Effects of climatic factors in poultry houses on egg production, egg weight and food consumption of commercial hybrid white layers



Effects of climatic factors in poultry houses on egg production, egg weight and food consumption of commercial hybrid white layers



Ankara Universitesi Veteriner Fakultesi Dergisi 33(1): 122-133



From Mar. to June, 152 hens were caged singly and 2848 hens were caged in groups of 4. Over the period, the ambient temp. averaged 20 degrees C (9 degrees -29 degrees ), RH 61% (39-99) and atmospheric pressure 783 millibars (748-789). The highest and lowest monthly egg production was 88% in Mar. and 83% in May (P<0.05) for singly-caged birds and 87% in Mar. and 78% in May (P<0.01) for group-caged birds.
