PENDUGAAN BOBOT HIDUP SAPI PERANAKAN ONGOLE (PO) DAN SAPI PESISIR MENGGUNAKAN PENCITRAAN DIGITAL
Abstract: This research aimed
to estimate cattlelive weight by digital imageanalysis using two variables,
namely side body surface area (LPTS) and back body surface area (LPTB).
Thestudyused 40 heads of PO cattle and 45 heads Pesisir cattle. The body
surface of cattle was visualized by digital camera and the image was analyse by
autocad software. The combination of LPTS and LPTB was correlated to live
weight of cattle with coefficient determinatoin (R2) of 70.57 % and 40.96 % for
PO and Pesisir cattle respectively. The established regretion equation gave
standard error of 51.63 kg for PO cattle and 25.54 kg for Pesisir cattle.
Therefore, the estimation of cattle live weight based on LPTS and LPTB was not
suggested as their hight prediction error.
