Abstract

The purpose of this research was to know the growth model of Mojosari duck’s thymus organs. The total sample used in this study was 30 Mojosari ducksfrom DOD untill 28 weeks age. The variables observed were weight of thymus, wide cortex and medulla of thymus, as well as cell density of Mojosari duck’s thymus. All data were processed usingsoftware Image-J and analyzed using quadratic non-linear regression analysis to find growth model of Mojasari duck’s thymus and statistical analysis using ANOVA. The results of this research showed that weight of the thymus organs are increase from DOD and reach the highest weight at the age of 10 weeks, then decrease at the next age untill 28 weeks, and formed a quadratic regression nonlinear growth model. Cortex and Medulla of the thymus increase from DOD age and reach the maximum area at age 12 weeks than the area is decrease in later age and formed a growth model quadratic regression nonlinear. The density of Mojosari duck thymus showed that the maximum cell density occured at DOD age and then continuously decrease and shows a growth model quadratic regression nonlinear. This research showed that thymus weight, cortex and medulla area, as well as thymus cell density can be used to see the growth model of the organs of the Mojosari duck thymus using Image-J software.
