Abstract

This study examined whether a free range with roofed boxes with sand to structure the hen run had an effect on the numbers of hens going outside and on the distribution of the hens in the hen run. 2. On a poultry farm with 8 flocks of laying hens of roughly 500 birds per flock, each flock was observed with and without roofed boxes with sand. 3. There was no difference in the number of hens on free range with and without roofed boxes but there was an influence on the distribution. 4. In free range with structures there was a higher percentage of the hens outside in the furthest quarter where the structures were located. 5. We conclude that structures in the free range have an effect on the distribution of laying hens.

摘要

本研究考察了带有带顶棚沙箱的自由放养区域对母鸡外出数量以及母鸡在放养区域内分布的影响。2. 在一个家禽养殖场，有8群产蛋母鸡，每群约500只，对每群母鸡分别在有和没有带顶棚沙箱的情况下进行观察。3. 有无带顶棚沙箱的自由放养区域内母鸡数量没有差异，但对分布有影响。4. 在有建筑结构的自由放养区域，位于建筑结构所在最远处区域的母鸡外出比例更高。5. 我们得出结论，自由放养区域内的建筑结构对产蛋母鸡的分布有影响。
