The purpose of this study was to compare the productivity of Fat-Tailed Sheep in single and twin lambing. The research method was a field study based on data recording of ewes that gave lambing three times or more. The variables observed were livestock productivity seen from the interval between giving birth and the reproduction rate of livestock. Data analysis used unpaired t-test with excel program. The results showed that twins had a very significantly higher reproductive rate (P < 0.01) and no significant difference between lambing intervals (P > 0.05) compared to single lambing ewes. This study concluded that the productivity of Fat-Tailed sheep was 88.19 % higher ewes of twin lambing than that of single lambing ewes. One of the criteria for choosing a ewe is the potential for twin lambing.
