What diet is best in late lactation dairy cows?
Teagasc recently highlighted the results of its research examining which diet is best for late lactation dairy cows.
Teagasc researchers investigated offering different supplementary feeds to grazing dairy cows in late lactation.
In an experiment conducted at Teagasc Moorepark from October to mid-November in 2013 spring-calved cows were randomly assigned to one of six treatments.
Results from four of the treatments are reported here, the additional two treatments involved lower grass allowances and high levels of supplementation.
The four treatments reported are:
(1) high grass allowance (17kg DM/day);
(2) low grass allowance (14kg DM/day)
(3) 14kg grass DM plus 3kg DM concentrates
