Buffer should be added to the cow's feed

(I) Benefits of Adding Buffers Buffers mainly include sodium hydrogencarbonate, sodium carbonate, magnesium oxide, bentonite, and ash. Adding buffer to the cow's diet, one can improve the feed intake of the cows, stabilize and increase the milk production; the second is to keep the hydrogen ion concentration of the rumen, intestinal contents and body fluids of the cattle normal, buffering The stomach acid in the rumen makes the pH relatively stable; the third is to dilute the rumen fluid, so that the efflux speed of the rumen fluid is greatly increased, and the acetic acid concentration is increased, the ratio of acetic acid and propionic acid is increased, and the milk fat percentage is increased; It can effectively prevent rumen acidosis, improve disease resistance and ensure the health of cattle. ikE China Feed Industry Information Network - based on feed, serving animal husbandry

Grass ash is an inexpensive buffer. The plant ash contains 5%-10% potassium oxide, and also contains trace elements such as calcium, phosphorus, boron, manganese, zinc and molybdenum. The cows can obviously increase the milk yield after eating. The plant ash is alkaline, has the functions of disinfection, sterilization, effect, cleaning the stomach and intestine, and adsorbing harmful components in the intestinal tract. It is used as a buffering agent to neutralize stomach acid, increase appetite and enhance disease resistance. ikE China Feed Industry Information Network - based on feed, serving animal husbandry

(2) Application conditions of buffers (1) High-yield dairy cows in the early stage of lactation; (2) Concentrates with 50%-60% of concentrates in the diet; (3) Long-term feeding of silage, or almost all roughage (4) When the lactation of the lactating cows in summer is reduced, and the dry matter is significantly reduced; (5) when the milk fat percentage of the lactating cows is significantly decreased; (6) when the lactating cows are from the coarse material type When converting to concentrate type (fine material accounts for more than 50%) ikE China Feed Industry Information Network - based on feed, serving animal husbandry

(3) The amount of buffer (1) sodium bicarbonate; added according to the daily dry matter intake of 0.7%-1.5%, or 1.5%-2% of the concentrate feed; (2) Sodium carbonate (alkali base): 0% of the total dry matter of the diet. 5%-1% added; (3) Magnesium oxide: 0.2%-0.4% of the total dry matter of the diet; or 2-3 parts of sodium bicarbonate mixed with 1 part of magnesium oxide, the amount For the diet dry matter 0.6%-0. 8% added; (4) Bentonite: added according to 0.6%-0.8% of the dry matter quality of the diet, or 1.2%-1.5% according to the amount of concentrate; (5) Grass ash: by day Add 2%-3% of the dry matter of the grain, or add 3%-4% of the concentrate. ikE China Feed Industry Information Network - based on feed, serving animal husbandry

For high-yield cows with a daily milk content of more than 30 kg, add magnesium carbonate or bentonite while adding sodium bicarbonate. ikE China Feed Industry Information Network - based on feed, serving animal husbandry
