Abstract

This study aims to determine the population dynamics, population structure, and increase of Bali cattle population Maiwa Breeding Center partnerships in Barru Regency. This research was conducted from March to April 2020 in Barru Regency, South Sulawesi. The Reproductive Efficiency of Bali cattle was 91%. Population dynamics were only influenced by the calving, mortality, and sale of livestock, with the growth of 27% (2019) and 31% (2020). The population structure was dominated by cows, 31% (2018), 48% (2019), and 54% (2020). Natural Increase (NI) of livestock was 17% (2018), 28% (2019) and 20% (2020). The conclusion of this study is that the growth of the Bali cattle population of MBC partnerships was still low when according to calving and income because it does not reach 80% of cows based on population even shows a tendency to decrease calving.

Abstract

Livestock is one of the agricultural sectors that plays an important role in providing animal products. Cows are one of the largest meat and dairy producers. The low reproductive efficiency of cattle is the biggest problem in terms of its development. Increasing reproductive efficiency through artificial insemination programs is one way to enhance livestock populations. Reproductive efficiency parameters can be measured through values of Service per Conception (S/C) and Conception Rate (CR). Service per conception and conception rate are related to cows parity. Parity is the number of calf that have been born to a cow. This study aimed to provide information on reproductive efficiency as seen from the value of S/C and CR of cows in different parieties and the factors that influence them. High rates of parity followed by high S/C score and low CR. Each animal has various values of S/C and CR. The normal range for S/C is 1.6-2.0 and 60% in CR. Several factors that affect reproductive efficiency are environment, nutrition, Body Condition Score (BCS), knowledge of farmers, inseminator skills and quality of semen used. The highest service per conception (S/C) value was at parity 5 with aged ± 7 years and the conception rate (CR) was at parity 3 aged ± 5 years.Keywords: should be written in no more than 5 (five) words or phrases.
