Abstract: Rabbits are popular pets and they are susceptible to injuries. Though various types of dressing materials have been available, the comparative analysis of the effectiveness of various dressing materials on external wound healing in rabbits is limited. So, the objective of this investigation is to assess the efficacy of Zinc oxide tape, Povidone Iodine, and Polyurethane film as wound dressing materials. Twenty rabbits were divided into four groups, each consisting of five rabbits: group A was the control group, group B was provided with zinc oxide tape, group C received 10% povidone iodine dressing, and polyurethane film was administered in group D. Each animal underwent three linear incisions, each 2 cm in length, in the flank area. The control group did not receive any dressing for external wound healing, whereas Groups B and D were administered zinc oxide tape and polyurethane film on day 0, and Group C got daily povidone iodine dressing. Morphological and histopathological changes of the wound sites were observed during the experiment. Full thickness skin tissue samples were obtained on days 3, 7, and 14 post-application of wound dressing materials. The wound length and width (1.28 ± 0.06 cm and 0.059 ± 0.0126 cm) were significantly decreased (ANOVA, p < 0.001, η² = 0.755 for length; η² = 0.737 for width) in 10% povidone iodine treated group compared to the zinc oxide tape group (1.46 ± 0.05 cm and 0.12 ± 0.06 cm), the polyurethane film (1.63 ± 0.03 cm and 0.193 ± 0.01 cm) and the control group (2.44 ± 0.05 cm and 0.251 ± 0.007 cm). The histological study revealed that 10% povidone iodine group exhibited the fastest reepithelialization, followed by zinc oxide tape, polyurethane f ilm and control group. The study demonstrated that regular dressing with 10% povidone iodine promoted enhanced wound healing compared to zinc oxide and polyurethane film, making it appropriate for wound dressings in rabbits.

Abstract: This paper explores the shoreline evolution of Kutubdia Island, situated in the southeast Bay of Bengal, over 36 years (1988-2024). This is mainly to determine long-term changes in the shoreline by using geospatial analysis, which is done by using Digital Shoreline Analysis System (DSAS) and Weighted Linear Regression (WLR) to establish a trend in the change of erosion and accretion. The paper also examines how shoreline movement correlates with vegetation health in order to determine how it helps stabilize the coastline in terms of the Normalized Difference Vegetation Index (NDVI). Findings show that a considerable amount of erosion occurred on the coastline, as 88.57 percent of the transects had evidence of shoreline erosion, resulting in a total loss of land of more than 4,990 meters. Regions that had reduced cover of vegetation were identified as prone to erosion, and this justifies the significance of restoring the vegetation in preventing further erosion. To add to this, the research makes projections on the shoreline location in 2034 and 2044, which demonstrate that there is still a loss of land, especially on the lower side of the island. On the basis of such findings, a sustainable coastal management plan has been advanced, which has an emphasis on ecological reinstatement, including the plantation of mangroves and community-customized strategies. The article identifies a pressing need to implement special measures to safeguard vulnerable areas and guarantee a sustainable future of sustaining the ecological resiliency in the coastal environments, serving as a reference to other exposed coastal geographies susceptible to environmental attrition.

Abstract: This study was conducted to investigate the present status, reproductive performance, and health management of commercial turkey farms in Bangladesh. Thirty-three farmers were interviewed with a structured questionnaire. Males operated 96.97% of farms, of them 48.48 % farmers were between the age of 31 to 40 and 48.48% hold a bachelor’s degree. Turkey raising was secondary to other jobs, 51.51% farmers were in business, 39.39% in paid service, and 6.06% were students. No farmers had previous experience in turkey farming and only 3.04 % read relevant literature. American Black (33.33%) and White Holland (24.25%) were the leading breeds. Mixed enterprises combining meat, egg, and poult production dominated (42.42%), followed by hatcheries (27.27%), meat farms (18.18%), and layers (12.12%). Daily production averaged 32.27±0.96 eggs/farms weighing 63.94±0.93 g. Birds were marketed at the age of 5.75±0.27 months, with mean undressed and dressed weights of 8.77±0.40 kg and 6.23±0.29 kg, respectively. Among the hatcheries, 70.58% achieved fertility rates and 58.82% achieved hatchability rates within the range of 81-90%. Although no farm used commercial turkey rations, 90.91% prepared their own mixed diets; pellets were used by only 3.04%. All farmers routinely added medications to feed/water and vaccinated birds. Diseases were prevalent in every farm, headed by turkey pox (51.51%), Newcastle disease (21.21%), mycoplasmosis (15.15%), and fowl cholera (12.13%). Economically, 81.81% reported no profit and 78.78% planned to quit due to high feed prices, poor technical support, weak marketing, and volatile prices. Targeted government interventions such as farmer training, provision of quality feed, and development of stable market channels could transform turkey farming into a sustainable source of income for unemployed youth and marginalized women of Bangladesh.

Abstract: The cotton variety CB14 was cultivated in the experimental plots and the effect of the insecticides, namely Actos 1.8EC, Asatap 75SP, Tundra 20SP, Talstar 2.5EC, Confidor 70WG, Spike 25WG, Siren 25.9%EC, Ripcord 10EC, and Panel 50SC in comparison to untreated plots were evaluated for jassid (Amrasca devastans) inhibition. Among the insecticides, Panel 50SC treated plots exhibited the highest plant height (123.0 ± 0.8cm), number of branches (13.5 ± 0.4a), number of leaves (66.4 ± 0.4a), sympodia (9.4 ± 0.2a), plant weight (281.5 ± 1.0 g), boll weight (14.0 ± 0.3 g) along with diameter (3.8 ± 0.3 cm) and length (5.8±0.0 cm) of the bolls, GOT (36.2±0.3), lint index (8.0±0.3) values. Panel 50SC revealed the lowest abundance of jassid, at 1, 3, and 7 days after treatments were 0.6±0.7, 1.0±0.5 and 1.6±0.4 per shoot, respectively. The laboratory-based mortality test revealed that after 24, 48 and 72 hours, Panel 50SC had the highest mortality rates (23.3 ± 1.6%, 46.6 ± 4.4% and 60.0 ± 5.0%, for each case). The study showed the highest yield under Panel 50SC (1.4 ± 0.9 t/ha) followed by Confidor 70WG (1.2 ± 0.7 t/ha), Spike 25Wg (1.2 ± 0.4 t/ha) and Actos 1.8EC (0.9 ± 0.7 t/ha).

Abstract: Food safety refers to ensuring that food does not cause harm when prepared and consumed as intended. It remains a major public health concern in both developed and developing countries, as food contamination continues to pose significant health and economic burdens. This cross-sectional study aimed to assess the Knowledge, Attitudes, and Practices (KAP) related to food safety among 185 nursing students at TMSS Nursing College, Bogura, Bangladesh. The majority of respondents were female (81.6%), aged 22 (48.6%), from rural areas (36.2%), and low-income families (51.4% earning 16,000–17,000 BDT monthly). While 75% of the students displayed positive attitudes toward food safety and reported good practices such as consuming family-cooked meals (38.9%), over half demonstrated poor knowledge of proper food. Family influences a prominent role in shaping food safety behavior. Although the results are consistent with national findings, where food safety knowledge adequacy stands at 47%, the study highlights an urgent need for curriculum reforms to incorporate structured food safety education. It recommends targeted policies, community outreach programs, and empowerment of nursing students to become effective advocates for food safety in resource-limited settings.

Abstract: Hematology serves as a valuable diagnostic tool in aquaculture for assessing fish health, monitoring environmental conditions, and evaluating responses to nutrition and management practices. Therefore, this study aimed to compare the hematological characteristics of three economically significant fish species such as Gangetic mystus (Mystus cavasius), stinging catfish (Heteropneustes fossilis), and walking catfish (Clarias batrachus) obtained from wild and cultured habitats. Wild and cultured fish specimens were collected from the Turag river and a commercial fish hatchery, respectively. Blood samples were extracted from the caudal peduncle and stored in heparinized tubes for hematological examination. The results demonstrated that the cultivated environment showed increased dissolved oxygen, pH, and temperature, along with elevated electrical conductivity, whereas the wild environment presented higher concentrations of nitrite and ammonia. Among the hematological parameters, no significant differences (p > 0.05) were observed in HCT and MCHC content between the wild and cultured fish. However, WBC and RBC varied significantly (p < 0.05) across all the species in both environments. Lym, Gra, Hb, and PLT counts in stinging catfish varied significantly between natural and cultured habitats. For Gangetic mystus, Lym, MCV, and MCH differed significantly (p < 0.05) while, walking catfish exhibited insignificant variations in terms of any hematological parameters except WBC and RBC. These findings underscore that hematological parameters are sensitive to environmental conditions and can serve as reliable indicators of fish health. The species-specific variations observed further suggest that different fish respond uniquely to wild and cultured environments, highlighting the importance of species-based assessments in environmental monitoring and aquaculture management.

Abstract: Planting methods affect growth duration, yield components and yield of rice, although the effects are highly variable on location, variety and the growing season. Therefore, present study aimed to evaluate the effect of planting methods on growth duration, yield components and yield of Aus rice varieties at Barishal region. Treatments of the experiment consisted of three varieties (Binadhan-19, Binadhan-21, BRRI dhan48) and four planting methods (direct seeding, sprouted seeding, seed dibbling, seedling transplanting) and assigned in randomized complete block design. Results showed that the variety Binadhan-21 took shortest duration for 50% flowering (65 days) and maturity (91 days) when sprouted seed was used as planting method. Binadhan-21 planted with sprouted seed also exhibited lower plant height (105.20 cm), maximum number of effective tiller per hill (19.0), higher panicle length (23.73 cm), filled grain per panicle (63.73), and higher weight of 1000 grains (25.67 g) which contributed to higher yield (4.07 t ha-1) as compared to other varieties and planting methods. Planting of Binadhan-21 with sprouted seed during Aus season is therefore suggested for better yield of rice at Barishal region of Bangladesh.

Abstract: Bangladesh, with its large population and heavy reliance on agriculture, is particularly vulnerable to the impacts of climate change. These changes complicate traditional pest management strategies, as pests that were once seasonal or localized may now thrive year round or spread to new areas. Unpredictable weather conditions can affect pest control practices, including the effectiveness of chemical treatments and the timing of pest monitoring. This article explores the impact of climate change on pest management in Bangladesh, focusing on the vulnerabilities of the agricultural sector and the need for adaptive strategies. It discusses how climate-induced changes in temperature, rainfall, and humidity can facilitate the spread of pests, the introduction of invasive species, and the outbreak of pest populations. These changes also enhance the reproduction of pests like rice stem borers, aphids, and fruit flies, which are already damaging key crops. As pests become difficult to control with conventional methods, leading to greater reliance on chemical pesticides, which carry long-term environmental and health risks. Agricultural production and food security in Bangladesh are at serious risk due to the spread of these arthropod pests and diseases. Global warming, irregular rainfall, and extreme weather events are disrupting current pest management methods, such as cultural, biological, and chemical approaches. Therefore, promoting sustainable agricultural practices like integrated pest management, climate-smart agriculture, and biotechnological approaches is essential for mitigating the impacts of climate change on pest outbreaks. Priority should be given to the development of resistant varieties, conservation of natural enemies and development of effective forecasting models.
