Evaluation of Colostrum Quality - A Narrative Brief Overview

The objective of this narrative review is to synthesize studies relating to the estimation of colostrum quality on farms before feeding neonates. This is one of the best ways to ensure that the colostrum management program succeeds in transferring passive immunity to provide sufficient protection from pathogens and improve their health. It should be rapid, inexpensive, and easy to use. Colostrum is the first milk secreted by female mammals immediately after birth during the first few days, and its composition differs from that of the mature milk. It contains unique components rich in nutritional micro and macronutrients, and many bioactive substances like antimicrobial factors, growth factors, which all newborn mammals need to develop the digestive system, resist microbial infections, and boost immune systems to promote lifelong health and immunity, it is a divine immune gift from the Creator. Consequently, newborns should receive sufficient high-quality colostrum containing optimal immunoglobulins (Igs) level within the first few hours after birth to protect them from pathogens until the immune system develops. Therefore, the estimation of colostrum quality should be routinely checked on farms prior to feeding neonates. Colostrum quality assessment is based on the Igs level, where high-quality colostrum is defined as having an IgG value ≥ 50 mg/mL, and it can be evaluated using direct or indirect methods. It can also be improved when factors affecting the nutritional and immunological composition are considered.
