The study was conducted to compare the productivity performance of Layer breeder under conventional house and automatic house. Both houses were studied under small farms with an average of 250 birds. This study covered a period of 22 weeks with five replicates. Based on the results, the effect of different rearing systems on the mean body weight and FCR from week eighteen to forty weeks of age on weekly and cumulative basis were significantly (P<0.05) influenced among the various treatment groups in HH-260 birds. Egg production, Hen housed and hen day egg production in experimental birds in automatic rearing system was significantly different from birds reared in conventional rearing system. The study also concluded that ARS birds had better liveability as compared to birds under conventional rearing systems. Litter quality analyzed based on the proximate analysis and E. coli count and found significant (P<0.01) difference among the two-rearing systems. The proximate analysis of built up litter was significant higher (P<0.01) in CRS than the ARS. The higher proximate values like crude protein, crude fat, crude fibre, total ash and energy value were mainly due to feed wastage in conventional rearing system which leads to elevation of these values. There was highly significant difference (P<0.01) in working time measurement of automation over conventional system of rearing. It accepted the hypothesis of the study that ARS housing have better productivity and profitability over conventional, this is testified by the general better FCR, egg production, liveability and litter quality in CCS houses.
• Impact of rearing system on production parameters of layer breeders was studied.
• Automatic rearing system has significant influence on growth performance, egg production, liveability, litter quality and working time measurement.
