Effects of the Wood Vinegar Compound on Hatchability of Breeder

Abstract

The experiments were conducted with breeder to determine the effects of the wood vinegar compound (NEKKARICH®, Miyazaki Midori Seiyaku Co., Ltd.) on hatchability. The compound, prepared by adhering wood vinegar to amorphous carbon (1:4), was added to the diet at levels of 0%, 1.0% or 1.5%. In experiment 1, hatchability of total eggs set for broiler breeder for trial period of 15 months or 5 months were compared with that for pre-trial period of 5 months in each farm. Experiment 2 was carried out for 10 weeks after 46 weeks of age to determine the effects of feeding wood vinegar compound. In experiment 3, hatchability for egg type breeder for trial period of 5 weeks after 39 weeks of age were compared with that for pretrial period of 5 weeks
In experiment 1, hatchability of total eggs set was significantly (P<.005) higher in the trial period, than in the pretrial period. In experiment 2, hatchability of total eggs set was significantly (P<.005) higher in the trial group than in the control group. In experinent 3, fertility, hatchability of fertile eggs and hatchability of total eggs set of the trial period were improved significanty (P<.05) in comparison with those of the pretrial period.
Thus it is assumed that the wood vinegar compound serves for the improvement of hatchability in breeder.
