Abstract

This study investigated the effect of plant species, month of the year, time of the day, and weather variables on hen percentage outdoor and ranging distance of Lohmann LSL Classic (LW) and Lohmann Sandy (LS) strains. Mentha piperita (M. piperita), Petroselinum crispum (P. crispum), and Medicago sativa (M. sativa) were studied. From 14 to 42 weeks of age, the number of hens outside and the distance ranged: from 0 to 3.0 m, 3.1–6.0 m, and 6.1–9.0 m from the barn were live counted at 9:00 a.m., 12:00, and 3:00 p.m. daily. Also, within the same time, the weather conditions (live observed), and the indoor and outdoor temperatures were recorded accordingly. More LW than LS hens were observed outside and more LS than LW hens ranged further than 3.0 m from the barn (p < 0.01). More hens were found in the M. sativa than in other plant treatments (p < 0.01). The percentage of hens outside and ranging distance increased at 12:00 noon, at an indoor–outdoor temperature difference of ≥ 3 °C, and in October (p < 0.01). Hen percentage on the range and ranging distance increased and decreased in cloudy and foggy weather, respectively (p < 0.01). Additionally, the interaction between strain and the month of the year, and the interaction between strain and the weather conditions affected hen percentage outdoor (p < 0.01). It was concluded that the hen percentage outdoor and ranging distance can be modulated by plant species and laying hen strain. It is crucial to consider these two aspects in further studies so that the ranging behaviors of hens can be enhanced.

影响不同品系母鸡活动范围的因素

本研究调查了植物种类、年份、时间和天气变量对 Lohmann LSL Classic（LW）和 Lohmann Sandy（LS）品系母鸡户外活动比例和活动距离的影响。研究对象包括薄荷（M. piperita）、脆片（P. crispum）和麦冬（M. sativa）。从 14 周龄到 42 周龄，每天上午 9:00、12:00 和下午 3:00，对母鸡在室外的数量和距离进行活体计数：距离鸡舍 0 至 3.0 米、3.1 至 6.0 米和 6.1 至 9.0 米。此外，在同一时间内，还记录了相应的天气状况（现场观察）和室内外温度。在室外观察到的长线母鸡数量多于长线母鸡，在距离鸡舍 3.0 米以外活动的长线母鸡数量多于长线母鸡（p < 0.01）。在 M. sativa 中发现的母鸡比在其他植物处理中发现的母鸡多（p < 0.01）。在中午 12 点、室内外温差≥ 3 °C和 10 月份，母鸡的户外活动比例和活动距离都有所增加（p < 0.01）。在阴天和雾天，母鸡在测距范围和测距距离上的百分比分别增加和减少（p <0.01）。此外，应变与年份之间的交互作用以及应变与天气条件之间的交互作用也会影响母鸡的户外活动率（p <0.01）。结论是，母鸡的户外活动率和活动距离可受植物种类和产蛋鸡品系的影响。在进一步的研究中，考虑这两个方面以提高母鸡的散养行为至关重要。
