    Assessment of nutritive value, gas and methane production, fermentation of ensiled mixtures of sorghum-cluster bean
    (Taylor & Francis Ltd, 2023) Ciftci, Beyza; Kaplan, Mahmut; Akcura, Mevlut; Beyzi, Selma Buyukkilic
    This study was conducted to investigate the effects of different mixture ratios of sorghum (S) and cluster bean (CB) on fermentation parameters, nutritional composition, and gas-methane production of mixture silages. Five different mixture ratios (100%S, 75%S+25%CB, 50%S+50CB, 25%S+75%CB and 100%CB) were used in this study. Effects of mixture ratios on entire parameters were highly significant (p <= 0.01). Decreasing ADF and NDF ratios and increasing crude protein, ash and oil contents and condensed tannin levels were observed with increasing cluster bean ratios of the mixtures. However, cluster beans reduced WSC and lactic acid and increased pH, butyric acid and ethanol contents. The lowest Fleig score was obtained from cluster bean silage (100%CB). The lowest gas-methane production was obtained from cluster bean silage and the greatest ME and NEL values were obtained from sorghum silage (100%S). The best OMD values were obtained from sorghum silage and 75%S+25%CB mixture silage. The present findings revealed that a 50%S+50%CB mixture yielded high nutritional composition and good fermentation parameters.

    Effects of Irrigation Levels on Biochemical Traits of Popcorn Kernels
    (Springer Science and Business Media Deutschland GmbH, 2023) Kaplan, Mahmut; Taş, İsmail; Ciftci, Beyza; Varol, İhsan Serkan; Akçura, Sevim
    Popcorn, directly consumed as foodstuff, is among the most popular products. Biochemical quality traits of popcorn may exhibit significant variations based on growing conditions. Number of studies about the irrigation-dependent changes in biochemical traits of popcorn kernels is quite limited. This study was conducted to determine the effects of different irrigation levels (50%, 75%, 100% and 125% of depleted water from the field capacity) on protein characteristics (crude protein and pepsin protein digestibility), starch characteristics (total starch, resistant and non-resistant starch, amylose-amylopectin content), oil and fatty acids and mineral contents of popcorn kernels. Experimental results were assessed through variance and biplot analyses. Irrigation levels had highly significant effects on biochemical traits of popcorn kernels. Irrigations increased kernel protein and starch contents and decreased dietary fiber and amylose contents. Linoleic acid contents increased and oleic acid contents decreased with increasing irrigation levels. The greatest palmitic and stearic acid contents were obtained from I100 treatments. Na and Fe contents increased with increasing irrigation levels. The greatest Mg and Zn contents were obtained from I100 irrigation level and the greatest Ca content was obtained from I75 irrigation level. In present biplots generated for visual assessment of the changes in investigated traits with irrigation levels, oleic acid, amylopectin and dietary fiber contents were placed into the same sector with I50 treatment; Zn, stearic acid, palmitic acid and Mg contents were placed into the same sector with I100 treatment; the other traits were placed into the same sector with I125 treatment. Two principle components (PC1 and PC2) explained 96.55 of total variation indicating significance of investigated traits based on irrigation levels. It was concluded based on present findings that biochemical traits, fatty acid composition and mineral contents of popcorn kernels could be improved through the use of different irrigation levels and irrigation levels should be arranged based on soil conditions to improve quality traits of popcorn kernels.

    Evaluation of silage quality characteristics and nutritive value of oat genotypes
    (Springer, 2024) Kaplan, Mahmut; Akcura, Mevlut; Kardes, Yusuf Murat; Beyzi, Selma Buyukilic; Ciftci, Beyza; Kokten, Kagan
    This study aimed to determine the silage characteristics of oat lines developed through a rigorous 10-year selection process. During this period, 100 plants with high biomass yield were meticulously chosen from oat lines obtained from the Louisiana State University gene bank. Researchers designed experiments using an incomplete randomized block format across two growing seasons: 2014-2015 and 2015-2016. Oat plants were carefully harvested at the milk stage, chopped into pieces using a specialized plant chopper, and ensiled in plastic vacuum bags for subsequent analysis. The samples were then stored at room temperature for a period of 60 days. The comprehensive analysis conducted over this two-year research period revealed significant variations in the silage yields of the genotypes, ranging from 5.71 to 24.42 t ha-1. Moreover, notable variations were observed in the content of crude ash (ranging from 3.952 to 9.380%), ADF (ranging from 27.899 to 40.782%), NDF (ranging from 40.688 to 63.999%), crude protein (ranging from 6.673 to 11.470%), dry matter (ranging from 14.954 to 41.817%), pH levels (ranging from 3.812 to 5.668), in vitro gas production (ranging from 49.793 to 67.847 ml), methane production (ranging from 15.036 to 18.442 ml), as well as concentrations of acetic acid (ranging from 0.000 to 0.144%), lactic acid (ranging from 1.974 to 2.599%), butyric acid (ranging from 0.000 to 0.064%), and propionic acid (ranging from 0.000 to 0.306%). The study clearly indicated that many oat lines showed promising silage properties. Consequently, it is inferred that the utilization of high-yield lines in silage production holds considerable potential in providing a valuable feed source for livestock.
