How to increase dairy milk production
In recent years, many new technologies have been successfully developed at home and abroad to increase the amount of milk produced by dairy cows. The use of these new technologies can increase milk production, reduce feed costs, and increase economic efficiency. Specifically speaking there are three grasping: Grasping feeding new technology feeding congee material. First, add a little salt and a small amount of water to the powdered concentrate, stir well, then pour it into a pot that has been boiled with water, and stir for 5-10 minutes to serve as a congee. Cows fed with porridge are 13% more milk-producing than dry-wet feeds, because clinker is easier to digest and absorb than raw materials. Feed the shell sunflower seeds. Adding 10% to 20% of shellfish sunflower seeds to the cow's feed can increase milk production by about 15% due to its rich protein and fat content. Feed fermented corn stalks. Combine the crushed corn stalks with 2-3 cm straw or mountain grass, add 0.2-0.5 kg of salt per 50 kg, 70-80 kg of water, mix well and put cement into the concrete pool, cover the plastic film. And grass, after 1-2 days when the pool temperature rose to 40 °C, uncovering and cooling can be used for feeding. This method can significantly improve the palatability and feed intake and milk production. Feed pine herbs. In Canada, loose vanilla is commonly used as a feed for dairy cows, which can increase palatability and feed intake. It can produce 1 kg more milk per day than feeding corn. Hi sweet sorghum. Feeding sweet sorghum to cows produces 0.5-1 kilograms more per day than feeding corn, because it contains more nutrients than corn. Feed citrus leaves. The citrus leaf fermented prolactin feed developed in Japan can increase milk production by about 30%. Citrus leaves were collected during pruning in early spring, washed and cut into small pieces, and then a small amount of beer was used as a starter and placed in the silage, and they were fed for 10 days. Feed apple cider vinegar. In the United Kingdom, there is a 17-year-old dairy cow that produced 159 tons of milk during the 13 lactation periods, setting a world record. The reason for its high yield is that 1.5 ml of vinegar made from apple juice is fed every week. Feed cottonseed. In the United States, adding 20% ​​of cottonseeds to dairy cows has a significantly higher milk production than conventional feeders. Sunflower and corn mixed silage. The United States uses 60% corn and 40% sunflower mixed silage to feed dairy cows, the milk production increased by 5%, the average daily gain of growing cows increased by 9% -10%. Grasp the supplement feeding method to add honey pollen. Adding 10% honey pollen to the cow's feed can increase milk production by 5%-10%. Add fat. Adding 3% to 5% of animal fat in dairy cow's feed, and appropriately increasing calcium content in feed, can improve feed palatability and increase digestibility, thereby increasing milk production. 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. Add fish and shrimp. Adding cooked boiled shrimp 0.3 kg/head on cow's feed can increase milk production by 2 kg. Adding 0.75 kg/day of fishmeal at the beginning of lactation can increase milk production by about 1.5 kg. 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%. 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. 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 significantly increase the milk production by more than 10% and increase the weight gain by 5%-10%. Add urea. The addition of urea to cows, which account for 2.5% of concentrate (less than 150 grams), can significantly increase milk production without poisoning. 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 kilograms per day. In the summer, it supplies erythritol, which has the same effect. Grasp the management of new technologies to protect the breasts. In winter, cows are kept warm with cotton bras to prevent cold and freeze. In summer, the bras are placed on the cover to prevent ants from biting and increase milk production. 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. Trimming cow's hooves. Quarters trimming hoof hooves once (especially at the beginning of autumn and early spring) can increase milk production by 1-2 kg per day. Increase lighting. Illumination is increased from natural light 9-10 hours to 13-14 hours, and fluorescent lamps can be used to make up for lighting time, which can increase milk production. 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%. Avoid noise. When the noise reaches 68-74 dB, it can cause cows to reduce production and raise the degree of bovine lactate. If the noise pollution is too long, the milk production function can hardly be restored. Therefore, the cow's cow house should be kept away from noise in factories and mines to avoid noise pollution.
