Milk production and the amount of rest a cow receives are related, says Peter Krawczel, graduate student at the Miner Agricultural Research Institute in Chazy, N.Y. “It appears that there is a linear relationship between resting time and milk production that indicates a gain of 3.5 pounds of milk for each hour of rest a cow receives.” In addition, Krawczel says that there is a significant linear relationship between increasing the number of stalls per cow and milk production. “Based on what we have observed in overcrowding trials, the increase in stall availability should result in increased resting time,” he says.
