Biogas slurry raising technique
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 that pigs can be slaughtered more than one month in advance. Each pig saves about 60 kg of feed and saves 80 to 100 yuan for fodder and epidemic prevention, which brings considerable economic benefits to farmers. benefit. The main technical points are as follows: Biogas slurry intake: Take fluid from biogas digesters that normally produce gas for more than one month. Take off the floating foam on the surface of the biogas slurry before taking it, and take the clear liquid from the top 40 centimeters to 70 centimeters and filter it with sand cloth. Tuning: First, the basin containing the biogas slurry is placed on the side of the pig's trough to allow it to sniff, and the pig is given an adaptation process. After being used, it is quantitatively mixed into the food to make it eaten. Addition method and dosage: The standard for the addition of biogas slurry to pigs is determined by the concentration of biogas slurry. It is appropriate to dilute some of the heat on the days, and it should be thicker in the cold days. It is advisable to avoid diarrhea after eating pigs (in order to increase appetite, it can be used first. The pig was hungry for 1 to 2 times and then fed); added in three stages: first, piglet stage (20kg-25kg) four times a day, 0.3kg each time; second, shelf pig (25kg-50kg) three times a day , 0.6kg each time; Third, finishing pigs (50kg - 100kg) four times a day, each time 1kg. Precautions must be taken from a biogas digester that normally produces more than one month of gas production. Long-term non-producing gas or diseased pools cannot produce fluids to feed pigs. Biogas slurry cannot be used with it (especially if the concentration is extremely high). After taking it out, it should be rotated for 15 minutes to 30 minutes, which ensures the volatilization of ammonia and prevents 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 three times a week, your pigs will get less disease and more effective.
