A Graphical Approach as Multiple Comparison Method for the Balanced and Partially Balanced Lattice Designs 全文
2025
Soner Yiğit
This study proposes a reliable and easy understandable statistical solution for the selection of varieties in the balanced and partially balanced lattice experiments, which are widely used in plant breeding studies. For this purpose, the Analysis of Means (ANOM) was adapted to the balanced, simple and triple lattice designs and an R function is developed for it. The adapted ANOM approach was compared with the Tukey, Duncan and Fisher’s LSD tests with respect to the actual type I error rate in all of the balanced, simple and triple lattice designs. In addition to this, the ANOM approach and Tukey test were examined comparatively using a hypothetical example. According to the simulation results, LSD and Duncan could not maintain the actual type I error rate at 5.00% under any conditions. This situation became more dramatic with the increase in the number of groups. While the actual type I error rate for LSD and Duncan tests varied between 54.36%-100.00% and 37.49%-99.96%, respectively, for ANOM and Tukey tests it varied between 4.64%-6.08% and 4.62%-6.45%, respectively. ANOM and Tukey tests were quite successful in terms of maintaining the actual type I error rate. However, since the number of groups in lattice designs was quite high, the given hypothetical example showed that it would be more understandable to use the ANOM method.

The aim of this study is to examine the essential oil ratios and components of fresh and dried peppermint leaves cultured in Kırşehir ecological conditions. To obtain essential oil from the leaves of the peppermint (Mentha piperita L.), it was subjected to hydrodistillation for 3 hours using a Clevenger type apparatus. GC-MS analysis was performed with the Shimadzu QP2010-Ultra GC-MS system. Relative percentages of separated compounds were calculated from total ion chromatograms. Identification of the components of peppermint essential oil was based on Wiley and NIST mass spectral library. The essential oil percentages obtained from fresh and dried peppermint leaves were determined as 0.84% and 2.6%, respectively. The major components of the essential oil of fresh Mentha piperita L. leaves were determined as menthol (43.28%), menthone (19.68%), eucalyptol (7.60%), pulegone (3.41%), β-Caryophyllene (2.10%), Germacrene-D (1.82%) and veridifluorol (1.1%). The major components of the essential oil of dried peppermint leaves were determined as menthol (45.95%), menthone (19.00%), eucalyptol (8.06%), pulegone (2.23%), β-Caryophyllene (2.72%), Germacrene-D (2.21%) and veridiflorol (0.81%). The highest essential oil ratio, the highest menthol and the highest menthone ratio were obtained from dried peppermint leaves. Results, it was determined that there were significant differences between the essential oil ratios and components of dried and fresh leaf peppermint (Mentha piperita L.) cultivated in Kırşehir ecological conditions.

2025
Hakan Erdem | Türker Savaş
Inbreeding increases homozygosity, resulting in a loss of alleles and lower genetic variation than the parental population. In a small population, this low genetic variation and homozygosity can quickly lead to adverse effects. This study was conducted on a flock of pigeons with 32 adult pigeons. A disease characterized by dyspnea, anorexia, vomiting and sudden death has occurred in birds. Mortality and morbidity were recorded during the outbreak. The inbreeding coefficient was determined in the flock, with pedigree records going back 12 years. Although not significant, the inbreeding coefficient of dead birds are lower than that of symptomatic or healthy birds. It is also seen that there is no statistical significance in terms of inbreeding depression in morbidity or mortality status. The result indicated that inbreeding depression in morbidity and mortality was not observed in this particular disease case.

Kubra Gerbaga Ozsemir | Murat Karabağlı
In this research, the interpretations of dental disease in domestic rabbits (Oryctolagus cuniculus) suffering from miscellaneous disorders with the use of radiographic anatomical reference lines; additionally, clinical examinations of these cases were presented. The measurements were made on the images of rabbit cranium skull radiographs (n=25). In the examination of incisors, malocclusion (n=19), abnormal prolongation (n=11), penetration of the palatal bone cortex (n=10), and fractures (n=6) were detected. Retrograde elongation in maxillar cheek teeth (n=20), alveolar penetration in mandibular cortex (n=20), root resorption (n=9), and cheek teeth malocclusions (n=20) were detected in the examination of cheek teeth. The most common complaints assigned to the presented patients were diarrhea, mandibular swelling, abnormal elongation of teeth, epiphora, tooth breakage, and loss of appetite. All rabbits suffering from dental disease were also assessed for eye disorders, and tooth-related eye problems were determined in 9 cases. In two cases was more than one problem. Distribution of disease was determined as follows; epiphora (n=6), dacryocystitis (n=2), conjunctivitis (n=2) and exophthalmos (n=1). In addition to a detailed physical examination, radiographic evaluation is important for diagnosis of dental diseases in rabbits. The long mouth cavity with limited opening and similar characteristics of rabbit mouth make it difficult to examine and intervene; in this case, radiographic reference lines offer an important advantage.

2025
Hatice Nur Kılıç | Mustafa Boğa
In dairy cattle, the dry period cation-anion balance is a critical factor influencing the animal's health and productivity. The cation-anion balance of a ration is contingent upon the anionic and cationic ions present and may assume either a negative or positive value. During the dry period, the optimal cation-anion balance is negative. The administration of anionic salts or anionic ration during this period has been demonstrated to mitigate the risk of milk fever and prevent the development of numerous metabolic disorders. Furthermore, the administration of anionic substances during this period has been demonstrated to influence milk yield, fertility and milk fat. An excessive cation ratio in the ration can cause metabolic problems, including metabolic acidosis, milk fever, and metabolic alkalosis, which is characterised by a decrease in pH and the presence of urine. Therefore, according to the studies, it is recommended that the diet be prepared in a way that the cation-anion balance is negative in the dry period (between -100 to -200 mEq/kg DM).

The modern intensive agriculture system relies on the heavy use of chemical fertilizers for food production, neglecting the health of the soil. To explore the alternative nutrient source provided by Azotobacter, a free-living nitrogen-fixing bio-fertilizer, a field experiment was conducted at the Gaindakot – 8, Nawalpur in the inner Terai of Nepal during March-June 2023 to study the effect of Azotobacter inoculation on three different maize varieties. The effect was examined on the soil fertility parameters such as Nitrogen (N), Phosphorus(P), Potassium(K), pH, and organic matter (O.M). Five levels of nutrient sources; Control, Farmyard Manure/FYM (10-ton ha-1), Azotobacter only, Azotobacter + FYM and Azotobacter + NPK (120:60:40 kg ha-1 RDF) varieties; Local Pahelo, Rampur Composite and Rampur Hybrid-14 were tested in Two Factorial Randomized Complete Block Design with three replications. Results showed a non-significant difference in the mean values of N, P, O.M., and pH whereas K content was significantly influenced under the different varieties. Rampur Hybrid-14 (256.64 kg/ha) showed the highest soil K level whereas Rampur Composite (173.12 kg/ha) showed the lowest. The highest N content was recorded in Azotobacter only (0.140%) followed by Azotobacter + FYM (0.137%) and lowest in control (0.132%). Similarly, the maximum percent of organic carbon was recorded in the nutrient source Azotobacter only (2.80) which is on par with the nutrient source Azotobacter + FYM (2.75). There was a significant influence of the FYM on the maximum residue of the Azotobacter population (180.2×10-3 cfu/gm). The status of O.M., N, P, K, and pH improved positively with the Azotobacter application.

Processed chicken meat products are more susceptible to oxidative deterioration which reduces the quality and safety of the product, therefore, the need to include antioxidants during processing order delay its processes. Chicken meat (from live broiler birds procured from the Teaching and Research Farm, University of Ibadan) was ground through a 5 mm plate of a meat mincer. Ingredients such as red pepper, black pepper, garlic, onions, salt, refined vegetable oil (Grand soya oil®) ice flakes and Lemon Grass Leaf Powder (LGLP) were added and mixed thoroughly with chicken meat for homogeneity. There were four treatment groups: T1 = (0g LGLP), T2 = (2g LGLP), T3 = (4g LGLP), T4 = (6g LGLP). Each batch was oven cooked separately and replicated three times. Proximate composition (%), sensory characteristics (9-point hedonic scale), Thiobarbituric Acid Reactive Substances (TBARS MDAµg/g) were assessed and data generated were analysed using ANOVA @ P<0.05). Moisture 51.24 (6gLGLP) was significantly higher than 52.69 (4gLGLP), 53.04(2gLGLP) and 54.69 (0gLGLP); fat 16.09 (2gLGLP) is similar with 17.19 (4g LGLP) and lower than 15.89 (0gLGLP) but lower than 17.48 (6gLGLP) (P<0.05). Crude protein 19.52 (4gLGLP) is similar to 18.10 (2gLGLP) and 19.18 (6gLGLP) but significantly higher than 17.85 (0gLGLP). The hardness 2983.81kg (0gLGLP) and 3442.86kg (2gLGLP) were similar but lower than 5395.55kg (4gLGLP) and 5523.17kg (6gLGLP) (P>0.05). Chewiness 2790.83kg (0gLGLP) is not different from 3413.43kg (2gLGLP) and 5315.52 (4gLGLP) but higher (P<0.05) than 5523.10kg (6gLGLP) (P>0.05). No significant variation exists in the sensory characteristics among chicken meatballs. The TBARS 1.74 (6gLGLP) is lower than 1.80 (4gLGLP), 1.86 (2gLGLP) and 1.84 (0gLGLP). Utilisation of different levels of lemongrass leaf powder in chicken meat balls production increased the nutrition and improved the lipid oxidation stability of the product during refrigerated storage.

2025
Lilu Kumari Magar | Gandhiv Kafle
Agroforestry is a system that combines household and community level food production ecosystem services along with income security. It has potential of carbon sequestration and puts a positive impact on balancing greenhouse gases. The research was carried out to assess the variability of carbon stock under the agro-forestry systems in Churiya range at Rakshirang Rural Municipality of Makwanpur district of Nepal. Thirty households were sampled for this study; ten households from each of three different systems namely, Agrisilviculture, Silvopasture and Homegarden for data collection. Simple random sampling was used for the sample plot selection from the selected agroforestry systems for biomass and soil carbon estimation. Each system consisted of ten sample plots. Diameter and height of all trees with diameter at breast height greater than 10 cm were measured. The diameters of the trees were measured at standard height, i.e., diameter at breast height. Above ground biomass, below ground biomass and soil organic carbon were summed to determine the total carbon stock in the agroforestry systems. Collected data were analyzed through tabular analysis, and volume and biomass estimation of the trees. Total carbon stock was found higher in Silvopasture system (32.41t/ha), 28.58 t/ha in Agrisilviculture system and 30.71 t/ha in Homegarden system. Results have shown the potentiality of agroforestry systems for carbon sequestration. Such systems need to be promoted for their efforts by encouraging them with some subsidized input support, financial support or some capacity building trainings by the government.
