Electrolyte Advanced

*Two bases, deliberately. The proximate guarantees are per the powder as sold; the electrolytes are per litre of prepared solution, because the litre is the unit anyone handles at the calf. The proximates previously read 0.4% protein — that figure was per litre of the LIQUID this product used to be, and it did not survive the change to a powder. Crude protein here is glycine: Kjeldahl counts a free amino acid as protein.

Preparing and offering

*Prepared fresh for each feeding. This is a nutritional product supplying fluid and electrolytes; a calf that is down, will not stand or will not suck needs a veterinarian, not a bucket.

Feed twice daily using a standard 8 oz measuring cup, adjusting to maintain ideal body condition. Introduce gradually, mixing with the current food. Fresh drinking water at all times.

Dextrose, sodium acetate, glycine, potassium acetate, maltodextrin, sodium chloride, calcium lactate, magnesium sulfate, citric acid, silicon dioxide.

*Descending order by weight, using AAFCO ingredient names. Not truncated behind a “read more” — the list is the product.

• Four variables govern this formula and cannot be optimised independently: osmolality, sodium concentration, alkalinising capacity and energy. The last three act through osmolality on abomasal emptying rate, and therefore on how fast sodium reaches the small intestine.
• The alkalinising agent is deliberately not maximised, and that is the specification decision a competitor will attack. Raising it from 150 to 300 mmol/L slowed abomasal emptying — working against the resuscitation it was added to support. Bicarbonate raised plasma bicarbonate faster, 300 mmol/L acetate raised plasma volume more, and across four solutions no clinically important difference in resuscitative response was found. The optimum is intermediate and has to be chosen.
• The 123 mmol/L figure is ACETATE, and the distinction matters because lactate and citrate are alkalinising too. Counting them, total metabolisable base is about 130 mEq/L — still far below the 150–300 range where emptying slowed, but the number quoted must name the agent rather than imply it is the total. A competitor comparing total base against our stated 123 would be comparing the wrong two things.
• Calcium lactate and citric acid sit at the same 1.5 mmol/L, and citrate binds calcium roughly one for one. The calcium is therefore a formulation component and not a nutritionally meaningful calcium source, so no calcium claim is available. Specify the L-isomer of calcium lactate: D-lactate is the metabolite implicated in the acidaemia of the scouring calf, and a racemic salt would add a little of exactly the thing the product exists to correct.
• Glucose and glycine are both present because sodium absorption is co-transport-dependent. Neither is there for energy alone.
• One piece of category folklore was overturned and is worth knowing: a low-bicarbonate solution added to milk did not affect clotting in vivo. That licenses one formulation, not the practice generally.
• Worth stating plainly: electrolyte water given to heat-stressed cows shifted hydration and acid-base markers and changed nothing in bodyweight, condition, calf birth weight, respiration rate or body temperature. The physiology moves; the outcomes do not automatically follow it.

*These describe formulation decisions. They are not health claims, and no effect on any condition is asserted or implied.
