2025 Grazing Season Update

August 20th

Hello, CARMers!

Tomorrow, we’re taking the last 28-day weights of the season and I’ll get those out as soon as I can, but even more important news, we got RAIN this weekend!!

Lately, it’s felt like there’s a dome over CPER so much appreciation for the change this week.

Review any of the previous updates here.


Let’s dive into the details

Between last week and this week, the 701x company pushed out a sesign update to their dashboard heatmaps.

I’ve added in “Last Week - New Style” and kept “Last Week - Old Style” to hopefully ease the adjustment!
