Using the Feed Phone
I. On animals → Check the assembly of the Axel box on the collar: the marking will be against the animal's neck; → Note the sensor number and the number of the animal on which it will be placed; → Place the collar on the narrowest part of the neck behind the ears; → Tighten the collar so that it is correctly adjusted to the morphology of the neck. NB: The Axel sensor records data for the two Services: HeatPhone (heat detection) and FeedPhone.
II. Operations on the DWS
1/ Connecting to your DWS interface → On the DWS website "dws.medria.fr" → Enter the user id (farm no.) and the password; → Click on OK.
2/ Saving the animals in DWS → Go to the tab Animals; → Click on the button + Add an animal; → Complete all the fields accurately: particularly the date of birth, the breed and the group (to be created, with a minimum of 5 animals in a group) which are determining elements for detections; → Click on Save. NB: Possibility of importing a list of animals by using the "export" and "import" buttons in the "animals" tab.
3/ Associating a sensor with an animal → Go to the tab Equipment ; → Select the required sensor (AX for Axel box); → Click on the button Create an assignment; → Select the required animal from the drop-down list; → Enter the precise date and time of the collar installation; → Click on Create an assignment. NB: This operation can also be done using the SmartDWS application. The assignment on DWS must be done within a maximum period of 5 days after installing the collars on the animals.
4/ Deleting a sensor/animal assignment → Go to the tab Equipment; → Select the row of the required sensor (AX for Axel box); → Click on the button Delete an assignment; → Click on Delete the assignment between sensor / animal. NB: The sensor/animal association is automatically deleted if the sensor is removed from the animal's neck and does not move for 2 days.
5 / Configuration of the detections and SMS alerts Detection setting FeedPhone detections are generated in the event of overruns of the thresholds for ingestion and rumination times or according to variations in these times. These parameters can be manually adjusted for each category of animal according to your experience and judgement, however a standard setting is proposed: → Go to the tab Services / FeedPhone; → Fill in the desired values; → Click on Save. Setting the sending of SMS → Go to the tab Services / FeedPhone; → For each event, select the sending method for the SMS: instant or report; → Renew the operation for each recipient; → Click on Save.
III. Interpreting data from the FeedPhone
1/ The Different alerts
2/ Consultation of information on DWS and SmartDWS On the "Home" page, the FeedPhone button gives access to the service functions: Detections, Information and Movements. The four detection functions: Group on alert, Animals on alert, Groups and Animals give access to a list of animals detected over the last 24 hours, a bar chart and a curve for each. You will find on each bar chart: the time of ingestion and rumination in minutes for the last 24h, the average over the last 7 days and the variation over 24h.
NB: A period of 9 days is required after installing the collars to be able to observe the first bar charts and curves.
3/ Specific cases Example 1: piloting the rations Can you increase production of your herd without risk of sub-acidosis? eg: 550 min By experience, we can go down to 450 min, you can, therefore, increase the energy density of the ration by reducing the fibres present in your ration (straw, hay...) or increasing the concentration. This will reduce the rumination time, but there is a margin of 100 min. NB: Any analysis must take into account the herd's homogeneity, the percentage of new calves in the group... You can also fraction the progression of corrections. Example 2: pasture system For several days, you have noted an increase in the ingestion time of your herd. We can emit a hypothesis of overgrazing (grass too short) so the animal takes time to satisfy its appetite. Example 3: animal in distress Below an example of the change in curves linked to a displaced abomasum.
