Male and female Saburai goat were used as breeding stock for 4.44 ± 0.20 years and for 5.03 ± 0.21 years, respectively. Replacement stock needed in 2018 were highest (25.39 % for male and 27.91 % for female). Percentage of Saburai goat birth were 9.72 ± 6.57 % for male goat and 19.72 ± 5.18 % for female. Value of NI for male and female goat were 9.25 % and 19.13 %, respectively. Value of NRR in 2018 were highest (male 114.69 % and female 458.94 %).
