Aplikasi Linier Ukuran Tubuh untuk Seleksi Fenotipik Bibit Induk Sapi PO di Kabupaten Bojonegoro
Abstract: The objective of
this research was to predict body weight of Peranakan Ongole (PO) cattle using
simple linear body measurement. The height wither (HW), body length (BL), heart
girth (HG) and chest widht (CW) were measured in centimeters, using caliper, whereas
weaning (WW) and yearling weight (YW) was determined in kilograms using a
weighing scale. Results of the correlation coefficient showed that hearth girth
(HG) highly correlated with body weight was 0.99. In all, the body lenght (HW)
had the least correlation coefficient was 0.30 on body weight. Results of the
stepwise regression showed that HG was a good estimator of body weight PO
cattle. The comparison of residuals indicated that only two equations accurately predicted body weight. From these
results, it was concluded that body weight of Female PO cattle can be estimated
using simple linear body measurement of heart girth especially in most remote
areas where farmers are challenged with the unavailability of weighing scale
