洗浴池水体污染对马岗鹅雏鹅胫骨发育的影响

洗浴池水体是水禽饲养环境中重要的组成部分.目前关于洗浴池水体污染对于水禽生长发育的具体影响仍知之甚少. 由于骨骼发育是影响鹅生长性能的重要指标，本试验以20日龄马岗鹅为试验对象，以不同的洗浴池换水频率构建不同的洗浴池污染程度，来检测洗浴池水体污染对雏鹅胫骨生长发育的影响. 结果发现不同的换水频率显著影响了水体总菌落数.通过胫骨测量、HE染色等方法发现，洗浴池水体污染在雏鹅27日龄时显著降低了胫骨直径和髓质厚度，而在34日龄时则显著降低了胫骨的骨质厚度.本研究为今后通过改善鹅养殖环境，提高鹅生长效率提供了有益借鉴.

Effect of bathing pool water pollution on tibia development of Magang goslings

Bathing pool water is an important part of waterfowl breeding environment. At present, little is known about the specific impact of bathing pool water pollution on the growth and development of waterfowl. As bone development is an important factor affecting the growth performance of geese, 20-day-old Magang geese were used as the experimental objects, and different water-changing frequencies were set to investigate bathing pool water pollution on tibia development. The results showed that different water-changing frequency significantly affected the total number of bacterial colonies in the water. Water pollution of bathing pool also significantly reduced the tibia diameter and medulla thickness of goslings at 27 days of age, and the bone thickness of tibia at 34 days of age. This study provides a useful reference for increasing geese growth performance by improving breeding environment.
