欧拉型藏羊生长发育曲线模型预测及趋势分析
Growth Curve Model Prediction and Trend Analysis of Oula Tibetan Sheep
摘要
Abstract
This paper aimed to study the growth and development of Oula Tibetan sheep,and make a preliminary discussion on growth curve model and a trend analysis for improving the Oula Tibetan sheep breeding and the feeding management. 60 grazing Oula Tibetan sheep were chosen and the weight,height and body length of newborn,2-day-old,7-day-old,14-day-old,21-day-old,28-day-old,42-day-old,56-day-old,70-day-old,84-day-old,98-day-old,112-day-old were measured. The growth curves of Oula Tibetan sheep were analyzed with four kinds of nonlinear models(Logistics,Richards,Exponential Association and Gompertz Relation). The results showed that the growth curves were appropriately fitted with Richards and Exponential Association.关键词
