Effect of urea or urea plus molasses supplementation to silages with different sorghum varieties harvested at the milk stage on the quality and in vitro dry matter digestibility of silages

Öz:

Bu araştırmanın amacı süt olum döneminde hasat edilen dört farklı sorgum varyetesinden (Grass 11, Grazer, Gözde ve P-988) elde edilen silajlara % 0,5 üre veya % 0,5 üre ve % 4 melas katkısının etkilerini belirlemektir. Bitki materyalleri 1 kg'lık kavanozlarda silaj yapılmış ve silajın kimyasal bileşim, pH, organik asitler, iv vitro sindirilebilirlik (1VDMD) ve sindirilebilir kuru madde verimleri (DDMY) tespit edilmiştir. Silaja üre veya üre ve melas katkısı ham protein oranını önemli derecede (P < 0,01) artırmıştır. Bununla birlikte, üre ve melas katkısı silajın NDF ve ADF içeriğini önemli derecede azaltmıştır. Ayrıca katkı maddeleri silajın pH değerini artırmıştır. Silaja üre veya üre ve melas katkısı genellikle sorgum silajlarının asetik ve propiyonik asit içeriğini etkilememiştir. Bununla birlikte üre veya üre ve melas gruplarının bütirik asit içeriği kontrol gruplarından daha yüksek olmuştur. Bütün sorgum çeşitlerinin in vitro kuru madde sindirilebilirliği üre veya üre ve melas katkısıyla azalmıştır. Katkılar (üre veya üre ve melas) sindirilebilir kuru madde verimini etkilememiştir. Sonuç olarak, süt olum döneminde hasat edilen sorgumlardan elde edilen silajlara % 0,5 üre veya % 0,5 üre ve % 4 melas katkısı silajın protein içeriğini iyileştirmiştir, ancak silaj kalitesi, in vitro kuru madde sindirilebilirliği ve sindirilebilir kuru madde verimi üzerine pozitif bir etki yapmamıştır.

The objective of this study was to evaluate the effects of 0.5% urea and 0.5% urea plus 4% molasses (on weight basis) addition to sorghum silages ensiled using 4 sorghum varieties (Grass II, Grazer, Gözde, and P-988) harvested at the milk stage. Plant materials were ensiled in 1-kg jars and the chemical composition, pH, organic acids, in vitro digestibility (IVDMD) and digestible dry matter yield (DDMY) of the silages were determined. Addition of urea and urea plus molasses to silages increased the crude protein ratio significantly (P < 0.01). However, the addition of urea plus molasses significantly decreased the neutral detergent fiber and acid detergent fiber contents of the silages. Additives significantly increased the pH values of the silages. The addition of urea and urea plus molasses to silages generally did not affect acetic or propionic acid content; however, the butyric acid content of the urea and urea plus molasses groups was higher than that of the control groups. IVDMD of all sorghum varieties decreased with the addition of urea and urea plus molasses. Additives did not affect DDMY. In conclusion, the addition of 0.5% urea and 0.5% urea plus 4% molasses to sorghum silages, harvested at the milk stage, improved the CP content of the silages, but they had no positive effect on silage quality, IVDMD or DDMY.
