Members have accused Macau's Jockey Club of mismanagement, and reported that budget cuts have created real problems.
The allegations follow a Sunday Morning Post showing concern that Hong Kong's most successful racehorse, Viva Pataka, is now retired and living in a modest stable.
The claim has been rejected and concerns continue, according to a spokesman for the Macau Jockey Club.
Since 2004, there has been a fall in horse racing in terms of popularity as the club has not made a profit. Losses amount to 3.8 million patacas.
One of the main concerns raised is the shrinking number of top-class races held in Macau. The owners of racehorses say that because there are not enough events and many first-class horses cannot race for months, it will affect their performance in the long run. 바다이야기
The complaint confronted evidence pointing to substandard facilities. The Macau Derby winner Alfonso suffered a server injury earlier this month when a piece of concrete collapsed significantly in the club's stable.
Amanda Savage, a spokeswoman, said she had responded to members and had no further complaints. But Francis Tin, a member of the 19 who included his signature, said he had not received a response from the club.
The Jockey Club has re-applied to the government for a license and is still awaiting a decision.
