14 cases of milking good milk cows
1, Add fatty acid calcium method. Experiments conducted at the Hoe Tan Farming Research Institute in Hokkaido, Japan, showed that the addition of calcium fatty acids to feeds can increase milk production in dairy cows. The 12 cows tested were randomly selected and 2.2% of calcium fatty acid was added to the same diet as the control group. Other feeding conditions were the same. The duration of the trial was 105 days in the 1 lactation period. The results for the trial group were: Fatty Acid Calcium Increases Neutral Fat and Phospholipid Content in Dairy Cows, Average Milk Yield per Day Increases 7.5 Kg More Than Control. Therefore, it can be confirmed that fatty acid calcium is an ideal milk additive for dairy cows. 2, Add phosphogypsum method. Phosphogypsum in addition to rich in sulfur, calcium, but also contains a certain amount of potassium, sodium, iron, strontium, barium and so on. The addition of 15 grams of phosphogypsum per day to the basal diet of dairy cows increased milk production by 17% and milk fat percentage by 10.5%. 3, Tim feeds baking soda. U.S. scientific research personnel added 150 grams of baking soda to each cow during the lactation period of dairy cows. As a result, acidosis was avoided, feed intake was increased, feed utilization was improved, body immune function was enhanced, and heat stress was improved. Rumen B The increase in acid salt inhibits the synthesis of propionate, so the peak period of milk production is advanced, milk production is increased by about 30%, and the milk fat percentage is increased by 8.4%. In addition, the estrus-free dairy cows were fed with 100 grams of baking soda mix per day for 5 days, and the estrus rate was significantly increased. 4, feeding sweet sorghum method. Sweet sorghum is rich in nutrients, with higher protein, fat, nitrogen-free extracts, and coarse ash content than corn, and crude fiber is lower than corn. According to experiments, dairy cows fed sweet sorghum have an average milk yield of 0.8 to 1.7 kilograms per day and a milk fat percentage increase of 3 to 6 percent per day compared with cows fed corn. 5, feed seaweed powder method. Norway has added 4% of algae powder to lactating dairy cows' feeds. After milking, the milk production has increased by 6.8%. The iodine content of milk has increased from 0.1 mg/l to 0.6 mg/l, which can prevent iodine deficiency and mastopathy. The incidence decreased by more than 90%. 6, fed fermented corn stove method. In the United States, corn is abundant. In recent years, research on the replacement of pasture with corn stalks has been very active. Among them, the method used to increase the milk production of dairy cows by using fermented corn stalks to feed dairy cows at the Institute of Feed Research in California, USA, was successful. Fermented corn stalks method: Several cement pools are built inside and outside the house. The crushed corn stalks are mixed with about 3 kilograms of mountain grass or straw (the proportion is based on the facts) and salt is added for each 50 kg of material. 0.2-0.5 kg, 75-80 kg of water (heat in winter and cool in summer), mix well and put it into concrete pool, and then put on plastic bottom film, and use bricks to compact the four sides and cover it with grass. 24-48 hours after the temperature measurement, until the temperature rose to 40 °C, uncover the cover after cooling down to room temperature after feeding. 7. Feed fresh lees and baking soda. For lactating dairy cows, feeding 10 kg of fresh brewer's grains and 100 grams of baking soda per head per day, the milk production increased by 6.8%, the milk fat percentage increased by 0.1%, the monthly increase in body weight was over 1 kg, and the feed remuneration increased by 6.2%. Benefit increased by 9.2%. 8, feed hollyhock seed method. British researchers add 10-20% hollyhock flower seeds to the feed of lactating cows. Because hollyhock flower seeds are rich in protein and fat, the milk production of lactating dairy cows is greatly increased, and the experiment has increased by more than 15% compared with the control group. 9, feed citrus leaf feed method. Japan has developed a citrus leaf fermented milk-promoting feed for lactating dairy cows that can increase milk production by about 34%. Citrus leaf fermented beverages are produced by pruning citrus trees in early spring, collecting and washing the citrus leaves, cutting them into pieces, mixing a small amount of beer as a starter, mixing them into a silage, and fermenting them. 10 days can become citrus leaf fermented milk feed. 10, feed congee material law. The experimental data show that the milk production of dairy cows can increase milk production by more than 13% compared with feeding dry and wet materials. The processing method of porridge materials is to dilute the fine powdered material with a small amount of water first, and dry the material block to dry. After the water in the pan boils, pour the material into the pan and stir it for 5-10 minutes. Water ratio: 1:1 (10-15) in winter and 1: (20-30) in summer. Fine ingredients can be added with a little salt to increase palatability. Concentrates can all be converted to congee feed, but also some dry and wet grass feed. 11, feed nitrogen, sulfur method. French researchers, the urea, mirabilite with water into a 1:2 solution, according to each ton of silage beverages plus 5 kg of urea and 0.5 kg of Glauber's salt ratio, evenly mixed in the barley, green corn feed to be stored, can be Silage crude protein increased by 1.9% and carotene increased by 37%. Cows' milk production after food increased by 8.4% and fat content increased by 5.3%. 12, Tim feed milk spirit. The milk-enhancing name is carbonyl = amine phosphate, which does not contain hormones and peony, and is intended for ruminants. It provides non-protein nitrogen and phosphorus nutrient feed additives for ruminants. According to foreign data reports, when each cow feeds 75-200 grams of milk-enriched milk daily, the milk yield is increased by 10-20%, milk production per kilogram can increase milk by 10-30 kg, and the milk fat content can be increased. More than 10%; At the same time can enhance the absorption and use of calcium in dairy cows, so that the cattle's good lyrical, normal function, milk quality. 13, Tim feed salt method. During the lactation period, cows need more chloride ions than usual. If the cow's diet contains insufficient chloride ions, it will lead to metabolic disorders in the body and the balance of physiological functions will be lost. In order to ensure the health of dairy cows during production, dairy cows will produce more milk. In addition to feeding cows protein-containing materials, 1.8-2.4% of salt should be added to feed to meet the chlorine ion requirement of cows. According to the experiment, dairy cows fed with salt increased milk production by more than 15% compared with the control group. 14, add feed magnesium oxide and baking soda. During the lactation period, cows add 0.8% magnesium oxide and 1.5% baking soda, which can increase the output of fresh milk by about 4 kilograms per head per day. It is more effective for dairy cows fed silage for a long period of time.
