Özet
Bu araştırma, mısır yerine farklı seviyelerde tritikale kullanılan yemlerde enzim kullanılmamasının etlik piliçlerin verim performansı üzerine nasıl bir etki yaptığını belirlemek için yapılmıştır. Cinsiyet ayrımı yapılmış 1 günlük yaşta toplam 960 adet Ross 308 (480 erkek ve 480 dişi) etlik civciv materyal kullanılmıştır. Deneme, 4 oda içinde 3 yem muamelesi 4 tekerrürlü olmak üzere toplam 48 alt grupta yürütülmüştür. Yemler başlangıç (%23 HP ve 3000 Kcal/kg ME), büyütme (%21 HP ve 3175 Kcal/kg ME) ve bitirme yemi (%20 HP ve 3225 Kcal/kg ME) olarak hazırlanmıştır. Besleme dönemleri sırasıyla 0-11., 12-28. ve 29-42. günlerde ve %100 mısır (M, kontrol) ve %100 tritikale (T) ile mısırtritikale (MT) gruplarından oluşmuş ve sırasıyla dönemlere göre mısır ve tritikale gruplarında %50, 55 ve 58 oranlarında; MT guruplarında ise % 25, 27.5 ve 29 oranlarında tritikale ve mısır karışımı kullanılmıştır. Yemlere fitaz dâhil hiçbir enzim eklenmemiştir. Canlı ağırlık (CA) yem tüketimi (YT), yem değerlendirme katsayıları (YDK) ve yaşama gücü ölçümleri haftalık olarak yapılmıştır. Çalışmada, enzim ilave edilmeden mısır yerine tritikale kullanımının etlik piliçlerin verim performansı (CA, YT ve YDK) üzerine etkisi önemli bulunmuştur (P0.01). Deneme sonu M grubunun (kontrol) CAsı (2042.47) T grubundan (1304.56) %36; MT gurubundan ise (1908.82) %6.5 daha ağır bulunmuştur. Deneme sonu YT ve YDKlar sırasıyla M grubunda (4089.29; 2.24 ); T grubunda (2584.38; 2.20); MT gurubunda ise (3627.0; 1.89 ) bulunmuştur. Yaşama gücü, muamelelerden etkilenmemiştir. Etlik piliç yemlerine fitaz dahil hiçbir enzim kullanmadan %50-58 oranında tritikale ilavesi sonucunda ilk 4 hafta içinde çok önemli gelişme gerililikleri görülmüştür. Etlik piliçlerden optimum verim alabilmek için tritikale fitaz dahil başka bir enzim ilave edilmeksizin ilk 4 hafta içinde tek başına yemlere karıştırılması tavsiye edilmemelidir. Ancak, broyler yemlerinde hiç enzim kullanılmamış olsa bile, tritikalenin %50 oranında mısır ile yarı yarıya karıştırılarak verilmesi durumunda mısırın ilk 4 hafta içinde tritikale kullanımından kaynaklanan gelişme geriliklerini telafi edebilecek potansiyele sahip olduğu kanaatine varılmıştır.
This research was carried out to determine the effects of different levels of triticale replacement instated of corn without any enzymes on growth performance of broiler chicks. In this experiment, total 960 day-old, sexed Ross 308 broilers (480 males and 480 females) were used. This experiment was conducted total 48 groups in 4 rooms with 12 floor pens with four replicates for 3 feed resources. Starter (23% CP and 3000 kcal ME/kg of feed), grower (21% CP and 3175kcal ME/kg of feed), and finisher diets (20 CP and 3225 kcal ME/kg of feed) were provided from 0 to 11, from 12 to 28, from 29-42 days of age respectively. Broilers were fed diets containing either maize (as a control group-M) or triticale grain as the sole source (T) and corntriticale (MT). M and T groups were provided starter, grower and finisher diets % 50, 55 and %58 and MT group was 25%, 27.5, and 29% respectively. No enzyme added to diets phytase included. Body weight (BW), feed consumption (FC) feed conversion ratio (FCR), and survival rate measurements were made on a weekly basis. It was found that there were significantly differences between M,T, and MT groups of BW, FC and FCR for broilers at the end of trail. BW of birds fed M were %36 and %6 heavier than that fed T and MT groups respectively (P<0.01). The FC and FCR M, T and MT groups were (4089.29; 2.24 ); (2584.38; 2.20); (3627.0; 1.89 ) respectively at the end of the trail (P<0.01). Livability was not affected by M, T and MT groups treatments. Supplementation of triticale by 50-58% for broilers diets within the first 4 weeks without any kind of enzyme including phytase showed significantly growth retardation. To obtain optimum efficiency from broiler chicks, triticale shouldn't be mixed to feeds as an alone as a feed source without any kind of enzyme including phytase in the first four weeks. However, It was concluded that maize will able to have compensating potential for the growth retardation in case use of mixed half and half with triticale 50% corn for the first 4 weeks even though no enzyme used in broiler feed.
