摘要
试验旨在研究欧拉型藏羊的生长发育状况,初步探讨欧拉型藏羊的生长发育曲线理论模型并找出欧拉型藏羊养殖的最佳生长点,以期为欧拉型藏羊的选育和饲养管理的改善提供理论依据。选用甘肃省甘南玛曲县欧拉乡牧户的欧拉型藏羊羔羊60只,测定了0（初生）、2、7、14、21、28、42、56、70、84、98、112日龄的体重、体高和体长。采用Logistic、Richards、Exponential Association和Gompertz Relation 4种生长曲线模型对欧拉型藏羊羔羊的生长曲线进行拟合。结果发现：Richards曲线模型最适宜描述欧拉型藏羊体重增长模式,Exponential Association是拟合欧拉型藏羊羔羊体高和体长早期生长过程的最优模型。
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.
