The Determination of Planting Density on Herbage Yield and Silage Quality of Jerusalem Artichoke (Helianthus Tuberosus L.) Green Mass
(KAFKAS UNIVERSITY, 2009) Karsli, M.A.; Bingöl, N.T.
The aim of this study was to determine green mass yield, silage quality prepared from green mass, nutrient content and digestibility of Jerusalem artichoke (Helianthus tuberosus L.) planted at varying planting densities. Experiment was designed as split plot with four replication and four different plant densities were tested. Planting densities were 70×50 cm (Control), 30×50 cm (Group I), 50×50 cm (Group II), and 85×50 cm (Group III). Chopped green mass were utilized as both silage prepared into 1 L jar-silo and dried original samples. pH of silages were 4.54-4.81 (P=0.5). Lactic acid, acetic acid, propionic acid, and ammonia-N levels were 2.12-4.30%, 1.97-2.32%, 0.29-0.41%, 0.82-1.14%, respectively (P<0.05). Dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), in vitro organic matter digestibility (IOMD), metabolic energy (ME) Mcal/kg values were 29.99-33.28% and 37.05-39.40%; 85.41-85.79% and 86.74-87.88%; 8.58-9.59% and 9.32-11.19%; 35.58-42.53% and 35.19-37.05%; 23.94-30.12%and 23.51-25.08%; 51.71-54.67% and 59.15-63.13%; 1.87-2.012% and 2.139-2.284% for silage and original samples, respectively. Dry matter yields of Jerusalem artichoke ranged from 297.3 to 768.1 kg/da (P<0.01). In conclusion, Jerusalem artichoke as an alternative feedstuff has a forage yield and nutrient content similar to high quality forage. Increasing planting density quadratically increased forage yield. The highest yield was obtained with 50×50 cm planting density. In general, Jerusalem artichoke silage has lower nutrient content, in vitro organic matter digestibility and energy value compared with original sample. Based on this data, Jerusalem artichoke green mass should be preferred to feed to animals as green forage, but can be fed to animals as silage if necessary.
The Effects of Sunflower Oil and Selenium Supplementation To Laying Hen Diet on Performance, Egg Quality and Egg Shelf Life
(Ataturk Universitesi, 2021) Kale, Ç.; Bingöl, N.T.
In this experiment; the effects of additions sunflower oil and/or inorganic (sodium selenite) and organic selenium (selenium-enriched yeast) to laying hen diet on performance, egg quality and egg shelf life were investigated. A total of 252 42-week-old Lohmann LSL white laying hens were randomly assigned to 6 experimental groups with 7 replications (6 chickens per repeat). Experimental pattern was created according to a factorial experiment plan designed according to 2×3 random plots. Six experiment diets were created by adding two different selenium (0.3 mg/kg) to both diets prepared with/without sunflower oil (3%). The experiment was continued for 12 weeks. Although no significant difference was observed between the groups in terms of egg production, feed consumption, feed conversion ratio, specific gravity, Haugh unit, albumen and yolk ratio in the experiment, significant differences were determined in egg weight, shape index, shell ratio, shell thickness, egg yolk color, albumen and yolk ratio (P<0.05). Egg yolk thiobarbituric acid reactive substances (TBARS) were higher (P<0.05) in group added only sunflower oil compared to other experimental groups. It was determined that selenium supplementation decreased TBARS value in groups fed a fatty diet (P<0.05). As a result; It was observed that the addition of sunflower oil and/or different sources of selenium to the laying hen diet did not affect performance and egg quality parameters in general; the addition of sunflower oil to the diet increased the egg yolk TBARS value, selenium supplementation prevented this increase and had favorable effects on egg shelf life. © 2021 Ataturk Universitesi.

Protective Effect of Subsieve Grape Extract (Vitis Vinifera L.) on Testes, Reproductive Hormones, and Some Spermatological Parameters in Heat Stress-Induced Rats
(Ataturk Universitesi, 2023) Koşal, V.; Avci, A.; Bingöl, N.T.; Keleş, Ö.F.; Kömüroğlu, A.U.; Okulmuş, Ç.
Heat stress (HS) has negative effects on reproductive parameters in male animals. This study was designed to investigate the protective effects of Vitis vinifera L., which has a natural antioxi-dant property, on reproductive parameters, testicular oxidative stress, reproductive hormones, and testicular histopathology in male rats treated with HS. Fifty male rats were divided into 5 different groups (control, HS, HS + 100, HS + 200, and HS + 300). It was determined that subsieve V. vinifera extract given at different doses eliminated the negative effects of HS administration on reproductive parameters. It was determined that V. vinifera increased sperm motility and density and decreased the rate of abnormal sperm regardless of dose (P <.001). It was determined that increased oxidative stress and decreased luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels as a result of HS administration improved in the extract-treated groups (P <.05), and FSH and testosterone levels increased in the HS + 200 and HS + 300 groups compared to the control group (P <.001). Histopathologically, it was determined that the degen-eration, edema, and congestion caused by HS disappeared due to the extract administration. As a result of this study, the protective effect of subsieve V. vinifera extract on HS on male reproductive parameters was revealed. © Author(s).
Relative Feed Value (Rfv) and Relative Forage Quality (Rfq) Used in the Classification of Forage Quality
(Ataturk Universitesi, 2016) Güney, M.; Bingöl, N.T.; Aksu, T.
The significant difficulties exit in both of providing and quality of forages which are an important part of ruminant rations. In addition to experienced these problems, there is no standard for the estimation of forage quality. In this case, affects the livestock economy negatively by increasing the cost of concentrate feed. For these reasons, it has been developed for Relative Feed Value (RFV) and Relative Forage Quality (RFQ) terms for the estimation of forage quality in recent years. RFV (Relative Feed Value) is an index, which is calculated by utilizing the ADF (Acid detergent fiber) and NDF (Neutral detergent fiber) which are plant cell wall components and consisting of single figure with the adoption of alfalfa as 100 at full bloom period. Relative forage quality index (RFQ), similar to the relative feed value, is instead based on the digestibility of fiber at calculation and is used to estimate the forage quality by using total digestible nurtients instead of digestible dry matter. The introduction and dissemination of RFV and RFQ based on animal performance in order to determine forage quality is an important for animal nutrition.
