Method for fermenting swill by using nongshengle feed starter;

40-50% of swill is fermented by swill feed starter, and the formula is: wheat bran: rice bran: swill is mixed at the ratio of 30%: 30%: 40%, and it is better to drain it when the water content is high, and the Nongshengle feed starter is increased at the ratio of 3 ‰, and the water content is controlled at 60%. The way to judge whether the water content is appropriate is to hold the mixed materials tightly with your hands, and they can form a ball. They don't drop when they see water, but they will disperse when they land. Then put it into a fermentation tank (with a tank that can hold one or two tons of materials) for sealed fermentation, and the fermentation can be completed in 3-5 days. Cover it after each use, and it will last for more than half a year.

It is best to feed fermented feed in the following proportion: fermented feed: purchased full-price feed (or self-made full-price feed) = 60-70%: 40-30%. That is, fermented feed made from swill can replace 60-70% of the total feed. Fermented swill feed does not need to be mixed with half of fresh swill, and can be directly mixed with fermented swill feed, or mixed with a part of purchased full-price feed, or self-made full-price feed. The preparation method of full-price feed is determined by the user: corn flour and wheat bran account for 88-89% (according to the size of animals and the nutritional needs of different growth stages, the ratio of corn flour and wheat bran can be 30%: 70 respectively). That's how I found them.

So what are the benefits of using Nongshengle feed starter to ferment swill?

It avoids the trouble of traditional cooking: usually, when pig food is fed to pigs, it is very troublesome, time-consuming, laborious, expensive and requires equipment. The unfermented swill can only be fed to pigs above 100 kg.

The change of physical and chemical properties of swill makes it more convenient to raise pigs: after Dai's experiment, fermented swill can feed 50 kg of piglets without causing diarrhea. On the contrary, unfermented swill, even if cooked, can't feed pigs under 100 kg. In this way, the cost of raising pigs is greatly reduced.

The fermented swill can replace 80% wheat bran and corn flour predicted by full-price feed.

Swill can be stored purposefully for more than half a year.

I hope these are useful to you!
