| 【目的】麒麟鸡与怀乡鸡是产于粤西一带的优良地方品种，探 索两个地方品种鸡早期的生长发育
规律，为其资源保护和开发利用提供理论依据。【方法】通过测定麒麟鸡和怀乡鸡 0~16 周龄的体质量，采用
Logistic、Gompertz 和 Bertalanffy 3 种模型分别对其生长情况进行拟合分析。【结果】3 种模型的拟合曲线拟合度
均在 0.979 以上，其中对怀乡鸡的拟合度普遍优于麒麟鸡，Logistic 模型的拟合度较差，而 Bertalanffy 模型对麒
麟鸡和怀乡鸡的拟合度最高，且能更好地描述怀乡鸡的实际生长情况。Bertalanffy 模型拟合的麒麟鸡和怀乡鸡拐
点周龄分别为 11.4 周龄和 5.8 周龄，拐点体质量分别为 894.1 g 和 498.7 g，所得到的麒麟鸡生长曲线方程为：
Y=3017.521×〔1-0.726exp（-0.068t）〕3
，怀乡鸡生长曲线方程为：Y=1683.001×〔1-0.787exp（-0.147t）〕3。
【结论】Bertalanffy 模型对麒麟鸡和怀乡鸡的生长曲线拟合较合适，通过生长发育规律的分析，获取了相应的生
长曲线和关键参数，为两个地方品种鸡的资源保护、品种选育与产业化发展提供一定的科学依据。 |

| 【Objective】Frizzle chicken and Huaixiang chicken are excellent local breeds produced in the west
of Guangdong. The early growth and development rules of the two local breeds of chickens are explored so as to provide
a theoretical basis for the protection, development and utilization of their resources.【Method】By measuring the body
weights of Frizzle chickens and Huaixiang chickens aged 0-16 weeks, Logistic, Gompertz and Bertalanffy models were
used for fitting analysis of their growth.【Result】The fitting degree of the fitting curve of three models was above 0.979,
and the fitting degree of Huaixiang chicken was generally better than that of Frizzle chicken; the fitting degree of Logistic
model was poor, while the fitting degree of Bertalanffy model was the highest for Frizzle chicken and Huaixiang chicken,
and it could better describe the actual growth situation of Huaixiang chicken. The ages of growth inflection point of Frizzle
chicken and Huaixiang chicken fitted by Bertalanffy model were 11.4 weeks and 5.8 weeks respectively, and the weights of
growth inflection point were 894.1 g and 498.7 g respectively. The growth curve equation of Frizzle chickens was as follows:
Y=3017.521×〔1-0.726exp（-0.068t）〕3
, and the growth curve equation of Huaixiang chickens was: Y=1683.001× 〔1-0.787exp（-0.147t）〕3
.【Conclusion】Bertalanffy model is suitable for the growth curve fitting of Frizzle chickens and
Huaixiang chickens, and the corresponding growth curve and key parameters are obtained through the analysis of the growth
and development rules, which provides a certain scientific basis for the resource protection, breed selection and industrial
development of the two local chicken breeds . |
