Egg laying is an important reproductive behavior of female poultry. Here, we investigated the and clutch traits different goose breeds, specifically, Zhedong white geese (Anser cygnoides), Sichuan cygnoides) Hungarian anser). A total 108 in their first year were selected. Their rhythm was monitored daily by video cameras during egg-laying period. The results showed that prenatal included nest hunting, site selection nesting, as well crouching, anal contraction until oviposition postnatal resting. There some differences times among 3 breeds. Approximately 70% eggs laid between 03:00 12:00 geese, while throughout day. Also, length interval differed these average lengths approximately 14.07, 12.14 19.15 days respectively. While intervals 2 peaks (39 47 h), (41, 50 53 1 peak (46 h). Moreover, there significant correlation egg yield (r = 0.951), 0.987) 0.991), Taken together, difference breeds mainly reflected time intervals, have preference short which helpful not only to understand process, but also manage scientifically improve production.
