Monensin 200

A practical way to improve rumen function and herd health.

Why use Monensin 200?

Monensin is a proven additive that supports efficient rumen function and herd health. By improving how feed is converted into energy, it helps reduce the risk of ketosis and provides consistent support against bloat. It’s a straightforward, cost-effective tool that delivers reliable results on-farm. used to reduce the risk of ketosis in dairy cattle.

Support against ketosis

Cows are at greatest risk of ketosis in early lactation when energy demands rise sharply. Monensin 200 helps maintain better energy balance in the cow, lowering the risk of ketosis and supporting faster recovery and overall herd health. It also reduces the risk of coccidiosis in young cattle.

Managing bloat

Bloat is a constant concern in many systems. A daily dose of just 300mg per cow has been shown to reduce the occurrence and symptoms of bloat, helping to keep cows comfortable and performing well.

Built for ease of use

  • Cost-effective: At around 2.2 cents per 300mg dose, Monensin 200 is one of the most affordable ways to support rumen function.
  • Quality assured: Manufactured in a leading facility under strict standards, giving you confidence in every batch.
  • Consistent blending: Produced as uniform micro prills for easy handling, reliable flow, and reduced dust. With proper mixing, it distributes evenly through the feed, lowering the risk of hotspots.

The Agvance difference

What the research shows

  • A controlled dairy cow study found that monensin supplementation reduced the incidence of subclinical ketosis in early lactation, supporting its use as a nutritional tool to help manage transition-cow energy balance and ketone risk after calving. (DOI: 10.3168/jds.S0022-0302(98)75846-1
  • A transition-cow study found that monensin changed metabolic indicators and feeding behaviour around calving, with results consistent with improved energy metabolism during the transition period, supporting its role in managing fresh-cow metabolic pressure. (DOI: 10.3168/jds.2011-4744
  • A meta-analysis of lactating dairy cattle studies found that monensin use was associated with increased milk yield and improved milk production efficiency, while dry matter intake fell slightly on average, showing how monensin can shift feed-use responses in ways that favour production efficiency. (DOI: 10.3168/jds.2007-0608
Limits

These studies assess monensin use in dairy cows, including effects on ketosis risk, transition-cow metabolism, feeding behaviour, milk yield and production efficiency, not the product Monensin 200 itself, its exact formulation, prill characteristics, blending system, or on-farm feeding programme. 

Study details and links

What was tested

Research relevant to Monensin, including a controlled dairy cow study on subclinical ketosis prevention, a transition-cow study on metabolic parameters, feeding behaviour and productivity, and a meta-analysis of lactating dairy cattle studies examining production responses to monensin.

Subclinical ketosis incidence in early lactation, metabolic and feeding responses in transition cows, and milk yield, dry matter intake and milk production efficiency across lactating dairy cow studies. 

  • The evidence supports the broader use of monensin in dairy cow nutrition for transition and lactation management, rather than proving the performance of Monensin 200 as a branded product on its own. 
  • Results can vary with stage of lactation, diet composition, forage-to-concentrate ratio, baseline ketosis risk, feeding rate, management, and the exact monensin delivery method and inclusion rate used.
