These sheep - which are wearing nappies - are taking part in a research project for the Brazilian company – Epagri, an agricultural research and rural extension company.
The researchers have fitted the sheep with microphones on their heads to monitor how much pasture is being chewed. The recorder is fitted to the white bag on the sheep’s back.
The nappies measure the weight of the excrement to discover how much grass has been ingested.
The aim is to “associate the sound of chewing with the amount of pasture ingested” according to a spokesperson, with the goal being that they can then recommend an ideal height of grassland to farmers in order to optimise maximum intake. This is the next step in grassland management.
