The possibility was investigated that translocation of juvenile ostriches from concrete-paved to sandfloored pens and mixing of batches of ostriches after such translocation constitute a stress strong enough to evoke changes in the ratio of heterophils to lymphocytes. Blood smears were obtained from 15 ostriches out of a group of 25 birds 4 and 2 days before and then 2 and 4 days after translocation. The heterophil to lymphocyte ratio changed from 0.27 and 0.37 on days 4 and 2, respectively, before mixing and translocation to 0.53 and 0.84 on days 2 and 4, respectively, after translocation. Mixing and translocating juvenile ostriches appears to constitute stress. This information is important for the onfarm management of juvenile ostriches to enhance their welfare and productivity.
研究了将幼年鸵鸟从混凝土铺面围栏转移到沙地围栏以及转移后将不同批次的鸵鸟混合饲养是否会构成足够强烈的应激，从而引起嗜异性粒细胞与淋巴细胞比例的变化。在一组25只鸟中，于转移前4天和2天以及转移后2天和4天从15只鸵鸟身上采集血涂片。嗜异性粒细胞与淋巴细胞的比例在混合和转移前的第4天和第2天分别为0.27和0.37，在转移后的第2天和第4天分别变为0.53和0.84。混合和转移幼年鸵鸟似乎构成应激。该信息对于幼年鸵鸟的农场管理以提高其福利和生产力很重要。
