Reproductive performance not black and white

It is not possible to have a good herd reproductive performance without good heat detection — and good heat detection is not possible without aids.

The most common and effective aid is tail painting. Stick-on devices are also effective. Like tail paint, they must be properly applied throughout the AI season.

Large-scale farmers usually prefer to use vasectomised bulls with chin balls; these are also very effective. Make sure these bulls are free of transmittable diseases.
