Aplikasi Ukuran Linier Tubuh sebagai Penduga Bobot Badan pada Kerbau Rawa
ABSTRACT: The objective of
this research was to predict swamp buffalo weight using simple linier body
measurement. The height of wither (TB), height of hip (TP), heart girth (LiD),
width of chest (LD), dept of chest (DD), width of hip (LP), thurl length (PK),
width of rump (LK), body length (PB) were measured in centimeters using
measuring rib, one meter ruler, and measuring stick, whereas body weight was
determined in kilograms using two tons weighing scale. Linier body measurement
ratio between male and female swamp buffaloes was analyzed using t-test
analysis. The relationship between linier measurement variables were analyzed
using correlation analyisis. Body weight estimator was estimated using best
subset regression, linier regression and multiple linier regression analysis.
Result of T-test analysis showed that linier body measurement between male and
female buffaloes have signifcant difference in hearth girth, height ofhip and
body length. Result of coeffcient analysis showed that heart girth and height
of hip have ahighly correlation with body weight of male and female swamp
buffalo. Estimation of swamp buffalobody weight could be estimated through
multiple regression with heart girth and height of hip variables. It could be
concluded that weight of swamp buffalo can be estimated using multiple linier
regression formula, BB = 3.6435LiD + 0.1208TP - 265.43 for male swamp buffalo
and BB = 4.1783LiD – 0.3086TP - 305,19 for female swamp buffalo.
Key words: body measurement,
body weight, linear regression, swamp buffalo
