What is the ideal pH range for a "close up" Holstein's urine?

The ideal pH range for a "close up" Holstein's urine being 6.0 to 6.5 is significant for several reasons related to the nutritional and health management of dairy cattle, especially during the transition period before calving. This range indicates healthy metabolic activity and suggests that the cow is effectively utilizing the dietary nutrients and maintaining proper mineral levels.

When urine pH is maintained within this range, it typically reflects a balanced diet that supports optimal rumen function and avoids issues such as acidosis, which can occur if the pH drops lower than desirable. A slightly acidic urine pH can also indicate adequate acid-base balance in the diet, which is crucial as cows are transitioning to high milk production post-calving.

Maintaining urine pH in the ideal range also plays a key role in the prevention of metabolic disorders that can affect both health and productivity. This focus on metabolic health is particularly important during the close-up period, when cows are preparing for calving and the onset of lactation.
