EVALUATING HERD PERFORMANCE BY PARITY AND STAGE OF LACTATION
Robot herds are unique in that there are management changes built into the system for different stages of lactation. In most parlor herds, once cows leave the fresh pen, they stay in the same pen, get milked the same number of times, and eat the same ration throughout the lactation. Robotic milking systems can be set to adjust the milking frequency and pellet feeding according to milk production and stage of lactation. It makes sense to group data by lactation number and stag

HOW LONG WAS SHE DRY? AND WHAT IT MEANS FOR ROBOTIC MILKING
How long does a cow need to be dry? Everyone has a slightly different idea. Most people agree that a cow should have a dry period between 40 and 60 days. Research consistently shows that second lactation cows will produce more milk and have lower cell counts with a 55-to-60-day dry period. Older cows with longer calving intervals can maintain productivity with shorter dry periods. Too long can be as bad as too short. Long or short dry periods may result in more days open in s

SHE JUST STOPPED COMING TO THE ROBOT
In general, we expect cows to be more persistent in robot barns than in conventional milking. Heifers tend to start their lactations more slowly than in parlors but can maintain near-peak production well beyond 200 days in milk. Getting high producers to dry off at the end of lactation is a more frequent concern in robot barns than in conventional barns. But, as Mark Twain said, “All generalizations are false, including this one.” Some cows are less persistent in robot barns.

KEEP COWS COMFORTABLE TO KEEP THEM COMING TO THE ROBOT
Cow comfort gets a lot more attention now than it did in the days when I milked in a tie stall barn. And it should. Research shows that cows will prioritize lying time over eating time. Research also shows that more blood moves through the udder when a cow is lying down, facilitating more milk production. I find it ironic that we thought we were giving our cows the very best with deep straw bedding over a rubber mat in a spacious tie stall. Today’s freestall barns give us so

GIVE YOUR HEIFERS A STRONG START
Last summer I participated in a tour at 4 Cubs Farm near Grantsburg, Wisconsin. 4 Cubs is a 16-unit Lely barn. It is owned by Gary, Cris, and Ben Peterson. Nathan Brandt is the dairy herd manager. There are a lot of things to be impressed with at 4 Cubs, but what stuck in my mind was the strategy for starting fresh cows and training heifers. I checked back with Nathan a few weeks ago because a Cow Corner customer was considering using a fresh pen.

COW CORNER NEW YEAR’S RESOLUTIONS FOR ROBOTIC MILKING
Social media and news outlets are bursting with ideas for New Year’s resolutions and strategies to keep them. There are tips for everything from saving money to losing weight or giving up a bad habit. Here are some good robotic milking habits that you could consider starting for the new year. And, Cow Corner can have your back if you need help keeping them.

MY NEW ROBOTIC MILKING "COMPARISON FARM"
Dairy cattle judges talk about the ideal cow they picture in their minds as their standard for comparison. Why not have a robotic milking comparison farm? I have shared a lot of ideas about robotic dairying, and I have visited a lot of farms that execute many of those ideas extremely well. On my last trip to Canada, I visited Shamrock Dairy, at Panoka, Alberta. and it is has become my standard for comparison. They combine top notch cow comfort and bunk management to make thei

ASSIGNING MILKING PERMISSION TO DIFFERENT GROUPS OF COWS
One of the advantages of robotic milking systems is the opportunity to customize a milking schedule according to each cow’s age, production, and stage of lactation. The right milking frequency maximizes the cow’s production and comfort, and the robot’s efficiency.

IN ROBOTIC MILKING, FEED THEM LIKE STEERS
Many sources, including the Cow Corner blog, advocate feeding dairy cows so that 5% of their feed remains to be removed each day before fresh feed is delivered to the bunk – 5% refusals. Research suggests that feeding for 6% refused feed results in 50 minutes more eating time than feeding for 3% refused feed. More eating time can mean more dry matter intake. More dry matter intake can mean more milk production. The last pound of dry matter intake just might be the most profit

DRYING OFF COWS IN ROBOTS
Historically, abruptly discontinuing milking was the most common way to start the dry period. There were a few who milked the cow again a week later before administering dry treatment. Some milked once a day for a week. In tie stall barns we could take the concentrates away, and some even disabled the drinking cups. But frankly, drying off cows that milked 30 pounds per day was not that difficult. Times have changed. It is not uncommon for cows to finish their lactations at w

WHICH COWS ARE EARNING THEIR TIME IN THE ROBOT?
I have spent many hours, in many different farm offices, discussing the fate of top producing cows that take too much time in the robot. Maybe they dance and kick so attachment takes longer, or maybe their teats restrict milk flow. If they take twice as long as other cows, they need to produce a lot more milk than other cows to earn their time. You can balance production, speed, and behavior, with a weighted index, much like the genetic indexes for TPI or Net Merit.

HOW BORED ARE YOUR COWS?
Recently, customers have been asking about day-to-day and seasonal variation in their robot barns. They want to know why production, visits, and cow flow can’t be more consistent. In normal day-to-day operation, the five things most likely to change are environment, cows, feed, machines, and people. Each of those can affect how much cows eat, how much they rest, and in a robot barn, how often they are milked. The more consistent we can keep these five, the more bored our cows

WAYS TO INCREASE MILKINGS/ROBOT

CURING ALLELOMIMETIC COWS
Many dairy publications will have features in the coming weeks about the new products they saw and the new things they learned at World Dairy Expo. Since Cow Corner, and the Cow Corner concept are relatively new, many of the people who stopped by my booth began by asking, “So what does Cow Corner do?” I never actually explained it this way, but Cow Corner spends a lot of time curing allelomimetic cows. I think that cure is new to Expo.

PREPARING YOUR TEAM FOR ROBOTIC MILKING
Cows, buildings and equipment get a lot of attention when a farm is getting ready to transition to robotic milking. It’s a big change for the cows, and milking can’t start until the roof is on the building and the robots are plumbed and wired in. With everything going on, it’s easy to forget that there are big changes in store for people too. The whole team needs to work together so everyone can adjust to new roles. Here are a few examples.
