John, thats strange. I actualy had less weight trouble with the 3532. I went to the 2616 to gain, and the weight and muscle went up too. But different breeds, so that might be a factor. I will grab a bag for trials to mix in, but the adult chicken, I am also very pleased with for now
. I see great stamina on it to. Very impressed with the drive in the dogs. And the tone is definatly looking more ripped.:thumbsup: Not as much breathing, just running. I really like it. I am going to drop the probiotics I am on, and see if the result stays with them after trial season is done. I think it is a combo of both working very well togeather for me. I could not be happier right now.
