Assessing Yield and Silage Quality of Intercropped Corn and Soybean in Different Planting Patterns and in Mardin Ecological Condition
(Centenary University, 2021) Homan, E.; Zorer Çelebi, Ş.; Erdoğan, S.
This study was carried out to determine the effect of silage on fermentation quality. The silage was produced by forage yield of mixed planting of corn and soybeans which was planted as a second crop in Mardin ecological conditions. The field experiment was carried out in a Randomized Complete Experiment Design with three replications at 7 different planting ratios [corn (C), 70% corn + 30% soybean (70C30S), 60% corn + 40% soybean (60C40S), 50% corn + 50% soybean (50C50S), 40% corn +% 60 soybean (40C60S), 30% corn + 70% soybean (30C70S) and soybean (S)]. The single (pure) and mixed yield obtained from each plot were left to fermentation in glass jars for 90 days in four repetitions. According to the results of the study, the highest fresh biomass obtained was 71 071 and 68 333 kg ha-1 respectively from 60C40S and 70C30S mixtures, and the highest crude protein yield was obtained from 60C40S, 70C30S, 30C70S and 50C50S mixtures planting ratios. As the soybean ratio in the mixture increased, the CP ratio, silage pH and butyric acid (BA) concentration increased. While the lactic acid (LA) concentration of corn silage was the highest value with 2.67% in dry matter (DM), this value has been determined as 1.04% in soybean silage. To conclude, in regions having ecological conditions of Mardin province, it is recommended to mix planting with 30% or 40% ratio of soybean plant with corn plant to increase the protein value of corn silage and improve the fermentation of soybean. © 2021, Centenary University.

Determination of in Vitro True Digestibility and Relative Feed Values of Alternative Roughage Sources
(Centenary University, 2022) Örün, M.; Erdoğan, S.
The aim of this study was to compare chemical composition, relative feed values, and in vitro true digestibility of the giant fennel (Ferula communicus L.-F), helis (Prangos ferulacea L.-H), gum-tragacanth (Astragalus microcephalus WILD.-G) and leaves oak tree (Quercus robur L.-O), a naturally growing plant on the high-altitude plateaus of the Eastern Anatolia, with those of alfalfa. In vitro true digestibilities (IVTD) of roughages were determined with the Ankom DaisyII incubator. In terms of crude protein (CP) content, the lowest value was determined in H herb with 7.35 %, and the highest value was determined in alfalfa hay (A) with 19.28% (p<0.05). G hay had higher acid detergent fiber (ADF) and neutral detergent fiber (NDF) content and O leaves had higher ether extract (EE) and condensed tannin (CT) content. While the lowest IVDMD were found in G hay (42.91%) and O leaves (56.22%) with the highest cell wall structural components and CT content, the highest digestibility value was determined for F (70.47%) and A (71.60%) (p<0.05). Considering the analyzed parameters, it can be said that F hay is more suitable for ruminant feeding than other roughages. © 2022, Centenary University. All rights reserved.
May Citrus Extract Provide Anti-Giardial Therapeutic Efficacy
(Ataturk Universitesi, 2021) Aliç Ural, D.; Erdoğan, S.; Balikçi, C.; Ayan, A.; Erdoğan, H.; Ural, K.
In this study, it was aimed to investigate the therapeutic efficacy of the bitter orange extract in goat kids with giardiasis. A total of sixteen goat kids detected to be infected with Giardia duodenalis at the age of 12 to 68 days were enrolled in the study. Goat kids were randomly assigned into two groups, whereas goat kids in the control group (n= 8) without receiving any drug and group (n=10) received oral bitter orange extract at a dosage of 10 ml/goat kids for seven days. Anti-giardial therapeutic efficacy of bitter orange extract was determined by oocyst shedding interpreted with a microscopical examination of fecal samples on days 0 and 10. It was revealed that the therapeutic efficacy of orange bitter extract as compared with control was 99.9% on day 10. In conclusion, this significant decrease of oocyst shedding supports the anti-giardial activity of bitter orange extract and shows that it might be an alternative in the treatment of giardiasis. © 2021 Ataturk Universitesi.

Serum Thiol Disulphide Levels Among Sheep With Sarcoptic Mange
(Veteriner Fakultesi Dergisi, 2019) Çamkerten, İ.; Çamkerten, G.; Erdoğan, H.; Ayan, A.; Erdoğan, S.; Ural, K.
Sarcoptic mange, a notable parasitic disease, causes dermatological alterations among ruminants. Thiol-disulphite hemostasis is a novel oxidative stress parameter. The aim of this study was to evaluate dynamic thiol/disulfide homeostasis in sheep with sarcoptic mange. Total of thirty-six sheep (n=15 female, n=21 male) with sarcoptic mange (Group I), and twelve healthy sheep (Group II) were used in the study. A novel method was used to determine the thiol disulphide parameters. Native thiol, total thiol and Disulphide values were statistically lower in Group I. Disulphide/native thiol, Disulphide/total thiol, and Native thiol/ total thiol proportions had no statistical differences in groups. Sarcoptic mange was probably affected by the thiol Disulphide hemostasis in infected sheep. Thus, the data obtained in this study might form base for further studies to include antioxidant molecules in the treatment protocols. © 2019, Veteriner Fakultesi Dergisi. All rights reserved.
