Therefore, both consumers and producers must pay close attention to the physical and cooking characteristics of grains. The present study was conducted to evaluate the physical and cooking quality characters in twenty popular Bangladeshi boro rice genotypes along with one japonica rice genotype. A high degree of significant variation was observed for all the characters studied. Genotypes BRRI dhan55, BR16, BRRI dhan57, BINA dhan-6 and BINA dhan-14 has the maximum length of grain before cooking (L1). BRRI dhan36, BRRI dhan57, BRRI dhan55 and BINA dhan-6 were the best performer in terms of grain length after cooking (L2). BRRI dhan57 and BRRI hybrid dhan1 were best for width of grain before cooking (W1). BRRI dhan57, BRRI dhan29 and BRRI dhan36 were exhibited minimum width of grain after cooking (W2). Yukihikari, BRRI hybrid dhan3 and BRRI dhan36 were best for grain elongation ratio. Highest grain length/width ratio before cooking (L1/W1) was observed in genotype BRRI dhan57, BRRI hybrid dhan1 and BINA dhan-14. The highest grain length/width ratio after cooking (L2/W2) was recorded in genotype BRRI dhan57 and BRRI dhan36.  Best genotype for percent water uptake (WU %) after cooking was BRRI dhan28 (180%). The best genotypes for solid in cooking water (SCW) were BRRI dhan36 (0.897%), BRRI dhan28 (0.956%), Yukihikari (1.043%) and BRRI dhan29 (1.048%), respectively. The prominent performer genotypes for CT were BRRI dhan58 (18.38 minutes) followed by BR 14 (19.12 minutes), BRRI dhan28 (20.00 minutes) and BRRI dhan57 (19.82 minutes). Best genotypes for amylase content (AC) BRRI dhan28 (24.93%), BRRI dhan55 (24.91%), BRRI dhan59 (24.90%). Most of the rice genotypes had found low cooking time (GT) except BRRI dhan57, BRRI dhan59, Yukihikari which shows intermediate gelatinization temperature (GT). The comparative information about physical and cooking qualities of rice might be used as reference to develop high grain quality rice cultivars in future.\u0000Res. Agric. Livest. Fish.

The purpose of this paper was to analyze skill training using a simulator in the venipuncture method and investigate its impact. Twenty Intern Veterinary students were randomly chosen from Sylhet Agricultural University's 23-batch DVM program. They were separated into two groups. One group (n=10) was exposed to a simulator before practicing on a live animal, while another (n=10) was not exposed to the simulator. They worked with a live animal. Students in the experimental group demonstrated a 50% skill efficacy. The control group demonstrated inferior skill, with 25% efficacy. The difference between groups was statistically significant (p<0.05). The experiment was carried out using a simple methodology and easily accessible resources to benefit other educational institutions and lessen the negative impact on live animals. Understanding the anatomy, physiology, and behavior of the species from whom the sample is being collected is critical for minimizing the risk of injury associated with venipuncture in these species. A physician must be aware of the benefits and drawbacks of venipuncture, the volume of blood that can be safely obtained, and the patient's preferred manner of getting the sample. Simulated skill training is a teaching strategy that aims to provide students with early education, enhance their confidence and skill development, and maximize process success while minimizing obstacles.\u0000Res.

To mitigate these risks, researchers have turned their attention to pesticide-free production methods. This study aimed to assess the market opportunities for pesticide-free vegetables (PFVs) through determining consumers’ preferences and willingness to pay (WTP), along with identifying factors influencing consumers' WTP decision in three major cities of the country, namely Dhaka, Khulna, and Mymensingh. Employing a multistage cluster sampling method, 150 samples were selected and data collection utilized the android-based app Kobo through direct interviews. The contingent valuation method (CVM) and double-bounded dichotomous choice model (DBDC) were used to estimate WTP and preferences while ordered logit model were employed to identify influencing factors. The findings indicated that over 90% of consumers in Mymensingh and over 92% in Dhaka and Khulna were willing to pay a premium for pesticide-free tomatoes and brinjal. Additionally, more than 18% and 19% of consumers expressed willingness to pay a 20% premium for brinjal and tomato, while over 39% were willing to pay for both a 10% premium. The study revealed that factors such as age, sex, education, household size, and income significantly influenced consumers’ WTP decisions, with age showing a negative correlation, while education and income were positively associated with interest in consuming pesticide-free vegetables. Overall, the study underscores the increasing demand for pesticide-free vegetables in urban areas, emphasizing the need for governments and stakeholders to develop supportive policies for sustainable market development.\u0000Res.

The study was carried out from August 2022 to July 2023 to reveal the existing aquatic resources and their composition, along with diversity, richness, and evenness indices. A comprehensive list of 57 distinct fish species has been documented, spanning across 8 orders, 22 families, and 42 genera. Within these, the Cypriniformes order exhibited the highest diversity in terms of both species count and observed individuals. Among the fish species inhabiting the Mathabhanga river, approximately 29.83% are considered threatened in Bangladesh, comprising 14.04% categorized as vulnerable (VU), 14.04% as endangered (EN), and 1.75% as critically endangered (CR). Overall values of the diversity index ranged from 2.45 to 3.15, richness was 3.81 to 6.17, and evenness index was 0.72 to 0.84. The investigation revealed that fish biodiversity in the Mathabhanga River has been steadily decreasing. This study suggested that fisheries should be managed through community-based fisheries management, establishing fish sanctuary, water pollution control, maintenance of fishing gear, and the implementation of the Fish Act for the sustainable management of fish biodiversity in the Mathabhanga River.\u0000Res.

Many marine fish population parameters were not investigated because of their low commercial value. Therefore, the primary goals of this study were to determine the size frequency, length-weight relationship (LWR), length-length relationship (LLR), and Fulton’s condition factor (Kn) of two tropical ponyfishes from Saint Martin’s Island. From March to April 2022, specimens were caught using fixed purse nets. A total of 409 specimens of P. aureus and K. daura were measured to determine size frequency, LWRs, LLRs, and Fulton's condition factor. For P. aureus, the maximum total length (TL) of 12.9 cm sets a new record. The LWRs for P. aureus and K. daura were highly significant (p<0.001), where the coefficient of determination (r2) was 0.985 and 0.869 for P. aureus and K. daura, respectively. The estimated slope (b) for P. aureus and K. daura were 3.147 and 2.986, respectively. The LLR equations were TL = 1.1089 SL + 0.2689 for P. aureus and TL = 0.6792 SL + 3.3309 for K. daura. The Kn value had no significant difference between the species of different length classes for P. aureus (0.97-1.40) and K. daura (1.19-1.26). There has never been any prior reporting of LWRs or length-length relationships (LLRs) for P. aureus in literature or FishBase.

To ensure human rights for all and to develop human resources through an educated workforce, inclusive education is must for physically challenged students. Higher education is considered as a way to gain much knowledge where the institution's environment plays an important role in the amplification of knowledge. The study obtained students' perception of existing facilities for physically challenged students in higher education institutions and essential measures that should be taken to make them human resources. Students indicated that teachers' and friends' attitudes are satisfied in both two institutions but, a little more concern for administrative authority is needed for environmental and service facilities as well as inclusive education.\u0000Res.

However this phenomenon can be thwarted occasionally if appropriate anticoagulant with storage times is not maintained properly. This research aims to compare and explore the effect of anticoagulants (such as ethylene diamine tetra acetic acid and heparin) and storage time on the hematological parameters in indigenous goats. Twenty goats were enrolled and raised for this purpose. Bloods were collected into two different tubes containing EDTA and heparin and analyzed immediately to evaluate the basal value. All tubes were divided into two aliquots and stored at 4°C and 25°C and were analyzed again at the 24th and 48th hours of collection. The statistical analysis of this result showed that there was no significant difference (P>0.05) in the anticoagulant’s effect on the hematological parameters. RBC, Hb, PCV, MCV, MCH, MCHC, total WBC, and Platelets except ESR decreased gradually along with the storage time of up to 48 hours compared to the basal value. The hematological parameters were reduced more significantly (P<0.05) when stored at 250C rather than 4°C indicating that the parameters remain in better condition in refrigeration. The samples should be stored at 4°C rather than room temperature and be used within 24 hours because the storage time modify the analyzed results. These findings demonstrate that both of the anticoagulants (EDTA and Heparin) show reliable results, therefore it can be used to store blood samples for any diagnostic purpose.\u0000Res. Agric.

Nitrogen, being an inert gas, is assumed to ensure the preservation of the quality of fresh mushrooms. In our study, freshly harvested mushrooms were carefully packaged in polypropylene (PP) bags both with and without nitrogen gas. Which were then stored both at room temperature and in the refrigerator.  Throughout the storage period, the changes in seven quality parameters - total soluble sugar (TSS), browning index (BI), weight loss, pH, moisture content, odor, and texture were assessed at two-day intervals. The results revealed no significant changes in TSS or pH levels compared to the controls. Notably, mushrooms stored in PP bags having nitrogen and stored in the refrigerator exhibited improved quality over eight days, showing better results in BI, moisture content, and texture.\u0000Res.

The intricacy of the problem requires farmers’ compliance with regenerative agricultural practices that can facilitate the conservation of fragile productive systems while sustaining their productivity. Accordingly, various climate change management strategies have been promoted in Ethiopia. This paper analyzed farmers’ participation in CSA practices and the determinants of adoption in the Oromia region of Ethiopia. The data were collected during the 2020 cropping season from 420 randomly selected farmers in the Arsi (highland) and East Shewa (lowland) zones of the Oromia region. The data was analyzed with descriptive and Logit regression. The results showed that of the total thirteen climate-smart agricultural practices that were assessed, about 6 and 4 were adopted by more than 50% of the farmers in the highland and lowland, respectively. Also, 21.0% and 42.4% of respondents from highland and lowland respectively participated in CSA programs or projects. Moreover, 35.5% and 34.8% of the highland and lowland agroecology farmers respectively adopted some CSA after project participation. In highland agroecology, crop rotation, crop residual management, crop diversification, and intercropping were the mostly used practices, while crop rotation, adjustment of planting time, minimum tillage, and planning of drought-resistant varieties were mostly used by lowland agroecology farmers. Moreover, logistic regression results reveal that CSA adoption is influenced by age, education, gender, family size, credit support, experience, extension support, non-agricultural income, and livestock holding. It was concluded that adoption of CSA was low, and promotion of extension support and CSA participation experiences will facilitate adoption of some CSA practices. More importantly, extension support should focus on CSA practices that were widely used by the farmers.\u0000Res. Agric. Livest. Fish.
