Özet
Bu çalışma karvakrol, timol ve rosmarinik asit içeren bitki ekstraktlarının etlik piliçlerde performans, sindirim kanalı histomorfolojisi ve kan parametreleri üzerine etkilerini incelemek amacıyla yapılmıştır. Çalışma, Tekirdağ Ziraat Fakültesi Zootekni Bölümünün deneme ünitelerinde gerçekleştirilmiştir. Ross 308 hibriti 192 adet bir günlük erkek civciv kullanılmış ve çalışma 21 gün sürmüştür. Çalışmada 3 muamele grubu oluşturulmuştur: 1) Bazal rasyon, 2) Bazal rasyon + 1 kg/ton karvakrol, timol ve rosmarinik asit ekstraktı, 3) Bazal rasyon + 2 kg/ton karvakrol, timol ve rosmarinik asit ekstraktı. Araştırma süresince hayvanlara yem ve su ad-libitum olarak uygulanmıştır. 23 saat aydınlık, 1 saat karanlık olacak şekilde ışıklandırma uygulanmıştır. Deneme süresince civcivler haftalık olarak tartılmış ve her hafta yemliklerde artan yem tartılarak haftalık yem tüketimi hesaplanmıştır. Araştırmanın 21. gününde her bölmeden birer hayvan olmak üzere toplam 24 hayvandan analiz için kan örneği alınmıştır. Kesimden sonra sindirim organları tartılmış ve histomorfolojik inceleme için bağırsak örnekleri alınmıştır. Çalışmada sindirimi destekleyen yem katkı maddesi olarak kullanılan bitki ekstraktının her iki dozunun etlik piliç performans kriterleri, ince bağırsakların histomorfolojik parametreleri, kan analiz bulguları ve sindirim organlarının ağırlıklarına istatistiki olarak önemli bir etkisinin olmadığı sonucuna ulaşılmıştır. Anahtar Kelimeler: broyler, karvakrol, timol, rosmarinik asit, aromatik ekstraktlar
This experiment was conducted to test the effects of an aromatic plant axtract consisted of carvacrol, tymol and rosmarinic asid on broiler performance, gut histomorphology and blood parameters. The study was realized in the broiler experimental unit of Department of Animal Science of Tekirdağ Agricultural Faculty and 192 one-day-old male Ross 308 strain broiler chicks were used. The experiment lasted for 21 days. Three treatments were consisted as the following; 1) Control group (basal diet), 2) Basal diet + plant extract (1 kg/ton feed) 3) Basal diet + plant extract (2 kg/ton feed) Each of 3 treatment had 8 replications to which 8 birds were randomly. Therefore birds were maintained in 24 battery brooders (3 tier wire cages) confined in an environmentally controlled experimental room. Feeds and water were offered freely. Experimentally diet was a typical broiler starter basal diet, containing mainly of maize and soybean meal. Lighting regimen was 1 h dark to 23 h light. Weight gain and feed intake of the chicks were determined by weighting the chicks in weekly intervals. At the end of the experiment one bird was randomly picked from each unit and kiled by cervical dislocation. Following dissection, proventriculus and gizzard were empited and washed through with tab water and weighted. All the removed organs and intestines were weighted and standardized according to 100 g body weight as well. Four cm ileal piece was cut from each empited and washed intestine to measure. Villus height, villus depth, crypt depth and lamina muscularis thickness. The results of the present experiment indicated that none of the supplemental level of plant extract affected broiler performance, gut histomorphology or immunal blood parameters. Key words: broiler, carvacrol, tymol, rosmarinic acid, aromatic plant extract
