      Abstract
      Estimasi bobot hidup pada seekor sapi dapat memudahkan dalam mengetahui bobot aktualnya. Salah satu cara mengestimasinya dengan menggunakan ukuran linier tubuh sapi. Penelitian ini bertujuan menduga bobot hidup berdasarkan ukuran linier tubuh pedet lepas sapih Simmental dan Limousine. Penelitian menggunakan data sekunder yang diperoleh dari Balai Pembibitan Ternak Unggul dan Hijauan Pakan Ternak Padang Mengatas. Total sebanyak 128 ekor Sapi Simmental dan Limousine dengan kisaran umur 6-18 bulan, dengan perbandingan 26 ekor jantan Simmental, 50 ekor betina Simmental, 19 ekor jantan Limousine, dan 33 ekor betina Limousine digunakan pada penelitian ini. Metode analisis data dengan regresi linier berganda. Penelitian ini menunjukkan bahwa pendugaan bobot hidup dengan menggunakan ukuran linier tubuh pada sapi Simmental dan Limousine pada fase pedet lepas sapih menghasilkan persamaan Y = -401,98 + 0,96(PB) + 2,71(LD) + 1,15(TP) dengan nilai koefisien determinasi (R2) sebesar 90,91% dan nilai standar error 13,07kg. Secara keseluruhan hasil pendugaan tidak berbeda nyata dengan bobot aktualnya.
       
      Live weight estimation in a cow can make it easier to know the actual weight. One way of estimating it is by using the linear size of the cow's body. The aim of this study was to estimate live weight based on body linear measurements of Simmental and Limousine weaning calves. The study used secondary data obtained from the Center for Superior Cattle Breeding and Forage Animal Feed Padang Atas. A total of 128 Simmental and Limousine cattle with an age range of 6-18 months, with a comparison of 26 Simmental males, 50 Simmental females, 19 Limousine males, and 33 Limousine females were used in this study. Method of data analysis with multiple linear regression. This study showed that the estimation of live weight using linear body measurements in Simmental and Limousine cattle in the weaning calf phase resulted in the equation Y = -401.98 + 0.96(PB) + 2.71(LD) + 1.15(TP). Result equation with a coefficient of determination (R2) of 90.91% and a standard error of 13.07kg. Overall, the estimation results are not significantly different from the actual weights.
