When pesticides are sprayed on weeds and weeds are harvested, we must learn more about the spraying time of the grass. After pesticides are sprayed, they cannot be used as fodder. Wait until it rains or reappropriates it after another month to prevent pesticide poisoning. .
The two poisonous grass poisoning common poisonous grasses are poisonous celery and lively sheep. The poisonous celery is also called wild celery. It is a perennial plant of the Umbelliferae family. Its roots and stems contain the alkaloid "toxic parsley"; the yangyanghua, also known as the yellow flower grass, the yellow azalea, the Yingshan yellow, grows on the hillside, the stone seam and The bushes contain toxic ingredients of azaleas in their leaves and flowers.
Germinated potatoes, sorghum and young shoots, and corn seedlings cannot be fed to pigs. Potato germs contain large amounts of solanine, which can lead to toxic numbness in pigs. Pigs who eat fresh sorghum and young shoots and corn seedlings will have more hydrocyanic acid glucosides. Lead to hydrocyanic acid poisoning.
Feeding pigs for harvesting at the best trophic stage should be harvested before heading, legumes should be harvested before flowering, and leafy grasses should be harvested at leaf clusters. At this time, protein, vitamins and other nutrients have the highest levels.
Can not be stored for too long. Summer and autumn feeding green feed, it is best to feed while side-feeding, green feed long heap heat or become rot, in the role of bacteria, will generate a lot of nitrite, pigs easily lead to poisoning after eating.
Can not long-term single feeding green feed Although feeding pigs have many advantages, but different pasture varieties have different nutritional characteristics, gramineous grasses are rich in carbohydrates, legume grasses are rich in protein, leafy grasses are rich in vitamins, minerals, etc. If long-term feeding alone can lead to incomplete nutrition. Therefore, these pastures should be properly matched and fed. If we can combine wild weeds, leaves, and aquatic plants, the effect will be better. At the same time, when feeding pigs, a certain proportion of corn, bran, bean cake and other concentrated feeds should be added to supplement the amount of bone meal, eggshell powder, trace elements and other mineral feeds.
The correct feeding method is: After the green food is collected, it is cut into small pieces of 0.5cm to 1cm in length or beaten, and then mixed into the mixed feed to feed the pig directly; after the fermentation of the green feed with poor palatability or crude fiber content is best, Feeding again; at the same time when the initial feeding should be training feeding, the first blending amount of about 20%, from less to more, usually after 3 days to 5 days training feeding, can be fed in sufficient quantities.
The amount of feed should not be too large. Green feed should not be used to feed pigs, especially piglets. When feeding large amounts of green and green feed, it must be limited to prevent overfeeding causing diarrhoea. Forage ratio: 0.3:1 for piglets, 0.5:1 for medium pigs and 1 to 2:1 for pigs. The fermented blue stocks have a savory sour taste, yellow-green color, and slightly soft texture. The amount of piglets fed is 0.05kg to 0.2kg per day, 1kg to 1.5kg per day for boars, 0.5kg to 1kg per day for pigs, and 2kg to 2.5kg per day for sows.
