The Effect of Cage System and Stocking Density on Performance, Egg Quality and Microbial Load of Eggshell of Laying Hens
This study was carried out to determine the effects of two different cage systems (enriched and conventional) and low and high stocking densities on performance, egg quality and egg shell microorganisms. In study, two different genotypes were used to native (Atak-S) and foreign (Lohmann) hens occurr...

| description | This study was carried out to determine the effects of two different cage systems (enriched and conventional) and low and high stocking densities on performance, egg quality and egg shell microorganisms. In study, two different genotypes were used to native (Atak-S) and foreign (Lohmann) hens occurred of 864 hens used. As the cage system, the battery type was used in the conventional system and the enriched cage type was used in the alternative system. The results indicated that genotype and cage system significantly affected egg production and egg mass in the laying period (18-76 weeks). It was determined that Lohmann genotype and conventional cages had significantly higher egg production and egg mass in this period. It was seen that hens consumed significantly higher feed in enriched cages than in conventional cages, and were significantly better feed conversion ratio in low stocking density compared to high stocking density. The effects of genotype and cages system on the quality characteristics of eggs were found to be significant, and it was determined quality characteristics of Lohmann eggs were better (especially eggshell quality. In addition, it was understood that the internal quality of the eggs in the conventional cages and the external quality characteristics of the eggs in the enriched system were positively affected. The total numbers of microorganisms were determined to be higher on shell of eggs from enriched cages than conventional cages. The total numbers of microorganisms were higher in enriched cage eggs compared to conventional cage eggs. However, stocking density was not a significant effect on the microbial load of the eggshell. |
