Farklı Katkı Maddelerinin Leucaena leucocephala Silajının Bazı Kimyasal Parametreleri ve In Vitro Sindirilebilirliği Üzerine Etkileri

Öz

Bu çalışma, çeşitli katkı maddelerinin Leucaena leucocephala silajının fiziksel ve kimyasal özellikleri, yem değeri ve in vitro sindirilebilirliği üzerindeki etkilerini araştırmıştır. Araştırma, bir kontrol grubu ve sırasıyla %5 melas, %5 arpa ve %0.5 formik asit ile ilave edilen üç deneme grubundan oluşmuştur. Her grup sekiz tekerrürden oluşturulmuştur. Bitki materyali 2,5-5 cm boyutunda kesilmiş, ilgili katkı maddeleri ile işlenmiş ve vakumlanarak paketlenmiştir (200 g torba). 60 günlük silaj fermentasyon süresinin ardından, fiziksel özellikler, amonyak azotu, pH seviyeleri, besin kompozisyonu, yem değeri, in vitro ham protein parçalanabilirliği (IVHPP) ve in vitro sindirilebilirliği değerlendirmek için analizler yapılmıştır. DLG puanlarına göre (≥17.62±0.29), tüm gruplar yüksek kaliteli silaj sınıfında yer almaktadır. Uygulamalar yapısal olmayan besin maddelerini önemli düzeyde etkilemese de, %5 arpa grubunun ham kül içeriğinde önemli düzeyde bir artış gözlemlenmiştir. Leucaena silajına %5 melas ilavesi, ham selüloz (p<.005) ve asit deterjan fiber (p≤.001) düzeylerini önemli düzeyde azaltmış ve Flieg skorunu artırmıştır. Kuru madde tüketimi (KMT) dışında incelenen tüm yem değeri parametreleri %5 melas ilavesi ile önemli düzeyde artmıştır (p≤.001). Leucaena silajının metabolize olabilir enerjisinde önemli bir değişiklik gözlemlenmemiştir. %5 melas ilavesi, in vitro gerçek kuru madde sindirilebilirliği (IVGKMS) ve in vitro gerçek organik madde sindirilebilirliğini (IVGOMS) önemli düzeyde arttırmıştır (p≤.001), IVHPP'yi etkilememiştir. Sonuç olarak, bu çalışmada değerlendirilen silaj katkı maddeleri silaj kalitesini olumsuz etkilememiş ve %5 melas ilavesi en olumlu silaj kalite parametrelerini vermiştir.

Effects of Different Additives on Some Chemical Parameters and In Vitro Digestibility of Leucaena leucocephala Silage

Abstract

This study investigated the effects of various additives on the physical and chemical properties, feed value, and in vitro digestibility of Leucaena leucocephala silage. The experiment consisted of one control group and three treatment groups, which were supplemented with 5% molasses, 5% barley, and 0.5% formic acid, respectively. Each group included eight replicates. The plant material was chopped (2.5–5 cm), treated with the respective additives, and vacuum-packed (200 g per bag). Following a 60-day silage fermentation period, analyses were conducted to evaluate physical properties, ammonia nitrogen, pH levels, nutrient composition, feed value, in vitro crude protein degradability (IVCPD), and in vitro digestibility. According to DLG scores (≥17.62±0.29), all groups produced high-quality silages. While treatments did not significantly affect non-structural nutrients, a notable increase in crude ash content was observed in the 5% barley group. The addition of 5% molasses to Leucaena silage significantly reduced crude fiber (p<.005) and acid detergent fiber (p≤.001) levels, while also increasing the Flieg score. All feed value parameters except dry matter intake (DMI) increased significantly with the addition of 5% molasses (p≤001). No significant changes were observed in the metabolisable energy of Leucaena silage. The addition of 5% molasses significantly increased in vitro true dry matter digestibility (IVTDMD) and in vitro true organic matter digestibility (IVTOMD) (p≤.001), while it did not affect IVCPD. In conclusion, the silage additives evaluated in this study did not negatively affect silage quality, and the inclusion of 5% molasses yielded the most favorable silage quality parameters.
