摘　　要：对罗斯AB、罗斯CD、海赛克斯AB、海赛克斯CD和京白Ⅲ系5个蛋鸡品系的生产性能进行了测定。研究结果表明,5个系的开产日龄分别为172.55、159.66、168.17、159.10和202d;开产蛋重为42.42、42.35、44.37、40.66和41.65g;开产体重为1681.00、1585.56、1668.74、1606.53和1413.04g;72周龄平均产蛋量为234.08、249.83、225.09、222.98和218.36枚;平均蛋重为59.87、59.23、58.88、56.71和57.06g;产蛋期存活率相应为92.70、95.15、78.83、78.85和83.00％。本次试验结果,为“豫州褐壳蛋鸡”的培育提供了数据。The production performance of five varieties layer—Ross AB,Ross CD, Hisex AB. Hisex CD and Beijing White Ⅲ was tested. The various respective results of the five varieties are as follows, laying start age (d): 172.55, 159.66, 168.17, 159.10 and 202, egg weight at laying start (g): 45.42, 42.35, 44.37, 40.66 and 41.65. body weight at laying start (g): 1681.00, 1585.56, 1668.74, 1606.53 and 1413.04; average egg yield (to 72 weeks): 234.08, 249.83, 225.09, 222.98 and 218.36; average egg weight(g): 59.87, 59.23, 58.88, 56.71 and 57.06; Livability in laying period (%): 92.70, 95.15, 78.83, 78.85 and 83.00. The experiment provides basic data for the breeding of 'Yuzhou Brown Shell Layer.'
