A deterministic simulation was used to compare six breeding schemes based on different levels of performance recording: (1) only body weights, (2) only dairy traits, (3) body weights and reproductive traits, (4) dairy and reproductive traits, (5) body weights and dairy traits and (6) body weights, reproductive and dairy traits. Other factors were also studied, as the level of usage of proven sires, variations in the economic value of slaughter weight and eliminating progeny testing in the beef herd tier […]
