2023
Nalan Yazıcıoğlu
The objective of this research was to examine the impact of fenugreek gum and eggplant peel extract on multiple characteristics of rice pudding, encompassing parameters such as total soluble solids content, pH, color, syneresis index, storage stability, total phenolic content, antioxidant activity, flavonoid, and anthocyanin content, along with a sensory evaluation using a 5-point hedonic scale. Different concentrations of fenugreek gum (0%, 0.2%, 0.4%) and eggplant peel extract (0%, 0.25%, 0.5%) were prepared and incorporated into the rice pudding formulation at varying levels. Higher concentrations of fenugreek gum and eggplant peel extract in the pudding resulted in improved syneresis percentage (68.25±0.42%). This result shows reduced water release and improved storage stability. The addition of fenugreek gum also positively associated with increased storage stability, while eggplant peel extract had no significant effect. Furthermore, while the content of monomeric anthocyanins, total phenolics, total flavonoids, and antioxidant activity in the rice pudding samples increased with higher concentrations of eggplant peel extract, consumer acceptance scores were reported to be very low.

Fish consumption choices are impacted by the socioeconomic aspects of customers. A field survey was done in 2022 with the purpose of (i) measuring the frequency of fish consumption, (ii) studying the socioeconomic characteristics of customers and their preferences; and (iii) researching the variables impacting the consumption of fish by consumers in the Siraha district. A sample size of 102 individuals was selected randomly from the Siraha district, including the Lahan Municipality, Dhangadhimai Municipality, and Golbazar Municipality, to ensure representation across diverse socio-economic backgrounds. Data was collected using a questionnaire administered to the participants. Respondents (58.8%) overwhelmingly prefer to eat fish more than twice a week, throughout the year or particularly in winter. Rohu (Labeo rohita) and carp (Cyprinus carpio) are the most often eaten fish species. The frequency of fish-consumption shows a strong connection with income level and education level. The stepwise multiple regression model explained 58.1% of the overall variation in fish consumption. The market structure is not sanitary, the price of fresh fish is expensive, and the consumption frequency of customers is impacted, particularly for poor socio-economic groups. boosted by a variety of various legislation, marketing, and advertising methods. In addition, consumers should be dispersed throughout the year rather than exclusively in particular seasons.

Kefir is a fermented product obtained from goat, sheep and cow milk as a result of lactic acid and ethyl alcohol fermentation. In this study, it was aimed to investigate the possibility of producing an alternative functional kefir product from almond milk. It was enriched with banana and honey to improve its sensory properties. Samples were stored at +4oC for 14 days. The pH and dry matter of samples containing almond milk were lower than those containing cow’s milk. Serum separation increased with the increase of almond milk ratio. The use of banana increased dry matter and viscosity, and decreased serum separation. pH, dry matter and viscosity decreased during storage. The highest L* value was observed in the control kefir produced from 100% cow’s milk, and the lowest in the samples containing honey and banana on the 1st day of storage. It can be said that the addition of honey increases the b* value and the addition of banana decreases the b* value. As almond milk ratio and storage time increased, bacteria counts decreased. The lactococci counts of the samples with banana added (except for the control) were higher than the others. In the samples with banana and honey, a higher increase in yeast count was observed during storage compared to plain kefir (control sample). It can be said that the use of almond milk reduces the general acceptability of kefir. Almond milk can be successfully used in kefir production as a substitute for cow’s milk, if sweeteners, fruit and thickeners are used.

In this study, the reproductive and growth performance of Akkaraman sheep between 2017-2021 were evaluated within the scope of the National Sheep and Goat Breeding Project in the Hand of the Public, which is being carried out in the province of Nigde. In the research, data obtained from 30923 animals in 22 farms in 7 villages in the central district of Nigde province were used. In the study, the effect of year, dam’s age, gender and birth type on birth weight (BW), live weight on day 60 (LW1), live weight on day 120 (LW2), daily live weight gain (DLWG) on day 120 were investigated. The effects of year, dam’s age, gender and birth type on BW, LW1, LW2, DLWG were found to be statistically significant. While the effects of year, dam’s age and gender were found to be statistically effective on SR, the effect of birth type was found to be insignificant. In the study, fertility, fecundity and litter size in Akkaraman lambs were determined as 0.92, 1.03 and 1.13, respectively. As a result, remarkable progress has been achieved in Akkaraman lambs in terms of performance characteristics (LW1, LW2 and DLWG) between 2017 and 2021.

This experiment investigates the effect of flaxseed meal, rapeseed meal and vitamin E supplementation, when used together, on the production parameters of fatty acid composition and eggs quality characteristics in Tetra SL laying hens (38 to 46 weeks of age). For this, 120 hens were allocated one of three treatments, with 40 hens in each group. The hens were fed either a control diet (C), a control diet including 2.5 % flaxseed meal and 2.5% rapeseed meal (E1) or 2.5% flaxseed meal and 2.5% rapeseed meal with 73 mg/ kg feed of vitamin E as an antioxidant supplement (E2) for 8 weeks. Hens consuming the E1 diet had greater egg production and egg mass than those from group C. The feed conversion ratio in both the E1 and E2 groups was lower (P < 0.05) than in the C diet group. E2 had considerably higher egg weight, albumen pH, yolk pH and Haugh unit than E1 and C (P0.05), as a response to the vitamin E antioxidant effect. The most α-linolenic fatty acid content (1.07 g FAME) was found in eggs produced by chickens fed the E2 diet, (1.07 g FAME), followed by E1 (0.91 g FAME), with both being significantly higher than C eggs (0.23g FAME). Furthermore, all n-6 studied fatty acids concentrations were significantly lower (P < 0.05) in E1 and E2, while all n-3 fatty acids concentrations were significantly greater (P > 0.05) in E1 and E2. When comparing the n-6/n-3 ratio of fatty acids from experimental treatments (6.44 and 6.74) with C treatment (18.19), a significant difference was observed (almost 65% lower).

This study was carried out in Isparta University of Applied Sciences, Faculty of Agriculture, Agricultural Research, and Application Farm in 2021 to determine the effect of different irrigation water levels on tuber yield and quality parameters of the Agria potato variety. Drip irrigation method was used in the study and five different irrigation water levels (S1: 120% of the seven-day ETo, S2: 90% of the seven-day ETo, S3: 60% of the seven-day ETo, S4: 30% of the seven-day ETo, S5: No irrigation except germination and emergence) were determined based on the reference evapotranspiration (ETo). Irrigation water (IW) amounts varied between 85.66-639.26 mm and evapotranspiration varied between 296.54-825.15 mm. Different amounts of IW significantly affected the vegetative growth, yield and quality parameters of potato. As irrigation water decreased, total tuber yield and marketable yield declined. Total tuber yield and marketable yield were 46.11 t/ha and 40.59 t/ha, respectively, in S1 treatment where the maximum amount of IW was applied, while they were 12.96 t/ha and 6.37 t/ha, respectively, in S5 treatment where no irrigation was applied. Logarithmic relationships were determined between evapotranspiration and total yield and between the amount of IW and total yield. Water use efficiency was determined between 43.69-55.88 kg/(ha×mm) and irrigation water use efficiency between 32.34-51.86 kg/(ha×mm) and yield response factor (ky) was calculated as 1.19.

The fly ash generated from a Romanian power plant was used as a starting material in this study. The aim of the study was to obtain a low cost material based on the treatment of fly ash with Fe3O4 for utilization as an adsorbent for cadmium ion removal. The adsorbent that was synthesized was characterized using different techniques. The adsorption process was investigated by the batch technique at room temperature. The quantity of cadmium ion adsorbed was measured spectrophotometrically. The experimental data showed that the material can remove cadmium ions at all three working concentrations. The adsorption capacity increased with an increase in concentration, respectively contact time. The results were analyzed through two kinetic models: pseudo first order and pseudo second order. The kinetics results of cadmium adsorption onto a magnetic material are in good agreement with a pseudo second order model, with a maximum adsorption capacity of 4.03 mg/g, 6.73 mg/g, and 9.65 mg/g. Additionally, the pseudo second order model was linearized into its four types. The results indicated that the material obtained show the ability to remove cadmium ions from an aqueous solution.

Vegetables grown in mining areas can accumulate significant amounts of heavy metals (HMs), which can cause serious developmental disorders and have long-term negative effects on public health. In the present study, the HMs contamination level in vegetables grown around the Riruwai mining area in Kano State, Nigeria, was investigated. Fifteen (15) vegetable samples were collected, including lettuce (Lacuta sativa L.), tomato (Solanum lycopersicum L.), and bean (Phaseolus vulgaris L.), as well as their corresponding soils. The levels of As, Cd, Cr, Hg, Mn, Ni, Pb, and Zn in all the samples were determined using Microwave Plasma Atomic Emission Spectrometry, and the measured concentrations were used to calculate the bioaccumulation factor (BAF). The results of the study revealed that HMs concentrations in the investigated vegetables were found to be significantly high, with the majority of levels exceeding the WHO/FAO (2007) recommended limit, and the concentration of HMs in the soil decreased in the order of Zn > Mn > Cr > Pb > As > Ni > Cd > Hg, with As, Pb, and Zn exceeding the WHO/FAO (2001) recommended limit. Pollution levels were found to significantly differ between HMs and vegetable types. BAF results revealed that cadmium is an accumulator of all the studied vegetables (BAFs > 1), while mercury was found to be an accumulator of L. sativa. Higher concentrations of these metals in vegetables and soil, particularly arsenic, cadmium, lead, and zinc, necessitate immediate scientific attention and further research to determine the optimum concentration required for human health. Planting of vegetables for human and animal consumption should be stopped until this is accomplished.

The aim of this study is to determine the effects of adding different levels of red pepper oil to quail diets on performance, slaughtering characteristics, and some serum parameters. For this purpose, a total of 300-day-old and mixed-sex quail chicks were randomly assigned to 5 treatment groups with 6 replications of 12 chicks each. Experimental animals were fed for 35 days with 5 different diets prepared by adding 0, 300, 600, 900 or 1200 mg/kg red pepper oil. During the experiment, quails were given ad-libitum feed and water. According to the results of the experiment, the effect of adding red pepper oil to the diet on the performance, carcass traits and visceral weights of the quails was statistically insignificant. Triglyceride and TAS concentrations of serum were significantly affected by the addition of red pepper oil to the diet. The highest triglyceride and TAS levels in the group with 300 mg/kg red pepper oil added; however, the lowest triglyceride and TAS levels were obtained in the groups supplemented with 600 mg/kg and 1200 mg/kg red pepper oil, respectively. According to this study findings, it can be said that the addition of red pepper oil to the diet in growing quails has a positive effect on serum triglyceride and TAS values when used between 300 mg/kg and 600 mg/kg in the diet, without adverse effects on performance and carcass characteristics.

Se compara el crecimiento de plántulas de la orquídeas epifita Tolumnia variegata en medios de agar con y sin hongos micorrízicos. Los métodos de germinación simbiótica produjeron embriones de T. variegata más desarrollados que los métodos de germinación asimbiótica y las diferencias fueron estadísticamente significativas. Las semillas en los controles en medio de celulosa sin hongos micorrízicos no germinaron. Las semillas de Epidendrum ramosum, Lepanthes rupestris y Psychilis monensis no mostraron diferencias significativas en germinación entre métodos simbiótica y asimbiótica utilizando hongos aislados de raíces de T. variegata, incluso algunos aislados del grupo Rhizoctonia parasitaron las semillas. Los resultados sugieren que las semillas de orquídeas epifitas y sus hongos micorrízicos son más específicos de lo que anteriormente se había creído y por tanto es necesario utilizar los hongos específicos para cada especie de orquídea. Además, se sugiere que los cultivadores de orquídeas podrían obtener mejores resultados en la propagación de orquídeas epifitas si utilizan metodologías de germinación simbiótica apropiados.

Symbiotic germination produced more-developed embryos than asymbiotic germination. Differences were highly significant, although some isolates of Rhizoctonia-like fungi were parasitic on seeds. Control seeds in a cellulose medium without Rhizoctonia-like fungi did not germinate. Seeds of Epidendrum ramosum, Lepanthes rupestris and Psychilis monensis showed no significant differences between asymbiotic and symbiotic germination using mycorrhizal fungi isolated from T. variegata roots, suggesting high mycorrhizal specificity. Our data suggest that the relationship between epiphytic orchids and the mycorrhizal fungi is more specific than previously thought. The use of the right fungal strain may enhance germination performance. Orchid growers may achieve better results in the propagation of some epiphytic orchids using symbiotic germination.

Black soldier fly larvae (BSFL; Hermetia illucens L.) is a proven high-cost protein source replacer and could be grown in a range of bio-degradable waste materials where hardly incorporated into broiler diets locally. The present study was aimed to assess the nutritional composition of BSFL, and apparent metabolizable energy (AME) value of BSFL meal provided to broiler chickens. BSFL full-fat meal produced from kitchen waste as a substrate were examined for their proximate composition, minerals and fatty acid profile. Eighty, 21-d old unsexed Cobb-500 broiler chickens (BW±SD: 665.8 ±14.3 g) were assigned randomly into 16 battery cages (04 replicates, five birds/replicate). A maize-soybean meal-based diet was used as the basal diet which was partially substituted by pre-analyzed BSFL meal at the rates of 5%, 10%, and 15% to produce three test diets. Birds were fed in a completely randomized design for 7-d with a 4-d adaptation period. Excreta were collected for three days from day 25 to 28. The results envisaged that the crude protein (CP) and ether extract (EE) contents of the kitchen waste were 12.3%, and 10.5%, respectively. BSFL meal when analyzed had 34.4% CP and 47.3%, EE. The fatty acid (FA) profile of the kitchen waste was more or less similar to that of BSFL‘s meal. The estimated AME of the BSFL full-fat meal fed for broilers was estimated to be 15.7 MJ/kg. The BSFL full-fat meal can be utilized sustainably in feed formulation and has a high potential to replace costlier feed ingredients.

2023
Hatice Tekoğul
Türkiye; birbirinden farklı ekolojik özelliklere sahip olup akarsu ve göller bakımından zengin bir ülkedir. Bazı akarsularımız da yer altına sızarak veya sıcaklığın etkisiyle buharlaşarak kaybolur. En büyük gölümüz Doğu Anadolu'da yer alan sodalı Van Gölüdür. 2021 yılında Türkiye’de su ürünleri üretim miktarı yaklaşık 800 bin ton olup bu miktarın %59’u yetiştiricilik yolu ile elde edilirken %41’i avcılık yolu ile elde edilmektedir. Avcılığın %10’u iç sulardan karşılanırken, yetiştiriciliğin yaklaşık %29’unu oluşturmaktadır. Yapılan bu çalışmada, Van ilinin son 22 yıllık (2000-2021) su ürünleri üretim miktarının elde edilmesi hedeflenmektedir. Bu amaçla Türkiye istatistik Kurumu (TUİK, 2000-2021) veriler yardımı altında Van ilinde yapılan avcılık ve yetiştiricilik yoluyla elde edilen türlerin trend analizi ile 2050 yılına kadar üretim miktarının tahmin edilmesi amaçlanmıştır. Van ilinin 2000-2021 yılları arasında avcılık yoluyla en çok avlanan iç su balıkları türleri sırasıyla; İnci Kefali (Chalcalburnus tarichi), Sazan (Cyprinus carpio), Siraz (Capoeta Pestai), Alabalık (Salmo spp.). Yetiştiriciliği yapılan tür ise sadece Alabalık’tır. Sonuç olarak, Van ilinde avcılık yoluyla elde edilen tatlı su balıkları üretiminde yıllara bağlı olarak genel bir azalmanın varlığı gözlenmektedir. Hatta bu şartlar devam ederse Siraz balığının 2022 yılında üretim verilerinde, Sazan balığının ise 2024 yılında üretiminin sona ericeği tahmin edilmiştir. Bunun yanında yetiştiricilik yoluyla üretilen tek tür olan Alabalık üretiminin artacağı bulunmuştur.
