Nutritive value of two strains of Canadian utility wheat, Glenlea and Pitic 62, was compared with those of Canadian No. 1 feed barley and of American yellow corn by feeding these cereals to laying hens.Crude protein in Canadian utility wheats, i. e., Glenlea and Pitic 62, was 15, 27 and 14.94%, respectivly, which was higher than that in Canadian No. 1 feed barley and yellow corn. Total digestible nutrients in Pitic 62 wheat and Canadian No. 1 feed barley was almost identical, being about 75%, but that of Glendea wheat was higher than those of them and almost equal to that of yellow corn, being 79.6%.No significant difference in egg production, egg weight, feed intake and feed conversion (feed/egg) was observed among the hene fed one of four cereals on iso-caloric and iso-nitrogenous basis.Yolk color of the eggs laid by the hens fed wheats and barley was between 5-6 by Roche color fan, which was significantly lower than 8 of the egg yolk laid by the hens fed yellow corn.
