Salt, Molasses, Carbohydrates, Bypass Protein - The Facts
While many products on the market are bulked up with salt, molasses, bypass protein, and carbohydrates, we focus solely on what truly matters — minerals, particularly the most critical ones calcium and magnesium, which play a vital role in supporting animal health, productivity, and performance.
Calcium and magnesium deficiencies, account for the majority of metabolic livestock disorders, in southern Australia. Ad lib feeding of these minerals in the correct ratios, will significantly reduce these issues.

Salt (Sodium) — The Facts
Salt, which provides sodium (Na), is an essential mineral required for normal bodily function in livestock, playing a key role in nerve function, fluid balance, and muscle contractions. While sodium is a critical nutrient, its inclusion in supplements must be carefully managed.
Salt is commonly used as an intake regulator and palatability enhancer in mineral supplements. At moderate levels, it can act as an effective attractant, encouraging animals to consume the supplement. However, when levels exceed 25%, salt begins to have the opposite effect, limiting intake and potentially reducing the animal’s ability to consume the required levels of more important nutrients like calcium, magnesium and trace elements.
At Rods Livestock Nutrition, we don’t rely on salt as a filler just as an essential mineral and intake controller.
Molasses & Carbohydrates/Sugar — The Facts
Molasses, glycerol and sugar, often listed as carbohydrates, are commonly added to livestock supplements to boost palatability and drive intake. Some brands promote these ingredients as energy sources, but when consumed at recommended rates and without adequate nitrogen, their contribution to daily energy needs is negligible. As shown in the table below, blocks containing over 50% of these ingredients deliver less than 1% of a lactating ewe’s daily energy requirement (28 MJ), and less than 1% for a lactating cow (110 MJ).
These ingredients, which we refer to as fillers, often make up more than half the product, leaving limited space for critical macro minerals. We’ve worked with leading nutritionists to improve palatability without overloading on molasses, glycerol or sugar. This allows our products to contain the minerals required for livestock to support performance, health and production outcomes.
If livestock are energy-deficient, the solution is quality feed, not a sweetened supplement.
Bypass Protein (True Protein) — The Facts
Bypass protein is a valuable component of livestock nutrition. Unlike other proteins, bypass protein is not degraded in the rumen, allowing it to pass through to the small intestine, where it is absorbed directly by the animal. This makes it less susceptible to microbial breakdown and ensures animals receive the essential amino acids they need for growth, muscle development, and milk production.
While bypass protein is vital, the most cost-effective way to supply dietary protein, when there is a significant protein shortfall is through feed types not through mineral supplements.
The below table illustrates why Bypass Protein, Molasses & Carbohydrates in supplements are ineffective and expensive.
