Feeding dairy cows sodium bicarbonate (bicarb) is an effective strategy for improving rumen function, increasing milk production and preventing milk fat depression. Furthermore, it helps maintain rumen health by preventing acidosis.
Sodium bicarbonate is commonly added to full dairy diets, which typically consist of silage and concentrates. When combined with magnesium oxide, this boosts dry matter intake while helping prevent milk fat depression.

Effect on Rumen Function
Feeding sodium bicarbonate to dairy cows improves their rumen function and can be an effective method for increasing milk yield. Furthermore, it assists with nutrient management while cutting costs down.
The rumen is a dynamic ecosystem with a diverse microbial population composed of bacteria, protozoa and fungi. These microbes break down insoluble carbohydrates and proteins for energy production while stabilizing fermentation end products.
Methane-producing bacteria are an integral element of the rumen microbiome. They convert carbon dioxide with hydrogen gas to methane, which then gets utilized by other microbes for energy production. This helps the rumen maintain a low hydrogen concentration.
Studies have demonstrated that feeding sodium bicarbonate to dairy cows improved rumen pH, DMI, milk fat percentage and yield. Furthermore, the buffer reduced lactic acid levels.
The rumen is a complex ecosystem that must be carefully managed to meet both the needs of cattle and microbes within it. To do this effectively, an understanding of rumen function as well as sound feeding management practices and cost control must be developed.
Effect on Milk Production
Sodium bicarbonate is an organic buffer that can be added to dairy diets to help regulate pH levels. Doing so helps control ammonia production – essential for milk production.
Studies have demonstrated that feeding cows a diet supplemented with sodium bicarbonate can increase milk production. One such study showed an increase of approximately 5% in milk production.
Additionally, cattle fed a bicarbonate diet had higher feed intake. Furthermore, their concentration of volatile fatty acids was higher as well.
This was due to increased feed intake and improved rumen function caused by sodium bicarbonate supplementation.
Sodium bicarbonate has been demonstrated as a beneficial additive in rumen function and can be added to dairy diets at a dosage of 1.5%. This cost-effective method offers improved feed efficiency and milk production for dairy cows.
Effect on Feed Efficiency
Feed efficiency is the ability to meet an animal’s nutritional needs with the available amount of feed. It differs from ration balance in that it takes into account nutrients such as carbohydrates, fats, proteins, minerals, vitamins, water and fiber.
Dairy cows require an adequate supply of effective fiber in their diet to form a mat for rumen microbial activity and promote motility. Low levels of this beneficial fiber may result in decreased pH levels within the rumen.
To help maintain rumen acidity, dietary buffers such as sodium bicarbonate are often utilized. They may be particularly helpful in rations that include high moisture corn or silage and forages with low fiber content.
Formulating rations requires careful consideration of their nutrient balance and digestibility. A poorly balanced ration may lead to lower milk production and more cases of displaced abomasum. Furthermore, it’s wise to evaluate the quality of feeds and forages used in your formula for protein, carbohydrate and amino acid quality balance.
Effect on Manure Quality
Addition of a high quality rumen buffer supplement, such as sodium bicarbonate, to dairy cows’ diet is an economical and efficient way to improve rumen function and maximize milk production. This supplement helps create a healthy environment in the rumen that allows feed digestion at optimal rates and can prevent various metabolic diseases like rumen acidosis, intestinal infections, and mammary cancer.
Sodium bicarbonate has an alkaline pH, making it the ideal buffer to neutralize acid produced by microbes in the rumen. This promotes fiber digestion and dry matter intake more easily in the rumen.
Studies have suggested that providing sodium bicarbonate to cows increases gas production, keeps rumen pH constant for extended periods, and enhances milk production. Furthermore, adding this supplement into their diet helps them produce more microbial proteins and volatile fatty acids (VFA) for energy production.
