Technical Service Manager Ruminant Delphine Lacombe took part at this year´s ADSA Conference in Itasca, USA. She presented a trial run at “Freie Universität Berlin” on calves with Actifor® Protect in poster format. The focus of the conference was on “natural bioactives in dairy production,” it gathered over 150 industry representatives and research experts.
Young calves are susceptible to diseases in the first stage of life. Improving their resilience as well as their feed intake is crucial for better growth performance, and thus for higher productivity in adulthood. Delacon’s Actifor® Protect was added to a basal calf milk replacer (CMR) in the study, which measured the health status of 40 calves from age 12 to 68 days and lasted 56 days.
By recording performance parameters and health scoring criteria during the trial, it was observed that calves fed with the supplement Actifor® Protect showed higher feed intake and higher body weight gain. Besides better feed efficiency of this group, it was also observed that health criteria were improved in comparison to the negative control group.
When comparing the blood parameters of the two groups, the one fed with Actifor® Protect showed higher antioxidant levels in the blood, meaning that these calves are better armed to resist oxidative stress than the control group. These findings, together with the better growth performances, can be explained by the fact that the animals which did not have to use their energy to fight against inflammation or oxidative stress, which are closely interlinked, could concentrate this energy in growth instead. Actifor® Protect used as a supplement had a positive impact on the animals, during a strategic time in the calves’ lives.
