Best Linear Unbiased Prediction. This is the only scientific breeding tool that we have available today. Genomics will be a great tool in the futue, but at the moment Blup does a fine job in predicting a breeding outcome if the accuracy of the data is above 66%. It is only a prediction tool, visual selection and weighing remains important and will never be replaced. We can however not risk using animals without accurate blup values. The only way to measure Feed Convertion is in a Face C test. The only accurate way to measure scrotal circumferance, ribeye area and marbling is by scanning all the animals at the same age, at the end of a test. They all then had the same diet for a 100 days, the effect of enviroment thus eliminated.
