeding is suitable for some feeds that are not loved by livestock. For example, the leaves of poplar, willow, eucalyptus, apricot, medlar, etc., which have a lot of tannins or tannins, can be removed from the water and can remove the astringency and other strange flavors. Livestock loves to eat.
5. Silage feeds silage, vegetables, leaves, etc. can be stored for a long time. If you can add 0.5%-1% urea during silage, it can increase the protein content of livestock. After silage, the green fodder can soften the grass, improve the quality of the silage, and have the acidity and aroma. It can enhance the appetite of the livestock and increase the feed intake. The nutrients of the green fodder are not easily destroyed. Note that pregnant animals should not be fed more to avoid miscarriage; single feeding is not complete, should be fed with other feeds to balance nutrition; do not mix rotten grass and rotten vegetables during silage to avoid poisoning.
6. Drying and feeding The grass harvested before the knot is dried or dried, which is the best forage for the wintering of livestock. High-quality hay can be used instead of concentrate, and the nutritional value of 2 kg of hay is determined to be equivalent to 1 kg of concentrate. Drying the grass is the easiest way to preserve it. The method is to spread the fresh grass on the ground and use the tweezers to flip it 1 or 2 times a day. After 1 to 2 days, it can be dried, and it can be protected from the rain and rain. Good hay with aroma. The dried grass can also be fed as grass powder.
Second, the use of green fodder to feed livestock should pay attention to the problem
1. Harvest at the right time. In the younger stage, the protein, minerals and vitamins are higher, the crude fiber is less, and it is easy to be digested. The green fodder in this period is most suitable for feeding livestock.
2. The green feed should be kept fresh and clean to prevent mold and mildew. It should be noted that the green feed that has just sprayed the pesticide cannot feed the livestock.
3. Fresh feed should be freshly fed, it is best not to cook it. Cooking materials can destroy nutrients in green fodder, such as vitamins, and nitrite poisoning can occur if improperly prepared. The green fodder suitable for cooking is only a small part, such as: beans, bean curd, pumpkin, potatoes or green vegetables with steel wool. Therefore, green fodder is best fed after chopping, beating, fermenting or silage.
4. Properly match other feeds. According to the different growth stages of livestock, to ensure the needs of livestock for a variety of nutrients.
