Breeding program evaluation for dual purpose zebu cattle
[摘要] - A deterministic approach was used to predict genetic gain and net present value for a breeding program in a dual-purpose zebu cattle population. The considered criterias were body weights, dairy and reproductive traits. High genetic gains and profit were obtained. More than 70% of genetic profit was net present value, justifying selection costs. The small proportion of recorded animals in relationship to the beneficial population of the improvement and the high economic values of traits could explain this profit.
