Embodiment Construction

[0008] When using biogas slurry to feed pigs, it is generally divided into three stages: piglet stage (weight within 25kg), 4 times a day, each pig is fed biogas slurry about 0.3kg each time; shelf pig stage (weight 25-50kg), 3-3 times a day 4 times, about 6 kg of biogas slurry each time; for fattening pigs (weight 50-100 kg), 3 times a day, about 1 kg of biogas slurry each time.

Abstract

The invention discloses a pig feed additive, which is characterized in that the biogas slurry after complete fermentation is left for 0.4 to 0.6 hours to volatilize ammonia so as to obtain the feed additive. The pig feed additive has the advantages that the pig fed with the biogas slurry as the additive is edacious and drowsy, and has little active amount and good coat color; feed is saved; feed utilization ratio is improved; compared with the pig without feeding the biogas slurry, the pig fed with the biogas slurry can gain weight by 0.15 kg a day on average; the marketing time is advanced by 40 days; and pig appetite can be stimulated and pig digestion and absorption function can be strengthened due to a large amount of active enzymes and organic acids existing in the biogas slurry.

Description

technical field [0001] The present invention relates to livestock feed additives. Background technique [0002] At present, biogas technology is vigorously promoted in rural areas. As a by-product of biogas production, biogas slurry is generally used as fertilizer and applied to farmland, and some is wasted as sewage, which causes both waste and pollution. Since the biogas slurry can produce a large amount of active enzymes and organic acids after fermentation, it has a catalytic effect on the growth of pigs. At present, there is no use of biogas slurry as a pig feed additive. Contents of the invention [0003] The purpose of the invention is to use the biogas slurry as a pig feed additive to improve the utilization efficiency of the biogas slurry. [0004] The technical scheme adopted by the present invention is: after taking out the fully fermented biogas slurry from the water pressure chamber of the biogas tank, let the ammonia volatilize for about 0.4-0.6 hours, then...
