, : Results of performance tests of poultry in 1976. Nas Chov 37(4): 164-167

Data are tabulated on the performance over 500 days of 19 egg-producing types of domestic fowl (2 from Bulgaria, 3 from Hungary, 4 from the German Democratic Republic, 1 from Poland, 5 from the USSR, and 4 from Czechoslovakia). The Tetra SL hens from Czechoslovakia rated the best in egg production for 360 days (257.6), production of egg mass/hen (15.69 kg), and mortality from 140 to 500 days of age (3.3%).
