Research by Teagasc has shown that early nutrition is critical for high fertility and embryo survival in replacement heifers.
Early embryo loss is the major cause of reproductive failure in heifers and cows.
The effects of short-term changes in energy intake pre and post-insemination on embryo survival, have been investigated at Teagasc Athenry in beef heifers.
Embryo survival trial
The heifers were split into two groups consisting of a low-nutrition treatment and high-nutrition treatment.
The low-nutrition treatment was a grass allowance equivalent to 0.8 times maintenance, while the high-nutrition treatment was a grass allowance equivalent to twice maintenance.
The groups were then spilt into two sub-groups with half of the heifers in the low-nutrition treatment moving to the high-nutrition treatment after breeding.
