1. Pay attention to the herbicide poisoning of pastures when spraying pesticides. It is necessary to know in detail the spraying time of the grassland. Forage grass that has just sprayed pesticides cannot be used as feed, and it will be used after raining or after 1 month. In order to prevent pesticide poisoning.
2. Pay attention to poisonous poisoning Poisonous common poisonous grass has poisonous parsley, noisy sheep and so on.
3. Germinated potato, sorghum seedlings, corn (2354, -1.00, -0.04%) seedlings can not feed the pig potato germ contains a lot of solanine, which will lead to poisonous paralysis in pigs; pigs eat fresh sorghum tender seedlings, corn Miao, will be caused by hydrogen cyanide poisoning due to more hydrogen cyanate.
4. To harvest forage in the best nutrition period, feed the grass with grasses should be harvested before the crop heading, legumes should be harvested before flowering, leafy forage should be harvested in the leaf stage; Vitamins and other nutrients are the highest.
5. Forage grass can not be stored for a long time. Feeding green and green feed in summer and autumn, it is best to feed while feeding. The greenish feed will heat up and become rot, and a large amount of nitrite will be formed under the action of bacteria. Pigs will easily lead to poisoning after eating.
6. Can not feed a forage for a long time. Feeding pigs with green-green feed has many advantages, but the forage varieties have different nutritional characteristics. Gramineous forages are rich in carbohydrates, legumes are rich in protein, and leafy forages are rich. Containing vitamins, minerals, etc., long-term feeding alone a pasture is easy to cause nutritional insufficiency. Therefore, these types of pastures should be properly mixed and fed. If they can be matched with wild weeds, leaves, aquatic plants, etc., the effect will be better. At the same time, when feeding pigs, it should be matched with a certain proportion of corn, bran, bean cake and other concentrates, supplemented with appropriate amount of bone meal, eggshell powder, trace elements and other mineral feed.
7. After feeding the green feed , return it to a small section of 0.5~1 cm long or beat, then pour the mixed feed directly to the pig; for the greenish feed with poor palatability or coarse fiber, it is best to ferment and then feed; At the same time, the first feeding should be carried out, the first dose is about 20%, from less to more, usually 3 to 5 days of training, can be fed in sufficient quantities.
8. The feeding amount should not be too large. The green-green feed should not be over-supplied, especially for small pigs. When feeding the green-green feed with large moisture, it must be limited. Prevent overfeeding from causing diarrhea.
