TL;DR: Evidence that non-amino acid sources of nitrogen can partially replace dietary protein for the laying hen is presented and egg formation per se would not be expected to benefit as the ratio of essential: non-essential amino acids is small.

TL;DR: The improved production of to-day's laying hen has placed additional stress for egg shell formation on the bird with the net result that a continuation or an accentuation of the egg shell quality problem exists.

TL;DR: The present study was undertaken to gain additional information on the nutritive value of rapeseed meal to laying hens and to indicate a difference in strain of bird with respect to “toxicity.”

TL;DR: Jensen and Saxena (1963) have reviewed much of the work which has been reported on the feeding value of raw soybeans for poultry and reported that satisfactory egg production can be obtained by the use ofRaw soybeans to replace soybean meal in the diet of the laying hen.

TL;DR: By and large the reports indicate that relatively high levels of rapeseed meal can be substituted for soybean meal for most classes of poultry.
