Searching this forum, I cannot find any discussions on how to manage the ADF levels and would appreciate some input.

On page 9 Figure 1 has an excellent chart that should help. That is the start, your harvesting management is also a major contributing factor. +
Their chart tells us that harvesting at 18 day interval will result in 18% CP.
You will need the fertilizer to support a ton of hay at > 18% CP . i.e. at least 60 lbs of nitrogen.
If you believe TAMU 120 lbs would do wonders.
The other elements also must be in balance, in the crop.
So if you have enough fertilizer for rapid growth to produce ¾ ton of hay.
We are talking about compition hay not production hay.
You will have to, (Must) manage your harvesting to retain the maximum amount of leaves. It is in the leave that the good ( Low ) ADF & NDF are found. Bale that windrow as close as you can at 70% Relative humidity for a moisture level in the 18% to 20% range.
You want to rake this hay at as close to 90% relative humidity, to preserve leaves. Do this for both production as well as compition hay.
Cut the hay with a conditioner machine set to lay the hay out so wide that you have only a faint hint of where one pass is next to the other. This is also for both compition and production, and assuming you are in the humid east not the arid west.
You want a cloudless day of hot sunshine, This is to get the hay down to an average 47% moisture by sunset. This will stop respiration and loss of feed value. Now if you are in the Arid West you do not NEED the wide swath of hay, your 10% RH and 15 mph of wind will do just fine thank you.
What you want is stems that are down in the 10% moisture range and the leaves to be up close to 30% moisture at baling.
Your hay bale will be as soft as a feather bed. You will have more than 50% leaf possibly 60% leaf, and ideal is 70% leaf. ( Something you can never do with alfalfa. )
I cut at a 42 day interval and have difficulty holding the CP down to 12%. The most protein a customer will pay good money for is 12% CP grass hay, HERE, in CenTex.
Sorry this format will not support the copy and paste of the chart, you will have to look it up.
