METHODS FOR BALANCE EXPERIMENTS FOR GEESE, METABOLIZABLE ENERGY AND TRUE AMINO ACID DIGESTIBILITY OF THE MOST IMPORTANT FOR GEESE FEEDSTUFFS

Abstract

A review of the methods for balanced experiments for establishing of the metabolizable energy and the amino acids digestibility for waterfowl has been made. Systemizing the former experience in this fi eld, the author submits some innovations, regarding to the adaptation of the methods for experiments with geese. The results for metabolizable energy and true digestibility coeffi cients of some basic for the feeding of geese forages (established using the adapted methods) are given. A using of specifi ed for the different birds data for the nutritive values of the forages has been recommended. The offered innovations could be used for further efforts for establishing of standardizing methods for balanced experiments with waterfowl.
