Fig. 5. Feces and urine distribution by 36 lactating dairy cattle across six observation periods (five of 24 h and one of 13.5 h) on a 0.74-ha paddock. Cattle were restricted to the front half of the paddock during the first grazing period (12 h) and permitted access to the entire paddock during the second grazing period (8 h). Urine = 0.36 m² (0.68-m diameter), feces = 0.12 m² (0.39-m diameter). Concentric lines radiate at 10-m intervals from the water tank. Urine spots were flagged so they could be mapped, while feces spots remained visible for the mapping and did not need to be flagged. Therefore, feces spots were not differentiated between grazing periods because they were not marked during the observation period.
