Factors Influencing Ranging Behavior of Different Strains of Hens
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.
