2022
Mehmet Burakalp Yusuflu | Sakine Ülküm Çizmeci
The present study, it was aimed to determine the effect of antioxidants added to culture media on blastocyst development rates in in vitro embryo production. The material of the study consisted of oocytes collected from the ovaries taken from the slaughterhouse. Cumulus oocyte complexes (COC) were collected and classified under a stereomicroscope. Oocytes included in the study were subjected to maturation and fertilization stages. Probable zygotes were transferred to the culture (IVC) containing antioxidants (L-ergothionine 100 μM (n: 163), Vitamin E 100 μM (n: 151) Cysteamine 50 μM (n: 154) and were cultured in a tri gas incubator (Hera Cell- 6% O2%, 6%CO2, 88%N). Blastocyst rates and embryo quality were determined on the 6th and 7th days in culture medium. Differences in IVMFC stages were evaluated by chi-square test. 966 oocytes were collected from 162 ovaries collected from the slaughterhouse. It was determined that the number of oocytes per ovary was 5,96, and the number of A and B quality oocytes was 4.26. It was determined that 655 (94.93%) of a total of 690 oocytes undergoing in vitro maturation were mature. The cleavage rates of the groups were 83.44%; 80.79%; 79.87%, and 83.96%, respectively. 140 (21.37%) blastocysts were obtained from 655 oocytes taken into the culture stage and the blastocyst rates in the groups were 33.13%; 8.61%; 7.79%, and 32.62%, respectively. As a result of the study, it was determined that the rates of blastocysts in the L-ergothioneine added the group was similar to the control group, but the blastocyst rates decreased significantly in the cysteamine and Vitamin E added groups. It was thought that this decrease might have been affected by the dose of antioxidants or the adequacy of oocyte development

Zehra Mezreli
In recent years the number of phytoplasma diseases that negatively affect yield and quality of many plants has been increasing around the world. As is known grafting, plant propagation materials (seed, bulb, tuber), parasitic plants and insect vectors play active role in the spread of phytoplasmas causing these diseases. These organasim which get through plate in the sieve tube element and systemically colonize the plant, it invade and multiply salivary glands, midgut, heomocel, brain and fat tissue after sucking up insect body with stylet. Subsequently they continue the cycle by moving to a new plant with a diseased insect feeding on a healthy plant. Although the existence of functional genomics in this cycle is known, there is little information about transmission of phytoplasma from vector to host plant or from host plant to vector, the mechanism of disease caused by phytoplasma in the plant and genomics involved in different reactions in the host plant against phytoplasmal infection.

In this study, we aimed to determine the therapeutic value of local Yığılca honeys by examining their physicochemical characteristics, phenolic content, radical scavenging activity, and antimicrobial properties by underlining some overlooked parameters. Honey samples ware divided into two main groups as CH and FH based on melissopalynologycal analysis. Antimicrobial activity of collected honey samples were investigated on important hospital-acquired infections bacteria strains; MRSA (Methicillin-resistant Staphylococcus aureus), MSSA (Methicillin-sensitive Staphylococcus aureus), Escherichia coli, and Acinetobacter baumannii. Although CH’s antimicrobial activities were found slightly higher than the FH’s, there isn’t statistically significant differences between two type honeys. However, the antioxidant activity of CH was found significantly higher than FH. Surprisingly, a higher amount of isomaltose was determined in addition to the total phenolic content in CH compared to FH. There has been found positive correlation between isomaltose amount and zone diameters for MRSA and A. baumannii. We would like to draw attention to isomaltose for its health benefit structure since these parameters may be influence honey’s therapeutic value. We recommend that isomaltose and invertase enzyme should be included in to the honey codex standards suitably depending on the monofloral and multifloral honey’s specific structure, to sensitively standardize and control their quality and therapeutic value. Our data revealed a positive correlation between antioxidant and antimicrobial activity and total phenolic content and higher isomaltose amount.

We, here, aimed to determine the presence of Anguillicola crassus, a swim bladder parasite, in 89 (male: 45, female: 44) dead European eel specimens obtained seasonally between 2020-2021 from a regional fisherman, who has fished with fyke net in the locality Tuzla of Izmir Bay, Eastern Aegean Sea. Out of 21 male European eels caught in winter, only one specimen (TL: 48.5 cm and TW: 247.12 g) had 23 swim bladder parasites (adult nematodes: 15, larvae: 8) and similarly, only one parasite was found in one specimen (TL: 37.5 cm and TW: 88.47 g) of 8 eels caught in spring. No parasite was found in the female eels. At the examinations, it was determined that all adult Anguillicola crassus specimens were females and the minimum-maximum and average length values in adult and larval parasites were, respectively, 1.5-2.5 cm (1.99 ± 0.31) and 0.7-1.3 cm (1.025 ± 2.40). Consequently, the species A. crassus, a swim bladder parasite, was found in European eels from the locality Çamalti Tuzla in two seasons (winter and spring) and this parasitic nematode were only in male eels. This study is a first and remarkable one having evidential value, which shows the presence of the species A. crassus among the eel population in the locality Çamalti Tuzla of Izmir Bay. Besides, it is a population that should be monitored due to the status of Anguilla anguilla on the IUCN red list.

Fatih Araz | Başaran Karademir | İbrahim Hakkı Kadirhanoğulları
Organic agricultural products are food products that are inspected and certified at all stages of production until they are offered for consumption by institutions that are authorized by the state. Beekeeping products made for human food are also subject to the same certification process. With this research, it was aimed to reveal the organic beekeeping and organic honey understanding of the people of Iğdır region. With the survey, the information of the local consumers about organic honey, how they got this information, their status and reasons for organic honey consumption, as well as the certification processes were collected. The obtained data were analyzed with numerical, proportional, and decision tree methods. The genders of the survey participants were 66% male, 34% female. It was also determined that 70.5% of the participants were under the age of 40, had a bachelor's degree or higher education level in the proportion of 43%, and 63% had a minimum wage or lower-income level. For the questions asked about the research topic, it was reported that participants know and eat organic honey in the proportion of 93%, buy organic honey in the proportion of 77.5%, having information about the organic honey certificate in the proportion of 67% and certification stages in the proportion of 43%. Despite these high rates, the same participants gave contradictory answers to some other questions, such as; for the question of “What is organic honey?” the answer of "Certified honey" in the proportion of only 11.5% and for the question of “How did you know that the organic honey you bought was organic honey?” the answer of " I saw its certificate” in the proportion of only 18.1%. This contradiction was noted. With this research, it was determined that the local people did not have enough information about organic beekeeping and honey understanding. In order to fill this gap, it can be suggested that healthy nutrition lessons be included in the education curricula starting from primary school, and usage of TV, radio, and internet broadcasting for this purpose. The fact that the participants' education level is high and their age is young may provide an advantage in order to get results from the training to be given on the subject.

Sanaa Khaled | Hiba Al Wardany | Ward Al Bast
Labneh is one of the most consumed dairy products in the Lebanese community, on breakfast, as a snack or on dinner, plane or mixed with herbs. Its various health benefits plus its acceptability among people makes it an important part of the Lebanese diet. In both its synthetic and homemade forms, several additives are usually incorporated to enhance its flavor and offer a variety of tastes. The problem with Labneh is its short shelf life, as well as its sensitive sensory profile. That is why most industries mix chemical additives with Labneh to prolong its shelf life and conserve its taste. The aim of this research is to preserve Labneh naturally by adding Moringa Oleifera dried leaves to extend its shelf life and inhibit rapid spoilage. Working on a natural preservation of Labneh instead of chemical preservation will be assessed by the survey’s results and prepare for studying the overall acceptability of the product by making a sensory analysis. The results of the questionnaire showed that the Lebanese community which is not totally aware of Moringa Oleifera benefits and availability, is willing to try fortified Labneh with Moringa as a new product with extended shelf life and more health benefits. The results of the sensory analysis showed that the sensory attributes of the samples with Moringa after 21 days of storage, where not significantly different than normal plane Labneh, which indicate that adding Moringa did not affect the sensory attributes of Labneh giving it more acceptability to consumers.

Poultry meat quality is controlled by muscle fiber properties associated with body weight gain in the immediate pre- or post-hatch period. This study aimed to determine the effect of administration of branched-chain amino acids blend (BCAAb, 3 L-leucine:1 L-isoleucine:2 L-valine) in the pre- or post-hatch period on the growth performance and fiber characteristics of the Pectoralis major (PM) muscle in turkey poults subjected to early or delayed feeding. Newly hatched poults from eggs injected in ovo with BCAAb or received no injection were used in a 21-d study. Poults (n=192) produced without injection of BCAAb received a starter diet supplemented (BCAA) or not (C) with the BCAAb (2 g/kg) immediately or with a delay of 48 h (48BCAA and 48C) after hatching. Poults (n=36) produced with (IOBCAA) in ovo injection of BCAAb (2 mg /ml) received the diet and water immediately. The BCAA and IOBCAA poults had higher body weight than those of the C, 48C, and 48BCAA birds. The body weight of the C poults was higher than those of the 48C and 48BCAA birds. The BCAA poults had higher PM muscle weight than those of the C and 48C poults, while that of the IOBCAA poults was higher than that of the 48C poults. The IOBCAA treatment increased the protein content of the PM muscle meat, compared with the C and 48C treatments. The 48C treatment increased the type IIB fiber area and the type I and type IIA fiber percentages but decreased the type IIB fiber, compared with other treatments. The numbers of type IIB and total fibers in the IOBCAA poults were higher than those of the 48C birds. In conclusion, administering BCAAb in ovo or in a starter diet enhanced early growth performance and improved the fiber characteristics of the PM muscle in turkey poults.

Bu çalışmada, 2017 yılından 2021'e kadar beş generasyon boyunca ıslah ve seleksiyonu sürdürülen Anadolu-T etlik piliç saf hatlarının gelişme ve karkas özelliklerinin ticari hibritle karşılaştırmalı olarak ortaya koyulması amaçlanmıştır. Her generasyonda seleksiyon işleminden sonra yeterli sayıda saf hat (A1, A2, A3, B1, B2) ve ticari hibrit (Ross-308) yumurtaları kuluçka edilerek her genotipten 120 dişi-erkek civciv üretilmiştir. Etlik piliçler 6 hafta süreyle etlik piliç üretim standartlarında yetiştirilmiş ve bu süre sonunda kesim ve karkas özellikleri belirlenmiştir. Gelişme özellikleri olarak canlı ağırlık (CA), yemden yararlanma oranı (YYO) ve yaşama gücü; karkas özellikleri olarak göğüs ve but eti oranı ele alınmıştır. Beş generasyon boyunca 6 haftalık yaşta en yüksek ortalama CA ve en iyi YYO Ross-308 ticari hibritlerde (CA: 2961,2 ile 3481,2 g ve YYO: 1,43 ile 1,60 arasında) elde edilmiştir ve bunu sırasıyla baba (CA: 2633,8 ile 3180,2 g ve YYO: 1,65 ile 1,77 arasında) ve ana hatları (CA: 2307,7 ile 2698,5 g ve YYO: 1,65 ile 1,78 arasında) izlemiştir. Saf hatların yaşama gücü generasyonlara bağlı sayısal farklılıklar gösterse de ticari hibritle genel olarak benzer (%96-100) gerçekleşmiştir. Hem ana hem de baba hatların göğüs oranı ticari hibrite göre daha düşük iken, saf hatlarda but oranının daha yüksek olduğu belirlenmiştir. Saf hatların beş generasyonluk kısa bir seleksiyon geçmişine sahip olması henüz yeterli bir değerlendirmeye imkân vermemektedir. Ana ve baba hatlarında bireysel yemden yararlanma testine ek olarak baba hatlarında canlı ağırlık ve göğüs alanı özelliklerinin de seleksiyon kriteri olarak kullanılmasının canlı ağırlık ve yemden yararlanmayı iyileştirmesi beklenmektedir.
