Abstract

The purpose of this study was to examine the relationship between stockperson attitude and behaviour; bird behaviour and productivity in the chicken meat industry. 2. No relationship between stockperson attitude and behaviour was observed, which is in contrast to studies in the pig and dairy industries. 3. Evidence is provided for the existence of sequential relationships between stockperson behaviour, bird fear levels and productivity in the broiler farms examined. 4. The mechanism(s) responsible for the negative relationships between fear levels and production is unclear. It is hypothesised that chronic stress or a series of acute stress responses may be the mechanism through which fear affects productivity. 5. The relationship between human behaviour, bird fear levels and productivity indicates the potential that exists to improve productivity and perhaps welfare of commercial broilers by reducing fear levels in broiler chickens.

摘要

本研究的目的是检验肉鸡行业中饲养员态度与行为、鸡的行为与生产性能之间的关系。2. 未观察到饲养员态度与行为之间的关系，这与猪和奶牛行业的研究结果相反。3. 在所研究的肉鸡场中，有证据表明饲养员行为、鸡的恐惧程度和生产性能之间存在序列关系。4. 恐惧程度与生产性能之间负相关的机制尚不清楚。据推测，慢性应激或一系列急性应激反应可能是恐惧影响生产性能的机制。5. 人类行为、鸡的恐惧程度与生产性能之间的关系表明，通过降低肉鸡的恐惧程度，有可能提高商业肉鸡的生产性能，甚至改善其福利。
