Abstract :
This study compares four sigmoidal models
using 770 weekly body weights data of Cihateup duck
male n=14 and Cihateup Female n=21 collected over 22
weeks. Four sigmoidal models, Richards, Gompetz,
Logistic and Morgan-Mercer-Flodin (MMF) were fitted
to determine the best model curve. R
2 and SE values
were used for model determination. The R
2
values for
these models were; 0.9956, 0.9956, 0.9955 and 0.9928
respectively in males, and 0.9982, 0.9964, 0.9979 and
0.9970 for females respectively. The SE values for the
respective models were 41.0852, 41.0852, 40.3999 and
52.4300 in males while 23.0558, 31.7047, 24.3066 and
29.9865 in females. Richards function was suitable for
the Cihateup breed better than the other three models
based on higest R
2 and lowest SEvalues
