This study aims to produce a low-calorie ice cream with a higher nutritional value using red beetroot (Beta vulgaris L.). Four kinds of ice cream containing 5%, 10 % and 15% sucrose and single red beetroot (RB) ratio 15% and control (15% sucrose+ RB free) encoded as RB5, RB10, RB15 and C were produced respectively. The addition of RB increased pH and decreased the acidity (LA) and dry matter contents compared to control. Ash content was decreased depending on the sucrose ratio. While the lowest overrun value was determined in the RB10 sample (23.08%), the highest was in sample C (39.18%). The increasing of sucrose ratio generally increased the first dropping time and decreased the total melting time. The addition of sucrose reduced the viscosity and the highest viscosity values were observed in the sample RB5. While the lowest total phenolic content (TPC) was observed in the control sample (329.69 GAE mg/kg), the highest TPC was found in the RB5 sample (558.55 GAE mg/kg). Also, the lowest DPPH value was determined in the control sample (13.66% inhibition), the highest DPPH value was determined in the RB10 sample (27.98% inhibition). While fructose and glucose values decreased, sucrose values increased in the ice cream samples depending on the increasing of sucrose ratio.

This study aimed to determine the effect of ultrasonic sound waves on modifying the chemical structure of biodiesel to bring its physical properties closer to petroleum diesel. In this direction, safflower oil was selected because its fatty acid composition is similar to fatty acid esters of petroleum diesel and is a sustainable source. Refined safflower oil, the free fatty acid content of which was determined, was reacted with methanol under NaOH catalyst to perform the transesterification reaction. After biodiesel production, samples were incubated in an ultrasonic bath for 60, 120, and 180 minutes. FTIR, density, free fatty acid content, flash point, viscosity, and cloud point analyses investigated the effect of incubation times on biodiesel's chemical structure and properties. FTIR spectra showed that ultrasonic sound waves partially decomposed fatty acid methyl esters and increased the number of volatile components in biodiesel. The flash point of biodiesel has been associated with a decrease of 89°C, and the low flash point is expected to increase fuel efficiency. Kinematic viscosity values were measured in the 3.4583-3.5115 mm²/s range, and density values were measured in the 0.8820-0.8872 g/ml range. These values show that biodiesel complies with national and international standards. As a result, the ultrasonic bath process applied to biodiesel showed a similar result to chemical modification methods by affecting the structure of fatty acid chains. Thus, it brought the physical properties of biodiesel closer to petroleum diesel. It is seen that this method is a more efficient alternative for biodiesel production because it does not use additional chemicals, and the process is faster. In conclusion, by increasing the production of the drought-resistant safflower plant, sustainable energy resources will be contributed, while its waste can be evaluated as animal feed. Ultrasonicated safflower biodiesel can also be used as an efficient, environmentally and mechanically friendly alternative fuel source.

Improved malt barley production technology packages are not yet widely adopted in Ethiopia. Stakeholders, including brewers, malt factories, research institutes, and farmer-based organizations, have been collaborating and promoting new malt barley production technologies in order to boost the intensity of acceptance. The aim of this study was to find out the intensity of improved malt barley production technologies adoption in Arsi zones, Oromia region, Ethiopia. A stratified random sampling approach with multiple stages was employed to collect primary data from 384 malt barley household heads. The data was analyzed using descriptive statistics, and the intensity of adoption of improved malt barley production technologies was determined using an econometric Tobit regression model. The findings specified that the most adopted improved malt barley variety was Traveler (47.92%), which was followed in descending order by Iboni (14.58%), Sabini (9.38%), Grace (5.47%), Holker (4.43%), and 18.23% unnamed varieties. The Tobit model result also depicted that the intensity to which improved malt barley varieties adopted were affected by, taking into account factors including contract farming involvement, cooperative membership, off-farm income, size of livestock holdings, access to training, and mobile ownership. Enhancing farmers’ knowledge of the advantages of contract farming, income diversification, and mobile phone-based information delivery are among the many ways to support access to and accelerate the adoption of improved malt barley technology in the research area and beyond.

Milk traits of sheep are affected by many environmental and genetic factors. These traits are quantitative traits and are determined by many genes. This study aimed to investigate polymorphisms of milk-related Fatty-acid synthase (FASN), Stearoyl-CoA desaturase (SCD1), and solute carrier 27A3 (SLC27A3) genes in cross-bred Hamdani sheep. Blood samples were collected from 100 healthy cross-bred Hamdani ewes from the jugular vein into K3-EDTA-containing tubes. Genomic DNA was extracted using a commercial DNA isolation kit. PCR products of FASN (275 bp), SCD1 (225 bp), SLC27A3-P1 (341 bp), and SLC27A3-P2 (319 bp) were subjected to restriction fragment length polymorphism (RFLP) analysis using SSil (AciI), Cfr13I, AluI, and Hpy188III the restriction enzyme, respectively. However, all gene regions were found to be monomorphic. In the study, only TT, AA, AA, and GG genotypes were detected for FASN, SCD1, SLC27A3-P1, and SLC27A3-P2, respectively. Allele and genotype frequencies were 1.00 for all genotypes and alleles. Although this study did not reveal favorable genotypes in FASN, SCD1, and SLC27A3 genes that can be used for milk traits, more comprehensive studies with larger sample sizes should be conducted to investigate polymorphisms in cross-bred Hamdani sheep.

Faba bean (Vicia faba L.) is a significant member of the Fabaceae family, known for its high protein content and rich phenolic compounds essential for human nutrition. These phenolic compounds, which belong to the group of secondary metabolites, serve as important dietary components. Secondary metabolites, act as plant defence mechanisms and can fluctuate under stress conditions. Weeds negatively impact the growth of cultivated plants by competing for nutrients and creating a stressful environment. This study evaluated the effects of weeds on the yield and quality parameters of faba bean. Conducted in Sakarya, the research aimed to determine how weed control frequency affects the yield and some secondary metabolites of faba bean. The experiment used a randomized block design with four replications and included four faba bean genotypes: two registered varieties (Eresen-87 and Salkım) and two local populations (Bilecik and Sakarya). Weed control treatments; comprised weedy control, hoeing every 15 days, and hoeing every 30 days. Measured parameters included plant height (cm), number of pods per plant, number of seeds per pod, 1000 seed weight (g), dry seed yield (g), and DPPH radical scavenging activity (%). Data were analyzed using Duncan’s Multiple Range Test with SPSS, revealing statistically significant differences (p<0.05) in all measured parameters. The tallest plants were found in the Salkım×Control plot, while the shortest were in Sakarya×15. The highest number of pods occurred in Sakarya×30, and the lowest in Eresen-87×15. The highest number of seeds per pod was recorded in Bilecik×15, while the lowest was in all treatments of the Salkım variety and the Eresen-87×15 plot. The highest dry seed yield came from Bilecik×15, with the lowest from Eresen-87×30. DPPH activity peaked in Bilecik×Control, indicating significant differences in yield and nutritional content among faba bean genotypes. These findings indicate that different genotypes excel in various agricultural and nutritional characteristics, demonstrating that these differences can play an important role in shaping future production strategies.

This study was carried out to assess feed resources mineral composition and utilization of mineral soil in the Haramaya district of the East Hararghe Zone, Ethiopia. The survey data was collected from four kebeles using a semi-structured questionnaire from 80 respondents (20 from each kebele) selected randomly. Two natural pasture samples across the wet and dry seasons were collected using a quadrant from each season. Two maize and sorghum stover samples were collected for analysis at the end of harvesting seasons. Two mineral soil samples were collected from Lake Adelle and Small Abaya. Table salt (50%), mineral water (30%), and mineral soil (20%) were used as mineral supplements for livestock. Farmers obtain mineral soil from the licking area of the mineral soil and feed animals by hiking them in the licking area and taking the mineral soil into the home. Maize stover was deficient in Ca, P, Na, Zn, and Cu, while sorghum stover was deficient in P, Na, Mg, and Cu. During the wet season, natural pasture consists of higher (p<0.05) P, K, Cu, Zn, and Mn while Ca and Fe were higher (p<0.05) in the dry season. During wet and dry seasons, the Ca, P, Na, Mg, and K content were 14.53 vs 20.47, 1.51 vs 0.82, 0.38 vs 0.45, 4.01 vs 3.84, and 16.50 vs 6.40 g/kg, respectively. The Mn, Fe, Cu, and Zn contents were 365.14 vs 415.22, 477.78 vs 336.11, 8.48 vs 7.38 and 42.74 vs 16.94 mg/kg in wet and dry seasons, respectively. The mineral soil of both lakes was deficient in P and K, but high in Na and Fe. Supplementation of animals with deficient minerals in their feed is necessary in the study area and the mineral soil can be used as a mineral supplement for ruminants. However, an extension service is essential to improve mineral soil utilization in the study area.

Milk and dairy products mostly contain mycotoxins such as aflatoxin M1, aflatoxin M2, ochratoxin, cyclopiazonic acid, trichothecene, zearalenone, patulin. Mycotoxins in cheese are produced by certain types of fungi. These either directly contaminate the cheese or feed, or indirectly contaminate the milk used in cheese production. Aflatoxin, causes serious impacts on human and animal health, thus costs the world economy billions of dollars. The first legal regulation regarding aflatoxin M1 in Turkiye came into force in 1990. Subsequently, various legislations were published in 1997, 2002, 2008, 2011 and 2023. In this study, 60 publications were examined that investigate the presence of aflatoxin M1 in various cheeses in Turkiye in the last 50 years (1973-2023). In the studies, aflatoxin M1 was detected in almost all cheeses, and only a few were found in rates exceeding the Turkish Legal Limits. Researchers stated different limits for aflatoxin M1 in cheese. To minimize the presence of aflatoxin M1, the following recommendations should be considered. Developing new detection methods, enacting new legal regulations, increasing the frequency of legal inspections, improving the production, transportation and storage conditions of milk and dairy products, improving feed quality, increasing awareness of the health effects of aflatoxin M1.

In this study, Bacillus subtilis natto was encapsulated in alginate, either coated with or mixed with xanthan gum as a supplemental component. The encapsulated bacteria were then evaluated for their survival in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF). The results showed that B. subtilis natto biomass had a thrombolytic ability compared to the control sample. The viability of encapsulated B. subtilis natto was improved in which alginate 2.5% (w/v) had a high encapsulation efficiency, and there was no difference between the samples with or without the xanthan gum supplement. In the SGF and SIF tests, the viability of B. subtilis in samples supplemented with xanthan gum was higher than in samples that contained only alginate. Additionally, there was no significant difference in viability between the samples that mixed xanthan gum with alginate and those that were coated with it. The results indicated that adding xanthan gum is necessary to increase alginate's protective effect on B. subtilis natto.

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.
