Studied were histopathologically 7421 chick embryos of eggs at the end of the incubation period, originating from flocks raised under industrial technology. Established were a total of 39 deformities that involved all body parts in 6.28% of the studied embryos. First in number ranked the malformations of the legs and feet (curved legs and feet micromelia, achondroplasia), followed by head deformities (acrania), etc. Most of the affected embryos were single (simple), however, double ones (connected) were also encountered; 64.6% of them had one defect only, 29.9% had two defects, and the remaining 5.2% had three defects and more. Age-associated limits of the affected embryos ranked within the 15-21-day range.
对7421只孵化期末的鸡胚进行了组织病理学研究，这些鸡胚来自采用工业技术饲养的鸡群。共发现39例畸形，占研究胚胎的6.28%，涉及身体所有部位。腿部和足部畸形（弯曲的腿和足短小畸形、软骨发育不全）数量最多，其次是头部畸形（无颅畸形）等。大多数受影响的胚胎为单发（单纯型），但也发现了双发（联体）的情况；其中64.6%仅有一处缺陷，29.9%有两处缺陷，其余5.2%有三处及更多缺陷。受影响胚胎的年龄相关范围在15至21天之间。
