Yes, balancing a chicken's diet is hard, and many seek to reach crude protein targets by introducing concentrated nutritional sources which are also high fat, without adjusting carb intake, with real long term health consequences for their flock.3)a, Controlling the fat levels.
I don't think so. How to feed baby chickens in confinement may be, but how to feed real grown up chickens that are free to wander where they will, definitely not.How to feed chickens is the most studied of all species regarding nutrition needs
Their nutritional needs don't change, only the methods for meeting those needs change.I don't think so. How to feed baby chickens in confinement may be, but how to feed real grown up chickens that are free to wander where they will, definitely not.
they do if they've had a cecectomy, as many birds used for nutritional studies have.Their nutritional needs don't change, only the methods for meeting those needs change.
at the end of the study - before being destroyed. Followed by inspection of villi lenght and crypt depth, among other purposes. Do they release such birds in the EU rather than euthanise?they do if they've had a cecectomy, as many birds used for nutritional studies have.
Edited to add: "The role of the avian caeca in the maintenance of gut health, fermentation of undigested nutrients, re-cycling of nitrogen from urine, and modulation of the gut microflora is not well understood."

I pointed out that the chickens that are studied are either broilers - so up to about 5 weeks old, otherwise known as chicks or baby birds - or cecectomized roosters, i.e. adult male birds that have had their ceca surgically removed or ligated before the experiments on diet began. There are even papers on what difference it makes to digestion between removal and ligation. There are even papers by the surgeon in chief of this method responding to challenges by other poultry nutritionists on the appropriateness, or otherwise, of his methods in the so-called precision fed laboratory results. eg. https://www.sciencedirect.com/science/article/pii/S1056617119323177How to feed chickens is the most studied of all species regarding nutrition needs, even more than how to feed humans, or dogs, or cats
I don't agree with it either.you claimed

especially issue 3, which compares the AA digestibility values of baby birds and incomplete roosters. Where's the laying hen figures?
Frankly, I find this work disgusting.
