Anaplasmosis, a vector-borne haemoparasitic disease, poses a significant threat to animal health. This study investigated the prevalence and associated risk factors of anaplasmosis in goats within the Chattogram district of Bangladesh. The research was conducted at the SA Quadery Teaching Veterinary Hospital (SAQTVH), Chattogram Veterinary and Animal Sciences University (CVASU), involving observations of 202 goats. Blood samples were collected from the ear veins of 44 goats. Thin blood smears were prepared, stained with Giemsa, and examined under a microscope. Statistical analysis was performed using Chi-square tests in SPSS Statistics version 26. The study found that goat rearing systems significantly influenced infection rates (P < 0.05). Anaplasmosis was more prevalent in goats displaying pale mucous membranes and symptoms such as fever or weakness (P < 0.05). To mitigate the disease, strategic control measures, including vector reduction and routine health monitoring, are recommended.

This research was conducted to determine the presence of Prunus necrotic ringspot virus (PNRSV) and Apple mosaic virus (ApMV) that can cause infection in rose (Rosa spp.) plants grown in Konya province. For this purpose, field and laboratory studies were carried out in areas where roses are mostly grown for landscaping purposes, and infection rates were calculated with the data obtained. The hypothesis of the study is that roses in Konya province may be infected with PNRSV and ApMV and the presence of these viruses can be determined. In line with this hypothesis, various rose growing areas in Konya province were selected as the research area. During the field studies in 2023, guided sampling was carried out and 94 leaf, branch and flower samples were collected from different rose varieties. The collected samples were tested for determining of PNRSV and ApMV infections by Double Antibody Sandwich (DAS) ELISA method, which is one of the serological testing methods in the laboratory. As a result of the tests, it was revealed that the single infections of PNRSV and ApMV were present in 12 and 11 samples of rose plants in Konya province. The total infection rate of both viruses in the province was calculated as 24.47%. Also, PNRSV+ApMV mixed infections were detected in 2 samples. In this study, the infections of PNRSV and ApMV on roses in Konya province were determined for the first time by serological methods. These results will serve as an important source of information for rose producers and agricultural engineers in the region and will allow the development of strategies to control the spread of viruses and minimize infections.

The effect of vesicular arbuscular mycorrhizal (VAM) infection on growth and P nutrition in Maize (Zea mays, cv.DDH hybrid) were assessed in Oxisol pot experiment. Maize was grown inoculated with spores of VAM fungi Glomus mosseae or non-inoculated. Low soluble ferrous phosphate (FePO4.4H2O) was added to the mycorrhized and non-micrrohized maized. The dry weight of mycorrhized plants with added phosphate (P) were higher than in mycorrhized plants without added P or non-mycorrhized plants with added P. The amount of P in the soil samples from pots with mycorrhizal plants fertilized with P was evidently smaller than those in samples also fertilized non-mycorrhizal plants. The percentage of P was higher in tissues of fertilized mycorrhial plants than in those mycorrihzed plants without or nonmycorrhized plants with added low-soluble P. These results indicated that plants in VAM symbiosis mobilize P better from low-soluble P than non-mycorrhized plants. | En condiciones de casa de malla se evaluó el efecto de la infestación con micorrizas vesículo arbusculares (VAM) en la asimilación de P por plantas de maíz (Zea mays, cv.DDH hybrid) cultivadas en un Oxisol. Como micorriza se utilizó el hongo Glomus mosseae. En ambos tratamientos (con micorriza y sin ella) se aplicó fosfato ferroso (FePO4.4H2O). La producción de MS de maíz fue mayor cuando se aplicaron el hongo + la fuente de P. La cantidad de P en el suelo con este tratamiento fue menor que en el suelo fertilizado pero sin aplicación del hongo. En las hojas de las plantas las mayores concentraciones de P se observaron igualmente en el tratamiento micorriza + aplicación de fertilizante.

A hybrid camel Tülü (Bactrian male x Dromedary female F1) males are preferred in camel wrestling, which is a culture unique to Anatolia. In this study, changes of live weight (LW), daily weight gain (DWG), and body measurements (BMs) of Tülü calves in the first 6 months of age in a farm in Aydın province, Türkiye, were determined as well as developing equations to estimate LW from body measurements. Tülü calves average birth weight (BW) was 34.7±1.80 kg and reached 175.3±3.38 kg at the age of 6 months with a 0.768±0.03 kg DWG during this time. Although the monthly total weight gains and monthly DWG averages of the calves in the first 6 months were similar, the changes in monthly LW and BMs were statistically significant (P<0.01). Abdominal girth (AG) alone can be used to predict LW in the analysis performed to estimate LW from body measurements by stepwise regression (R²=95.62%). In conclusion, Tülü calves had relatively high growth rate in their first six months of age, and unlike other livestock species, instead of hearth girth (HG), AG that includes the hump can be used to estimate LW of Tülü calves.

The global dilemma of waste management and food scarcity require novel solutions that fulfill both environmental concerns and nutritional requirements. To address these significant problems in a sustainable manner, this research investigates the possibility of producing single cell protein (SCP) from sugarcane bagasse, an abundant industrial waste product in the presence of Aspergillus niger strain. The production of SCP was further optimized by inducing variations in Physico-chemical properties to increase the protein yield. These parameters include temperature, pH, fermentation time, inoculum size, carbon and nitrogen sources. The results of this study revealed that A. niger showed maximum production of biomass (24.0±0.02%) at the temperature of 25°C after 7 days of incubation time with the pH adjusted to 5. In conclusion, this multidisciplinary strategy emphasizes how essential biotechnology is to be advancing the idea of how sugarcane bagasse could potentially be used as a beneficial asset to help feed the world's expanding population.

Considering the plant richness of Chapada do Araripe, Brazil, the pequi (Caryocar coriaceum Wittm) extractivism occurs as an important activity that affects the economy and social life of the main cities of Cearense Cariri, although there is little knowledge about its current situation and sustainability perspective. The aim of this work is to collect information regarding actor relationships involved in the pequi extractive activity, relating them to the sustainability dimensions. This study was carried in the Barreiro Novo camping site, located in the state highway CE 060 in the Jardim-Ce municipality. Semistructured questionnaires were used with pequi collectors to establish a socioeconomic profile, besides using the participant observation method, pictures and content analysis in order to relate and identify the sustainability in this environment. Extractivism activity in the Chapada do Araripe region is something cultural, which has a special vision towards environmental issues that generates income for extrastivist families. However, the region needs policies for improving social conditions (water and sanitation in the camping site) and keeping the tradition without missing the environmental perspective. | En Chapada do Araripe, región del Brazil con una gran riqueza vegetal, el extractivismo del pequi (Caryocar coriaceum Wittm) es una importante actividad que abarca la economía y la vida social de las principales ciudades del Cariri Cearense.

Ömer Ertugrul
The present study aims to evaluate the energy production potential from walnut (Juglans regia L.) residues, specifically pruning waste and shell biomass, in Kırşehir province, Türkiye. Data collected between 2019 and 2023 were analyzed to quantify the biomass availability and its corresponding energy potential across various districts in the region. The findings reveal that total biomass production from pruning residues increased from 1220.36 t in 2019 to 1322.69 t in 2023, resulting in an energy potential growth from 19,904.02 GJ to 21,573.11 GJ. A similar trend was observed in shell biomass, which rose from 483.11 t to 523.62 t, resulting in an energy potential increase from 9164.60 GJ to 9933.12 GJ. The Kaman district consistently dominated, accounting for over 55% of the total energy potential, while Boztepe and Çiçekdağı exhibited the lowest contributions. The total energy production potential from walnut residues in 2023 was estimated at 31,506.22 GJ (31.51 TJ), corresponding to an annual electricity generation capacity of approximately 8751.74 MWh. The study emphasizes the higher energy potential of pruning residues compared to shell biomass and highlights regional disparities in biomass availability, underscoring the need for targeted strategies to optimize resource utilization. The findings indicate that the utilization of walnut residues for bioenergy purposes has the potential to substantially mitigate fossil fuel dependency and to promote sustainable energy development in the region.

Nüfus artışı, hızlı ve plansız kentleşme ile birlikte kent içerisindeki yeşil alanlar başta olmak üzere diğer tüm doğal alanlar yapılaşma nedeniyle niteliğini kaybetmiş veya azalmıştır. Kentte yaşayan insanlar için bu alanların azalması ve niteliğinin ortadan kalkması rekreatif ihtiyaçların karşılanamamasına neden olmuştur. Bu durum kent içinde veya yakın alanlarındaki tabiat parklarının, mesire alanlarının ve ormanlık alanlarının daha kıymetli hale gelmesine imkan tanımıştır. Bu çalışmanın amacını, Adıyaman ili, Gölbaşı ilçesi sınırları içinde kalan Gölbaşı Gölleri Tabiat Parkı’nın Gülez yöntemine göre rekreasyonel potansiyelinin belirlenmesi oluşturmaktadır. Gülez yönteminde, rekreasyonel alanın peyzaj değeri, iklim değeri, ulaşılabilirlik durumu, rekreatif kolaylık ve olumsuz etkenlerin puanlandırılmasıyla rekreasyon potansiyeli hesaplanmaktadır. Bu hesaplamaya göre, Gölbaşı Gölleri Tabiat Parkı’nın rekreasyonel potansiyeli toplamda “67” puan alarak “yüksek” kategoride değerlendirilmiştir. Gölbaşı Gölleri Tabiat Parkı’nda gerçekleştirilen arazi çalışmaları sonucunda, yöntemde belirtilen bazı ögelerinin nitelik olarak eksik olduğu ve olumsuz etken ögelerinin oldukça fazla olduğu tespit edilmiştir. Gölbaşı Gölleri Tabiat Parkı’nın rekreasyonel faaliyet potansiyeli tespit edilenden daha fazladır. Sahadaki olumsuz etkenlerin azaltılmasıyla alanın rekreasyonel faaliyet potansiyelinin “19” puan daha artırılabileceği, bu sayede Gölbaşı Gölleri Tabiat Parkı’nın toplam puanın “86” olarak potansiyelinin “çok yüksek” sınıfına ulaşabileceği öngörülmektedir.

In this study, the effects of pre-slaughter fasting periods (8, 12, and 16 h) on stress levels, body weight loss, slaughter, carcass, and meat quality characteristics were investigated in broiler chickens with different growth rates (medium and fast-growing). In the experiment, 15 male and 15 female broilers each from the ANADOLU-T A1 (medium growing) dam line and ROSS-308 hybrid (fast growing) at 42 days of age were used. Body weight losses did not differ significantly among fasting periods, but medium-growing broilers exhibited higher body weight losses across all fasting groups (P<0.05). The carcass yield was higher in fast-growing broilers (P<0.05), while abdominal fat ratios were higher in medium-growing broilers (P<0.05). The amount of residual feed in the gizzard, digestive system, and gizzard ratios decreased with increasing fasting duration (P<0.05). Digestive system ratios also differed between genotypes (P<0.05). An increase in breast ratio was observed with longer fasting periods (P<0.05). On the other hand, the fast-growing genotype had higher breast ratios, lower wing ratios, lower back ratios, and lower neck ratios (P<0.05). Fasting periods did not significantly affect the L*, a*, and b* color values of breast and thigh meat, but differences between genotypes were significant, with higher values observed in the fast-growing genotype (P<0.05). Breast pH values did not differ among fasting periods but were higher in the fast-growing genotype (P<0.05). Thigh pH values, however, varied significantly between fasting periods and genotypes (P<0.05). The medium-growing genotype had higher thigh pH values, and thigh pH increased with longer fasting periods (P<0.05). White striping and woody breast scores in breast muscles were higher in the fast-growing genotype, with partial increases observed as fasting duration increased. In conclusion, the results indicate that a 12-h pre-slaughter fasting period is sufficient for digestive tract clearance and carcass quality. However, meat quality defects in fast-growing genotypes should be monitored.

This study aimed to evaluate the biochemical and nutritional profiles of three cauliflower cultivars—Valentena, Carotena, and Snow White—focusing on chlorophyll, carotenoids, anthocyanins, vitamin C, flavonoids, phenolics, and antioxidant activity. Uniform curds were harvested at 60 days post-sowing from Baratia, Dumuria, Khulna, and analyzed at Khulna Agricultural University. Valentena exhibited the highest chlorophyll content (40.06±0.39 µg/100g FW chlorophyll a, 28.98±3.35 µg/100g FW chlorophyll b), superior lycopene (8.71±0.38 µg/100g FW) levels. Carotena showed the highest total carotenoid content (60.52±1.76 µg/100g FW) and β-carotene (26.99±0.44 µg/100g FW), while Snow White had the lowest values across most parameters. Valentena also led in anthocyanins (101.56±3.9 mg/L FW) and total flavonoids (79.56±10.36 mg/100g FW), with Carotena having the highest vitamin C content (60.05±2.93 µg/g FW). DPPH assays indicated that Valentena showed the most effective antioxidant (IC50 = 43.65±3.56 mg/mL FW), followed by Carotena and Snow White. Hierarchical clustering and pricipal component analysis (PCA) revealed distinct biochemical profiles: Valentena and Carotena shared similarities in carotenoids and antioxidant activity, whereas Snow White differed significantly. Linear discriminant analysis identified lycopene, chlorophyll b, and β-carotene as major differentiators, highlighting the diverse nutritional and antioxidant properties of these cauliflower varieties. The findings highlight the potential of Carotena and Valentena for health-conscious consumers seeking nutrient-rich, antioxidant benefits in functional meals.

While shellfish species are widely consumed due to their nutritional advantages, they are also among the top eight food items for food-borne allergies. Five distinct thermal processing techniques were applied to the crustacean to investigate the tropomyosin level variations caused by heat processing. Fresh shrimp and prawns were utilized as controls for the determination of allergen-encoding genes. Prior to molecular analysis, the proximate composition and acidity of raw and processed samples were also performed. The yield and purity of DNA were also determined. Melting curve and gel electrophoresis tests verified the existence of allergen-coding genes. Thermal processing procedures affected the proximate composition, particularly the total protein and fat concentrations, according to the findings. Following the heat treatment, the pH levels decreased, particularly in the grilled samples. There were also significant differences in the quantity and quality of the extracted DNA. Regardless of crustacean species, the tropomyosin-encoding gene was detected in both fried and grilled samples. These findings demonstrated that RT-PCR identification and validation of the crustacean allergy gene by gel electrophoresis might be a reliable approach for the thermally treated shrimp and prawn samples. This study shows that investigating the allergen coding gene might provide a viable way for detecting food-borne allergens in other thermally processed food items, which are becoming more concerned about food safety.

En un invernadero del Centro Internacional de Agricultura Tropical, CIAT, Cali (Colombia) se evaluó la aplicación de cinco inóculos de hongos micorrícico arbusculares, HMA: Kuklospora colombiana, Gigaspora margarita, Glomus manihotis y la mezcla de estos con y sin esterilización, en sustrato sin desinfectar (SD) y desinfectado (D) sobre variables de rendimiento (biomasa aérea y radical, longitud radical), colonización por HMA y concentración foliar de nutrientes en la gramínea Melinis minutiflora Beauv., con el objetivo de seleccionar los inóculos más eficientes. Se utilizaron como unidades experimentales materos de 13.5 x 16.0 x 14.0 cm. El sustrato empleado fue suelo procedente de un Inceptisol con baja disponibilidad de nutrientes, tamizado y mezclado con arena. Los inóculos de Gi. margarita y Gl. manihotis presentaron los mejores resultados en la acumulación de biomasa aérea y radical, longitud radical, porcentaje de colonización micorrícica y concentración de elementos. Kuklospora colombiana presentó efectos inhibitorios sobre las variables evaluadas. La condición del sustrato SD favoreció la acumulación de biomasa aérea y radical y la concentración de fósforo (P) en la biomasa aérea, además, estimuló la longitud radical de M. minutiflora. La concentración de N, K, Ca y Mg en la biomasa aérea fue mayor en el sustrato D. Los resultados muestran que Mellinis minutiflora con inoculación HMA es promisoria para la recuperación de suelos degradados. | The effect of five inocula of arbuscular mycorrhizal fungi (AMF) on the grass Melinis minutiflora Beauv. was investigated under greenhouse conditions at the International Center for Tropical Agriculture (CIAT), Cali, Colombia, with the aim of selecting the most efficient AMF inocula. Non-disinfected (ND) and disinfected (D) substrates were studied. Inocula were: Kuklospora colombiana, Gigaspora margarita, Glomus manihotis and a mixture of those three species of AMF with and without sterilization. Yield parameters were aerial and radical biomass, root length, mycorrhizal colonization and N, P, K, Ca, and Mg concentrations in the aerial biomass. Pots measuring 13.5 x 8.0 x 14.0 cm were used as experimental units. Inceptisol soil, with low nutrient availability, previously sieved and mixed with sand was used as substrate. Gi. margarita and Gl. manihotis inocula showed the best results in the accumulation of aerial and root biomass, root length, mycorrhizal colonization and concentration of elements in the aerial biomass, while Ku. colombiana presented inhibitory effects on the variables evaluated. ND substrate condition increased accumulation of aerial and radical biomass and P concentration in the aerial biomass, also stimulated root length of M. minutiflora. Aerial biomass had higher concentrations of N, K, Ca, and Mg in D substrate. Mellinis minutiflora is a promising grass species for rehabilitation of degraded soils in combination with arbuscular mycorrhizal fungi inoculation.

Spartium junceum L. is a plant traditionally used for different medicinal purposes. While limited research data explicates its antioxidizing ability, interest in this plant is induced mainly due to its possible role, especially against stress-causing oxidative effects. The objectives of this study were to compare antioxidant activity in flowers and leaves of Spartium junceum L., as well as time under different storage conditions implemented for antioxidative mechanisms. Spartium junceum L. plants were obtained from the Kahramanmaras, Turkey region; subsequently, the flowering and leaf parts of the plant were separated and analyzed. Plant homogenates were prepared, and the activities of SOD and CAT enzymes, as well as MDA levels, were determined using spectrophotometric methods. Enzyme activity upon storage at +4°C, -20°C, and -70° temperature enzyme samples were carried out separately and operated for less than one month in our laboratory. Flowers exhibited higher SOD and CAT activities than leaves. Flowers also showed higher levels of MDA. It may be due to the structural and biochemical differences, where flowers experience extra oxidative stress. The optimal enzyme retention under storage conditions was at -70°C, and a decrease in temperature increased the stability of this biocatalyst. In contrast, MDA levels increased at low temperatures at total capacity. The antioxidant properties of the flower extract had stronger antioxidant potential than those of the leaf part, which also means that chemically active substances show much higher concentrations in this plant section. Storage temperature significantly affects the stability of enzymes, and it was stated that low temperatures mainly maintain antioxidant activity. The results obtained from this study recommend Spartium junceum L. as a valuable antioxidant food resource.

This study aimed to evaluate the effects of soybean hay supplementation on growth performance, feed intake, and nutrient utilization in local sheep fed grass hay as a basal diet. Twenty-five yearling intact male local sheep were assigned to five dietary treatments in a completely randomized block design: 100% concentrate (+ve control; T1), 75% concentrate + 25% soybean hay (T2), 50% concentrate + 50% soybean hay (T3), 25% concentrate + 75% soybean hay (T4), and 100% soybean hay (T5). The study lasted 90 days, followed by a 7 day digestibility trial. Dry matter intake did not differ significantly (P>0.05) among treatments, with values ranging from 939.06 to 1,049.19 g/day. Organic matter intake was significantly higher (P<0.05) in T1, T2, T3, and T4 compared to T5. Soybean hay inclusion exceeding 50% resulted in significantly greater ash intake (P<0.001). Crude protein (CP) intake was highest in T1 (84.82–109.56 g/day; P<0.01), while T1, T3, and T4 exhibited higher digestible CP and metabolic body weight (P<0.05) than T2 and T5. Apparent CP digestibility was significantly higher (P<0.01) in T1 and T3 compared to T2, T4, and T5. Final body weight and average daily gain were significantly higher (P<0.05) in T1, T3, and T4 compared to T2 and T5. T1, T2, T3, and T4 also showed significantly greater total body weight gain and feed conversion efficiency than T5 (P<0.05). Economic analysis revealed marginal rates of return of 1.21 for T3 and 1.51 for T4, both exceeding the minimum acceptable rate for farmers. Considering both growth performance and economic feasibility, T1 (100% concentrate) and T4 (25% concentrate + 75% soybean hay) are recommended as viable supplementation strategies to enhance sheep productivity.
