Total or Partial Mixed Ration? Pros and Cons of TMR and PRM

Total or Partial Mixed Ration? Pros and Cons of TMR and PRM for your Feedlot

There are many different types of feed rations available in the farming industry. But two that have proven to be most effective at feeding animals in a feedlot situation, total mixed ration (TMR) and partial mixed ration (PMR). However, which system is right for your business?

Total Mixed Ration 

With TMR, all feed components (staple and concentrated) are mixed to make a ration. There is no concentrate supplement since this system relies on the animals foraging in order not to over-or underfeed them. Groups should be divided into several smaller groups based on their age/weight so as not to provide too much of any given food source.

Partial Mixed Ration 

The ration for PMR is designed to contain all staple components, mineral feed and a proportion of concentrated feeds based on the performance potential of their respective herds. The remaining concentrate will be allocated depending upon an animal’s current level of production via a transponder-controlled feeding station.

System Comparison

Feeding TMR is an optimal form of feeding because it provides animals with the energy and protein they need to perform. It also has a positive effect on health, as there are fewer pH fluctuations in the rumen which decreases acidosis risk. However, this does require that several performance groups have different rations for their respective requirements. If these conditions aren’t fulfilled, then TMR isn’t effective or efficient enough.

PMR is a risk in animals receiving concentrated feed via transponders, as they experience violent pH fluctuations. These intensive portions of food should be distributed throughout the day to avoid acidosis from occurring.

Another benefit of TMR is that homogeneous mixing counteracts any selection of individual feed components. Additionally, there is the option to use low-cost regional byproducts as well. This is advantageous from an economical farm management perspective. 

There’s also decreased workload and time saving with this method. Along with not having to invest in a transponder controlled concentrated feed station or similar equipment like some other methods required for their cattle feeding operation.
