Lesions on a corn leaf above show the hard black raised centers of tar spot lesions. Although the prolonged dryness throughout May and June appears to have slowed tar spot development thus far, morning dews, lingering fogs and rainy days provide extended periods of leaf wetness and can drive disease severity. | Photo by Marty Chilvers, MSU

Walk fields with your agronomist and talk about investing in fungicide applications to maintain plant health. We’ve observed an uptick in fiber digestibility the last year, which I think is partly attributable to improved plant health.

Take note of the tasseling date and then sit down with your calendar to circle the date range 40 to 60 days after the average tasseling date for your fields. Corn historically has been ready for silage around 45 days post tasseling; however, I’ve learned from Todd Schaumburg and other experienced agronomists that better plant health has widened this window out. More on that later. Start intensively monitoring corn with your agronomist during this 20-day window later in the season.

Producing high-quality milk is a labor intense job, yet it is a product that doesn’t receive a high payment compared to other industries. Although pay is a high motivator to stay at a job, employees are often more successful and retained at higher rates if training is offered. Training helps satisfy that need to develop and challenge their own set of skills and makes them feel a sense of ownership to the farm. In addition to training, how can the dairy industry stay competitive in this tight labor market?

When calves are born, their bodies are made up of about 80% water. As they grow, they need to consume about 10% of their bodyweight in water daily.

History likes to repeat itself. Prior to last year, the last time milk prices were great was in 2014 and we all know what followed—lackluster milk prices that challenged producers. Learning from previous financial hardships, Curtis Gerrits, a senior dairy leading specialist with Compeer Financial, outlines five points explaining why dairy producers are better positioned today vs. 2014.

Good quality forage is essential for profitable milk production. The most important factor affecting alfalfa quality is maturity at harvest. As alfalfa matures, digestibility decreases and fiber (NDF) content increases. Harvesting at the optimal maturity can be a challenge especially for first cutting when spring weather is not cooperative. Harvesting late affects the feeding value of alfalfa, but harvesting too early can result in lower yields and reduced stand life.

Steps to help minimize feed contamination on-farm and improve feed hygiene to limit a cow’s exposure to pathogens and toxins.

Intentional leadership and helping employees understand what is expected of them, why they must do things a certain way and where this job will take them in the future can assist in achieving the goals set for your dairy.

If your 2022 silage is feeding sluggish, make sure you have a solid handle on its nutritional value and variation. Sluggish feeding value could be due to lower-than-average quality or highly variable nutritional value from week to week.

Corn silage is typically included at higher levels in a lactating cow diet. It can contribute significant amounts of digestible fiber, starch, and peNDF, as well as protein and fat. Most variability is observed in the fiber and starch levels and digestibility, which impacts dry matter intake, milk yield, and components. Corn silage data compiled from Rock River Laboratory for the West (W), Midwest (MW), and East (E)US regions is summarized below.
