Summary
Beak trimming using robotic electrocautery (ECD) or infrared beak trimming (IBT) on day-old broiler chicks has minimal impact on early growth. Skilled application of these methods does not significantly affect performance, despite minor transient weight differences observed initially.
Area of Science:
- Animal Science
- Poultry Husbandry
- Avian Welfare
Background:
- Beak trimming is a common practice in commercial broiler breeders to mitigate self-inflicted trauma.
- Evaluating the early performance impacts of different beak-trimming methods is crucial for broiler welfare and productivity.
Purpose of the Study:
- To compare the early performance of broiler chicks subjected to two robotic beak-trimming methods: electrocautery (ECD) and infrared beak trimming (IBT).
- To assess the effects of these methods against non-trimmed controls (NBT) on body weight gain during the initial weeks of life.
Main Methods:
- Two experiments were conducted using day-of-hatch Ross 708 broiler chicks.
- Chicks were divided into three groups: IBT, ECD, and NBT, with experienced personnel performing the trimming.
- Body weight and gain were monitored at various intervals up to 42 days.
Main Results:
- A minor, temporary reduction in body weight gain was noted with ECD at 14 days compared to NBT.
- IBT chicks showed a slight weight advantage at 11 days, but no significant differences in body weight or gain were observed at 21 and 42 days across all groups.
- No significant long-term performance decrements were found for either beak-trimming method.
Conclusions:
- When performed by skilled personnel on day of hatch, neither ECD nor IBT significantly impairs early broiler performance up to six weeks.
- These findings suggest that properly executed robotic beak-trimming methods do not induce substantial physical or psychogenic stress affecting growth rate.
