1. P, ZYE100 ve ZYE200 ile NKE100 ve NKE200 rasyonlarıyla besleme etlik piliçlerin 6. haftadaki canlı ağırlıklarını ve 0-6 haftalık dönemdeki canlı ağırlık artıĢlarını kontrol grubununkine nazaran önemli derecede artırmıĢtır. Buna karĢın tavukların 0-6 haftalık periyottaki yem tüketimleri deneme muamelelerinden önemli derecede etkilenmemiĢtir. Bununla beraber ZYE100, ZYE200 ve NKE200 rasyonlarıyla besleme tavukların yem değerlendirme sayılarını kontrol grubuna nazaran önemli derecede iyileĢmiĢtir.
2. NKE100 ve NKE200 rasyonlarıyla beslenen etlik piliçlerin serum HDL düzeyleri, ZYE200 rasyonunkiyle benzer ancak diğer muamele gruplarınınkine nazaran serum HDL düzeyini önemli derecede artırmıĢtır. ZYE200, NKE100 ve NKE200 rasyonları serum LDL düzeylerini diğer muamele gruplarına göre önemli derecede düĢürmüĢtür. 3. Toplam aerobik bakteri sayısı deneme muamelelerinden etkilenmezken, tüm muamele grupları kontrol rasyonuna nazaran ileum toplam koliform sayısını önemli derecede azaltmıĢtır. ÜÇE100 rasyonu hariç diğer tüm muamele grupları ileum E.coli sayısını KONT rasyonuna nazaran önemli derecede azaltmıĢtır. Etlik piliçler KONT, ÜÇE100 ve ÜÇE200 rasyonlarıyla beslendikleri zaman ileum laktobasillus sayısı diğer muamele gruplarınınkine nazaran önemli derecede azalmıĢtır.
4. ÜÇE100 ve ÜÇE200 rasyonlarıyla beslenen etlik piliçlerin sıcak ve soğuk karkas randımanları kontrol rasyonunkine benzer ancak diğer muamele gruplarınınkinden daha düĢük bulunmuĢtur.
5. Etlik piliçlerin etlerinin kuru madde içerikleri rasyon muamelelerinden etkilenmezken, ZYE200, ÜÇE100 ve NKE200 rasyonları etin ham protein içeriğinde önemli bir artıĢa yol açmıĢtır. Etin ham yağ içeriği NKE200 rasyonuyla artmasına rağmen, P, ÜÇE200, ZYE200 ve NKE200 rasyonlarıyla besleme etin ham kül içeriğini önemli derecede artırmıĢtır.
6. Sonuç olarak; mısır-soya küspesi esaslı etlik piliç karma yemlerine besi performansını olumsuz yönde etkilemeksizin doğal antimikrobiyal yem katkı maddesi olarak probiyotiğin yerine, 100 ve 200 ppm oleuropein temin edecek Ģekilde zeytin yaprağı ekstraktı ve 100 ve 200 ppm proantosiyanidin temin edecek Ģekilde nar kabuğu ekstraktı rahatlıkla kullanılabilir.
