抄録

Kidney ornithine transcarbamylase (EC 2.1.3.3) activities of chicks of five different breeds of chickens were compared in this study. Ornithine transcarbamylase (OTC) activities of California Gray, New Hampshire, Rhode Island Red, White Plymouth Rock and White Leghorn A line, were all within a range of 0 to 50 units, and rarely exceeded 10 units. Differences of OTC activities were slight among these five breeds, of which California Gray showed the lowest level of less than one unit. In White Leghorn B Line, extremely high activities of OTC were found, where 25% of the population showed 140 to 290 units and the remaining 75% showed 0 to 50 units. This distribution is apparently bimodal and would imply genetic control of OTC activity in the chicken.
