Farklı Düzeylerde Beyaz Dut Posası ve Çayır Otu İçeren Silaj Karışımlarının In Vitro Değerlendirilmesi

Bu çalışma silolanan beyaz dut posası (BDP), çayır otu (ÇO) ve iki ürünün üç farklı oranda karışımlarının in vitro gaz üretimi (GÜ), organik madde sindirilebilirliği (OMS) ve enerji değerlerinin belirlenmesi amacıyla yapılmıştır. %100, 75, 50, 25 ve %0 BDP içeren BDP/ÇO karışım silajları ANKOMRF gaz üretim sistemi kullanılarak değerlendirildi. Silajlarda artan BDP seviyelerinin gaz üretimini artırdığı görüldü. BDP silajının OMS değeri tüm silajlar arasında en yüksek iken, ÇO silajının en düşüktü (%47.83). BDP/ÇO’nun 75:25 oranındaki karışım silajında diğer karışımlara göre daha yüksek ME, NEL ve OMD değerleri elde edildi. Sonuçlar OMS, ME, NEL ve selüloz olmayan karbonhidrat değerleri ile GÜ-24 sa arasında pozitif korelasyonun olduğunu gösterdi (r=0.981, r=0,966, r=0.981 and r=0.957, sırasıyla). Çalışmanın sonuçları, BDP100/ÇO silajının OMS ve enerji değerlerinin diğer silajlara göre daha yüksek olduğunu göstermiştir. Ayrıca BDP’nın farklı oranlarda ÇO ile silolanması, BDP/ÇO silajlarının OMS ve enerji değerlerinde artışa neden olacağından BDP/ÇO silajı gibi geleneksel olmayan silajların rasyonlara dahil edilmesi hayvansal üretim maliyetinin düşürülmesine katkı sağlayabilir.

An In Vitro Evaluation of the Silage Mixtures Containing Different Levels of White Mulberry Pomace and Meadow Grass

This study was conducted to determine the in vitro gas production (GP), organic matter digestibility (OMD), and energy values of ensiled white mulberry pomace (WMP), meadow grass (MG), and the mixtures of the two crops at three different ratios. The silages in WMP/MG mixtures containing 100, 75, 50, 25, and 0% WMP were evaluated by using of ANKOMRF GP system. It was observed that increasing levels of WMP in the silages enhanced GP. Whereas the OMD value of WMP silage was highest (53.27%) among all silages, MG silage was the lowest (47.83%). Higher ME, NEL, and OMD values were obtained in WMP and MG mixture silage at a ratio of 75:25 compared with the other mixtures. The results indicated that the OMD, ME, NEL, and non-fiber carbohydrate values were positively correlated with GP-24 h (r=0.981, r=0.966, r=0.981, and r=0.957, respectively). The results of the study showed that the OMD and energy values of WMP100/MG silage were higher than the other silages. In addition, since ensiling of WMP with MG at different ratios will be resulted in increases in OMD and energy values of WMP/MG silages, incorporating unusual silages like WMP/MG silage into diets may provide a benefit to reduce in cost of livestock production.
