(Medwell online, 2009) Demirel, Murat; Celik, Sibel; Temur, Cuneyt; Guney, Mehtap; Celik, Savas
This study was conducted to determine in vivo digestibility and fermentation property of various silages made of green herbage of Corn (C) and corn-soybean mixtures at different rates (90% corn + 10% soybean (90C10SB), 80% corn + 20% soybean (80C20SB), 70% corn + 30 soybean (70C30SB)). Each mixture was prepared at rates given above on fresh material basis and ensiled in 120 L plastic barrels (a total of 20, 5 replicate for 4 treatments) for 90 days. pH values of C silage were higher and acetic acid levels were lower than that of 80C20SB (p<0.05). Concentrations of lactic and propionic acid of corn-soybean mixture silages were found to be similar to C silage. Digestibility of DM, OM, ADF and NDF were higher in C silage than that of other silages, whereas digestibility of CP and EE of 80C20SB silage were higher than corn silage (p<0.05). It was concluded that ensiling corn with 20 or 30% soybean addition at green herbage basis generates desirable outcomes for fermentation properties and digestibility of crude nutrients.
The Effect of Molasses and Pre Fermented Lactic Acid Juice on Silage Quality and in Vitro Digestibility of Sugar Beet Pulp Plus Wheat Straw Silage
(Parlar Scientific Publications (p S P), 2018) Guney, Mehtap; Kale, Cagri; Temur, Cuneyt; Bingol, Nuriye Tugba; Aksu, Taylan
In the present study, the effect of some silage additives (molasses, pre-fermented lactic acid juice and their combination) on silage quality of sugar beet pulp+wheat straw mixture was investigated. For this purpose, 4 groups, each consisted of 6 replicates, were designed; 1) sugar beet pulp+wheat straw mixture (Control), 2) sugar beet pulp+wheat straw mixture plus 2% molasses (M), 3) sugar beet pulp+wheat straw mixture plus pre-fermented lactic acid juice (PFJ, 44.07x10(7) cfu/ml(-1) LAB) and, 4) sugar beet pulp+wheat straw mixture plus 2% molasses+pre-fermented lactic acid juice (M+PFJ). The silages prepared in 1 L glass jars were opened after 60 days. While the amounts of dry matter (DM), crude ash (CA), and neutral detergent fiber (NDF) of treated-silages were higher than those of the control group (P <0.05), crude protein (CP) levels were not affected by treatment. pH, Fleigh score (FS), and lactic acid amounts were not affected by additives. However, the addition of molasses and PFJ decreased the NH3-N concentration of the silages compared to the control group (P <0.05). The M+PFJ addition decreased the acetic and propionic acid concentrations of the silages compared to those of the control group (P <0.05). As a result, the addition of 2% molasses and/or PFJ to the sugar beet pulp+wheat straw mixture reduced the DM losses of silages and did not affect the silage fermentation parameters and, in vitro digestibility of dry matter (DMD) and organic matter of silages (OMD).
Energy Values of Maize Silages, Harvested and Ensiled at Different Seasons, With Nylon Bag and Enzymatic Methods
(Taylor & Francis Ltd, 2007) Temur, Cuneyt; Demirel, Murat
Energy values of maize silages harvested and ensiled at before silking (BS), silking (S), milk line (ML) and half milk line (HML) were determined by nylon bag and enzyme (pepsin-cellulase) methods. In the nylon bag technique, dry matter (DMD) and organic matter digestibility (OMD) of maize silages (60.02 and 65.63% BS stage) were reduced by advancing maturity stage. In the enzyme method, when DMD of maize silages (55.24% at BS stage) was reduced, OMD (42.20%) was increased by advancing maturity stage (P<0.05). Determined DMD and OMD values with nylon bag technique as well as digestible (DE), metabolizable (ME) and net energy for lactation (NEl) method were higher than the enzyme method (P<0.01). According to the linear regression analysis, relationships between two methods were nonsignificant. But the results of 2(nd) degree polynomial function regression analyses, all relationships were significant and the highest R-2 value was 0.63 for following equation: Nylon bag organic matter digestibility=62.79-22.99STAGE+0.014EME+3.99STAGE(2)-0.0001EME(2). Thus enzyme method could be used only at milk line for estimations of DMD, OMD, DE, ME and NE1.
