Abstract
Study of the 90 and 305-day 2 X, mature equivalent, days open adjusted, milk production records of 74 animals with follicular cysts during their cystic lactation showed that they produced significantly more milk than their herd-mates (p <. 001 and p <. 01 for 90 and 305 days respectively). No significant difference in production was noted when cystic animals were compared with their identical herd-mates during their pre-cystic lactation. This indicated that the cystic cows were not higher producers before they become cystic, but that circumstances associated with the cystic condition appear to be responsible for increased production. It was found that the longer animals were cystic, the higher was their production and that the anestrous cystic animals had higher milk production than those with nymphomaniac tendencies.
