(1) Fennel oil odor can promote milk production in dairy cows. United States Yelabs, a dairy farm in Labama, Chaw, has been experimentally confirmed that the aroma of fennel oil has the effect of promoting milk production in dairy cows. They tested 500 cows and sprayed fennel oil every 3 days in the cow shed (whose aroma could last for 3 days) and sprayed continuously for 3 months. As a result, each cow produced 0.7% more milk per day than the control group. 0.9 kg. At present, this method has been adopted by dozens of dairy farms. Translated from Russia, "Rural Life News" 98.10.25 (2) Feeding kelp can increase dairy milk production Japanese animal husbandry experts believe that seaweed is rich in nutrient-rich feed additives such as iodide, vitamins, and minerals. For example, adding 5% of kelp powder to the basal diet of dairy cows can increase milk production by 5-10%, and it can also increase the cow's estrus rate and conception rate. Translated from Russia, "Animal Husbandry," 98 (11) (3) Feeding cottonseeds can make cows prolific in milk. U.S. experts confirmed that feeding cows with cottonseeds can produce more milk. They conducted two trials. The first trial consisted of dividing the cows into two groups. One group (the control group) was fed conventional standard feed, the other group was replaced with 4 pounds of cottonseeds instead of 4 pounds of conventional feed; the second experiment was the cows Divided into three groups, the first group (control group) was fed with conventional feed, the second group was fed conventional feed with added test grains, and the third group was fed conventional feed with 20% cottonseeds. The first test time was 2 months and the second test time was 3 months. The test results showed that whether the first or second test, all cows fed with cottonseeds had higher milk yields than those without cottonseeds. Translated from Russia "animal husbandry" in 98 years 11 (4) feeding porridge law. In summer, a large amount of cold water in the porridge can help prevent the cows from cooling off. In winter, feeding a hot porridge at about 38°C can enhance the cold resistance of the bovine body and increase milk production by 10%. (5) Add carrots and beets. Washing and chopping carrots and beets, adding 15% to the feed, can increase milk production by 25%. (6) Increase lighting. In the first 60 days of milking, the cows were allowed to receive light for 16 hours per day instead of the natural light in the winter without altering the feed. Milk production increased by 10-30%. (7) Add sodium acetate. Each cow is fed with 200-300 grams of sodium acetate per day. The milk production per day can be increased by 0.7-1.2 kilograms, and the milk fat percentage can be increased by 0.16-0.21%. (8) Add urea. Adding 15–20 g of urea per 100 kg of body weight can increase the milk production by 10%, and the amount of urea added is usually 1.5–2.0% of the total cereal mixture or 1% of total dry matter. (9) Drink magnetized water. Cows drink magnetized water better than normal water, milk production can be increased by 12%, but also enhance the body's ability to resist disease. Method: After the natural water flows out of the faucet, it passes through a water bath with a magnetic field strength of 1500-2000 gauss at a certain flow rate, and the magnetic force lines are cut off and flowed out from the other end tap. (10) Add sodium humate. Adding 12-15 grams of sodium humate to the cows every day can increase milk production by 11%, and produce 1.2-1.4 kg of milk per head per day. (11) Increase the exercise. Each morning, the cows are released one at a time, allowing the cattle to walk 3 to 3.5 kilometers an hour, which can increase milk production by 10-15%. (12) Feed vinegar. Feeding 0.2 kg of vinegar to dairy cows every day can produce more than 1 kg of milk. (13) Feeding baking soda. From the end of lactation to the end of milking, each dairy cow is fed 150 grams of baking soda every day, which can lead to a peak milk production period and a continuous high yield within 8 months. The milk fat rate increased by 0.45-0.48%. (14) regularly deworming. After extermination of parasites in dairy cows with thiabendazole or benzobemidazole, an average of 400 kilograms of milk was produced per cow during 305 days of lactation. (15) Feed the placenta. The postpartum placenta of cows were washed and chopped and soaked in 3%-5% saline solution and then fed to the cows. Each time 200 g, once a day, the effect of milk enhancement was very good. (16) Add silage with various trace elements. Add 2.5 grams of copper sulfate, 5 grams of manganese sulfate, 2 grams of zinc sulfate, 1 gram of cobalt chloride, and 1 gram of potassium iodide to the silage of each ton of cows fed, and increase milk production by more than 10%.
