Serkan Uğurlu | Berrin Okuyucu | Mehmet Levent Özdüven
This study was carried out to determine the effects of lactic acid bacteria (LAB) inoculants and lactic acid bacteria+enzymes (LAB+E) inoculant on the fermentation, aerobic stability, and feed value of rye silages. Whole crop rye was harvested at dough stage. Biosil (Wuthenow, Germany), Silaprilis Pro (Timac Agro, USA) and Sil-All (Allteck, UK) were used as lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants. Inoculants were applied to silages at 6.00 log10 cfu/g levels. After the treatment, alfalfa was ensiled in 1.0-L special polyethylene vacuum bags. The bags were stored at 20±2°C under the laboratory conditions. Three bags from each group were sampled for chemical and microbiological analyses 2, 4, 8 and 75th days after ensiling. At the end of the ensiling period, all silages were subjected to an aerobic stability test for 5 days. In addition, in vitro dry matter, and organic matter digestibility of experiment silages were determined. The results showed that lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants increased characteristics of fermentation and aerobic stability of rye silages. Lactic acid bacteria+enzyme mixture inoculants decreased neutral detergent fiber, acid detergent fiber and celluloses content in the silages. Lactic acid bacteria+enzyme mixture inoculants increased in vitro dry matter digestibility, organic matter digestibility and metaboze energy of rye silages. Therefore, lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants might improve the fermentation properties and feed values of rye silages harvested at dough stage.

Cihan Çakmakçı
The objective of this study was to compare predictive performances of four machine learning (ML) models: Support Vector Machines with Radial Basis Function Kernel (SVMR), Classification and Regression Trees (CART), Random Forest (RF) and Model Average Neural Networks (MANN) to predict live weight from morphological measurements of Norduz sheep (n=93). Seven morphological measurements; chest girth (CG), chest width (CW), chest depth (CD), height at withers (HW), body length (BL), heigth at rump (HR) and rump width (RW) were used to predict live weigth (LW) of Norduz sheep. All morphological measurements were positively correlated to LW. Live weight had the highest correlation with CG and the lowest correlation with HR. Initially, highly correlated predictors were removed from the data set. The remaining predictors were then subjected to variable selection procedures using the Boruta algorithm. The results of Boruta confirmed the importance of the four predictors HW, BL, CW, and CD. However, HR confirmed to be unimportant was excluded from the dataset. The ML models were trained on selected predictors. The results showed that the prediction performance validated using the test dataset indicated that RF had the lowest values of Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and Mean Absolute Percent Error (MAPE). The permutation-based variable importance scores indicate that CW and CD were the most important variables in predicting LW. The actual LW had the highest significant positive correlations with the values predicted by SVMR and RF, and followed by ANN and CART models respectively. There were no differences between the means of actual and predicted LWs by machine learning models. The fact that the models generalized well on the testing data sets indicates that machine learning algorithms have valid predictive patterns and are effective methods in LW weight of Norduz sheep. Considering runtime of the models, although the CART model had the lowest computational cost, it had the worst performance. The MANN algorithm, on the other hand, required a longer runtime to process the same dataset.

2022
Yavuz Topcu
In recent years, climate change and Covid-19 pandemic have dramatically caused some attitude variation on consumers’ food consumption preferences. By measuring the impacts on their behaviors of these changes, using as a policy tool is of a great importance. This research was conducted to analyze the total effect of sensory quality and mediating effect with natural risk factor on veal consumption hedonism of consumers in Erzurum province under climate change and Covid-19 epidemic. The main data of the study was consisted of primary data obtained from 385 household in 2021. The data were used in basic effect model to measure the sensory quality effect on consumption hedonism, and then in mediating effect model to determine indirect effects of risk factor playing linking role. The results of the study indicated that sensory quality being of high total effect on consumers’ veal consumption hedonism in basic effect model explained 64% of total variance. On the other hand, it was determined that sensory quality’s direct effect on consumption hedonism in mediating effect model with risk factor was lower, but the risk factor’s indirect effect was meaningful, and had a higher explanation rate than that in basic effect model. In order to be able to increase consumption hedonism, human diets should include consumption based on alternative meat and protein sources of vegetable origin instead of veal consumption. Hygiene decisions minimizing Covid-19 infection risk, moreover, at production and marketing stages of alternative meats should be taken and implemented.

Gökhan Gurur Gökmen | Duygu Kışla
Nanotechnology has a wide study field including organic and/or inorganic particles smaller than 100 nanometers and all kinds of technological studies developed using these particles. In the production of nanoparticles, top-down approaches in which macro-sized materials were reduced to nano-sizes and bottom-up approaches in which atoms / molecules were increased to nano-sizes by different chemical reactions, are used. Currently, nanoparticles produced by top-down approaches might be used in many industries such as food industry, water treatment systems, cosmetics, and medicine. Microorganisms that tend to move, adhere, and colonize a solid surface, cause the formation of microbial biofilm on these surfaces. Microbial biofilms show high resistance to traditional antimicrobial applications in industrial environments especially where food is processed, water piping systems, biological tissues and medical implants. Therefore, the requirement has emerged to make not only the surfaces in direct contact with people, but also the surfaces in contact with food, to be resistant to microorganisms by different antimicrobial coating techniques. In this review, it is aimed to give information about the production methods of nanomaterials, different antimicrobial surface-coating techniques, the mechanism of antimicrobial nanoparticles on microorganisms and potential applications of antimicrobial surfaces.

2022
Gizem Aksu
Drought is an important environmental stress that limits crop production in the world. Its importance has increased with global warming and it has become one of the most important factors limiting plant production. Soybean is the more source of obtaining and cheaper protein per unit area. Soybean has a widespread use in livestock because it contains valuable amino acids as well as high protein quality. The aim of this research is to diminish negative effect of drought stress in the forage soybean with indole acetic acid application. The experiment was carried out in the growth chamber according to a randomized block design with 4 doses (0-5-10-20 μM IAA) of indole acetic acid, 2 drought levels (0 and -0.5 MPa PEG-6000) and 3 replicate. Leaf length and width, leaf proportional water content, cell membrane damage and malondialdehyde (MDA) content of the plants were determined. The data were evaluated by analysis of variance using a statistical package program. According to the analysis of variance, all parameters were found to be statistically significant in drought x indole acetic acid interaction. Indole acetic acid applied to the forage soybean plant alleviated the damage caused by drought. For this reason, it is thought that it may be important to ensure less damage to plants grown under stress.

Difficulties in adventitious root formation in blackberry (Rubus fructicosus L.) cuttings create a disadvantage for producers. The aim of this study is to investigate the effect of different growth regulator applications on the rooting ability of blackberry hardwood cuttings in order to avoid this problem. The experiment was carried out in the polycarbonate greenhouse of Tokat Gaziosmanpaşa University Agricultural Research and Application Center In the experiment, in addition to the control (pure water) group, Indole-3-Butyric Acid (3000 ppm IBA) and different doses of paclobultrazole (500 ppm PBZ1, 1000 ppm PBZ2, 1500 ppm PBZ3) were applied to hardwood cuttings separately and in combination. After the application, the cuttings were planted in perlite medium and left to root for 90 days. At the end of this period, in the cuttings removed; rooting rate, callus formation rate, root number, root length and root diameter parameters were examined. As a result of the study, the highest rooting rate was obtained from the IBA applied cuttings (%42.22), followed by the PBZ1 applied cuttings closest (%33.33). In addition, it was determined that PBZ applications had positive effects on root diameter compared to the control group. The results obtained are important in terms of contributing to the literature and benefiting the enterprises

In this study, it was aimed to reveal some viruses that are a problem in tomato production areas in the Ereğli district of Konya, where tomato production is common. For this reason, in the 2019 production season, leaf samples were taken from 160 tomato plants showing symptoms similar to virus disease symptoms such as mosaic, deformations, yellowing, blight on the leaves and stunted plants. Possible infections of Cucumber mosaic virus (CMV), Tomato spotted-wilt virus (TSWV) and Tomato mosaic virus (ToMV) on these leaves were tested by serological-based DAS-ELISA (Double Antibody Sandwich- Enzyme Linked Immuno Sorbent Assay) method. According to DAS-ELISA results, it was determined that 66.25% of the samples were infected with at least one of these three viruses. In addition, TSWV was detected as the most common virus with a 48.75% relative infection rate in the samples, followed by ToMV (28.75%) and CMV (26.25%). Mixed infections of the viruses were also detected in the leaf samples tested. CMV + TSWV double infection was detected in 22 samples, ToMV + TSWV double infection was detected in 14 samples, and CMV + ToMV + TSWV triple infection was detected in 12 plant samples.

Serhat Hepçin | Ali Gücükoğlu
This study aimed to investigate the presence of Aflatoxin M1 (AFM1) in raw buffalo milk and buffalo milk products such as cheese, yogurt, cream, and ice cream by ELISA technique. In the study, 175 samples were investigated, and it was determined that 146 (83.43%) of the samples had AFM1 concentrations below the LOD (limit of detection) value. In 29 samples (16.57%), the AFM1 concentration exceeded the LOD value, and in 7 (4%) of these, the AFM1 concentration was above the legal limits (50 ng/L). While AFM1 was not detected in raw buffalo milk samples, the presence of AFM1 in cheese, yogurt, cream, and ice cream samples was found to be 2.85%, 2.85%, 62.85%, and 14.3%, respectively. 2.85% of cheese samples and 17.1% of cream samples were found contaminated with AFM1 above the allowed legal limits (50 ng/L). As a result, it was determined that the potential for exposure to AFM1 by consuming buffalo cream was higher than the consumption of buffalo milk and other buffalo milk products. However, the detection of AFM1 above legal limits in buffalo milk products poses a serious risk to public health. Therefore, it is extremely necessary for public health to develop effective monitoring programs to control aflatoxin contamination in milk and new strategies to maintain inspections.
