Abstract
Bu çalışmada, çayırotu hasılına farklı oranlarda kekik posası ilave edilerek silolanmasının, silajların fiziksel kalite özellikleri, silaj fermantasyonu ve aerobik stabilite üzerine etkisinin belirlenmesi amaçlanmıştır. Çalışmada, ilk biçim çayırotu hasılına katkısız ve ağırlık esasına göre %3 ile %5 oranında kurutulmuş kekik posası ilave edilmiş ve 3 grup olacak şekilde silolanmıştır. Her bir grup için 6 adet olmak üzere toplamda 18 adet silaj örneği 1 l'lik cam kavanozlarda 60 gün süreyle fermantasyona bırakılmıştır. İki farklı oranda kekik posası katkısı, silajların KM içeriğini kontrol grubuna göre azaltmıştır (P<0.05). Kontrol ve kekik posası ilave edilen silaj gruplarından 2 ve 3. kaba yem kalite sınıfında silajlar elde edilmiş olup nispi yem değerleri ise 101.06 ile 106.55 arasında elde edilmiştir. Silajların fiziksel özellikleri sonucunda, katkısız silajlar 'memnuniyet verici' iken %3 ve %5 kekik posası katkılı gruplardan 'pekiyi' kaliteli silajlar elde edilmiştir. Çalışmada silajların pH düzeyleri 4.37-4.89 arasında belirlenmiştir. Silajların fermantasyon kalitesi incelendiğinde, kekik posası katkısı ile silajların LA miktarı önemli düzeyde azalırken, buna paralel olarak silajların AA ve BA düzeyleri de azalmıştır (P<0.001). Bunun yanısıra kekik posasının oranı %3'ten %5'e çıktıkça silajların aerobik stabilitesinin kontrol grubuna göre arttığı gözlenmiştir. Yapılan çalışma sonucunda kekik posasının silaj katkı maddesi olarak değerlendirilebileceği sonucuna varılmıştır.
In this study, it was aimed to determine the effect of ensiling by adding Oregano pulp at different rates to the meadow grass on the physical quality properties of silages, silage fermentation and aerobic stability. In the study, dried oregano pulp at the rate of 3% to 5% by weight basis and without additives was added to the first harvested of meadow grass and it was ensiled as 3 groups. A total of 18 silage samples, 6 for each group, were left for fermentation in 1 liter glass jars for 60 days. Addition of oregano pulp in two different ratios decreased the DM content of silages compared to the control group (P<0.05). Control and silage groups with added oregano pulp were obtained in 2nd and 3rd roughage quality class, and their relative forage values were between 101.06 and 106.55. As a result of the physical properties of the silages, silages without additives were obtained as 'satisfactory', while 'good' quality silages were obtained from the groups with 3% and 5% oregano pulp. In the study, pH levels of silages were obtained between 4.37-4.89. When the fermentation quality of the silages was examined, the LA concentrates of the silage decreased significantly with the addition of oregano pulp, while the AA and BA levels of the silages were also decreased (P<0.001). In addition, as the ratio of oregano pulp increased from 3% to 5%, it was observed that the aerobic stability of the silages increased compared to the control group. As a result of the study, it was concluded that oregano pulp can be evaluated as a silage additive.
