I've seen some variation in recommendations about protein content for broiler diets. My broilers start going to processing next week, and have had a steady diet of 20% chick grower ration and 17% finisher supplemented with kitchen scraps and whatever bugs they can catch when pastured. They'll be 2 months old on or about the 10th, and while I am very pleased with the process, I am seeing people discussing the use of rations with much higher protein contents. While I don't think I've done anything wrong, and am generally pleased with the results, I am concerned that keeping Cornish-Rocks much past 6 or 7 weeks seems to put a LOT of physical strain on the birds. Not CHF or massive deformities, but I note that over half the broiler flock has trouble walking more than a few feet or standing for appreciable periods of time. To my mind, a more rapid finish is desirable(with slower developing birds with fewer/no obvious problems being kept until they are large roasters). Would people be willing to share their approaches and how they change protein content as the birds grow? At what point do you change from starter ration to something with higher protein? How do you control Coccidiosis if you are not using medicated feed? Links to websites would be great. Thanks!
