2024
Oluwafemi Emmanuel Ogundahunsi | Isaac Olatunde Olaoye | Precious Akintobi Fabunmi
In Nigeria, before the removal of subsidy on kerosene in 2016, the product was accessible to low-income individuals and is intended to be used as a fuel for cooking, lighting, or heating. Recently, kerosene is rapidly vanishing from rural families and it is becoming inaccessible due to its ever-rising cost. Therefore, to ease the hardship of low-income individuals to have access to high thermal efficiency cookers with affordable fuel, a study was carried out to determine the thermal efficiency and fuel consumption rate of a pressure cooker fueled with a blend of waste vegetable oil and kerosene. Based on this, a low-cost pressure cooker was developed with locally available materials to aid the atomization of fuel during cooking. Along with this, vegetable oil was blended with kerosene to enhance the quantity of kerosene used to fuel the pressure cooker. This cooker fueled with blends of vegetable oil and kerosene was analyzed for its thermal efficiency and fuel consumption rate and was also compared to the conventional kerosene stove. The result shows that the constructed pressure cooker has a thermal efficiency of 52% which is 20% more than the conventional kerosene stove but the developed pressure cooker consumes more fuel (48.62 ml) than the conventional kerosene wick stove (33.78 ml). Though the pressure cooker consumes more fuel, the thermal efficiency per time with respect to the fuel consumed is much better than conventional kerosene stoves which makes the developed cooker cheaper and more affordable both to low-income earners and for rural dwellers.

This study was carried out to obtain morphometric measurement values of tongue and esophagus in Swiss Albino and Balb-c mice, to examine the biometric differences of these measurements between sexes and groups. Thirty-two mice, 16 Swiss Albino (8 males, 8 females) and 16 Balb-c (8 males, 8 females), were used for this study. Mice anesthetized with the ketamine-xylazine combination were fixed by the technique. The tongue and esophagus of the mice were carefully dissected and removed. Then, morphometric measurements of the dissected organs were taken, and statistical analysis was performed. When the morphometric measurement values were examined, it was seen that all of the measurement values obtained from both Swiss Albino and Balb-c mice were higher in males than in females. Statistically significant differences were observed between the groups in all morphometric measurement values of tongue and esophagus in both mouse races (p<0.05). Additionally, positive and significant correlations were found between morphometric measurement values of tongue and esophagus in both groups according to gender. Differences in morphometric measurement values of the tongue and esophagus were determined between genders and groups in Swiss Albino and Balb-c mice. Furthermore, this study provided basic morphometric data that will benefit various scientific fields related to the tongue and esophagus in these animals, especially anatomical studies.

The aim of this study was to investigate the effects of partially replacing the commercial soybean meal (SBM) with a home-treated, locally produced raw-full fat soybean (RFFSB) in the diets of broilers. A 3×2×2+1 factorial arrangement was used to conduct this feeding trial. A test ingredient (RFFSB) was differently soaked (0, 6 or 12 hrs), drained, boiled (25 or 35 min) and sundried. Following this, it was hammered to pass through a 0.2-mm sieve, then 12 experimental diets were formulated, replacing the SBM by such a home-treated-RFFSB at 50 or 75%. The control diet didn’t contain any RFFSBN. Totally 13 experimental diets were prepared and every treatment was replicated 3 times and 10 chicks per replicate. The results revealed that replacing the commercial SBM by a treated RFFSB had no significant interaction effects on any measured parameter. However, soaking and then boiling it (RFFSB) had significant (P<0.05) interaction effect on the BWTG (1-13d and 14-28d). When increasing the soaking time, the FI (feed intake), BWTG (body weight gain) and feed efficiency were significantly (P<0.05) decreased. When increasing the boiling duration, both FI and feed efficiency (14-28d) were improved. But, when increasing the replacement rate of RFFSB, the feed efficiency was deteriorated. Broilers fed on both control and diets, containing a non-soaked RFFSB had higher (P<0.05) BWTG (1-13d). Birds fed on diets containing RFFSB that was soaked for the longest period (12 hrs) had significantly lower BWTG. Birds fed on diets, containing prolonged boiling duration had significantly (P<0.05) higher BWTG and feed efficiency. There was no interaction (P> 0.05) effect on both carcass yield and cut-products. Neither increasing a boiling time nor a replacement rate had (P<0.05) any influence on the WT (weight) of the carcass. Birds on both control and on non-soaked RFFSB diets had better WT of carcass products. There was no interaction (P>0.05) effect on organ developments. However, increasing the soaking-duration significantly (P<0.05) reduced the organ developments. Therefore, it is concluded that commercial SBM can be replaced by a non-soaked, but boiled raw soybean in diets of broilers.

It is critical that Bangladesh faces water scarcity during the dry season, affecting lentil (Lens culinaris Medik.) yield and some yield components during seedling and flowering stages. Thus, a two-factorial pot experiments (The experiment comprises Factor A: three fertilization levels i.e. F1 = Control [inorganic], F2 = poultry litter-based compost [20 ton/ha], F3 = poultry litter-based compost [30 ton/ha]; Factor B: two irrigation levels such as W1 = 100% field capacity [FC] and W2 = 70% FC) were designed at Hajee Mohammad Danesh Science and Technology University, Dinajpur, from November 2018 to April 2019. And it was investigated how the poultry litter-based composts affected the morpho-physiology, yield and yield components of the lentil (BARI Masur-4) variety under different irrigation stress levels. Obtained results revealed that the tallest plant (30.7 cm at 75 DAS) and maximum branch number per plant (14.1 at 65 DAS), leaf chlorophyll a (0.30 mg/g), highest RLWC (70.28%), lowest proline content (1.57 µ moles g-1 FW), maximum number of pods per plant (39.4 at 75 DAS) and total grain yield (3.62 kg/m2) were recorded from compost F3 (poultry litter-based compost 30 tons/ha) with W1 (100% FC). Results also showed that the yield contributing attributes and yield of lentils were drastically reduced by water stress conditions with different rates of fertilization. In drought conditions (W2 = 70% FC), F3 (30 ton/ha poultry litter-based compost) fertilization produced the highest plant height (30.20 cm at 75 DAS), number of branches (11.5 at 65 DAS), stem dry weight (0.35 g), lowest proline (3.88 µ moles g-1 FW), highest pod number per plant (33.1), weight of 100-seed (2.36 g), total grain weight (2.77 kg/m2), harvest index (58.84%) compared to other fertilizations (F1 and F2). In summary, F3 (30 tons), a compost made from poultry litter, provides better soil conditions under drought conditions compared to F1 and F2 in the year of 2018-19 at the 0 and 20 tons/ha, respectively under the field conditions.

Watermelon is a widely cultivated cucurbitaceous crop with economic and dietary significance. The plant's ability to reproduce effectively relies on the harmonious growth and maturation of both its male and female flowers. At the farm level, determining the exact amount of ethylene required to regulate the development and sexual expression of individual floral buds remains uncertain, despite the known influence of exogenously applied ethylene on these processes. The goal of the research was to explore how the ethephon doses influence vegetative characteristics, sex expression, and watermelon yield. The experiment, employing a one-factorial Randomized Complete Block Design (RCBD) comprising five treatments and four replications, was conducted in a farmer's field in Buttabari, Jhapa. Using R-stat software, the data were analyzed at a 5% level of significance. Treatment consisted of Ethephon with four doses namely; 100ppm, 200ppm, 300ppm, 400ppm, and a control. Ethephon application was done twice, once at the two true-leaf stages and another at four true-leaf stages. The study revealed that plant height decreased with ethephon compared to the control, reaching a minimum of 280.1 cm at 400 ppm and a maximum of 307.1 cm in the control. Additionally, the highest branch numbers were observed with ethephon at 200 ppm. The plot treated with 200ppm ethephon was found to be more effective than alternative doses at increasing the total number of female flowers, bearing 15.25 female flowers per plant. Control (166.50 per plant) and 400 ppm (150.00 per plant) had the highest and lowest male flower counts per plant, respectively. A maximum yield of 25.12 t/ha and a minimum yield of 19.1 t/ha were determined at 200 ppm and control, respectively. Hence, farmers are found to benefit from ethephon doses of 200 ppm.

This study aimed to show the effect of acetamiprid, a neonicotinoid insecticide, on B-cell lymphoma 2 (Bcl-2) gene expression, which plays an important role in apoptotic mechanisms in liver tissue. The study consisted of four groups in total, in which three doses of acetamiprid (5, 10, and 15 mg kg-1) were administered, together with the negative group, in which no substance was administered. Liver tissues resected from mice sacrificed by cervical dislocation after 14 days of acetamiprid administration by gavage were fixed in a 10% formaldehyde solution for histological and immunohistochemical analyses and blocked in paraffin after routine tissue follow-up, and sections were stained with haematoxylin-eosin and immunostaining. Histological analysis revealed normal liver tissue in the control group; whereas, sinusoidal dilatation, vasodilatation, and necrosis and steatosis in the parenchyma were found in the acetamiprid-treated group at an increasing rate depending on the dose amount. The immunoreactivity of Bcl-2 in liver tissue was observed in the sinusoidal epithelium. Bcl-2 immunoreactivity was observed severely in the control and 5 mg kg-1 groups and moderately in the 10 mg kg-1 and 15 mg kg-1 acetamiprid-treated groups. Bcl-2 immunoreactivity was observed homogenously in the region from the central vein to the Kiernan’s space. It was observed that acetamiprid used in the study showed a toxic effect on liver tissue, affected bcl-2 expression, an important biomarker in apoptotic pathways, and induced a dose-dependent decrease in bcl-2 immunoreactivity.

Yunus Emre Boğa | Nasir Abdallah | Kadriye Kurşun | Mikail Baylan
Diğer hayvancılık kollarında olduğu gibi kanatlı hayvan yetiştiriciliğinde de işletmelerin masraflarının en önemli kısmını yem masrafları oluşturmaktadır. Özellikle, gelişmekte olan pek çok ülkede önemi artan, bulunması zorlaşan ve pahalı hale gelen yem masrafları birçok küçük ölçekli kümes hayvancılığı işletmesinin kapanmasına ve kümes hayvanı üretiminin toplam maliyetinin artmasına neden olmaktadır. Bu durum, kanatlı ürünleri olan tavuk eti ile yumurta fiyatlarının artmasına, gelişmekte olan ve az gelişmiş pek çok ülkede birincil hayvansal protein kaynağı olan kanatlı eti ve ürünlerinin tüketiminin ve alım gücünün düşmesine, yetersiz ve dengesiz beslenme gibi pek çok olumsuz duruma yol açmaktadır. Yem masraflarını düşürmek, dolayısıyla kanatlılardan elde edilen ürünlerin maliyetini azaltmak için alternatif bir yem madde arayışı çok önemlidir. Anavatanı Asya olan Moringa oleifera, besin maddeleri açısından oldukça zengin olan ve soya fasulyesi, mısır gibi geleneksel hayvan rasyonunda kullanılabilen yem maddelerinin bir kısmının yerini alabilecek bitkilerden biridir. Afrika ve Asya’da Moringa oleifera’nın kanatlı performansı ve ekonomik verimlilik üzerindeki etkisini araştıran pek çok araştırma yapılmıştır. Belirli bir oranda Moringa tohumlarının veya yapraklarının rasyona dahil edilmesinin, üretim performansını, et kalitesini, hayvan sağlığını ve refahını artırdığını, ancak daha yüksek miktarlarda kullanıldığında ise hayvanın yaşamını zorlaştırıp, üretim parametrelerinin azalmasına yol açtığı bildirilmiştir. Yapılan çalışmalarda; kanatlı rasyonlarına %5-10 arasında Moringa ilavesinin performansı olumlu etkilediğini gösterirken, rasyona %10’un üzerinde Moringa ilave edildiğinde ise hayvanların performansının kötüleştiğini belirtmişlerdir. Bu derleme, alternatif bir yem maddesi olan Moringa oleifera’nın yapraklarının ve tohumlarının kanatlı hayvanların performansı üzerindeki etkisini belirlemek amacıyla hazırlanmıştır.
