    Fitting analysis on growth curves of body mass and size of Guinea fowl

    • 摘要:
      目的 

      为系统选育和改良珍珠鸡Guinea fowl生产性能提供基本数据资料。

      方法 

      以1~9周龄珍珠鸡为研究对象,分析其生长发育规律,并采用Logistic、Gompertz、Bertalanffy 3种模型进行拟合分析,探讨其合适的生长模型。

      结果 

      公、母珍珠鸡的体质量、龙骨长、胫长和胫围差异不显著(P>0.05),生长发育规律呈现一致趋势。体尺性状在2周龄生长速率最大,呈直线上升趋势。珍珠鸡体质量与体尺性状间均呈正相关,公珍珠鸡的胫长与体质量的相关系数最大(r=0.752),且达到极显著水平。母珍珠鸡的体质量与龙骨长的相关系数最大(r=0.600),其次为胫长(r=0.509),且胫长与龙骨长之间相关性达到显著水平,相关系数为0.477。3种曲线模型均适合珍珠鸡生长曲线的模拟,其中Gompertz模型是珍珠鸡体质量的最佳拟合模型,龙骨长、胫长和胫围的最佳拟合模型均为Bertalanffy模型。

      结论 

      公、母珍珠鸡体质量和体尺生长发育规律趋势一致,Gompertz、Bertalanffy模型分别是体质量和体尺性状的最佳拟合模型,应加强对胫长指标的选育,有可能间接提高珍珠鸡龙骨长度和胸肌产量,并提高体质量。

      Abstract:
      Objective 

      To provide basic data for selective breeding and improving of reproduction performance of Guinea fowl.

      Method 

      The growth and development patterns of one-to nine-week-old G. fowl were studied. Three different models including Logistic, Gompertz and Bertalanffy models were compared to identify the best model fitting G. fowl growth.

      Result 

      Growth traits including body mass, keel length, shank length and shank girth showed no significant differences between male and female G. fowl (P > 0.05) and exhibited similar trends. The growth rate of body size was the highest with a straight ascending trend at the age of two weeks. The body mass of G. fowl was positively correlated with its body size. For male ones, the correlation coefficent (r=0.752, P < 0.01) between body mass and shank length was the largest. For female ones, the correlation coefficent (r=0.600) between body mass and keel length was the largest, followed by the correlation coefficent (r=0.509) between body mass and shank length. In addition, the correlation (r=0.477) between shank length and keel length was significant (P < 0.01). All three models could be used for fitting G. fowl growth, among which the Gompertz model was the best for body mass and the Bertalanffy model was the best for body size.

      Conclusion 

      There are similar trends in growth and development of body mass and body size between male and female G. fowl. The Gompertz and Bertalanffy models are the best for fitting body mass and body size, respectively. Improving the shank length of G. fowl may help to increase its keel length, pectoral production as well as body mass.
