The objective was to determine beef yield in the progeny after selected breeding bulls of simmentalized breeds of domestic and foreign provenance. Average daily live weight gains ranged from 1,172 g and 1,193 g in groups D and E to 1,342 g and 1,363 g in groups C and F by about 480 days of age, and from 1,310 g and 1,325 g to 1,458 and 1,454 g in the same groups by one year of age. Average growth rate in groups A and B was at the middle level between the above pairs of groups. (Groups A to E include progenies after different sires. Similar results of the group position were determined for net weight gains. There were no large differences in nutrient consumption per feeding day between the groups, and nutrient consumption per unit of production was determined by the growth rate. The weight of dressed carcass was influenced by pre-slaughter weight, and the differences in dressing percentage were insignificant.
