TL;DR: HEN studies conducted at this station have shown that, under the climatic conditions of western Washington, hens will lay equally well on corn and barley diets, but barley was found to be only 82.7 percent as efficient as corn in the production of eggs.

TL;DR: Little has been reported relative to the 8–20 week nutrition of the developing pullet being raised as a potential egg producer, but it is reported that White Leghorn pullets from 12 to 20 weeks of age required no more than 12 percent protein.

TL;DR: Evidence is presented indicating that iodinated casein will help to sustain egg production of hens during the later months of the first laying year and certain of these data also indicate that the drug will tend to increase the rate of lay of birds in subsequent years beyond the first lay year.

TL;DR: The question was raised as to the effect of age at time of enzyme additions to the diet on subsequent laying house performance when chicks were known to respond in growth rate to enzyme supplementation of barley diets.

TL;DR: It is shown that the reason for differences in interval length between different birds can largely be accounted for by variations in the time the eggs remain in the uterine portion of the oviduct.
