Abstract：Taking layer industry as an example, survey data from scale breeding farmers of layer in China￠s five major egg production provinces was used, from the perspective of layers￠ fecal disposal, with both methods of Super-SBM model and quintile regression, empirical analysis was done on the environmental efficiency in layers￠ scale breeding and its influence factors. The results show that: the environmental efficiency of layers￠ scale breeding was lower than its technical efficiency. Moreover, the environmental efficiencies vary in different regions. There are phenomena of input redundancy and insufficient desirable output as well as excessive undesirable output during breeding process. Mechanization and high-frequency in fecal cleaning are in favor of maintaining a high level of the environmental efficiency in layers￠ scale breeding, while the usage of fecal does not have continuous significant influence. The promotion of scale and standardized breeding in China is good for improving the environmental efficiency in layers￠ scale breeding.
