Cows feed concentrates with buffer
In order to increase the milk production of dairy cows, most cattle raising households increase the amount of concentrate feed. After eating a large amount of concentrate, the cow will quickly ferment and form large amounts of acid in the rumen. In addition, the beef will eat less, The amount of saliva secretion is also reduced, often resulting in indigestion, even causing true gastric translocation, ketosis, and acidosis. The solution is to add appropriate buffers (sodium bicarbonate, sodium carbonate, magnesium oxide, bentonite, or grass ash, etc.) to the dairy cow diet. The benefits: First, it can improve the feed intake of dairy cows, and increase and stabilize milk production. Amount, while keeping the milk fat rate from falling. The second is to maintain the hydrogen ion concentration in the rumen, intestinal contents and body fluids of cattle, and to buffer the influence of volatile fatty acids in the rumen on the hydrogen ion concentration and prevent the rise of rumen acidity. The third is to dilute the rumen fluid and increase the outflow velocity of rumen fluid. At the same time, it increases the concentration of acetic acid, increases the ratio of acetic acid and propionic acid, and further increases the milk fat percentage. The fourth is to effectively prevent ruminal acidosis, improve disease resistance, and promote the health of cattle. Such as grass ash has the function of disinfection, sterilization, astringency, clean up the gastrointestinal absorption of harmful ingredients in the intestine, can neutralize stomach acid. The author's experiment using grass ash as a buffering agent showed that 3.5% of plant ash was added to the diet of dairy cows after delivery. Compared with the control group, the feed intake and milk production were increased by 10% and 13% respectively, and the incidence of gastrointestinal tract was increased. obviously decrease. Buffering agents should be used in the following situations: (1) High-yield dairy cows at the beginning of lactation. (2) When the concentrate in the diet accounts for 50%-60%. (3) Long-term feeding of silage, or coarse material is almost all bad residue feed. (4) In the early period of lactation, the diet was high-precision, high-dregs feed, and the quality of the coarse material was poor. (5) In the summer, the appetite of lactating cows decreased, and dry matter intake was significantly reduced. (6) When the milk fat rate of the regular milk produced in the lactating herds declines significantly. (7) When the lactating cattle diet is converted from coarse material type to fine material type (60% of concentrate material and 40% of coarse material). (8) When the diet is fed separately from concentrate and coarse material. The amount of buffer: (1) The amount of sodium bicarbonate: calculated as the dry matter intake of the diet is 0.9%-1.5%; calculated as the concentrate is 1.4%-3%. The amount of sodium carbonate (food base) is exactly the same as sodium bicarbonate (baking soda). (2) The amount of magnesium oxide: 0.2% - 0.4% of the dry matter weight of the diet or 0.6% - 0.3% of the amount of concentrate; or 2 - 3 parts of sodium bicarbonate mixed with 1 part of magnesium oxide, The amount of dry matter for the diet of 0.6% -0.8% or 1.6% -2.6% of the amount of concentrate. (3) The amount of expanded soil is from 0.6% to 0.80% of the total dry matter of the diet, or from 1.2% to 1.6% of the concentrate. (4) The amount of plant ash: 2% - 3% of the total dry matter of the diet or 3% - 4% of the amount of concentrate. (5) For high-yield dairy cows with a daily output of more than 30 kilograms of milk, add sodium bicarbonate and add an appropriate amount of magnesium oxide or bentonite.
