摘  要：
为了掌握不同年龄、季节的獭兔体重分布规律,了解季节对獭兔生长发育的影响,以四川省獭兔原种场獭兔生长发育数据为分析对象,根据分析需要,将全年数据分配进12×8阶矩阵(季节×年龄),采用matlab2010a软件中的曲面拟合功能分析,并进行不同年龄獭兔的季节间体重多重比较。结果表明,体重分布曲面显示,91~180日龄与7~10月份体重分布明显凹陷,极大值与极小值差异显著(P<0.05),差异达500 g左右,而极大体重分布区位于2~4月份的200日龄左右,56日龄前为双峰,后为单峰;不同季节出生獭兔体重分布显示,91~210日龄,夏季出生的体重最大,春季出生的体重最小;增重曲面分布显示,有2次生长峰,包括第1次内源生长与第2次补偿生长,峰均呈马鞍形,鞍底位于夏季,第1次在8月份左右,第2次在6月份左右。结果说明,夏季是影响獭兔生长的主要季节,对几乎各年龄段獭兔均表现为抑制生长,冬季主要抑制56日龄前的仔幼兔生长;獭兔生长存在比较明显的补偿生长现象,而且季节因素对第1次生长峰影响越大,补偿生长就越强;二元5次多项式用于生长曲面拟合,获得了很好的拟合效果,可用于生长预测和生长发育规律探索。

摘  要：
To master the distribution regularity of Rex rabbit's weight in different ages and seasons,and understand season's impact on growth of Rex rabbits at different ages,growth data of Rex rabbits was allotted into 12×8 order matrix(season×age),curve surface fitting tool of matlab2010a was adopted,multiple comparison between weights in different seasons was carried out.The results showed as follows:the obvious pit of weight distribution located between July to October and 91- to 180-day-old,difference between extreme weights at this stage achieved significant level(P<0.05),and the difference of weight was up to 500 g approximately.And then,ridgy area of distribution was located in February to April and approximate 200-day-old,weight distribution present twin-peaks prior to approximate 56-day-old,and then single peak;weight distribution of Rex rabbit born in different seasons demonstrated that rabbits born in summer gained maximal weight during 91 to 210 days,minimum weight was gained by rabbits born in the spring;daily gain surface distribution showed twin-peaks,which included endogenous growth and the compensation growth,peaks presented saddle-shape,the bottom of saddle was located in the summer.The first peak was presented in August,and the second peak was presented in June.The results indicate that the summer is the main season affecting the growth of Rex rabbits,and the suppression role almost involve in the whole age stages,winter mainly inhibit growth of rabbits before 56-dayold;rabbits own classical compensation growth ability,and the more serious impact of season on the first growth peak,the stronger compensation growth;Bivariate polynomial five times,which display better fitting effect,is suitable for growth prediction and exploration of the growth rule.
