Description of Optical Refractometer
With this optical refractometer, you will be able to estimate the quality of the colostrum on-farm.
The newborn calf doesn’t have any immunity. The only protection it has is colostrum.
From the 6th day after the birth, it begins to synthesize antibodies and acquired immunity appears 3 to 5 weeks after birth. Necessary additional protection is brought by the mother through colostrum to make the transition. The calf is completely dependent on antibodies brought by the colostrum. Colostrum, naturally rich in antibodies and in antibacterial proteins, participates actively in the digestion of the young calf.
