This study investigated the effects of different plant protein sources incorporated into feed concentrates on the live weight gain and feed conversion ratio of Morkaraman lambs by days 28, 42 and 56 of fattening, and presents a cost-benefit analysis. The study animals included 24 male Morkaraman lambs with a mean age of 9 months, which were assigned to 3 study groups. The dietary plant protein sources provided to the animals were soybean meal and safflower meal in Group I, wheat gluten in Group II, and corn gluten in Group III. The total feed intake values (kg) of Group I, Group II and Group III were 40.75±1.08, 39.18±0.88, and 37.67±0.62, respectively, during the period between days 0-28 of fattening; 62.77±1.67, 60.14±0.96, and 57.54±1.28, respectively, during the period between days 0-42 of fattening; and 83.31±1.89, 77.79±1.43, and 75.97±1.67, respectively, during the period between days 0-56 of fattening (p<0.05). The live weight gain values (kg) of Group I, Group II and Group III during the period between days 0-56 of fattening were 14.82±0.84, 11.97±0.51, and 13.71±0.91, respectively (p<0.05). The feed conversion ratio was observed not to have a statistically significant effect on production yields (p>0.05). In conclusion, while the highest income from live weight gain during the period between days 0-56 of fattening was achieved with the use of soybean meal and safflower meal as dietary plant protein sources, the lowest fattening cost was achieved with the use of corn gluten.

Merve Onur | Aybuke Ceyhun Sezgin
With its culinary use dating back more than six thousand years, amaranth is known as the ancient grain and the food of the future. Recently recommended for consumption by FAO/WHO, the amaranth plant is a prominent, “forgotten,” functional food that can be used in human nutrition because of its drought-resistant cultivation, gluten-free, and protein and fiber-enriched content. This study evaluates amaranth's botanical character, functional properties, impacts on health, preparation-cooking methods, and use in local and traditional Turkish cuisines. Numerous studies have indicated the association between amaranth’s chemical composition and its anti-oxidative, anti-tumor, gluten-intolerance, and cholesterol-lowering properties, and its assistance with intestinal flora and protein digestibility. Manifold dishes can be made using amaranth seeds and flour in traditional cuisines. Raw and cooked amaranth grains are used in rice, soup, and breakfast cereal. In the food industry, it is a crucial grain alternative to various bakery products, such as bread, pasta, cookies, manti, noodles, biscuits, and crackers, made from amaranth flour. There is a need for alternative recipes to increase the use of amaranth in the kitchen. In this context, it is thought that awareness should be increased by applying it to recipes that can replace semolina and bulgur in traditional cuisines. For this purpose, this study aims to increase the consumption of the ancient grain amaranth by including it in recipes in traditional Turkish cuisine.

Food waste is a significant problem worldwide. These food wastes, often discarded without any preliminary processing, can be rich in bioactive substances. In this study, the aim was to identify the phenolic compounds in pumpkin, rosehip and pomegranate seeds, which are frequently consumed in winter. For this purpose, ultrasonically assisted methanolic extracts were prepared from seeds separated from other waste parts (such as shells, stems, and leaves). The results indicated that pomegranate seeds had the highest total phenolic content, with 45.6±3.1 mg GAE/g sample (P<0.05). Similarly, pomegranate seeds also showed the highest total antioxidant capacity in both CUPRAC (114.7±2.6 mg torolox/g sample) and DPPH (71.2±3.8 mg torolox/g sample) analyses (P<0.05). In phenolic profiling analysis using HPLC-PDA, syringic acid was the most abundant compound in pumpkin seeds, (-)-catechin in rosehip seeds, and punicalagin derivatives in pomegranate seeds.

This study investigates the effectiveness of Lactobacillus rhamnosus in the detoxification of AFM1 contamination. Experiments conducted on two groups of ice cream samples measured an average AFM1 level of 0.0308 µg/kg in the control group and 0.0258 µg/kg in the group with L. rhamnosus added. The results indicate that L. rhamnosus significantly reduced AFM1 levels (46%) and was thus effective in the detoxification of AFM1. Our statistical results were found to be significant (p<0.05). These findings highlight the potential of L. rhamnosus to reduce AFM1 contamination in ice cream products, making a significant contribution to food safety. Controlling mycotoxins in food products is critical for protecting consumer health and enhancing food safety.

Ahmet Uçar | Yasin Kahya
Although there are intensively selected lines and non-selected standard breeds in terms of production characteristics in the chickens, there is limited information on the comparing their egg shape-related traits. This study aimed to compare using the parameters of weight, width, length, shape index-L/W (Length/Width), and shape index-W/L of egg in some meat-type (Anadolu-T, Ross 308, Dam Line and Sire Line), egg-type (Atak-S, Lohmann Brown and Lohmann Selected Leghorn), and standard breeds (Sultan and Ameraucana). The data from 2476 eggs from 9 genotypes obtained from 50-55 weeks hens and classified under 3 main types were analyzed with univariate and multivariate methods. The mean egg weights of Sire Line, Ross 308, Anadolu-T, Lohmann Brown, Atak-S, Dam Line, Lohmann Selected Leghorn, Sultan and Ameraucana genotypes were 69.89f, 69.10f, 62.84e, 59.59d, 59.58d, 59.51d, 56.81c, 45.87b and 43.03a g, respectively (P<0.05). In the same order, the mean egg width was determined as 44.72f, 45.61g, 43.41de, 43.32de, 43.62e, 43.17d, 42.46c, 39.90b and 39.17a mm (P<0.05). The mean egg length was found to be 61.97g, 58.80e, 59.72f, 56.12bc, 57.58d, 56.59c, 56.00b, 51.30a and 51.47a mm (P<0.05). The egg shape index-W/L and egg shape index-L/W was calculated to be 74.78a, 76.50b, 77.55c % and 138.67c, 128.99a, 137.59c, 129.45a, 132.16b, 131.12b, 131.93b, 128.68a, 131.47b %, respectively (P<0.05). The egg weights of meat-type, egg-type, and standard breeds were 64.61c, 58.36b, and 45.42a g, respectively (P<0.01). The egg width was found to be 44.06c, 42.97b and 39.78a mm (P<0.05). The egg length was 59.05c, 56.20b, and 51.35a mm (P<0.05). We also detected significant positive correlations (P<0.01) between the egg weight and the egg width (r=0.88), and the egg length (r=0.83). In the discriminant analyses, the success of assigning eggs to their groups was relatively low (52.4%) in terms of genotypes, but high (78.1%) in the type groups. The significant changes in the egg weight and shape-related traits were determined according to chicken genotypes and types. It was observed that intensive selection in chickens, especially in egg-type genotypes, had a strong effect on egg weight and shape-related traits.

This study examined the determinants of the recall event timing of contaminated frozen poultry products in retail outlets in North-Central Nigeria. It specifically identified the potential sources of frozen poultry product hazards in retail outlets, assessed the effectiveness of existing management strategies employed by retailers in preventing frozen poultry product recall in the outlets, and examined the factors influencing the recall event timing of contaminated frozen poultry products in retail outlets in the study area. Multistage sampling was employed to sample 202 respondents, and the data collected using a well-structured questionnaire was analyzed using descriptive statistics and discrete-time survival analysis. The results showed that most of the frozen poultry product retailers in outlets in the study area were men within the age bracket of 21 and 40 years and had a monthly restocking frequency of approximately four times. The result revealed that power outage was the highest potential source of hazards associated with frozen poultry products in retail outlets in the study area. Packaging poultry products before freezing, product labelling, and fridge segmentation are effective management strategies. The result of the factors influencing the recall event timing of contaminated frozen poultry products in retail outlets showed that retailing experience (P<0.01) and cooperative membership (P>0.01) significantly influenced the recall event timing of contaminated frozen poultry products in the study area. The study recommends that the Government offer tax incentives to retailers investing in reliable backup power solutions and provide guidelines for effective communication during recall events.

Vernalizasyon bazı bitkilerin erken gelişme dönemlerindeki düşük sıcaklık ihtiyacıdır. Bu bitkilerin vejetatif dönemden generatif döneme geçiş yapabilmesi için belli bir süre düşük sıcaklıkta kalmaları gerekir. Bu çalışma bazı arpa çeşitlerinin vernalizasyon uygulamalarına tepkilerini belirlemek amacıyla yürütülmüştür. Dört kışlık, iki alternatif ve iki yazlık arpa çeşidinin kullanıldığı bu araştırma tesadüf parsellerinde faktöriyel deneme desenine göre üç tekerrürlü yürütülmüştür. Arpa çeşitlerinin çimlenmiş tohumları torf içeren küçük kaplarda 0, 4, 5 ve 6 hafta süreyle 2°C’de vernalizasyon uygulaması için bekletilmiştir. Gelişen fideler saksıya aktarılmış ve serada 22 saat ışık/2 saat karanlıkta 22°C sabit sıcaklıkta yetiştirilmiştir. Bitkilerde sapa kalkma süresi, başaklanma süresi, olgunlaşma süresi, fertil kardeş sayısı, başakta tane sayısı ve bin tane ağırlığı belirlenmiştir. Vernalizasyon uygulamalarının incelenen bütün karakterlere etkisi çeşitlere göre önemli derecede değişmiştir. Araştırmada kullanılan kışlık çeşitler Sladoran, Alba, Dicktoo ve Aydanhanım vernalizasyon ihtiyacı karşılanmadan başaklanamamışlardır. Bu çeşitlerde başaklanma süresi göz önüne alındığında dört haftalık vernalizasyon uygulamasının yeterli olduğu belirlenmiştir. Dört haftalık vernalizasyon, alternatif çeşitler Tokak 157/37’de 9 gün, Kearney’de ise 40 gün daha erken başaklanma sağlamıştır. Yazlık çeşitlerde vernalizasyon uygulaması belirgin bir değişikliğe neden olmamıştır. Vernalizasyon uygulaması süresince geçen süre de göz önüne alındığında bütün kışlık çeşitler için dört haftalık vernalizasyon süresi en uygun süre olarak görülmektedir. Alternatif çeşitler için vernalizasyon uygulaması ise genotipe bağlı değişken olduğundan dolayı, bu çeşitlerin ıslah programlarında kullanımı durumunda mutlaka vernalizasyon sürelerinin belirlenmesi gerekmektedir.

Recycling plant residues through various processes is essential for addressing waste issues in our country, because it contributes to the protection of the environment and ecosystems. Composting is one of the most important recycling methods for plant residues. Composts are not only natural, but they also enhance soil fertility and exhibit fungitoxic properties on the mycelial and spore germination of fungi. This study aimed to isolate bacterial bioagents from compost derived from various agricultural and household organic wastes, and to assess their antagonistic potential against important plant pathogens Botrytis cinerea and Sclerotinia sclerotiorum under in vitro conditions. A total of eight bacterial isolates were obtained, identified as belonging to Bacillus spp. Dual culture tests were used to evaluate the potential of these bacterial candidates to inhibit the mycelial growth of phytopathogenic fungi. In vitro trials revealed that six bacterial isolates exhibited varying degrees of antagonistic effects (23.3%- 63.3%) on the mycelial growth of B. cinerea. Among the tested bacteria, two isolates were effective against S. sclerotiorum, demonstrating antifungal activity ranging from 80% to 83.3%. The results indicate that composts provide a favorable environment for microorganisms with antagonistic potential, suggesting that these cultivation environments could play a significant role in the biological control of fungal pathogens in agriculture. In conclusion, this study contributes to the development of sustainable agricultural practices by ensuring a more efficient utilization of organic waste.

The current study aimed to evaluate Piliostigma thonningii seeds-derived essential oil (PTO) effect on hematological and reproductive parameters in rabbits. Three groups consisting of 15 animals each were randomly assigned and with an average initial body weight (BW) of 262.89 ± 22.36 g in a fully randomised experimental design. Group 1 received the control diet, while for groups 2 and 3 the basal control diet was supplemented with 2 mL PTO/kg diet and 4 mL PTO/kg diet, respectively. At the end of the experiment, blood samples were collected and the blood was analysed using the ABACUS ROSS haematology analyser. The results indicated significant differences in rabbits receiving PTO supplemented feed, namely; Packed cell volume, red blood cells, white blood cells, mean corpuscular haemoglobin concentration, neutrophil increased (P<0.05) with increasing level of PEO supplementation. Mean corpuscular volume and haemoglobin, lymphocyte, monocyte and platelet were higher (P<0.05) in T2 and T3 than in T1. Neutrophil/lymphocyte ratio was higher (P<0.05) in T3 than T1 with T2 being intermediate (P>0.05) between T1 and T3. Semen volume, concentration and motility were higher (P<0.05) in T2 and T3 than in T1. While semen abnormalities and bucks’ reaction time to does (libido) were greater (P<0.05) in T1 than in T2 and T3, Live dead ratio was higher (P<0.05) in T3 relative to T1 while T2 was intermediate between T1 and T3 (P>0.05). semen color and pH were not affected (P>0.05) by treatments. It was therefore concluded that P. thonningii essential oil supplementation enhanced both haematological and fertility potential of the experimental rabbits.
