Abstract To investigate the effect of new large-scale water-saving breeding mode of breeding geese, taking two large-scale breeding goose farms in Guangdong Province as the research object, to detect the water quality changes of bath pond and water trough under different breeding modes of the two goose farms, and the effect of such changes on the productivity of breeding geese. The results showed that the total bacterial density, Escherichia coli density and endotoxin level in the bath water were significantly higher than those in the water trough under the semi-arid breeding model(P<0.05); the total bacterial density of open-pond breeding bath water was higher than that of semi-arid breeding bath water(P<0.01), but there was no significant difference in E.coli density(P>0.05); the endotoxin content in water bath in the open-pond breeding goose farm was significantly lower than that of the semi-arid goose farm(P<0.01), and the serum endotoxin level of the former was also low. Comparing the productivity of the two goose farms, it was found that the average daily laying rate in open-pond breeding goose farm was higher than that in semi-arid goose farm(P<0.01); while no significant difference was found in fertilizing rate, dead embryo rate and hatching rate between the two goose farms(P>0.05). The results showed that goose breeding enterprises could try to use semi-arid breeding model instead of the open-pond breeding.
