The Use of Cockerel and Pullet Chicks in the Determination of the Gross Value of Protein Supplements
Year: 1943
Type: article
Abstract: CONSIDERABLE work has been done at this station in the determination of the relative nutritive value of protein supplements when incorporated in the poultry ration. Heiman, Carver, and Cook (1939) described a method by which the gross value of protein supplements could be determined in relation to casein. This method is flexible in that it permits the compounding of cereal basal mixtures to correspond with a wide variety of diets in use throughout the country. Robertson, Carver, and Cook (1940) reported the gross values, obtained by this method, of a number of commonly used protein supplements when fed alone or in combination. In these determinations, cockerel chicks have been used in order to eliminate possible differences due to an unequal sex ratio in the experimental groups. In addition, the relatively low cost of the cockerels has made possible the use of a large number of chicks during the preliminary period . . .
