Hotcross-a decision support aid for crossbreeding of beef cattle in tropical and subtropical environments

Hotcross-a decision support aid for crossbreeding of beef cattle in tropical and subtropical environments

The development of a decision support software (DSS) to aid beef cattle breeders in making decisions about crossbreeding systems for a wide array of environments is described. The DSS, designated Hotcross, can predict differences between genotypes (varying proportions of Bos indicus inheritance) in production and quality traits for the environment in which production occurs. Predicted performance of genotypes is adjusted for 4 environmental stresses: heat, ticks, worms and nutrition.
