Abstract: On the basis of the current two-tire nucleus breeding scheme and young bull system for beef line of Luxi cattle, the backfat thickness and eye muscle area of rib scanned in yearling live cattle and mean concentration of IGF-Ⅰin plasma at 28th,42nd and 56th day of post-weaning period in calf were used as early records of carcass traits in this study. Four selection schemes which differed in the records available for use as selection criteria were defined, and deterministic simulation was used to evaluate 4 selection schemes for breeding efficiency. The results showed that taking if the scheme 1 (current scheme) contrast with other schemes, then index accuracy, genetic gains per year and profitability were improved 0.19, 39.05％ and 63.60％ for scheme 2; 0.01, 25.55％ and 14.90％ for scheme 3; 0.21, 40.68％ and 64.08％ for scheme 4. According to the results, the schemes taking the ultrasound scanning and IGF-Ⅰas selection criteria would get more ideal breeding efficiency in the breeding schemes.
