The measures would affect key provinces such as Hunan, Hubei, Shanxi, Jiangxi and Anhui where CP had earlier won contracts from Beijing to improve the farm sector.
The May 12 earthquake, measured at 8.0 on the Richter scale, killed an estimated 70,000 people and made millions homeless.
It also killed more than 12.5 million fowl and three million pigs, most of which had been raised in backyards.
The disaster has prompted the Chinese authorities to improve construction standards for buildings in rural areas.
Building codes were lax in rural areas, which increased the quake's death toll.
Damrongdej Chalongphuntarat, a vice-chairman of Chia Tai Group of Companies, CP's China arm, said the tougher standards would cover farms.
Any new building would be required to withstand earthquakes of 8.0 to 9.0 on the Richter scale, from 7.0 at present.
The improvement would stamp out small-scale farms in the future, giving way to medium-sized ones housing at least 1,500 pigs or 10,000 chickens, he said.
The quake has interrupted inland transport and significantly reduced consumption due to falling tourism. However, he was confident of quick rehabilitation in the affected area and nearby provinces, especially Sichuan, which has a population of 84 million.
Mr Damrongdej, who oversees CP's agro-industry operations in China's southwestern provinces covering Sichuan, Hunan, and Hubei, said that to support the restoration and cope with the expected stronger growth, the group planned to invest heavily in the areas by adding a chicken slaughterhouse and two animal-feed plants in the next two to three years.
On the long term, it would add a food-processing plant to add value to the products.
At present, CP's operations in southwestern China deal mainly with primary agricultural businesses, from animal feed to chicken farms, to cater to a market of nearly 260 million in Hunan, Hubei and Sichuan.
The operations produce around 1.48 million tonnes of animal and shrimp feed a year and raise more than 12 chicken per year.
According to Mr Damrongdej, the quake did not affect the group's animal-feed plants, chicken farm, seed plant, tea and winery operations, and its 2,000 staff were safe.
''Only 69,000 chickens died from the earthquake,'' he said.
He said he was confident that the operations would continue to thrive with a forecast of 15% sales growth over the year before.
CP expanded its business to inland China since 1983 after it has successfully set up businesses in other parts of China.
