First, raise new technology
1. Feed congee material. Add a little salt and a small amount of water to the powdered concentrate, mix well, pour into a boiling water pot, and stir for 5 to 10 minutes. The milk production from congee feeding cows is 13% higher than that from feeding dry and wet materials because clinker is more easily digested and absorbed than raw materials.
2. Feed oyster shell sunflower seeds. Adding 10% to 20% of shellfish sunflower seeds in the cow's feed can increase the milk production by about 15% because it contains rich protein and fat.
3. Feed fermented corn stalks. Combine the crushed corn stalks with straw that is 2 to 3 cm long, add 0.2 to 0.5 kg of salt per 50 kg, and add 75 to 80 kg of water. Mix well and put them into the cement pool. Be sure to cover the plastic film and grass.è‹« è‹« è‹« è‹« è‹« 1 1 1 1 1 1 1 1 1 1 1 1 1 1 è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹« è‹«This method can significantly improve palatability, feed intake and milk production.
4. Feed sweet sorghum. Feeding sweet sorghum to cows produces 0.5 to 1 kg more milk per head per day than feeding corn because it contains more nutrients than corn.
5. Feed citrus leaves. The citrus leaf fermented prolactin feed developed in Japan can increase milk production by about 30%. In the early spring pruning branches collected citrus leaves, washed and cut into filaments, then mix in a small amount of beer as a starter, into the silage, sunflower and corn mixed silage. When Americans feed cows with 60% corn and 40% sunflower mixed silage, their milk production increases by 5%, and the average daily gain of growing cows increases by 9% to 10%.
Second, add supplemental feeding method
1. Add honey pollen. Adding 10% honey pollen to the cow's feed can increase milk production by 5% to 10%.
2. Add fat. Adding 3% to 5% of animal fat to dairy cows' feed, and appropriately increasing the calcium content in feed, can improve feed palatability and improve digestibility, thereby increasing milk production.
3. Add carotene. In the dairy cow diet within 30 days before birth and within 92 days after delivery, adding 7 grams of carotene preparation per day can increase the net milk production by 200 kg during the whole lactation period.
4. Add fish and shrimp. Adding cooked boiled shrimp 0.3 kg/head on cow's feed can increase milk production by 2 kg. In the early stage of lactation, 0.75 kg/day of fishmeal was added, and about 1.5 kg of milk was added.
5. Feed apple cider vinegar. In the United Kingdom, there is a 17-year-old cow with 159 tons of milk produced during the 1.3 lactation period, which is the highest in the world. The reason for its high yield is to feed 1.5 ml of vinegar made from apple juice every week.
6. Feed cottonseed. When Americans add 20% cottonseeds to the dairy cow's feed, their milk production is significantly higher than those who do not.
7. Add potassium iodide. With potassium iodide 5 mg, sodium sulfate 30 g mixed with concentrate, fed once every two days, can increase milk production by about 10%.
8. Add baking soda. Adding 150 grams of baking soda to the first day of the cow's lactation can increase milk production by 30%. In the average diet containing 60% concentrate and 40% coarse material, 1.5% of sodium carbonate and 0.8% of magnesium oxide were added, and evenly mixed cows could increase milk production by 3.8 kg/head day.
9. Add urea phosphate. The addition of urea phosphate at a rate of 1.4% of the concentrate during the lactation period of dairy cows can increase the milk production by more than 10% and increase the weight gain by 5% to 10%.
10. Night feeding. Feeding 1 kg of hot clinker to lactating cows at 11 o'clock in the winter at night can increase milk production by more than 2 kg per day. In the summer, the liquid material is replenished and the effect is the same.
Third, management of new technologies
1. Protect breasts. In winter, cows are kept warm with cotton bras to prevent freezing and freezing. In summer, the bra is covered to prevent mosquitoes from biting and milk production can be increased.
2. Hot and cold head. The hot water bag is fixed between the two corners of the cows, filled with hot water in winter, and filled with cold water in summer to reduce hot and cold stress and increase milk production.
3. Trimming cow's hooves. Quarters of hoofs are trimmed once a quarter (especially at the end of the spring), which can increase milk production by 1 to 2 kilograms per day.
4. Increase lighting. The light is increased from 9 to 10 hours of natural light to 13 to 14 hours, and the fluorescent lamp can be used to make up for the lighting time, which can increase milk production.
5. Night exercise. At 12 o'clock in the evening, the cows are sent to the playground for a period of time, which can promote appetite and increase feed intake, and can increase milk production by about 10%.
6. Avoid noise. When the noise reaches 68 to 74 decibels, it can cause cows to reduce production and increase the degree of bovine lactate. If the noise pollution is too long, the milk production function will be difficult to recover. Therefore, the cow's cow house should be kept away from noises such as factories and mines to avoid noise pollution.

Corn has a rich variety of genes, under the guidance of these genes, will produce different colors.Most of these maize varieties are the expression of some anthocyanins produced in the grain under photosynthesis, and different anthocyanins cause different colors.
Black corn skin is black, this kind of corn is more rare, and the nutritional value of black corn is very high, whether it is the type of amino acid or the content of trace elements are far higher than other kinds of corn, eating black corn has a protective effect on the human five viscera, but also to keep the body perfect.
