The ETD BOLUS



 is sealed in an inert polypropylene capsule and weighted to prevent 

the bolus from being expelled from the rumen or from being passed through the digestive 
system. Powered by a sealed lithium battery, the ETD BOLUS



 has a functional lifespan 

– without attention – of approximately five years. 

Because a cow’s normal temperature can vary according to the temperature of their 
environment, the ETD BOLUS



 monitors and calculates a ‘normal reference’ 

temperature for each animal, adjusting this reference temperature according to seasonal 
and climatic changes.  

In addition to long-term health monitoring, the ETD BOLUS



 can also be used for 

veterinarian monitoring to report reactions to injections, implants or other treatments and 
can be used for ovulation monitoring (in development) to report when an animal is ready 
for artificial (or natural) insemination following the use of fertility stimulants. 

Any changes or modifications not expressly approved by CowTek, Inc for compliance 
could void your authority to use the equipment.
