The composition and benefits of transition milk

Transition milk, produced by cows during the first few days after calving, represents a critical nutritional resource for neo­natal calves. Research has demonstrated that transition milk plays a significant role in calf health and development due to its unique composition. This paper explores the composition and benefits of transition milk, with a focus on its role in support­ing calf immunity, growth and overall well-being. The initial postpartum period in dairy cows is marked by the secretion of transition milk, which is produced after colostrum and before mature milk. Transition milk plays a vital role in bridging the gap between the highly concentrated nutrients of colostrum and the more stable composition of mature milk. Recent research has provided deeper insights into the composi­tion and health benefits of transition milk, highlighting its im­portance in early calf nutrition.
