Abstract

ABSTRACT Native Indonesian beef cattle have existed in Indonesia for a long time. Local beef cattle originate from outside Indonesia but have been bred and cultivated for a long time in Indonesia, so they have specific characteristics. Balinese cattle (Bos sondaicus) are beef cattle native to Indonesia, while local cattle are Madurese cattle and Sumba Ongole (PO) cattle. This study aimed to determine the population structure of beef cattle and the population dynamics of beef cattle based on the percentage of births, deaths, and the slaughter of productive females.

The population structure based on age is adult 60.47% (male 21.34% and female 39.13%, heifer 28.26% (male 15.47% and female 12.79%), and calf 11.27% (male 5.72% and 5.55% for females. Population dynamics based on the birth rate for the past year is 11.27%, the mortality rate is 3.62% (2.41% for males and 1.21% for females), while the slaughter rate productive females as many as 11 heads with a percentage of 1.65%.
