An Assessment Of Young Cattle Behaviour And Welfare In A Virtual Fencing System, C. Holohan, A. Gordon, R. Palme, S. Buijs, F. Lively
IGC Proceedings (1993-2023)
Virtual fencing is a novel technology which uses a combination of audio and electrical stimuli to contain grazing livestock within a GPS boundary. There are however some concerns around the use of such a technology and its potential effects on the behaviour and welfare of animals. To investigate this, 64 dairy-origin calves were assigned to one of two treatments in a randomised complete block design, with 4 groups of 8 calves per treatment. The two treatments were virtual fencing (VF) and electric fencing (EF). The experimental period lasted 31 days in total, consisting of a 10 day training period and …
