Important note

The smaXtec pH Bolus SX.2 is exclusively designed for cattle. Under no circumstances may it be used for any other animals or humans. The minimum body weight of cows receiving a bolus is 450 kg when administered by trained staff (approximately 18 months for Holstein cows) and 300 kg when administered under veterinary supervision. If in any doubt, please consult your vet.
After administration, smaXtec boluses need to settle on the bottom of the reticulum as quickly as possible. For this reason, it is important to ensure that the fibrous material in the rumen is not too dense. Therefore, cows should not eat right before bolus application.

Bolus does not flash?

Bolus does not flash?

If the light does not flash, check if you are within the read-out range of the smaXtec Base Station SX.2 and repeat the process once or twice. If the bolus still does not show the correct blinking pattern, contact the smaXtec Customer Support Team and do not administer the bolus.

Details administration process

First insert the smaXtec pH Bolus into the bolus applicator, with the sensor tip at the head. Push the smaXtec pH Bolus into the applicator in such a way that the sensor tip comes to rest at the far end of the applicator. Please ensure that the push rod of the applicator is kept flat – the push rod should not press directly on the sensor tip. This ensures that the smaXtec pH Bolus is positioned sensor tip first in the cow’s stomach. With the cow’s head and neck angled in an extended and straightened position you can now administer the smaXtec pH Bolus. The front end of the applicator must reach beyond the base of the tongue before the smaXtec pH Bolus is released. Please ensure that the cow does not eat anything for at least two hours prior to administration of the smaXtec pH Bolus. It is therefore preferable to administer the smaXtec pH Bolus in the morning before the first feed as otherwise there is a danger that the smaXtec pH Bolus can become blocked as it drops down into the reticulum.

Can smaXtec pH Boluses be initialised first and administered at a later point in time?

Yes, but make sure the smaXtec pH Boluses are kept in pH7 buffer solution until administration. You should administer them within 4 hours.
No. We do not recommend reusing smaXtec pH Boluses in other animal for reasons of biosecurity. Furthermore, the boluses are not designed for repeated use. If you administer a bolus to another animal we cannot assume any guarantee for correct measurement because of the mechanical influences and change of medium (rumen/air/rumen). This is also applies for cows with rumen fistulas.
We recommend using the smaXtec pH Bolus in 6-10% of the herd. The other animals receive a smaXtec Classic Bolus for health monitoring as well as heat and calving detection.
The pH Bolus measures the pH value in the reticulum for a period of 150 days. The other data collected (inner body temperature, activity levels and rumination) are measured as with the Classic Bolus SX.2 over the entire lifetime of the bolus (approx. 5 years).
