Abstract: The crossing effect indicated,YuZhou brown eggshell layerⅡ×Ⅰ had a significient improvement on survival rate and other main production properities.The percentage of healthy day-old chicks,viability of brooding chicks,viability of rearing chicks,viability during laying period got to 99.20%,97.87%,97.12% and 93.35% seperately.The age of first egg advanced 6-9 days,72 week-old egg production was 254.20,and the feed conversion in the laying period was 2.42:1.
