Özet
Bu çalışma, yumurtacı tavuklarda biberiye (Rosmarinus officinalis L.) uçucu yağının bazı kan parametreleri ve jejunum bakteri içeriği üzerindeki etkilerini, antibiyotik (klortetrasiklin) ve E vitamini (?-tokoferol asetat) ilaveli yem grupları ile karşılaştırmalı olarak belirlemek üzere yapılmıştır. Çalışmada 32 haftalık yaşta 240 adet Bovans genotipi beyaz yumurtacı tavuk (5 tekrarlamalı ve her bir tekerrür grubunda 8 tavuk olmak üzere), 6 ana gruba ayrılmıştır. Gruplardan biri standart bazal yemle beslenirken, diğerleri aynı yeme 500 mg/kg antibiyotik, 200 mg/kg E vitamini, 100, 200 ve 300 mg/kg biberiye uçucu yağı içeren karma yemlerle 90 gün süreyle beslenmişlerdir. Karma yeme ilave edilen katkıların incelenen kan parametreleri üzerine herhangi bir etkisi saptanmamıştır. Ancak antibiyotik ve biberiye uçucu yağının tüm dozları bağırsak jejunum bakteri içeriğini etkilemiş ve muhtemel koliform, fekal koliform, Escherichia coli (E. coli) ve Clostridium perfringens (Cl. perfringens) bakterilerini önemli düzeyde düşürmüştür. Biberiyenin 100 mg/kg uçucu yağ dozu, incelenen tüm bakteri türlerinde, antibiyotik ile aynı etkiye sahip olurken, 300 mg/kg doz uygulamaları muhtemel fekal koliform 200 ve 300 mg/kg dozların ise E. coli üzerinde antibiyotikten çok daha etkili olmuştur. Sonuç olarak biberiye uçucu yağının yüksek antimikrobiyal etkiye sahip olduğu ve bazı patojen bakterilere karşı koruyucu olarak yumurtacı tavuk karma yemlerinde kullanılabileceği söylenebilir.
This experiment was designed to investigate the effects of antibiotic, vitamin E and rosemary essential oils in various doses on some blood parameters, beneficial and harmful microorganisms in instentine jejunum microflora of lying hens. The experiment was conducted according to random parcel experiment design. A total of 240 Bovans genotype and 32 weeks aged were equally divided into 6 groups (8 hens in each group with 5 replicates). While the control group was fed with basal diet the treatment groups were supplemented with 500 mg/kg antibiotics; 200 mg/kg vitamin E; 100, 200, and 300 mg/kg REO to basal diet for 90 consecutive days. The result showed that there were no effects of all additions to basal diets on examined blood parameters. Antibiotic and all rosemary essential oils doses to basal diet affected the instentine jejunum bacteria content by decreasing probable coliforms, faecal coliforms, Escherichia coli (E. coli) and Clostridium perfringens (Cl. perfringens) bacteria level significantly. While a 100 mg/kg rosemary essential oils dose was of the same influence with antibiotic (500 mg/kg) on all bacteria species, 200 and 300 mg/kg doses applications were more effective on E. coli compare to antibiotics. 300 mg/kg doses applications dose was more effective on probable faecal coliforms than antibiotics. As conclusion, the results shows the rosemary essential oils has the high antimicrobial effect on some pathogenic bacterias and could be used in laying hen for feed addition.
