First, the nutritional value of wet corn corn wet corn mainly refers to the fuel ethanol plant with modern technology and equipment, the use of corn seed and selected yeast mixed fermentation production of ethanol and carbon dioxide, the remaining solid fermentation residues. Corn wet food has high nutrient content and no starch, and can be directly fed to livestock such as beef cattle, dairy cows and pigs.
The crude protein content of corn bran wet-dried was as high as 27% to 29%, exceeding that of corn, bran, etc. Crude fat was more than 5%, crude fiber content was less than 8.5%, crude ash was less than 4.5%, and lysine content was low. , Other amino acids are abundant, especially methionine is very rich. Calcium, phosphorus and other minerals are complete. The content of B vitamins is very high. Therefore, corn wet grain is a good protein feed suitable for ruminants of cattle and sheep. Corn wet grain and corn grain have the same feeding effect, even better than corn dry grain.
Second, corn wet technology to feed lactating calves technical points in addition to Charolais and Heterodex hybrid cows, usually low lactation, three months after calving, mother milk can not meet the growth needs of calves, which Feeding is very important for the growth of yak, and yak is very efficient in feeding materials. The weight-reducing effect of feeding is 2.8:1. Feeding calves weigh more than 200 kg at 6 months of weaning.
The recommended formula for corn wet meal is: corn 45%, dried corn wet 20%, bran 6%, soybean meal 3%, cottonseed meal 9%, corn stover meal 13%, calcium hydrogen phosphate 1%, table salt 0.5 %, 1% for baking soda, and 1.5% for yak premix.
Third, the technical aspects of corn wet corn feeding The corn wet cereal is an excellent source of rumen protein needed for normal cow breeding, can increase cow postpartum weight and increase reproductive rate.
The recommended feed formula for young cows fed corn grain was: corn 45%, dried corn wet 50%, calcium hydrogen phosphate 1%, salt 1%, baking soda 1.5%, and cow premix 1.5%.
The recommended lactating cow feed formula for feed corn and corn grits is: corn 24%, dried corn wet 45%, bran 8%, soybean meal 6%, cottonseed meal 12%, calcium hydrogen phosphate 1%, salt 1%, Sodium bicarbonate 1.5%, lactating cow premix 1.5%.
Fourth, corn wet technology feeding rack cattle technical points Shelf cattle usually refers to weaning yak mainly to add a small amount of concentrate feed to the age of one year or half, this is the traditional Chinese feeding methods, the purpose is to make the beef cattle body fast The size required for fattening. With the development of science and technology, beef cattle in the shelf stage is the fastest growth rate of beef cattle, the best feed compensation period, the use of new breeding methods, the annual beef cattle weight at least reached 400 kilograms.
The recommended new type of feed for corn cattle is: 32% corn, 50% corn bran wet, 5% soybean meal, 8% cottonseed meal, 1% calcium hydrogen phosphate, 1% salt, and 1.5% sodium bicarbonate. Beef premix 1.5%.
5. Technical points for feeding fattened cows from wet corn grits The starting weight of fattening cattle shall not be less than 300 kg until the stage of fattening to 500 kg; mainly increasing daily weight gain; at the stage of 500 kg to 700 kg, In order to improve the inter-muscular fat of beef cattle, to improve the degree of fat coverage, improve the fat marble pattern.
It is recommended that fattening cattle be fed corn wet bad diet formula: 45% corn, 40% dried corn wet, 3% soybean meal, 7% cottonseed meal, 1% calcium hydrogen phosphate, 1% salt, 1.5% sodium bicarbonate, beef cattle Mixing 1.5%.
6. Precautions for Feeding Different Stages of Beef Cattle
1. The corn wet grain is acidic (pH-4.8), and it is necessary to add the food base (NaHCO3). The proportion is 0.8% to 1.3%, and it is adjusted to neutrality, and it can be used after stirring. This will increase the palatability and feed intake of cattle. After 10 to 15 days of adaptation, baking soda in the recommended formula can be used.
2. At the beginning of feeding corn wet cereal, some beef cattle refused to eat, should be added in small quantities, and then increase gradually until the beef cattle adapt to the corn wet grain feed, stabilize the corn wet grain feed intake. The adaptation period for feeding corn wet grains is not less than 15 days. After the beef cattle are fully adapted to the odor of the corn wet trunk, the above-mentioned recommended formula can be used. After 15 days, the daily feeding amount of one grain of corn and corn must not exceed 6 kg.
3. Calculate the fresh feed amount of corn wet grain and silage corn. Generally, the dry rates of corn wet grain and silage corn are 30% and 40% respectively. In the actual feeding of corn wet grains and silage corn, the calculated amount of dry matter must be divided by 0.3 and 0.4, respectively, which is the actual amount of corn wet grain and silage corn actually fed.
4. If there is no soybean meal protein feed, it can be completely replaced by cottonseed meal, which will not affect the growth performance of beef cattle.
5. The wet corn grain is stored for a long time. Its surface is susceptible to mildew, mildew, and deterioration of corn wet grains. Never feed cattle.
6. The mix of fine and coarse materials should be reasonable, and the proportion of concentrate feeds generally accounts for 50% to 70%. Beef cattle are fed on a daily basis with 100 kg live weight 1.2 kg. Cows are fed daily with 100 kg of live weight 0.6 kg to 1 kg of concentrate; daily feeds for roughage are calculated based on 100 kg of cattle weight 2.5 kg. .
7. Operation method for feeding corn wet grain The newly-purchased beef cattle shall be placed in the isolation area to be observed for isolation of not less than 15 days. After confirming the health of the beef cattle, dry corn stalks or dried corn stalks and silage corn shall be used. Mixing and adding some concentrated feeds for adaptive feeding. In this process, each head of beef is given insects such as ear numbers, nose pliers, immunity, and oral worms. After the end of adaptive feeding, each beef cattle needs to have Fasting weight records.
The maize wet corn must have a period of adaptation. During the first to third days of feeding, the corn wet weight feeds 2 kg per cow per day; in the 4th to 6th days of feeding, the amount of corn wet per day per cow is 3 Kilograms; on the 7th to 9th days of feeding, the daily feed amount of corn was 4 kilograms per cow; on the 10th to 12th days of feeding, the corn wet kilogram fed 5 kilograms per cow per day; on the 13th For 15 days, the amount of 6 kilograms per day of corn wet cereals was fed. Due to the acidity of corn wet grain (pH-4.8), when the feeding of corn wet cereal, individual beef cattle refused to eat, and it was necessary to add the food base (NaHCO3) to the corn wet grain, and the ratio was 0.8% to 1.3% adjusted to neutral. Stir well and use it to increase the palatability and feed intake of the cow. After 10 days to 15 days of adaptation, the amount of baking soda in the recommended formula can be fed.
After the adaptation period of beef cattle, the total dietary amount of each cow is at least 2.5 kg per 100 kg of live weight of beef cattle, and 1.2 kg to 1.5 kg of corn concentrate is the worst diet.
The crude protein content of corn bran wet-dried was as high as 27% to 29%, exceeding that of corn, bran, etc. Crude fat was more than 5%, crude fiber content was less than 8.5%, crude ash was less than 4.5%, and lysine content was low. , Other amino acids are abundant, especially methionine is very rich.

The recommended feed formula for young cows fed corn grain was: corn 45%, dried corn wet 50%, calcium hydrogen phosphate 1%, salt 1%, baking soda 1.5%, and cow premix 1.5%.
The recommended lactating cow feed formula for feed corn and corn grits is: corn 24%, dried corn wet 45%, bran 8%, soybean meal 6%, cottonseed meal 12%, calcium hydrogen phosphate 1%, salt 1%, Sodium bicarbonate 1.5%, lactating cow premix 1.5%.
