Which wearable sensor could provide data to estimate the rumination time in cattle?

 Accelerometer (or a dedicated rumination sensor).

200

What type of behavioral information can be derived from analyzing accelerometer data? Mention at least one specific phenotype.

How could you estimate bodyweight or body condition score without direct physical contact with the animal?

3D/depth cameras

200

In a depth camera, each pixel stores what information?

Distance of the object from the camera
