How do you know the poultry are eating less vs simply not liking it? Are they offered a conventional alternative taste test after a week eating the ferment?
Well, I guess it takes a little
common sense to figure that out and a good familiarity with your flock. I know what amounts my flock, or just about any dual purpose breed, will eat in a dry feed and maintain good conditioning.
I don't normally experiment with other feeding methods and have just fed dry layer mash and whole grains for many years to my flocks and have never had any issues with health or nutrition. When I tried the FF, it was with the understanding that it isn't a big stretch or any wild and new thing...fermentation of grains for livestock is as old as time. My granny used to do it for her pigs and the chickens would steal some of that feed as well. I chose to try it because feed prices are rising and my income isn't. It's been a successful venture, I might add.
Now, when I feed the FF~knowing the total feed volume in the scoop measure is actually less than when fed as dry~and they clean it up as quickly and as eagerly as they do the dry, I know they are eating less while still "liking" it. Actually, since they've grown accustomed to the FF, they really don't clean up dry feed (yes, I experimented with this) as quickly as they do the FF. More importantly, they maintain excellent condition on the amounts given, so eating less but still maintaining good body condition equals less feed for the same end result~healthy conditioning.
Then, when I have to give less actual
scoops of feed than I used to have to do when feeding dry, and get the same result, I know I am, again, feeding less feed and the birds are maintaining the same conditioning. When I am
buying less feed and less often, I know I am feeding less feed~and the birds are still fat and sassy.
It isn't hard to maintain a good ferment if you monitor smell, color, etc. That is something that comes with
experience but one will never gain experience if they do not even try.
In the end? I've never seen any feed that my chickens have not liked if they are hungry
enough. I feed once a day, so they are hungry enough each and every day. Chickens pretty much eat anything that resembles chicken feed, so the issue of their "not liking it" is a non-issue. Taste tests? Those are for humans, these are chickens. Chickens will eat
maggots out of cow pies...they just aren't that picky of eaters.
In conclusion...when my chickens maintain good body condition and good health and I am having to dish out/buy less feed, I know they are consuming less feed vs. just not liking it.
I don't think anyone is calling this a one size fits all method. One can feed whatever nutrition one likes, whatever feed you like, whatever additives, grains, etc. that you like with this method. Your feeding choice is your choice and fermenting your choice does not make it a standardized feed method. It simply just makes whatever you feed more available to a monogastric animal and also provides good probiotics for their digestive and immune system health. That doesn't adjust your method to a standard, one size fits all feeding method at all, but merely enhances what you are already feeding so that you are getting the optimal amount of nutrients from it.
It's like a take it or leave it situation...it's good info and it has benefited many but no one is going to twist anyone's arm to try it. Usually if I find something that is a good thing and has helped me along the way, I like to pass it on. YMMV
