Biogas slurry is rich in protein, minerals and amino acids and vitamins necessary for pig growth. Feeding pigs with biogas slurry can speed pig growth and increase pig economic efficiency. However, the use of biogas slurry should take fresh and clean biogas slurry from the biogas digester after 40 days of normal gas production. After gauze filtering, feed it evenly into pig feed. When the start of the addition of biogas slurry, it is necessary to "tune" the pig, that is, to put the bowl containing the biogas slurry into the pigsty, and let the pig adapt to the smell of the biogas slurry. After 10 to 15 days, mix a small amount of fresh biogas slurry. Feed into pig feed. After 3 to 5 days of feeding, the pig will slowly adapt. Addition amount of biogas slurry: Pig stage (body weight 20-25 kg), fed 4 times a day, 0.3 kg each time; shelf pigs (body weight 25-50 kg), fed 3 times a day, 0.6 kg each time; fattening Pigs (50 to 100 kg body weight) were fed 4 times a day, each feeding 1 kg. Pigs fed with biogas slurry need to pay attention to the following matters: First, pay attention to the feed intake of the pigs, to eat or slightly surplus as appropriate. Second, biogas slurry must be taken from the biogas digester 40 days after the normal gas production to feed the pigs. The pH of the biogas slurry is preferably 6.8 to 7.2. Third, can not be followed with feeding, especially in the case of large concentrations of biogas slurry. After the biogas slurry is taken out, it should be left to stand for 1 to 2 hours (1 hour in the summer and 2 hours in the winter) to allow the ammonia to evaporate and feed again. After feeding the pigs with biogas slurry, if the pigs are diarrhea, it means that the biogas slurry is excessive or the pig's digestive system is not adapted, and should be reduced or stopped for 1 to 2 days before feeding. 4. Do not feed biogas slurry to sub-pigs weighing less than 20 kilograms. Sows can't be fed after the estrus and can be fed after delivery. 5. When feeding biogas slurry, the amount of feed for the pig's concentrate can not be reduced.
