How to Read a Milk Replacer Tag
Not all milk replacers are created equally. It’s important to understand what’s in the bag to be sure the product fits the farm’s objectives when it comes to growing calves. Milk replacer tags are written in a fairly standard format, but can be somewhat confusing to end users.
Product Description
At the top of the tag, there is usually a general description of what the product contains in terms of protein and fat, as well as medications or additives. For the example below, 22 is the percent of protein, 20 is the percent fat, “BOVA” means Bovatec, “BIOMOS” is a branded additive, and “DFB” means fly control. Here are some of the more common abbreviations that you might see on a tag:
Proteins and fats:
AM – Usually means “all milk” – milk ingredients are the only protein sources.
PB – Protein blend – may contain plant, plasma, and/or egg protein sources.
P or Plasma – Blood plasma – protein source.
W&P – Wheat and plasma – protein sources.
SPC – Soy protein concentrate – protein source.
SI – Soy isolate – protein source.
CO or C-oil – Coconut oil – fat source.
Medications:
BOVA – Bovatec® (lasalocid sodium) - medication to control coccidiosis.
DX – Deccox® (decoquinate) - medication to control coccidiosis.
NT – Neo-Terramycin® (neomycin-oxytetracycline) - for treatment of scours caused by E. coli and salmonella.
Additives:
DFB – diflubenzuron, the active ingredient in ClariFly® Larvicide for feed-through fly control.

MOS – general term for non-branded mannanoligosaccharides.
EO – essential oils.
Apex – brand name of a combination of essential oils.
DFM – direct-fed microbials.

The use of antibiotics in rearing preweaned calves has changed considerably in recent decades. Many operations are relying less on antibiotics today to keep their calves healthy. Some of that reduction has been due to regulation, and some by intentional management strategy.
