تقدير معالم دالة تنبؤ منحنى النمو لأوزان الإبل الشامية قبل النضج في سورية

Abstract EN

The aim of this study was to estimate the growth curve prediction equation for weights from birth to four years old of Shami camel.

This study was carried out on 358 records of Shami camel, during the period from 1996 to 2012 at Dier Alhajr station for camel research, animal wealth research administration, General Commission Scientific Agriculture Research, rural Damascus (Syria).

The results showed high values of coefficient determinates (0.97-0.98), while standard errors values ranged between (27.26-34.13), and residual values ranged between (0.32-107.72), for each linear, quadratic and cubic equations.

The values were fittest at linear regression equation for males, females and each (male and females).

The parameters values of linear equation were goodness for prediction, where the intercept value was (A=37.80±17.76), while the increase in weight values of camel growth curve from birth till four years of age was (B=8.06±0.65).

The study concluded that, might be described growth curve at Shami camel by simple linear equation from birth to four years of age, and the linear equation was fitted for Shami camel weights prediction from birth to four years of age, under rearing partially concentration of Shami camel in Syria.
