The low performance of Saburai goats was due to the limited number of females so almost all Saburai goats were selected as potential stock in the area. This results in a low intensity of selection and a lower increase in the growth of the next generation. This research was conducted in Gisting and Sumberejo Subdistricts, Tanggamus District and we aimed to determine the body weight and body sizes of Saburai goats doe who have single and twin birth types. Data collection was carried out on 62 Saburai goats doe in the study area. Data were analyzed by t-test. The results showed that the average body weight, body length, shoulder height, chest circumference, chest width, chest depth, hip width, and hip height were 43.62±1.08 kg, 62.79±2.76 cm, 62.31±1.57 cm, 75 .74±2.56 cm, 20.39±2.41 cm, 30.54±1.89 cm, 15.93±0.86 cm, 68.35±0.73 cm in single births does and 44.25±1.34 cm, 64.05±2.62 cm, 66.48±1.86 cm, 81.55±1.24 cm, 22.95±1.03 cm, 32.51±0.71 cm, 17.31±0.69 cm, and 69.91±0.81 cm in twin births does respectively. The results of the t-test showed that the average body size of the single-birth-type was significantly (P<0.05) different from twin-breed Saburai goats. The quantitative performance of the Saburai goat doe with twin birth types was higher than that of the single birth type.
