Farklı mevsimlerde kafes seviyesinin yumurtacı tavukların performans veyumurta kalite özellikleri üzerine etkisi

Bu araştırma, mevsime bağlı olarak kümes-içi çevre şartları değişikliklerini ve farklı mevsimlerde kafes seviyesininyumurtacı tavuklarda performans ve yumurta kalite özellikleri üzerine etkisini belirlemek amacıyla yürütüldü. Araştırmada,288 Lohman Beyaz yumurtacı tavuk 3 farklı kata (Ü = üst, O = orta, B = alt) eşit sayıda dağıtıldı. Bir yıl süre ile yapılanölçümlerle, mevsime bağlı olarak kümes içi hava kalitesi ve sıcaklık değerlerinde meydana gelen değişimler gözlendi. Yaz mevsiminde düşük seviyede seyreden CO2, NH3 ve H2 S seviyeleri kış mevsiminde yükselmiş ve kümes içi bağıl nem arttı. Kışve sonbahar mevsimlerinde Ü katların (P

Effect of tier level on the performance and egg quality traits of laying hens in different seasons

The aim of the present study was to determine the influence of tier level on the performance and egg quality traits of laying hens in different seasons. A total of 288 Lohmann hens were used and placed into 3-tier cage (T=top, M=middle, B=bottom). The measurements obtained herein for 12 months showed that the air quality and temperature changed depending on the season. Sure enough, as the outdoor temperature of poultry houses lowered in the winter season, the indoor temperature of poultry houses decreased. The lower values of CO 2, NH3 and H2S of poultry houses in the summer increased in winter season, and also the relative humidity increased. While the egg production of hens caged at the T tiers was higher (P
