Which is better, using Burker chamber regularly or a colorimeter?
Burker chamber is an extremely precise instrument to estimate ejaculate concentrations, but the necessity to work with much reduced volumes and the time required make this technique considerably slower than the colorimeter. The main advantages of using a colorimeter are speed and repeatability. Variability among various estimates of a colorimeter is about 3%, whereas this may be up to 13% for Burker chamber counting. One of the main disadvantages of using a colorimeter, apart from its cost, is that, occasionally and due to the characteristics of the seminal plasma of their ejaculate, some boars tend to distort upwards the results of the colorimeter, which is not significant when these boars are identified. On the other hand, even insemination centres that regularly work with colorimeter should always have at least a Burker chamber to calibrate the colorimeter and check its correct functioning. The use of a system of colorimeters is advisable in large and medium insemination centres. In
