During the first 4 weeks the feed intake were +0.5 kg DM higher for the X-Zelit group. This ensures a higher energy intake in the animals, which probably explains some of the positive effects found on other production traits.” X-ZELIT AND COLOSTRUM QUALITY High quality colostrum is of crucial importance for the health and wellbeing of the newborn calf.
