Great research by Nigel Cook from the University of Wisconsin – Madison.
Notice how sand bedding leads to almost two hours more lying time!
This is what Nigel Cook says about this results:
The reason for this is two-fold. First, there are on average 42% fewer lame cows in sand-bedded freestall herds (Cook, 2003, Cook et al., 2004, Espejo et al., 2006); secondly, lame cows stand for longer in mattress stalls compared to sand stalls. We believe that the main reason for this is due to the difficulties lame cows have rising and lying down on a firm surface (Cook and Nordlund, In Press).
The table below shows lying time among 208 cows.
