Evaluating Milk Peak and Persistency Using DHIA Data Part 4

Aug 05, 2025

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.

Video: The Next Pork Disease Outbreak? How Biosecurity Can Stop It Before It Starts!

The threat of disease outbreaks remains one of the biggest challenges facing pork producers across North America. At the World Pork Expo, I spoke with Rob Hannam, CEO of Farm Health Guardian, to discuss why biosecurity is more critical than ever and how innovative technology is helping producers reduce risk before disease reaches the farm.
In this interview, Rob explains how Farm Health Guardian's advanced biosecurity platform helps pork operations monitor and manage visitor access, track potential disease exposure pathways, and strengthen on-farm biosecurity protocols. With recent outbreaks of diseases such as ASF, PRRS, PED and others continuing to impact global pork production and ongoing concerns surrounding the spread of endemic diseases, proactive prevention measures have become essential for protecting herd health and business continuity.
Learn how digital biosecurity tools can help producers identify risks, improve compliance, and create stronger defenses against costly disease outbreaks. Discover why leading pork operations are adopting technology-driven biosecurity solutions to safeguard animals, employees, and the future of the industry.
