Proper bird management is the key to success The use of feed additives must not replace excellent management

@Park W. Waldroup I agree too much marketing about betaine spearing methionineJohn R Wills at jrwabudhabi@gmail.com

It depends on what is low portein and the digest able lysine to formulate to and using the Ideal Protein method. Using a soy + corn as the major ingredient with a dig Lys of 1.28 plus a glycine + define set to crude protein of 22 % and using metionibe, lysine, theorinre , arginine , valinr, and isoleucine the crude protein will decrease to 20 % which is not low protein.

Currently MgO

Feather picking can be reduced by adding 1 to 2 kg of of Mg and checking the DEB balance.

One must have high quality ingredients for performance. Also L Value, L Arginine plus glycine to provide a nitrogen pool when using low crude protein diets Cheap will not work

This is the T glycine /dig Lysine ratio

George Entz I am using a Total glycine to dig lysine that would be when the dig lysine is .87 to .88

When using Ideal Protein for layers with the amino acids, lysine, methionine, value, the so one, arginine, and tryptophan then glycine must be used to equal glycine in a 16 % crude protein diet to provide enough nitrogen for non essential amino acids.
