ISSUE FOCUS 32 FEED & ADDITIVE MAGAZINE January 2024 The effect of MCFA was most pronounced during summer season (Figure 3). IgG and BRIX were significantly higher during the more challenging summer period for the ABC treated cows compared to the control. Indeed, during summer time, colostrum fat and protein content tend to be lower when compared to other seasons. Differences between control and ABC were smaller in winter, but showed similar trends. Altogether, results indicated ABC had a positive effect on colostrum quality, especially when circumstances were more challenging. IMPACTING CALF IMMUNITY BY MCFA IN THE MOTHER’S DIET At Agrimprove, we work every day to develop solutions helping farmers to improve the profitability of their farm. Fast and healthy rearing of calves is an essential element for the farmer to obtain commercial success. This study demonstrated the potential of Aromabiotic® Cattle as part of the dry cow diet to improve colostrum quality. Therefore, MCFA in mother’s diet supports calf rearing success.
