“…Roberts and Carrick (1943) reported experiments which indicated that a higher percentage of bran and middlings in a ration, fed to chicks from 6 to 12 weeks of age, resulted in a greater amount of feed per unit of gain than when corn replaced the wheat products. Heuser et al (1945) have also reported decreased efficiency and a slower growth rate with high fiber rations, involving bran and middlings.…”

“…Similar observations have been made by Heller and Penquite (1945) and Milne (1932)who fed the high protein diet for six to eight weeks instead of one or two weeks. Roberts and Carrick (1943) observed that chicks that grew well during the first six weeks maintained their weight advantage to twelve weeks of age over chicks receiving a lower protein starting 1 Supported in part by a grant from the Yantic Grain and Products Co., Norwich, Connecticut.…”

1. 101 Rhode Island Red × Light Sussex chickens have been made to conform to four major changes in the shape of their growth curves from hatching to twenty-four weeks, by control of their plane of nutrition. The four treatments (HH), (LH), (HL) and (LL), allowed comparisons to be made between birds of the same age, but different weights. As the main concern has been to find the essential nature rather than the precise extent of the effects produced by different planes of nutrition, the treatment differences were made as extreme as possible without allowing the rations to become unbalanced.2. Certain individual organs and tissues, the gonads, thyroid and thymus, and the combs and wattles have reacted differentially to the contrasted treatments when compared on a basis of equal body weight. All the organs, with the exception of the very early maturing eyes and heart, have reached significantly different weights on the basis of equal age. Those organs which have yielded treatment differences judged on both the basis of equal weight or equal age have all been late maturing. The results therefore indicate that the effect of treatment has been to restrict the development of the later maturing parts in the case of the low-plane birds, and to accelerate the development of these organs when the birds are reared on the high plane. The results are insensitive to any differential effects which may have been brought about in the early maturing organs, since the design of the experiment did not allow of the slaughtering of birds at equal weight but only at equal age. The means of Comparison of differences at equal weights was the less precise method of ascertaining whether the high- and low-plane regression lines of weight of part to total weight of bird differed significantly the one from the other.
