Lying time is affected by factors such as proper stocking density, specific stall dimensions, feed time management and comfortable, compressible bedding that encourages increased lying times while still keeping the incidence of mastitis low. Lying times are indicators of stress because cows that spend longer than normal periods standing have more stressors in their environment, while cows that spend most of their day lying down and ruminating are more comfortable. Increased lying times in dairy cattle increases milk yield and profit.
