swill, also known as swill, is a kind of waste water in our life. No matter in rural areas or cities, especially with the vigorous development of catering industry, the swill in hotels is increasing day by day. Don't underestimate swill, as long as you make full use of it, you can get great returns. The leftovers collected from hotels, restaurants, schools, etc. are low-cost and nutritious, and are good feed for raising pigs.

Production steps of fermented swill (swill) as feed:

1. Ingredients: Drain the swill first, then add other ingredients, and lower the water content to about 61% (see the instructions for details, that is, it is appropriate to grasp it by hand and disperse it when it hits the ground). The reference formula is: (1) 61-71% of drained swill; (2) 11% corn flour; (3) 18% wheat bran; (4) 1-2% premix (according to the instructions, premix should be added when full-price feed is made by fermentation, but not when full-price feed is not made by fermentation, and premix can also be added when feeding after fermentation); (5) For example, two thousandths (1.2%) of the professional swill starter of Golden EM bacteria.

2. After fermentation, seal and ferment for one to three days according to the instructions. However, the container should be prepared before fermentation: the self-made simple large plastic bag can be used for pumping and vacuumizing. That is, after the fermented materials are packed inside, a large plastic bag cover is placed on the outer cover to achieve a complete sealing effect, and the fermentation is carried out after pumping and vacuuming. Also use the closed fermentation method of fermentable pool. That is, first build a fermentation tank, the size of which is determined according to your own needs. Generally, it can ferment at least one ton of feed, with a small top and a large bottom. The mouth of the tank is in the shape of a cylinder, and there is a sink around it. After loading the material, press a heavy object on it with an iron pot or a plastic basin, and then fill the sink with water, so it can be completely sealed. Please pay attention to it. It can be fermented in about 3 days.
