We feed a second cutting baleage bale twice a week with 2 to 3 first cutting dry bales. We spread half of the baleage bale on the ground in 4 or 5 piles and the rest of the bale in a feeder, usually on what left of a first cutting hay. This gives all the cows a chance to get some. First cutting bales go in the feeders except for outside lay that goes on the ground for bedding. They usually clean up the baleage in about the first 4-6 hours. This gives the cows a good amount of protein with a mix of hay, but not overloading them by giving all baleage. Our first cutting hay is usually very good quality with Timothy, orchard grass, with some alfalfa or clover.
We've notice that if you have baleage that was wrapped at the very high end of moisture content and is "wet" when you unwrap it, the cows loose interest in it as it dries out. So if you put too much out at once and spread it out, you will get more waste.
