The present study had 2 primary hypotheses. Our
first hypothesis was that increasing LH during an ovarian
superstimulation protocol would increase the ovulation
rate but may reduce embryo quality. Second, we
hypothesized that acute feed restriction (25%) during
superstimulation would not alter ovulation rate but
would increase embryo quality. Of particular importance,
we proposed that an important interaction could
occur between these 2 treatments with increasing LH in
the FSH preparation, potentially leading to increased
embryo yield in feed-restricted cows but potentially
having a negative effect in cows fed ad libitum.
