Camel Milk Production System in Türkiye 全文
2022
Atakan Koç
Camels are known as "ship of the desert" and "beast of burden" and resistant to harsh climatic conditions. Their function has changed in the modern world and they have become a food source like other farm animal species. In the last 60 years, the number of camels, their meat and milk production in the world have increased 3.0, 4.95 and 5.0 times, respectively. In Türkiye, both Bactrian and dromedary camels are reared since F1 hybrid ♂ Tülü (Bactrian ♂ x dromedary ♀) perform better in camel wrestling, which is a unique culture of Anatolia. There are also a few farms aiming to produce camel milk and rearing young camels intensively in Türkiye. However, many practices such as calf rearing, insemination of cows, milking stimulation, milk preservation, milk quality control, milk collection and marketing and milk processing into the products are not as modern as in dairy cattle production. Although dairy camel farms in Türkiye have a higher milk production potential, since high milk prices lead to low demand for camel milk and there is only one camel milk processing facility to turn camel milk into products, farms produce far below their capacity. Processing camel milk into the products such as cheese, whey, yoghurt, pasteurized milk, kefir and ayran is still in its infancy. In conclusion, although the basis of camel rearing in Türkiye today is based on wrestling camel breeding, understanding of the benefits of camel milk on human health and the increase in demand for camel milk products suggest that this situation will change in favour of dairy camel breeding in the near future.

Emine Açar | Yıldız Aka Kaçar
The Myrtle plant (Myrtus communis L.) is a plant species of the Myrtaceae family and a member of the maquis community, which naturally spreads in Mediterranean regions. Being resistant to arid conditions, the ecological distribution areas of the myrtle plant have been allowed to expand. The myrtle plant has been used of medicinal and aromatic plants, having interesting and beautiful flowers, and rich nutrient content of the fruit in terms of valuable phytochemicals, in particular, the nutritional content of its fruits and valuable metabolites have allowed the myrtle plant to be among the healthier foods. Antioxidant activity, which neutralizes reactive oxygen species (ROS), which causes many medical problems, is one of the most important features of the myrtle plant. Investigation of the biosynthesis of anthocyanin, which leads to antioxidant activity, and determination of the biosynthesis in different tissues and genotypes is important, especially in the development of production activities. Furthermore, this study aimed to investigate the anthocyanin biosynthesis in different genotypes with white and black fruits and various tissues of genotypes. For this purpose, the expression levels of CHS, CHI, F3H and PAL genes, which are involved in the anthocyanin biosynthesis pathway, were determined by qRT-PCR. In the study, it was determined that there was an increase in the level of genes related to the biosynthesis of anthocyanin in the leaf and fruit tissues of the genotype with white fruits. It was determined that the expression level of genes related to the biosynthesis of anthocyanin was observed to be higher in the leaf and fruit tissues of the genotype with black fruits, and the highest gene expression level was found in black fruits. It was observed that anthocyanin biosynthesis was synthesized in different tissues of the plant, and anthocyanin biosynthesis was higher in fruits compared to leaves.

In this study conducted to investigate the effect of breeding flock age on the fattening performance and carcass characteristics of broilers, Ross-308 chicks obtained from the eggs of breeding in three different age groups; young (30 weeks old), middle (47 weeks old), and old (59 weeks old) were used. For this purpose, three different treatment groups and three replications in each treatment group were formed depending on the breeder age in the experiment. In the study, 30 chicks in each replication, 90 chicks in each treatment group and 270 chicks in total were used. At the initial and the end of the experiment, the differences observed between the treatment groups in terms of live weight were found to be significant. It was determined that chick live weights per trial increased with increasing flock age (P0.05). As a result, although chicks obtained from old flocks had higher live weight at the beginning of the experiment, the effect of flock age on fattening performance and carcass parameters was eliminated at the end of the experiment and showed similar values with the chicks obtained from medium and young flocks.

Gülsüm Atasoy | Pınar Şanlıbaba | Rahmi Ertan Anlı
In the present study, we aimed to isolate and biochemically identify tyramine-producing lactic acid bacteria (LAB) from black and green fermented olive samples produced by traditional methods and obtained from different provinces of Turkey. A total of 36 LABs, including Enterococcus spp. (2 isolates), Lactobacillus spp. (16 isolates), and Lactococcus spp. (18 isolates) were isolated from the fermented olive samples. Among them, 27 isolates could decarboxylate tyrosine amino acid; however, the decarboxylase enzyme activity of the remaining 9 isolates was negative. The ability of LAB isolates with positive enzyme activity to produce tyramine was evaluated using high-performance liquid chromatography (HPLC), and 6 isolates were found to be significant tyramine producers in vitro, producing tyramine at concentrations ranging from 107.251 to 207.618 mg L–1.

African eggplants are highly valued constituents of the Nigerian food. However, their nutritional potentials have not been fully tapped due to inadequate information on their nutritional and anti-nutritional qualities. This present study investigated the proximate, minerals, anti-nutrient contents as well as the estimation of mineral ratios and Mineral Safety Index of four selected edible solanum species namely, Solanum anguivi, S. gilo, S. menalogena and S. aethiopicum. The proximate contents (%) ranged from 4.19-5.46 (moisture content), 1.71-2.49 (crude fat), 4.57-5.45 (crude ash), 3.76-4.93 (crude protein), 5.20-6.30 (crude fiber) and 77.14-78.58 (carbohydrate). The solanum species were good sources of energy with total metabolizable energy of 1.458MJ-1.484MJ. The four solanum species contained high K, Ca, Mg, low Fe, Mn, Zn and Cu, while amount of Cd, Ni and Pb were very low. The mineral ratios of K/Na, Ca/Mg, Ca/K, Zn/Cu and [K/(Ca+Mg)] were below the minimum good ratios levels of 1.0, 4.17, 4.0, 8.0 and 2.2 respectively which are good for man. The anti-nutrient contents revealed low phytate, oxalate and cyanide levels. The calculated Phytate/Zn, Phytate/Ca and Oxalate/Ca were lower than the threshold levels and would support absorption and bioavailability of Zn and Ca in the samples while that of Phytate/Fe was above the critical value and this indicates unavailability of iron in these eggplant fruits. The mineral differences observed showed that S. menalogena and S. aethiopicum had greater minerals while the Mineral Safety Index results revealed that the body could not be overloaded with any of the minerals investigated. The eggplants are rich in fiber, ash, carbohydrate and minerals with moderate protein. The low level of the anti-nutrient is good and poses no deleterious effect when consumed. The eggplants have nutritional health benefits; hence, their consumption should be encouraged to address food insecurity in Nigeria

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.

Oxidative stress resulted from free radicals and reactive oxygen species (ROS) are associated with many diseases. Phytotherapy has known a great evolution all the world and some medicinal plants are important remedies of some diseases. Myrtle (Mrytus communis L.) is a plant of Myrtaceae family which is common in the Mediterranean region, with flowering, always green leaves and fruit. This study aims to investigate in vitro antioxidant capacity of Myrtus communis berries methanol extract and its three fractions using five assays: ABTS scavenging radicals, metal chelating, hydrogen peroxide and inhibition of lipid peroxidation assays. EAE extract possessed the highest antioxidant activity in ABTS (EAE (IC50=2.5 µg/ml ) and lipid peroxidation models (90.17%). Whereas, AqE is the most active extract in metal chelating activity (IC50=0.73±0.03 mg/ml) and H2O2 assay. These results support the traditional use of this plant in healthcare and it could be a new source of antioxidant natural drugs.

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.
