Abstract


A research was done to detennine the concentration and proper supplementation time of oxygen in traditional hatchery to improve the productivity of Mojosari duck at starter period. Fertile duck eggs were hatched in an oxygen—enriched environment during day 1, 2 and or 25 till hatched to test the hypothesis that prenatal oxygen supplementation treatments has separate effects on the developing embryo and day old duck. Prenatal exposure oxygen but no interaction
between oxygen supplementation and time of oxygen supplementation treatments improved hatchability. Day old duck weight and weight gain were effected by oxygen supplementation and time of O2 supplementation treatment and also their interaction. It was concluded that the highest hatchability and weight gain at starter period were resulted in the treatment of O2 supplementation for 21 % on day 1, 2 and day 25 till hatched. The highest day old duck weight was resulted in the control treatment.
