Milk density determination А/ With pycnometer and Mor-Vestval scales This is the most exact method for determination of milk and its derivatives’ density.
B/ With aerometer (lacto-density-meter) Compared with the above method this is quick and easy readable with satisfactory accuracy. For more detailed description see Appendix Methods. During the lactation period and under the influence of different zoo engineering factors the density of the different milk kinds varies in the following bounds:
