1, increase lighting method. According to experiments conducted by scientists at home and abroad, it is confirmed that in the first 60 days of lactation, there is no need to increase feed or change feed formula so that cattle can receive 16 hours of light each day, which is 10% more than that of dairy cows that only receive natural light in winter. the above.
2, feed congee material. According to the test. Feeding congee to cows can increase the milk production by 13% compared with feeding dry and wet materials. Because of the good palatability of porridge, cows love to eat, which increases the intake of 7 and is easy to digest and absorb, thus improving the utilization rate of feed. The addition of large amounts of cold water in summer porridge can cool the cows' summer heat and feed 380c hot porridge in the winter. It can enhance the cold resistance of cattle and increase milk production by 10%.
3, adjust the delivery period. The postpartum period of 3-8 weeks is the golden period of milk production. Summer temperatures are high, and mosquitoes and flies are numerous. Cows have low milk production and high incidence. Dairy cows give birth in summer and the daily milk production is about 10 kg less than in other seasons. therefore. Should plan to breed, so that dairy cows during the puerperium to avoid hot summer, can increase milk production 8% to 10%.
4, Add carrots and beets, according to foreign tests, in the 30 days of prenatal and 92 days postpartum dairy cow diet, after washing and chopping carrots and sugar beets, add 15% in the feed, can increase milk production More than 25%.
5, add feeding soda. According to reports in the US Feed Weekly, feeding sodas to dairy cows can greatly increase milk production peaks and continue to produce high yields within 32 weeks. The specific approach is to feed the soda in the feed to the lactating cows, feeding 150 grams of baking soda per day for the entire lactation period. Some domestic experiments have shown that in 60% of the roughage and 40% of the concentrate balance diet, 150 grams of baking soda and 0.8% of magnesium oxide are mixed and fed to the cows, which can increase milk production by 2.8 kilograms per head per day.
6, regularly deworming. Japan, the United States, Britain and other countries use thiabendazole to drive out the nematodes in the digestive tract of dairy cows, with a dose of 45 grams per head. After 300 days of deworming, an average milk cow can increase milk production by 409 kilograms.
7, Tim feed urea. Feeding 15 to 20 grams of urea per 100 kilograms of cow's body weight can increase milk production by 10%. The amount of urea generally accounts for 1.5% to 2.0% of the mixed concentrate. Or 1% of total dry matter.
8, regular hoof repair. Regular correcting of hoofs can prevent the occurrence of limb and foot-diseases and diseases, ensure that the bottom of the hoof is fully loaded, keep the cow in a correct standing posture, and prolong the reproductive years. Studies have shown that the annual production of milk per cow can increase by 206 kilograms.
9, drink magnetized water. Cows drink magnetized water better than drinking ordinary water, milk production can be increased by 5% -10%, but also enhance the body's ability to resist disease. The method is: After the natural water flows out of the faucet, the flow direction of the magnetic field lines is cut off, and the water channel with a magnetic field strength of 1500-2000 gauss flows out from the other end.
10, feed potassium iodide. 1 month before delivery and 1 to 2 months after delivery, daily increase of 20 mg of potassium iodide per day in the diet has a good effect on increasing the daily milk production and milk fat percentage, and can increase the milk production of the primary producing cattle by 8 %, milk fat rate increased by 18%, cow production increased by 6.6% and milk fat rate increased by 17.75%. At the same time, it also had a significant effect on raising calf's birth weight and improving cow reproductive performance.
11, exercise properly. Tests have shown that it is more appropriate for cows to walk 3 to 3.5 kilometers per hour, not only to increase milk production, but also to increase the reproductive performance of dairy cows.
12, add sodium humate and sodium acetate. Sulfate is the main source of sulfur for rumen microbes. Tests have shown that adding 3 grams of sodium sulfate to dairy cows' daily feed increases the daily milk production of cows by 1.38 kg. The sulfur content of cattle feed should account for 0.15%-0.2% of the dry matter, and its role is to improve dry matter. The digestibility. The loss of appetite in dairy cows in summer has led to a decline in milk production. Sodium acetate is not only an important energy source for the body, but also an important material for synthetic milk fats. It is also a flavoring agent. Each cow feeds 300 grams of sodium acetate three times a day. It can increase milk production by 5.58% and increase milk fat rate by 10.58%.
13, drink warm water in winter. According to experiments, when the temperature is below 12°C, the cattle will drink plenty of cold water, which will lower the body temperature by 1-2°C. To restore normal body temperature, physical exertion is needed, and the milk yield is obviously reduced. Therefore, when the temperature is lower than 15°C, it should be given Dairy cows drink warm water or deep well water to reduce the loss of cow body heat and prevent milk production from falling.
14, adjust the temperature. The optimum temperature range for lactating dairy cows is 4 to 21°C. Exceeding this range will inhibit milk production. In summer, the cattle are cooled, trees are shaded in front of the cowshed window and around the yard, and lawns or pastures are planted, which can effectively prevent the reflection of solar heat, give the cow a cold water bath, install electric fans, take shelters, etc., and the cooling effect is also very good. . Giving warm water to cattle in winter can reduce the loss of calories in cattle and prevent milk production from falling.
15, feeding sweet sorghum. Sweet sorghum is rich in nutrients, with higher protein, fat, nitrogen-free leachables and crude ash content than corn, and crude fiber is lower than corn. According to experiments, dairy cows fed sweet sorghum have increased milk production per day per cow than those fed corn. 0.4-1 kg.
16. Feed the fermented feed. According to the Japanese experiment, milk cows fed with citrus leaves can increase milk production by 34%. Fermented orange leaves are fragrant, sweet, and dairy cows love to eat. According to analysis, the orange leaves contain a phyllophyll, which can promote cow development and milk production, while the content of erythrophyll in ordinary feed is very small. Some experiments have also shown that corn stalks can significantly enhance palatability after fermentation and increase milk production.
17, do not support law. After many years of research, Germany does not put calves in a fixed position, allowing it to move freely within the cowshed. The average milk production per cow per year can be increased by more than 190 kg, and the cows are less sick and have more calving and digestion.
