摘要：
First lactation records of 507 Surti buffaloes, sired by 41 bulls, maintained at Buffalo Project, Livestock Research Station, Vallabhnagar (Rajasthan) were utilized to develop multi-trait selection indices. Ten complete restricted selection indices (RI1 to RI10) were developed by imposing single or 2 trait restrictions on AFC, FSP, FLL and FCI. The index coefficients (b(i)), expected genetic gain in each trait (G(i)), correlation between index and breeding value (R-1H) acid aggregate genetic gain (Delta H) were compared and it was observed that the complete restriction on FCI would be the most appropriate for genetic improvement. This would produce a desirable genetic change in FLMY (5.5686 kg), AFC (-31.0264 days), FDP (-0.0651 days), FPY (0.0325 kg) and FSP (-0.2024 days).
