Developing a criteria to select colostrum samples of poor quality

Dr. Sarah Hazelton | 2018

Good colostrum management is essential to the health of newborn replacements and lifelong profit as it directly links to an adequate transfer of immunity to the calf.

While the farmer found it was not possible to develop a set criteria to select animals that would produce low-quality colostrum, the project showed that that testing colostrum was important ahead of making assumptions like age of animal, which has been a standard criteria for years.  It also showed that testing could confirm the energy status of the animals.
