SUMMARY
  • The modern layer bird has the potential to be high performing which is indicative of a healthy gut.
  • Layers fed Orego-Stim had a 5.8% increase in saleable eggs (up to 72 week of lay) compared with the control.
  • Extending the productive lifetime of laying hens can have a large benefit to the bottom line, ROI calculated as 80p per hen per day.
  • Orego-Stim has been shown to significantly reduce second quality eggs (Chiong, 2000).

 

BACKGROUND
  • Small increases in the daily performance of laying birds can have large benefits over the whole laying period.
  • Extending the productive lifetime of laying hens can have a large benefit to the bottom line ROI calculated as 80p per hen per day.

 

TRIAL DESIGN

Anpario have conducted a commercial study with ISA Brown layer hens at 67 weeks of age. 6529 hens were divided into two groups and either fed the basal control diet or with 250g/MT Orego-Stim following a two week adaptation period. The group with the lowest production was chosen to be the Orego-Stim group with 68.5% compared to the control group of 74.4% daily production performance respectively. Daily egg production was monitored for 5 weeks with Orego-Stim being fed from 69 to 71 weeks.

RESULTS
  • During the feeding period and following the Orego-Stim group were able to match and outperformed the control group by increasing the number of saleable eggs, resulting in a final average performance 5.8% higher than the control.
  • The performance curve is therefore improved the persistence of lay and demonstrates a ROI.
  • Trials have demonstrated that Orego-Stim can maintain persistence of lay when fed at 250g/MT.
