Evaluating Milk Peak and Persistency Using DHIA Data Part 4

The milk peak and persistency measures from the 202 Herd Summary or PC DART herd Management Software are dairy herd production metrics worth monitoring monthly. They give a quick overview to benchmark the herd performance changes. The peak milk is a sensitive metric, and it quickly reflects nutritional changes in the feeding program.

To improve milk peak and persistency, producers are advised to take simple management steps and efforts to focus on dry and transition periods, four weeks before and four weeks after freshening.

Management Areas to Maximize Milk Peak and Persistency

• Implement basic management strategies such as optimize dry matter intake, use feed additives to improve rumen health, improve cow comfort, evaluate body condition scores on a regular basis, and use antioxidants to increase the efficiency of immune system function. These strategies will not only increase peak milk values but will also increase the whole lactation production and improve farm profitability. 

• Review the cows’ environment and management for possible stressors such as sufficient bunk space, cow comfort, overcrowding, overall hygiene, grouping, etc.
