Riku Tella has a mixed herd consisting of approximately equal numbers of RDC and Holstein cows. The herd is milked by one robot, with an average milk yield of 12,100 kg ECM (11,000 kg milk, 4.4% fat and 3.7% protein).
The herd’s breeding strategy is to use sexed semen on the top females and beef semen on the rest, maximising both genetic progress and the overall profitability of the herd.
Milk yield must be maintained at a sufficient level in breeding decisions to ensure that high solids can also be achieved. He sees great potential for RDC cows in mixed herds, but offers this reminder: “Be patient with first-lactation cows! The first lactation does not tell the whole story or the whole truth.”
Proof of these words can be found in one of his cows, Oikku, which has now calved five times and has produced a total of 85,000 kg ECM. After a good first-lactation performance of almost 12,000 kg ECM, she increased her production dramatically in her second lactation, reaching 15,000 kg ECM.
