Effects of pattern systems on production performance and egg quality of laying hen
The objective of the study was to evaluate the effects of pattern raising systems on production performance and egg quality of laying hens. One hundred twenty laying hens and 30 weeks of age were used in completely randomized design (CRD). The study was divided into 2 patterns: 1) conventional battery cage pattern; and 2) floor pen pattern. The conventional battery cage pattern had dimension of 30 × 40 × 37 cm with 2 laying hens each while in floor pen pattern was 5 m2 with 10 laying hens each. Each treatment had 10 replicates (120 laying hens). All laying hens were provided with the same diet during 30 days of experimental period. The results showed that the laying hen pattern systems affected to egg production performance and egg quality. Feed intake and egg production of laying hens in the conventional battery cage pattern were significantly higher than those in the floor pen pattern (p<0.05). However, hens in floor pens showed better results of feed conversion ratio, egg weight and Haugh unit than those from conventional pattern (p<0.05).
