Mahdeb Nadia | Khadidja Attafi | Souha Bouhouhou | Allouni Rima | Abdelouahab Bouzidi
Ruta montana L. is an annual aromatic plant of the family rutaceae. Quantitative analysis of the methanolic crude extract of Ruta montana L. yielded 8.43%, whereas the qualitative analysis revealed the presence of alkaloid or coumarin. The Litchfield and Wilcoxon method calculated the LD50 of the crude methanolic extract of Ruta montana L. in Wistar albino female rats at 393.18 mg/kg. This allows the plant to be classified as moderately toxic. The subacute toxicity study of the methanolic crude extract of Ruta montana L. in female Wistar albino rats treated with 100 mg/kg (≈ 1/4 LD50) and intraperitoneally showed a significant increase in body weight of the rats treated at the 4th week. Animals treated and sacrificed after 30 days showed a disturbance of the relative mass of the organs. Biochemical parameters of hepatic function assessment showed a significant increase in PAL with elevation of AST and ALT, whereas those of renal function revealed a significant decrease in creatinine with an increase in urea. Hematologic parameters recorded a decrease in RBC, HGB and HCT. The histological sections of the treated rats reveal the existence of blood congestion in the central veins and liver tissues, foci of necrosis and steatosis in the liver, blood congestion and some glomerular atrophy in the kidneys, as well as blood congestions and developed follicles without oocytes in the ovaries.

The present study examined the physicochemical properties, antioxidant activity (DPPH, ABTS, and FRAP), and sensory properties of aronia marmalades prepared with different cooking methods (CM) (boiled (B) and pressure-boiled (PB)) by adding sugar (S) and stevia prebiotic fiber sweetener (SP). Ash, reducing sugar, sucrose, viscosity, L*, a*, b*, C*, and H° values, and total sugar content of aronia pulp and marmalades differed significantly by cooking method and sweetener type (ST). Hydroxymethylfurfural could not be detected in aronia pulp and marmalades. Concerning CM, TPC (total phenolic content) and TMA (total monomeric anthocyanin) values were found to be significantly higher in PB cooking than in the B cooking method. On the other hand, TFC (total flavanoid content) was statistically higher in boiled marmalades. According to CM, the DPPH antioxidant activity of marmalades was significantly higher in B marmalades. The TPC, TMA, TFC, and antioxidant properties of marmalades differed sigficantly by ST. The TPC of marmalades prepared with SP addition was higher than that of S-added marmalades and control. According to ST, whereas the antioxidant activities (DPPH, ABTS, and FRAP) of S and SP-added marmalades were lower compared to the control, the antioxidant activities determined by DPPH and ABTS among S and SP-added marmalades were higher in SP-added marmalades. The panelists gave the highest scores to BSC (boiled S-added marmalade). Considering the overall acceptance scores, the second highest score was given to BST (boiled SP-added marmalade). In other words, in terms of sensory evaluation, boiled marmalades received higher overall acceptance scores, while PBST (PB SP-added marmalade) received the lowest scores. According to these results, astringency components decrease with cooking in an open vessel. Furthermore, it can be said that sugar masks this astringent taste.

Sunulan çalışmada solunum yolu hastalığı belirtileri gösteren koyunlarda genel fiziksel ve özel klinik muayene bulgularının, tam kan sayımı sonuçlarının ve nazofarengial sürüntü örneklerinin incelenmesi amaçlandı. Çalışmada solunum yolu hastalığı şikâyeti bulunan bir İvesi koyun sürüsünde (n:62) alt solunum yolu hastalığı belirtileri tespit edilen 18 adet dişi koyun kullanıldı. Hasta koyunların yaş kayıtları tutuldu, genel fiziksel muayeneleri gerçekleştirildi. Özel klinik muayene parametrelerinin her biri kendi içinde skorlandı. Hasta koyunlar akciğer oskultasyon skor sonuçlarına göre “Hafif Hasta (n:11)” ve “Orta Hasta (n:7)” şeklinde iki gruba ayrıldı. Hasta hayvanlar da dahil bütün koyunlardan antikoagülantlı ve antikoagülantsız kan örnekleri alındı. Antikoagülantlı kan örneklerinden tam kan sayımı yapıldı. Hasta (n:18) ve sağlıklı (n:6) koyunlardan mikrobiyolojik ve virolojik analizler için steril swap ile nazofarengial sürüntü örnekleri alındı. Kan (n:62) ve nazofarengial sürüntü (n:24) örneklerinden Bovine herpesvirus tip 1, Respiratorik sinsityal virus (RSV), Parainfluenza 3 (PI-3) ve Pestivirus varlığına yönelik analizler gerçekleştirildi. Hafif hasta ve orta hasta koyunlar karşılaştırıldığında, yaş, dakikadaki kalp atım sayısı, klinik durum gözlem skoru, MCH Pg, MCHC g/dL verilerinde gruplar arasında anlamlı farklılık (P<0,05) tespit edildi. Sağlıklı ve hasta olan koyunların nazofaringeal örneklerinde baskın olarak sırasıyla Staphylococcus spp., Streptococcus spp. ve E. coli bakteri türleri izole edildi. Klinik olarak sağlıklı görünen bir koyundan Klebsiella spp. izole edilirken, yalnızca bir hasta koyundan M. haemolytica izole edildi. Sağlıklı görünen bir koyunda serolojik olarak BoHV-1-spesifik antikor tespit edildi. Sonuç olarak saha şartlarında uygulanabilecek en kolay ve en hızlı yöntemler arasında yer alan akciğer oskultasyon bulguları ve nazofarengial sürüntü sonuçları ile muhtemel etiyolojik etken ve hastalık durumu hakkında öngörüde bulunulabilir. Bu sayede ekonomik değere sahip bu hayvanlarda erken muhtemel tanı ile tedaviye başlanarak ekonomik kayıplar azaltılabilir.

Nigeria’s dry onion production amounted to 1.38× 106 metric tonnes (t) in 2020. Roughly 50% of yearly production do not reach the table. An option lies in converting fresh dry onions to dry onion powder to mitigate postharvest losses. This study explores the possibility of producing dry onion powder from fresh dry onions using a pre-tested locally fabricated direct-mode solar tent dryer. The outcome of processing revealed a product yield of 8.09%, while there was no statistically significant difference between the measured proximate contents of powder and fresh dry onions (t(28)=0.04, p=0.97, two-tailed; eta square=5.71 × 10-5). Overall, the production of dry onion powder was not water neutral. About 4.5 cubic metres (m3) of freshwater per tonne of cleaned onions were needed during processing. Dry onion powder production (from field to table) freshwater use amounted to 31879.6 m3/t. Converting 40 - 60% of national average dry onion production (2000-2020) to dry onion powder would consume 14.05 - 21.08 × 109 m3 of Nigeria’s freshwater. This study affirms that dry onion powder production is technically feasible and can help to minimise dry onion production postharvest losses in Nigeria.

Agricultural support is a crucial way to overcome the difficulties of long agricultural production process, lack of capital and low productivity. Moreover, the fact that increasing the supply is not possible in a short while makes agricultural support more important. Different agricultural structures of countries imply different agricultural support values. This paper examines the simultaneous relations between agricultural support and agricultural value added in the six developing countries with the highest agricultural production value. Simultaneous equation systems are estimated by Two-Stage Least Squares method using annual data for the 2002-2018 period. The findings suggest that there is a simultaneous positive and statistically significant relationship between agricultural value added and agricultural supports.

Rice is the most important staple food crop and plays a vital role in ensuring national food security in Nepal. Rice yield is largely determined by nitrogen management strategy and improving the effectiveness of nitrogenous fertilizer for grain production has long been a challenge. A field experiment was conducted in the sandy loam soil of Lumle, Kaski, Nepal in 2019 and 2020 to assess the effect of neem oil-coated urea (NCU) and common urea (CU) with varying levels of nitrogen (N) on rice yield and nitrogen use efficiency (NUE). The experiment with 7 treatments comprising the combinations of two types of nitrogen source (CU and NCU), three N levels (50, 100, and 150 kg/ha) and one control treatment without N, were allocated in a randomized complete block design with three replications. Increased nitrogen rates up to 100 kg/ha supplied through NCU significantly improved grain yield, yield components, and nitrogen use efficiency of rice. Application of NCU reduced nitrogen fertilizer use by up to 33 % while producing maximum yield and significantly increased agronomic nitrogen use efficiency (ANUE) and nitrogen partial factor productivity (NPFP) compared with CU. This suggests that the use of NCU with an optimum rate can be a viable option for appropriate N management in rice production.

This study was carried out on 114 Brown Swiss cattle reared in intensive conditions at Ataturk University Food and Livestock Application and Research Center and at the private cattle farm found in Erzurum province. Genotypic structures were examined in terms of Insulin-like growth factor (IGF)-II gene locus and the distribution of genotypes and allele frequencies of the cattle concerning the genes were determined. The identified Insulin-like growth factor (IGF)-II genotypes were associated with milk yield traits such as actual milk yield, 305-day, and daily milk yield. Insulin-like growth factor (IGF)-II genotypes were determined by using the Polymerase Chain Reaction (PCR)- Restriction fragment length polymorphism (RFLP) method from blood samples taken from the cattle. The CC, CT, and TT genotype frequencies of the Insulin-like growth factor (IGF)-II gene found in the population were 41 (34%), 65 (54%), and 14 (12%), and the frequency of the C allele and the T allele was found to be 0.61 and to be 0.39. The general averages of actual true milk yield, 305-day and daily milk yield were 4317±272.9 kg, 5277±240.7 kg and 18±0.9 kg, respectively, while CC, CT and TT genotypes 4168±515.8, 3756±321.7 and 5382±600.3 kg, respectively. As a result, correctly identified IGF-II genotypes were detected by using the PCR-RFLP method in the blood samples obtained from Brown Swiss cattle. Genotype and allele frequencies determined for IGF-II gene polymorphism can be considered sufficient to demonstrate the genotype diversity of the race. According to the Hardy-Weinberg genetic equilibrium test, the distribution of genotype frequencies of the cattle was observed in equilibrium.

This study evaluated the possibility to use pomegranate peel: an agro-industrial bay product as a conservative agent for fruit juice. Extraction of active compounds of. Punica granatum L. peels was made by maceration with ethanol and the evaluation of antioxidant and antimicrobial activity were conducted using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and disk diffusion method in agar medium, while self-life tests of orange juice monitoring the pH, total soluble solids, titratable acidity, cloud value, browning index and total mesophilic germs were conducted during 18 days. The results highlighted that pomegranate peel extract (PPE) showed a higher phenol and flavonoid content and strong antioxidant activity with an inhibitory concentration (IC50) of 6.22 μg / mL, as well as the antimicrobial activity indicated a higher inhibitory effect. Furthermore, shelf life tests showed a significant effect on browning index, titratable acidity, and lowering of microbial growth during storage compared to the controls, while pH, total soluble solids, and cloud value are not affected. These results allow us to consider pomegranate peel extract as a potential conservator for healthy and sustainable food.
