Abstract
At presenı study 320 Babcock-B-380 brown hens aged 32 week were used. This experiment was carried oul to delermine eHects ol leeding laying diets supplemenled with dillerent lavels ol Clinut-looo (O, 1.5,2.5 and 3.5%) on their leed intake, leed ellieieney, egg production. egg weight, damagad egg raıio and specific gravity. The experiment was lasted in 90 days. At the end of Ihe experiment egg production was found lo be 90.76, 92.10, 91.62 and 90.61 %, respectively (P>0.OO5). Feed intake was observed lo be 135.44, 135.12, 129.09 and 129.25 g, respectively (P>0.05). While the towest feed ellicianey (2.29) was obtained in the group led 3.S % zeolit, the higheSI feed effieiency (2.40) was oblained in the group feed O % leolit (P>O.OS). There were no dillerences between the groups in terms of e99 weight and specific gravily (P>0.05). Middle of the experiment. while the lowest ralio for damaged e99(I%) was obıained in Ihe group led 1.5 % leolit-l 000, the highesl ratio for damaged egg (1.31 %) was oblained in the group led O % leolit AI Ihe end ol Ihe experiment, raıio ol damaged egg was delermined lo be 0.94, 0.78, 1.19 and 1.05 %, respeclivety. Consequently, use of levels of 2.5 and 3.5 % leolit in poultry diels was concluded to effect on feed conversion in a positive manner due lo reduced leed intake without any reduction on egg production although differences showed no significance
Özet
Bu çalışma 32 haftalık yaşta toplam 320 adel Babcock·B-380 kahverengi yumurtacı tavuk kullanılarak yürülOldO. DM gruba ayrılan tavukların rasyonlarına % O. 1.5.2.5 ve 3.5 düzeylerinde ilave edilen zeolitin (Clinut-l000) günlük yem tuketimi. yemden yarananma oranı, yumurta a Jırlığl, hasanı yumuna miktarı ve spesifik graviıe üzerine etkileri belirlendi. Deneme 90 gOn surduruldO. Deneme sonunda yumurta verimleri sırasıyla % 90.76, 92,10, 91,62 ve 90.61 olarak bulundu (P>O.05). GunlOk yem ıoketimleri sırasıyla 135.44, 135.12, 129.09 ve 129.25 g olarak tespil edildi (P>O.OS). Bir kg yumurta verimi için tüketilen yem mikları % 3.5 leolit içeren rasyonla beslenen grupta en dOşük (2.29 kg) olur1O.OS). Yumurta ağırlığı ve spesifik gravite bakımından gruplar arasında istatistiksel farklılık gözlenmemiştir (P>O.OS). Deneme ortasında en yuksek hasarlı yumurta oranı (% 1.31) kontrol grubundan elde edilir1
