Biogas slurry is rich in protein, minerals and amino acids and vitamins necessary for pig growth. Its nutrient composition is comprehensive. It provides a material basis for promoting pig growth and development, increasing appetite, enhancing immunity, accelerating growth, and improving feed utilization. Adding biogas slurry to raise pigs is simple and easy, no cost, so pigs can be slaughtered more than one month in advance. Each pig saves about 60 kg of feed, saves feed and epidemic prevention costs 80-100 yuan, and brings considerable economic benefits to farmers. .
The technical points are as follows:
The biogas slurry is taken from a biogas digester that normally produces gas for more than one month. Take off the floating foam on the surface of the biogas slurry before taking it, take the clear liquid at 40-70 centimeters in the upper layer and filter it with sand cloth.
Tune to first place the basin containing the biogas slurry in the pig's trough to allow it to sniff, give the pig an adaptation process, and wait until it is used to quantitatively mix it into the food to make it eat.
Addition method and amount of biogas slurry Addition standard for pigs is determined by the concentration of biogas slurry. Day heat is appropriate and thin, and day cold is appropriate to thicken. It is advisable to avoid diarrhea after pig food (in order to increase appetite, you can first make pigs Hungry 1-2 times, after feeding); added in 3 stages, one is piglet stage (20-25 kg) 4 times a day, 0.3 kg each time; second is a shelf pig (25-50 kg) daily 3 Times, 0.6 kg each time; Third, finishing pigs (50-100 kg) 4 times a day, each time 1 kg.
Precautions
It is necessary to take fluid from a biogas digester that normally produces gas for more than one month. A diseased pool that does not produce gas for a long period of time or does not produce gas properly cannot be fed to a pig. Biogas slurry cannot be used with it (especially when the concentration is extremely high). After taking it out, it should be rotated for 15-30 minutes to ensure the volatilization of ammonia and prevent the contamination of bacteria. The amount of biogas slurry must be controlled flexibly, depending on the feed intake of the pig, and it is not advisable to eat it after eating. If there is any surplus, appropriate reductions are made. If you wash the house with biogas slurry at least 3 times a week, the pigs get less disease and the synergy is more obvious.
