Jejunal Glucose Absorption in Selected High and Low Weight Lines of Domestic Fowl1

Patricia S. Walker, Harry P. van Krey, Jerry A. Cherry and Paul B. Siegel

Virginia Polytechnic Institute and State University, Blacksburg, VA 24061

Intestinal glucose uptake was measured in normal and dwarf chickens from lines selected for high and low body weight. Jejunal tissue rings were excised from 9-week-old chicks and incubated in a medium containing .002 M glucose. Significantly more glucose (micromoles per gram dry tissue weight) was absorbed by tissues from the low weight line when compared to tissues from the high weight line. The dwarf gene, dw, had no effect on glucose Uptake.

KEY WORDS: • glucose • absorption • small intestine
