The challenge
DCAD palatability was limiting the transition program
Dave described large clinical and subclinical milk fever incidents under the previous transition approach. The DCAD ration created a practical problem: cows did not want to eat the full ration.
In his words, the cows were only eating about half the ration, which made the transition program difficult to rely on when the herd needed it most.
The solution
A transition approach that worked in the real ration
X-Zelit replaced the DCAD diet in Dave’s program. The feed cost was described as about the same, but the practical difference was in the problems that disappeared.
Dave reported that X-Zelit worked even when cows were not eating a full ration — solving the palatability issue that had undermined the previous approach.
The result
Zero milk fever, low mastitis and strong herd health
Across 450 cows calved, Dave reported zero clinical milk fever cases. He also reported 9 mastitis cases in the first 21 days, approximately 9 retained afterbirths, and a cell count averaging under 80.
The broader result was a cleaner transition: very good herd health, easier calvings, fewer assists and the potential for better fertility through fewer retained afterbirths.
