Abstract
This article studied the laying performance of 18 -60 -week -old Hyline brown laying hens in Hainan provincial tropical area through the statistical analysis of laying rate, egg weight and other production indexes. The results showed that the eggs laid by Hyline brown laying hens sharply increased since the 19th week after the first egg - laying, and reached the fastigium, then main-' tained for about 10 weeks, finally slowly decreased. The egg - laying trend in the whole process (except the 26th week) was similar with the standard egg - laying curve. It indicated that the laying performance of Hyline brown laying hens could basically meet the breed standard, and they could express their genetic proficiency when they were reared in Hainan tropical area.关键词
