What is When the measurement affects the object – Impact of a multi-part head/neck mounted wearable device on dairy cow behaviour, health and productivity about?

Wearable technology is increasingly used in both dairy research and commercial dairy farming. Assessment of how such wearables affect cows is of major importance to rule out reductions in welfare and productivity that would hamper commercial implementation. Furthermore, if devices intended to measure behaviour affect behaviour, data can no longer be extrapolated to a larger (unequipped) population, hampering their use as research tools. Lack of published research on this topic may cause an underestimation of effects on cows and research findings. We assessed the effects of a head/neck mounted wearable intended to capture methane and measure activity on dairy cow behaviour, health and productivity. The device consisted of a nose-piece covering the nostrils, held in place by a halter and a 4 kg neck-rig (31 × 19 × 23 cm at the widest points). We performed a 2 × 3-week cross-over trial involving 44 cows. Whereas many variables were not found to be affected, the wearable significantly (P < 0.05) affected bald spots (2.3-fold increase), social grooming (initiated: 41% decrease, received: 34% decrease) and drinking time (10% increase). Furthermore, milk yield and lactose content were sig
