Calls are growing for action against imports of cheap chicken from the United States which some claim benefit from state subsidies.
In particular, a type of chicken known as poulard -- young hens that have been spayed to fatten them -- are being targeted.
She Feng, general manager of Beijing-based Huadu Foodstuff, the biggest chicken provider for the Beijing 2008 Olympic Games, said: "They are too cheap. They are eating into our profits greatly."
China announced dumping and subsidy probes on chicken and auto products from the US on Sept 13, two days after US President Barack Obama imposed tariffs on tires from China.
Chinese industries complain that they're being hurt by "unfair trade practices", the Ministry of Commerce said on its website. The dumping investigation relates to poultry alone, a spokesman said in Beijing.
Ma Chuang, deputy secretary-general of the China Animal Agriculture Association, said investigations into the issue had been going on for nearly six months and the results were sent to the Ministry of Commerce formally in August.
"We did it on the basis of complaints from domestic companies and relevant investigations," said Ma.
