smaXtec pH Plus Bolus

Here you'll learn you to initialise, calibrate and administer the smaXtec pH Plus Bolus correctly.

The smaXtec pH Plus Bolus comes with state of the art sensor technology. This is the only way to ensure reliable pH measurement in the harsh environment of the rumen over an extended period of time. The smaXtec pH Plus Bolus measures the following parameters:

  • rumen pH
  • temperature
  • activity levels

The measurement data is stored in the smaXtec pH Plus Bolus and automatically transmitted to the smaXtec Base Station or smaXtec Repeater via a radio system. The current dimensions of the smaXtec pH Plus Bolus mean it is not suitable for use in cows under the age of 18 months or weighing less than 450 kilos.

Important notice:
The smaXtec pH Plus Bolus is exclusively designed for cattle. Under no circumstances may it be used for any other animals or humans. Use of the smaXtec pH Plus Bolus is prohibited for cattle aged under 18 months or weighing less than 450 kg. If in any doubt, please consult your vet.

It must be ensured that cattle to be fitted with a smaXtec pH Plus Bolus have an empty stomach. This means that they have not eaten anything for at least 2 hours.

FIRST STEPS

Follow the steps described in the accompanying Quickstart Guide and ensure they are carried out correctly.

  1. First, please remove the label from the bottom of the smaXtec pH Plus Bolus. Next, activate the Sensor using the magnets provided (with the smaXtec Base Station). If the smaXtec pH Plus Bolus has been successfully activated, the LED on the bottom of the smaXtec pH Plus Bolus flashes briefly every 0.5 seconds. Please note the correct positioning of the magnets as indicated in the Quickstart Guide.
  2. Pour the buffer solution pH 7.00 into a narrow container (please note minimum filling level) and remove the sponge from the sensor tip. Then place the smaXtec pH Plus Bolus into the container sensor head first and gently shake it. Calibration of the smaXtec pH Plus Bolus takes at least 5 minutes. During this time the LED starts to repeatedly flash three times in succession.
  3. If calibration has been successful, the LED flashes every two seconds for a period of 30 minutes. If calibration fails, the LED flashes very rapidly (every 100 milliseconds) for a period of 30 minutes. If this is the case, please contact customer support.
  4. After successful initialisation the smaXtec pH Plus Bolus can be inserted using the smaXtec Sensor Applicator. Following selection of a suitable animal, the animal identification details should be entered in the list provided next to the serial number of the smaXtec Sensors.
  5. Activation in smaXtec Messenger by clicking on the + symbol on the right of the menu option “Animals”: activation of sensors is required to ensure the sensor is correctly assigned to an organisation in smaXtec Messenger.
  6. After successful installation of the read-out device the measurement data from the smaXtec pH Plus Bolus can be accessed in smaXtec Messenger within approximately 30 minutes.

BALLING GUN

Use a balling gun to insert the smaXtec pH Plus Bolus into the animal’s maw. To do this you may wish to use a balling gun with an inside diameter of 35 mm. This can be ordered either from us or directly from the manufacturer.

INSERTION PROCEDURE

First insert the smaXtec pH Plus Bolus into the balling gun, with the sensor tip at the head. Push the smaXtec pH Plus 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 Plus 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 Plus Bolus. The front end of the applicator must reach beyond the base of the tongue before the smaXtec pH Plus Bolus is released. Please ensure that the cow does not eat anything for at least two hours prior to administration of the smaXtec pH Plus Bolus. It is therefore preferable to administer the smaXtec pH Plus Bolus in the morning before the first feed as otherwise there is a danger that the smaXtec pH Plus Bolus can become blocked as it drops down into the reticulum.

Warning:
After insertion the smaXtec pH Plus Bolus needs to settle on the floor of the reticulum as quickly as possible. For this reason, the fibrous material in the foregut-fermenting digestive system should not be too dense, i.e. the cow should not have recently eaten any food. It is therefore of the utmost importance that your animal has an empty stomach when the smaXtec pH Plus Bolus is administered. Should the sensor tip become filled with food particles immediately after insertion this can cause the sensor tip to become blocked a few days later thereby disrupting pH measurement.
