Two trials in a commercial Thai broiler farm used Orego-Stim liquid in broilers. Birds in the second trial were grown for 45 days to reach a large final bodyweight size with large breast meat for export markets.

Methods

Trial 1

Trial 2

Trial 1 used all female broilers. The experimental group used:

• Orego-Stim Liquid (OSL) from day 6 – 46 at the recommended inclusion rate.

 Trial 2 used male and female broilers. The experimental group used:

• Orego-Stim Liquid from day 0 – 9 at the recommended inclusion rate, untreated from day 10 to 14.
• Orego-Stim Liquid from day 15 – 21 at the recommended inclusion rate.
• Orego-Stim Liquid from day 22 – 45 at the recommended inclusion rate.

In both groups birds had a day length of 8 hours/day and implemented normal management with antibiotic treatment for the first 5 days and therapeutic treatment as necessary until market age. At the end of the production cycle, a range of production parameters were calculated to evaluate efficacy of Orego-Stim and return on investment.

Profit Calculations

Conclusion

In addition to the differences in application concentration and frequency of Orego-Stim Liquid, there was a problem in the first trial with ventilation in the broiler house which reduced profitability of the trial across both groups. Even though this occurred, there was still an increase in profitability in the Orego-Stim group by 33% more than the control group in the first trial and the male birds in the second trial had the same proportion of profitability increase. There was a 64% increase in profitability of the Orego-Stim group with the female birds in the second trial.

There was no condemnation data recorded for both male and female birds in the second trial. These trials have shown that a combination of increased average final body weight, improved livability, reduced FCR and reduced percentage condemnation of final carcasses upon harvest with the use of Orego-Stim accounts for greater profitability and return on investment for this broiler farmer in Thailand.
