Core Tip: Entering the summer, there are many grasses and green vegetables, good growth, full variety and large quantity, which is a good feed for feeding livestock. However, in summer, it is hot and rainy. Green feed is often prone to mildew due to excessive harvesting, storage and modulation, and often leads to nutrient loss and feed waste. Therefore, we must master the use of green feed.
1, raw feed
Green 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 poisoning of livestock and poultry. 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
Feeding the green fodder with water is a common method of feeding pigs 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 concentrates. The palatability is good, 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, fermented to feed
Feeding livestock after fermenting green fodder is an effective way 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 pigs to prevent miscarriage.
4, blisters feed
It is suitable for some feeds that are not loved by livestock. For example, the leaves of poplar, willow, eucalyptus, apricot, and medlar, which have a lot of tannins, can be removed from the water, so that the smell of animals and other strange smells can be removed. have eaten.
5, silage feed
The grass, 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 cattle and sheep. After silage, the green fodder can soften the grass, improve the silage quality, and have a sour taste. It can enhance the appetite of cattle and sheep, increase the feed intake, and the nutrient content of the green feed is 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
Drying or drying the grass harvested before the knot 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 turn it 1-2 times a day. It can be dried in 1-2 days, and it can be protected from the rain and rain. Good hay with aroma. The dried grass can also be fed as grass powder.
