Complexity of a Chick Growth Response to Egg Yolk, Animal Fat and Fish Solubles Additions to the Diet

Dietary Fat in the Nutrition of the Growing Chick

“…Thus Denton et al (1954) reported that animal fat contained an unidentified growth factor which they postulated as the same factor found in fish solubles. This conclusion was confirmed by Arscott (1956). Menge et al (1957) reported that an unidentified factor, found in the non-saponifiable portion of egg yolk fat, increased chick growth by 18 percent at 4 weeks of age.…”

Abstracts of Communications

“…These results suggest that the growth-promoting effect of the whole egg was due to the gross nutrients it supplied, and the growth-promoting effect of egg yolk on chicks observed by Denton, Lillie & Sizemore (1954), Arscott (1956) and Hopper, Scott & Johnson (1956), attributed in the last two papers to an unidentified growth factor, may also have been due to the fat and protein in the egg.…”

Factors Affecting Growth Response of Chicks to Dried Egg Yolk

“…Chicks from Red Vantress males were used in the initial experiment(s) cited in Tables 2 and 3 while chicks from White Vantress males were used in the last experiment that comprises each table. Care and management of the battery raised chicks have previously been described by Arscott (1956).…”
