Maize genetic diversity is utmost to develop new varieties conferred with favorable agronomic traits. Landraces are priceless resources that can serve to strengthen crop breeding programs. Hence, this study aimed to characterize 19 Sri Lankan maize landraces and one elite commercial variety Bhadra using SSR markers linked with insect-resistant traits. Using established procedures, genomic DNA extraction was done from immature maize leaves and PCR was performed utilizing bnlg1017, bnlg339, umc1021, umc1187, bnlg1346, bnlg1588, bnlg1556, umc1178, nc134, umc1688 and umc1045 primers. GenAlex and DARwin software were used for the data analysis. According to the results, a sum of 77 alleles was amplified with the maximum number of observed (13) and effective (11.28) alleles for bnlg1588. The highest gene diversity and PIC values were recorded in bnlg1588 (0.911 and 0.904 respectively), while the lowest was in umc1045 (0.640 and 0.581 respectively). Out of the total SSR primers used, bnlg1588, bnlg339, bnlg1346, and bnlg1017 linked with FAW-resistant traits were found to be more informative based on their genetic diversity parameters. The accessions SEU7, SEU11, SEU16, and SEU20 showed more genetic diversity compared to Bhadra, whereas SEU17 showed the lowest diversity. The dendrogram divided the 20 maize accessions into two main clusters with the mean similarity of 0.752. Similarly, the principle coordinate analysis explained 40.63 % of the genetic variation and grouped the maize accessions into two. Considering the genetic diversity parameters, the accessions SEU6 and SEU7 from cluster I and SEU9, SEU11, SEU16, and SEU20 from cluster II could be utilized for strategic maize breeding programs in Sri Lanka.

Natural slope protection is challenging all over the country. The study assessed the application of newly designed porous concrete block over conventional concrete block in slope protection. In the study, four different types of concrete blocks were designed; three of them were 8″×8″×3″ and one was 9″×9″×3″ in size. One 8″×8″×3″ porous concrete block design was selected based on it’s compressive strength. Another conventional concrete block of same size was selected for comparing the results. After preparation, the porous and conventional concrete blocks were placed on the slope of a selected earthen canal in a 3-row and 11-column format. According to the findings, the porous concrete block was vegetative while the conventional concrete block was not. The porous concrete block required less volume of materials, which reduced the cost by 18.2% over the conventional concrete block. It is concluded that the newly designed porous concrete block is more cost-effective, light-weight, and vegetative-compatible than the conventional concrete block of the same size. Therefore, the study suggests applying the newly designed porous concrete block to protect the natural slope.

This study investigated the clinical and hematological responses of plasma transfusion and hematinic administration in severely anemic goats. The blood profile of the recipient goats were assessed for hematological: Total Erythrocyte Count (TEC), Total Leukocyte Count (TLC), Hemoglobin (Hb), Packed Cell Volume (PCV), Neutrophil, Eosinophil, Lymphocyte, Monocyte, and Electrolytes and Biochemical parameters: Alanine Transaminase (ALT), Aspartate Transaminase (AST), Creatinine and Total Protein (TP) before and after (1st, 7th, 14th, 21th, 28th days) treatment with plasma transfusion or hematinic administration. In plasma transfusion group (Group A), TEC, PCV, Hb, ALT, AST and TP were increased significantly (p < 0.01) at 1st, 7th, 14th, 21th, 28th days of post-transfusion in comparison to pre-transfusion values. In the hematinic group (Group B), two patients died treated with hematinic. However, no significant changes (p > 0.05) in clinical parameters, electrolytes (K+, Na+ and Cl−) levels and creatinine values were observed in recipient goats after plasma transfusion and hematinic administration. After 28 days of treatment, all patients of plasma transfusion group (100%) and three in hematinic treatment group (60%) were recovered successfully. The plasma transfusion was found superior to hematinic administration to upgrade the hematological and biochemical parameters in anemic goats. It did not produce any adverse reaction in the recipient goats. Plasma transfusion could be an effective tool for the clinical management of anemic goats.

The paramount means of sustaining crop management is a "healthy" soil. This implies that a healthy soil will produce healthy crop that have optimum vigor and are less susceptible to pests. This necessitated the conduct of this study, which examined the adoption of innovative extension advisory service on management of problematic soil (acidic soil). Multi-stage sampling techniques was used to select 180 project farmers; primary data were elicited from the respondents with interview schedule from June to July 2021. Data were analysed using descriptive statistics and factor analysis. The results how that mean age was 44 years and average household size of 14 persons. Majority (97.2%) were married while about 65% had no formal education. The most extension advisory services adopted by maize farmers for management of problematic soil were agric, lime and NPK with the mean value of (X ̅=4.0), application of agric. lime 3 weeks before planting with the mean value of (X ̅=3.9) ranked first and second respectively while for soybean spacing 5cm by 75cm (X ̅=3.9) was mostly adopted. The major problem faced by the respondent in the study area in terms of innovation adoption was low income level of the respondents which was economic factors with the agein value .739 and banditry attacked with agein value of .611 which was cultural factors. The study recommended that OCP Africa should be encouraged by the project coordinators to establish one of their One Stop Shop across the study areas to enhance the utilization of this innovation.

The study aimed to evaluate the seasonal dynamics ingross biochemical compositions of Asiatic hard clam (Meretrix meretrix) collectedmonthly from the west coast ofCox's Bazar, Bangladesh fromJuly2018 to June 2019. The proportion of crude protein, crude lipids, carbohydrates, ash, crude fiber and moisture contents of the clam varied from 10.81 to 15.56%, 0.45 to 3.99%, 0.26 to 5.88%, 0.88 to 2.85%, 0.26 to 1.96% and 72.63 to 82.70% respectively on wet weight basis. Biochemical analysis revealed remarkable temporal variations in the percentage of biochemical components of the species. Pearson’s product-moment correlation coefficient indicated that water quality parameters (temperature, salinity and pH) and biochemical compositions of M. meretrix had different levels of correlations among themselves.Protein and fiber contents were moderately positively correlated with pH (r = 0.515 and 0.495 respectively) but moisture content was moderately negatively correlated with pH (r = -0.484). Protein exhibited strongpositive correlation with ash content (r = 0.856) and strong negative correlation with carbohydrates (r = -0.800). Moderate positive correlation was found between protein and lipid (r = 0.596). Protein, lipid, ash and fiber contents had moderate negative correlations with moisture content (r = -0.542, -0.641, -0.503 and -0.423 respectively). Overall, the study revealedthat Asian hard clam is an excellent source of several nutrients and the information furnished could be useful to the fishery managers for harvesting and marketing of M. meretrix in a particular season of the year based on the consumers’ specifications.

The rural women of Bangladesh are getting involved in different income-generating activities like fish processing. Through these activities, rural women contribute to the family income and ensure a better life for the family members. In this perspective, the current study was conducted to assess the livelihood changes of the rural women working in the fish processing plant, identifying the factors affecting the livelihood change and finding out the problems faced by the rural women worker while working in the fish processing industry. The study was conducted in the Trishal Upazila of Mymensingh district. The population size was 140; out of them, 70 were selected randomly. A pre-tested questionnaire was used to collect data through a face-to-face interview. Then, regression analysis was done to identify associated factors. The majority (68%) had a medium change in livelihood. Household size, annual family income, training, and extension media contact were the most crucial variables explaining the respondents' livelihood change. Moreover, most (60%) of the women faced low problems in fish processing activities. Among the identified problems, the major concerns were lack of technical knowledge, transportation facility, and poor salary. Therefore, government and non-government organizations must provide frequent need-based training facilities for rural women to strengthen their skills that may help improve their livelihood.

This study elucidates the present scenario of poultry litter management practices and development of a technique for safe management of litter at farmer’s level. Survey-based data were collected through pre-tested questionnaires from some purposively selected 42 poultry farms erected within the areas of Mymensingh, Gazipur, Netrokona, and Jamalpur districts. A large amount of poultry litters were generated from broiler and layer farms daily. Most of the farmers dumped this litters in open places (50%) which caused a serious environmental and health hazards. A self-aerated composting technique was designed and developed to effectively manage and mitigate the environmental and health hazards evolving from poultry litters. A compost heap was prepared with rice straw, water hyacinth, and poultry litters with the proportion 1:2:4 respectively by weight at the optimum C:N ratio of 30:1 incorporating the provision for air entraining into the bulk compost heap. Temperature and moisture contents at time interval of three days, and pH, C/N ratio, volume, and microbial properties at time interval of seven days were observed throughout the composting period of 60 days. Analysis was accomplished taking representative samples from the compost heap using the random sampling technique. The quality of compost in terms of nitrogen, phosphorus, potassium, and organic carbon was evaluated in accordance with the Indian and Australian Standards. This technique is found environmentally safe, functional and cost-effective. The developed self-aerated composting technique would be an alternative option for safe management of poultry litters for the farmers in the rural areas.

Lumpy Skin Disease (LSD), a contagious viral disease, had been a matter of great concern for Bangladesh as the outbreak of LSD occurred in the mid of 2019. Later the disease began to show symptoms like significant production loss, infertility, aberrant pregnancies and abortions, and even fatalities. So, a retrospective study was carried out to investigate the prevalence rate and associated risk factors of LSD in cattle at Barishal district, Bangladesh. The study was performed at Upazilla Veterinary Hospital, Babuganj, Barishal from January 2021 to June 2022. Among 2047 clinical cases reported at the hospitals, 44 cases were found as LSD positive. The prevalence rate of LSD in the aforementioned territory was 2.15%. The highest prevalence was estimated in June 2022 (13.39%) followed by May 2022 (7.32%), August 2021(4.35%), February 2021(4.00%), April 2022 (2.23%), March 2021 (1.69%), February 2022 (1.53%), March 2022(0.76%), September 2021 (0.75%). In the contrast, no LSD case was detected in Jan 2021, May 2021, Jun 2021, Oct 2021, Nov 2021, Dec 2021, and Jan 2022. Breed [χ2 (1, N=2047) =4.989, p<.05] and sex [χ2 (1, N=2047) =4.695, p<.05] of the animals were identified as significant demographic factors for LSDV infections in this locality. Additionally, indigenous breeds [(2.63%), 95%CI: 2.454 (1.088-5.534)], females [(2.76%), 95%CI: 0.484 (0.248-0.946)] and older cattle (>5 years) (3.48%) had a greater prevalence rate than the crossbreeds, males and younger cattle respectively. As LSD has recently become more prevalent, restriction of animal movements, control of vectors, proper vaccination and treatments, routine-wise animal screening, immediate isolation and quarantine of the affected animals are some of the strategies that are strongly recommended and might be followed for reducing the LSD occurrence and spreading in this area.
{"title":"Demographic factors influencing Lumpy Skin Disease (LSD) prevalence at Barishal district in Bangladesh: A retrospective study","authors":"A. Sayed, M. Hossain, S. Akter, M. Rashid","doi":"10.5455/jbau.135650","DOIUrl":"https://doi.org/10.5455/jbau.135650","url":null,"abstract":"Lumpy Skin Disease (LSD), a contagious viral disease, had been a matter of great concern for Bangladesh as the outbreak of LSD occurred in the mid of 2019. Later the disease began to show symptoms like significant production loss, infertility, aberrant pregnancies and abortions, and even fatalities. So, a retrospective study was carried out to investigate the prevalence rate and associated risk factors of LSD in cattle at Barishal district, Bangladesh. The study was performed at Upazilla Veterinary Hospital, Babuganj, Barishal from January 2021 to June 2022. Among 2047 clinical cases reported at the hospitals, 44 cases were found as LSD positive. The prevalence rate of LSD in the aforementioned territory was 2.15%. The highest prevalence was estimated in June 2022 (13.39%) followed by May 2022 (7.32%), August 2021(4.35%), February 2021(4.00%), April 2022 (2.23%), March 2021 (1.69%), February 2022 (1.53%), March 2022(0.76%), September 2021 (0.75%). In the contrast, no LSD case was detected in Jan 2021, May 2021, Jun 2021, Oct 2021, Nov 2021, Dec 2021, and Jan 2022. Breed [χ2 (1, N=2047) =4.989, p<.05] and sex [χ2 (1, N=2047) =4.695, p<.05] of the animals were identified as significant demographic factors for LSDV infections in this locality.
