产卵在一个适当的巢是一个行为的优先级在蛋鸡，和层菌株是已知的不同模式的巢使用。然而，除了产卵，产蛋鸡往往表现出不受欢迎的行为，如侵略或群居筑巢在群体巢箱。本研究的目的是通过将两用母鸡（Lohmann Dual，LB+）与传统产蛋母鸡品系（Lohmann Brown plus，LB+）进行比较，获得有关两用母鸡（Lohmann Dual，LB+）的巢使用模式和巢内行为的基本信息。）。此外，巢的位置的影响进行了测试，为每个混合。每个遗传品系约1850只未修剪的母鸡被圈养在禽舍系统的四个隔间中，顶层是菌落巢箱。在产蛋期间，在每个隔室的一排巢箱中的第一个（N1）和第六个巢（N2）中记录三次基于视频的数据，以评估每个巢的母鸡数量、焦点动物的巢访视持续时间以及巢中母鸡的行为。一般而言，每个巢箱观察到LD（0.87 +/- 0.09-10.63 +/- 0.30）的数量大于LB +母鸡（0.21 +/- 0.04-4.90 +/- 0.24）。在两个杂交组合中，N1组的产蛋率显著高于N2组（P < 0.05）。除第43 - 48周龄外，LB+（09：51 +/- 00：41-18：25 +/-00：48 mm：ss）和LD母鸡（07：14 +/- 00：32-17：14 +/-00：32 mm：ss）之间的访巢持续时间没有差异。但两种杂种在N2中的停留时间均显著高于N1（P < 0.05）。几乎所有观察到的行为都存在混合效应（P < 0.05）。特别是，LB+母鸡进行更多的总啄食行为，而LD母鸡在巢中表现出更多的堆积。在LB+母鸡，巢的位置只影响少数的行为。与此相反，巢的位置效应被发现的LD母鸡中观察到的大多数行为。特别是N1发生的打桩事件较多。目前的研究结果表明，模式的巢使用和行为在巢中不同的常规层和两用鸡。在遗传应变，两用母鸡似乎更受巢的位置比传统的蛋鸡。
Oviposition in an appropriate nest is a behavioural priority in laying hens, and layer strains are known to differ in their patterns of nest use. However, besides oviposition, laying hens often show undesired behaviours such as aggression or gregarious nesting in colony nest boxes. The aim of the present study was to obtain basic information on the patterns of nest use and the behaviour in the nest of dual-purpose hens (Lohmann Dual, LB+) by comparing them to a conventional layer strain (Lohmann Brown plus, LB+). In addition, the effect of nest location was tested for each hybrid. About 1850 untrimmed hens per genetic strain were housed in four compartments of an aviary system with colony nest boxes on the top tier. Video-based data were recorded in the first (N1) and the sixth nest (N2) in a row of nest boxes in each compartment at three times during the laying period to assess the number of hens per nest, the duration of nest visits of focal animals, and the behaviour of the hens in the nest. In general, a larger number of LD (0.87 +/- 0.09-10.63 +/- 0.30) than LB + hens (0.21 +/- 0.04-4.90 +/- 0.24) was observed per nest box. In both hybrids, more hens were found in N1 compared to N2 (P < 0.05). Except for 43rd -48th weeks of life, the durations of nest visits did not differ between LB+ (09:51 +/- 00:41-18:25 +/- 00:48 mm:ss) and LD hens (07:14 +/- 00:32-17:14 +/- 00:32 mm:ss). However, both hybrids spent more time in N2 compared to N1 (P < 0.05). Hybrid effects (P < 0.05) were found for nearly all of the observed behaviours. In particular, LB+ hens performed more total pecking behaviour, whereas LD hens showed more piling in the nest. In the LB+ hens, nest location affected only few of the behaviours. In contrast, nest location effects were found for most of the behaviours observed in the LD hens. Particularly piling occurred to a larger extent in N1. The present results indicate that the patterns of nest use and the behaviour in the nest differed between conventional layers and dual-purpose hens. Within genetic strain, dual-purpose hens seemed to be more affected by nest location than conventional layers.
