Pre-incubation storage time and in ovo injection with maltodextrin on Pekin duck incubation parameters

ABSTRACT: The objectives of this study were to assess the effects i) pre-incubation storage time Pekin duck eggs on incubation parameters and ii) different levels in ovo injection with maltodextrin duckling weight. was divided into two experiments using hatching Cherry Valley SM2 hens egg-laying ages between 31 40 weeks. In experiment I, 8,820 subjected periods (one-seven days). For II, 120 weighing 75 85 g selected inoculated 250 µL 0.75% saline solution concentrations treatments (0%, 1.5%, 3.0%, 4.5%). relation time, stored for one day had lower hatchability rates higher mortality than longer (P < 0.05). 3.0% significantly increased weight ducklings (53.62 g) compared that by other Therefore, produced weeks life may be seven days without affecting hatchery productivity parameters. ducks improved ovoinjection solution.
