The corn kernels in the northern corn-producing areas are rich in resources, but they are generally used as fuel only and have not been well developed and utilized. Many cattle farmers have thought of using corncob to raise cattle, but they can't help but have a hard texture and bad taste, and they are not suitable for direct use in raising cattle. Today I introduce to you a corn cob fermentation technology, can fully use the corn cob, opened up a new source of feed for cattle.

The nutritional value of corn cobs. The corn cob contained 54.5% soluble sugar, 29.7% crude fiber, 2.2% crude protein, and 0.4% crude fat. It also contained various mineral elements such as sulfur, magnesium, iron and potassium. Can be used as a quality rough feed resource.

Corn cob fermentation principle. Corn cob fermentation requires the addition of an appropriate amount of enzyme preparations, using the enzyme's biocatalytic decomposition function, to deal with poor palatability, indigestible corn cobs to improve palatability and digestion and utilization, so that its nutrients can be fully absorbed and utilized by cattle. At the same time, the addition of enzyme preparations to the feed helps the digestion and absorption of cattle, promotes growth, improves production performance, and reduces odor and pollution of excrement.

Specific steps:

1. The construction of a fermentation tank. Fermentation ponds should be constructed in places with high terrain, good drainage, hard soil, sheltered from the sun and no contamination by feces. Fermentation ponds are generally rectangular in shape and can be made of cement or bricks, or they can be laid directly after digging earth pits. The size of the fermentation tank should be designed according to the number of corn cobs, and generally, 3 to 4 liters of fermentation tank per ton of corn cob (dry) is required.

2. Corncob processing.

(1) Select corn cobs that have not been mildewed or spoiled, and remove impurities such as sediment.

(2) Using a pulverizer to comminute the corn cob into pieces 0.5 cm in length and width for better fermentation and digestion.

(3) The comminuted corn cobs must also be soaked (or sprayed) with appropriate clean water to keep the moisture at about 65% to 70%.

3. Add enzyme preparations. 1.5 kilograms of enzyme preparation per ton of corn cob is required. In order to evenly mix the corn cob with the enzyme preparation, 20 kg of corn and 30 kg of wheat bran can be used to premix the enzyme preparation, and then evenly mix in the corn cob. In addition, premixed enzyme preparations can also be added while loading, which saves a portion of the labor force and can also be uniformly mixed.

4. Fill the seal. Disinfect the bottom and all sides of the fermentation tank so as to prevent the mixing of bacteria into the fermentation effect and the quality of the corn cob. The corn cobs need to be filled layer by layer. Each load of 20 to 30 centimeters needs to be compacted once, and the air should be drained as much as possible. After filling, it needs to be covered with plastic cloth in time, and soil is pressed on top and all sides to prevent air from entering.

5. Quality identification. Generally 2 to 3 days in summer and 7 to 10 days in winter, the corn cob after fermentation can be stored for 6 to 8 months without deterioration under the condition of sealing. High-quality fermented corn cobs are yellow-white, with a strong scent of wine, a relatively soft texture, and a slightly moist texture. If blackening, sour odor, and clumping occur, it proves that the fermentation has failed and cannot be used for cattle breeding.

6. Feeding. A small amount of corn cob can be added to the feed first, and then gradually increased after the cow is acclimated. If diarrhea occurs in cattle during this process, corncob feeding or stopping can be appropriately reduced and then fed again. For more acidic fermented corncobs, care should be taken to feed pregnant cows to avoid miscarriage. The feed should not be entirely made of fermented corncobs, and it should be reasonably matched with other roughages and concentrates so that its nutrition can be more comprehensive and balanced. Under normal circumstances, adult cattle are fed 8 to 12 kilograms a day and calves are fed 3 to 5 kilograms a day. Http://Content/f6da5947-374b-4846-8843-b03b4196f48a?cType=2
