Fresh cassava fermentation and feeding method

This operation technology can also be applied to other potato roots, such as fresh sweet potato, fresh potato fermentation treatment: ES2 China Feed Industry Information Network - based on feed, service animal husbandry

In fresh cassava roots, the water content is generally about 70%, protein is 1%, crude fat is 0.2%, starch is about 28%, and vitamin content is very rich. Since fresh cassava contains a large amount of toxic substances of hydrogen cyanide, direct feeding can cause animal poisoning. The use of roughage degradation agent to treat fresh cassava can not only remove the toxins, but also directly feed the animals without cooking, and the nutrition, digestion and absorption rate are also greatly improved.

The key to the treatment of cassava is to ferment the toxic substances of hydrogen cyanide. At the same time, fresh cassava has a large amount of pectin, which makes the processed cassava produce more acid and is difficult to decompose, so it is best to cut it into silk or Broken, every 400 kg of shredded potato + 60 kg of rice bran or wheat bran + 20 kg of corn flour + a packet of roughage degrading agent and half-package of 99 raw yeast (mixed with 10 kg of corn flour first) + salt 1.5 kg + urea 1 kg (can also be added, urea is added to increase the protein content, so that the microorganisms in the fermentation absorb the nitrogen synthesis of bacterial protein in urea) + 30 kg of soybean meal (peanut meal, vegetable meal can be added Insufficient protein) Stir well, press into the tank, or other containers, pay attention to pressing or stepping on it. Use plastic film on it, seal it well, treat it for a few days, preferably for more than ten days, have aroma (wine Aroma or sour aroma).

If the premix is ​​insufficient in the fermented material when the ingredients are fermented (provided that the premix does not contain antibiotics, it will inhibit the fermentation), such as adding 4% of the premix of 2% per 100 kg of fermented wet material. (At this time, the addition of salt should be cancelled), after fermentation, the animal can be directly replaced by part of the full-price feed.

Note that there is no need to add additional water to the ingredients. All the water comes from the raw materials of the potato chips. The water content of this formulation is calculated to be around 56%. Although it looks very dry before fermentation, water will permeate during the fermentation, and the water content will appear to increase after fermentation. The crude protein content of the potato material after fermentation is 12% or more. ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

When feeding, if it is too acidic, you can add a small amount of baking soda to neutralize. For example, add 1~3 kg of baking soda to each 100 kg. Neutralize with sodium carbonate powder, that is, limestone powder, small. Soda powder or calcium carbonate powder must be added during the pre-feeding ingredients for neutralization (not to be added before or during storage).

Feeding can not be too single, can not use the degraded cassava to feed the pig, otherwise the nutrition is too single, nutrition is not complete, it is best to feed with other materials, pure cassava is energy feed, protein is missing, so it is best to In addition to the protein feed, as described above, some protein feeds such as cottonseed meal are added during the degradation, and at the same time as the degradation, the rapeseed meal and the cotton aphid are also detoxified.

Before feeding, the fermented cassava taken out is best exposed to dryness, and the poison gas is volatilized to completely detoxify. ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

The following is a reference formula for feeding pigs after degrading pure cassava (without adding soybean meal, etc.). Since the treated cassava is wet, the weight of the weighing should be multiplied by 2 when using, for example, 100 kg of feed is prepared, if used. It is 20%, please use 40 kg instead of 20 kg for actual preparation. ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

Reference formula for feeding pigs, for reference only: 40 kg or more to start degrading cassava, 40 to 100 kg formula: 20% degraded cassava, 35% corn flour, 26% soybean meal, 3% fish meal, 15% wheat bran, hydrogen phosphate Calcium 1%, bone powder 1%, premix additive 1%. ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

Large pigs above 100 kg, degraded 30% of cassava silk, 30% of corn flour, 18% of soybean meal, 7% of peanut bran (or cotton bran), 12% of wheat bran or polished rice, 1% of calcium hydrogen phosphate, 1% of bone meal , premix additive 1%, etc. ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

If 4% of the premix is ​​added to the fermentation together with the soybean meal (such as the fermentation method described above), the fermented material can be used directly instead of part of the full-price feed. Of course, when feeding for the first time. Must be tested in small amounts, such as 10% test feeding, if the pig adapts to love, you can slowly increase the dosage after a few days, until it does not adapt, and reduce the amount by 10%. The specific feeding methods are as follows: (Appropriately increase the dosage once every 3 days) ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

1 First test: 10% fermented material + 90% full-price feed; ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

2 Second feeding: 20% fermented material + 80% full-price feed; ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

3 The third feeding: 30% fermented material + 70% full-price feed; ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

If you adapt to eating, you can also increase it appropriately, but it is recommended that no more than 40% is appropriate. ES2 China Feed Industry Information Network - based on feed, serving animal husbandry

The other method of cassava utilization is (more troublesome), slicing or shredding, boiling, picking up, drying, smashing and using it as an energy feed. Four pounds of fresh potatoes can get a pound of potato flour. This digestion and absorption rate has also increased. It should be equivalent to the effect of using a degradation agent. Feed the pigs according to the above formula, but be sure to add a pack of roughage degrading agent to each of the 400 kg of feed, because 20-30% of the potato powder is used instead of the corn flour (instead of the conventional feed). The amount of corn flour in the formula), in fact, the nutritional value of potato flour and corn flour still have a lot of gaps, so the use of degradation agents to improve digestion and absorption rate to make up for this deficiency. As long as before feeding, every 100 kg of this kind of feed plus 120 kg of water to wet, can be fed, of course, after wetting, it is better to put it after one hour of feeding.
