| Abstract | ||||
| This study was carried out through field survey of 209 chicken farms records of 10 broiler farms and 25 layer farms in different regions of Dakahlia province and Damietta province during the period extended from 2008-2018 . (110) cycles of broiler farms and the other 99 cycles were from layer farms. Records included broiler breeds as Ross, Cobb, Hubbard, Arbor Acres, Sasso and Shaver. Several layer breeds were used in the study as Lohman, Bovans and Fayumi. Data were collected, arranged, Summarized and then statistically analyzed using the computer program SPSS/PC+ ”Version 20”. This study was conducted to study the effect of air pollution on productive efficiency of broiler and layer farms. Regression analysis methods as stepwise , poisson and linear correlation were used to study the effect of chemical air pollution with ammonia and carbon dioxide on total production (total meat production / kg in broiler chicken and total egg production in layer chicken). The results showed that air pollution affect significantly (P < 0.05) on the total number of egg production by decreasing it about 19.7%. Meanwhile, air pollution had significant (P < 0.05) and negative correlation on total meat production. | ||||
