| 摘 要： | 文章旨在研究体外鸡胚注射肉碱对肉鸡孵化率及出壳后49 d肉鸡生长性能和屠宰性能的影响。鸡胚在孵化第18天通过羊膜注射0.6、2.4和9.6 mg左旋肉碱/100μL稀释液,此外还有3个对照组(非注射组、穿孔组和注射稀释液组),评估肉鸡孵化率、生长期肉鸡死亡率、增重、采食量和料比以及屠宰性能指标(屠宰率、腹脂、小腿肌、大腿肌、鸡翅和胸肌占比)。结果发现:鸡胚注射左旋肉碱对受精蛋孵化率无显著影响(P>0.05),但随左旋肉碱注射量的增加,受精蛋孵化率和仔鸡出壳时间有升高趋势(P=0.08)。鸡胚注射左旋肉碱对出壳后49 d肉鸡生长性能、死亡率及屠宰性能指标均无显著影响(P>0.05)。结论:鸡胚注射0.6、2.4和9.6 mg左旋肉碱/100μL稀释液对出壳后肉鸡生长性能和屠宰性能无显著影响,但可以改善肉鸡出壳时间和受精蛋孵化率。
