The gastrointestinal parasitic infestation seems to have a substantial economic impact on the entire livestock production industry. Because of the parasites' environmental appropriateness, numerous domestic animals in Bangladesh are particularly susceptible to the infestation; however, the extent to which people are aware of the potential risk factors is debatable. Therefore, the current meta-analysis' objective is to determine the precise understanding of potential risk variables and the impact of climatological variations on five important gastrointestinal parasites: Paramphistomum species, Strongyloides species, Trichuris species, Schistosoma species, and Moneizia species. Four globally recognized databases, including Web of Science, Scopus, PubMed, and Google Scholar were screened to choose the studies published in English language from 2000 to 2020. Finally, 29 studies were selected for further analysis and recorded the maximum prevalence in Paramphistomum species (26%; 95% CI: 19-33), followed by Strongyloides species (9%, 95% CI: 5-12), Trichuris species (10%, 95% CI: 4-17), Schistosoma species (19%, 95% CI: 7-31), and Moneizia species (8%, 95% CI: 5-10); besides the overall prevalence was noted as 15% (95% CI: 11-18). Furthermore, subgroup analysis revealed that parasite infestation was most prevalent in females (21%) and the elderly animal population (14%) and the summer season (26%). To sum up, the current meta-analysis visualized the epidemiological risk factors with the overall incidence of five major parasite infestations in livestock animals in Bangladesh; hence, the government and shareholders may employ it as proof before launching any control programs or improving farmers' awareness.

The impact of farmers’ education is examined with a view to evaluate the actual situation of farmers’ education in Bangladesh. Fifty samples were collected from two sub districts of the Gazipur district in Bangladesh. The selection of the study sites and collection of the samples such as the years of schooling of the farm household head, total income, farm size, number of earners of farm families, family size, years of farming experience of farm household head, number of times extension contacts and rice yield were done purposively. It is cleared from the study that education is necessary for farmers to raise their wealth. Results were derived through regression analysis. The study has also shown that size of family and years of farming experience contributed significantly to the wealth accumulation of farmers.

Lumpy skin disease is explained as a significant cattle disease affecting cattle of many parts of the world. An outbreak was experienced in different parts of Bangladesh including Barishal for the first time in the last quarter of 2019. This investigation was carried out to know the outbreak scenario of the disease in southern part of Bangladesh. A total of 726 cattle were included in this study covering 50 dairy farms of Barishal region from September 2019 to December 2019. Morbidity rate was found 21% (CI: 18-24%) and mortality was 1% (CI: 1-2%) in the outbreak area. Young animals (24%) and pregnant animals (70%) were significantly more susceptible compared to aged animals (17%) and non-pregnant animals (15%), respectively. Moreover, male and crossbred cattle were slightly more prone to the infection in comparison to their counterparts. About 45% of the affected animals showed nodular and remaining 55% had edematous lesions. Almost 90% of the affected animals were treated with NSAID followed by antibiotics, antihistaminic, steroid drugs and antiviral drugs where only 20% of the affected animals were treated by authorized veterinary personnel. This was the first epidemiological investigation in the mentioned outbreak area which may serve as a baseline for LSD research in the location needed for developing effective control strategy.

Bovine and caprine mastitis is a dreadful bacterial disease that drastically lowers milk production, and presently it is spreading as an endemic pathogen throughout the world, including Bangladesh. Moreover, mastitis is the main impediment to Bangladesh’s tremendously rising milk-related industry and general livestock economy. Therefore, the aim of this study is to demonstrate the overall prevalence of clinical and sub-clinical mastitis in both dairy cows and goats. It is the foremost meta-analysis study regarding mastitis prevalence in Bangladesh and the study gathered the articles from the electronic database on the topic bovine and caprine mastitis published between January 2005 and November 2020. Finally, 33 articles were selected for estimating the overall prevalence rate of mastitis in ruminant (cow and goat) via random effect model estimation. Analyzing the result, the study found 43.0% (95% Cl: 37.0 - 50.0%) and 31.0% (95% Cl: 15.0 - 47.0%) prevalence rate in dairy cattle and goat. Statistically, the occurrence rate in Bangladesh is significantly higher than other countries. Although many studies showed the seroprevalence across different districts, this study demonstrates the aggregate incidence rates across Bangladesh as a whole. This paper may also serve as a reference point for the implementation of any control strategy of mastitis in Bangladesh.

Mastitis is considered to be the most devastating condition for the dairy farms of low and medium income countries due to its alarming impact on production and worldwide has been recognized as one of the most economically significant infectious diseases affecting the welfare of dairy animal. Chittagong is one of the dairy intensive regions of Bangladesh but comprehensive epidemiological studies addressing prevalence of and risk factors for subclinical mastitis (SCM) are scant. Therefore we aimed to approximate the prevalence of SCM in dairy cows along with the associated risk factors in dairy cows of Chittagong Metropolitan Area (CMA), Bangladesh. We included 114 cross breed (Holstein × Local) lactating cows, raised at 6 dairy farms in CMA between February to November, 2015 for this study. California Mastitis Test (CMT) was used to assess SCM at animal level. The overall prevalence of mastitis was 34.2% among the tested cows. Floor type, source of replacement cows, history of previous reproductive disorder, stage of lactation and cleanliness of floor was found significantly associated with SCM in univariate analysis. In random effect multiple logistic regression model, cemented floor was found to increase the odds of SCM by 5.03 times than that of brick floor. Similarly, cows with history of reproductive disorders had more risk of having SCM than that of cows without a history of reproductive disorders. Since the SCM is prevalent in the study area, the intervention strategy should focus on causal agent, improved management, frequent monitoring of SCM in milking cows with CMT and use of teat disinfectants; with minimal or no treatment with antimicrobial agents.

Nitrogen fixation resulting from mutual symbiosis of rhizobia and cultivated legume plants is therefore critical to food security as it directly affects agricultural production. Biological Nitrogen Fixation (BNF) can be an important factor in sustainable agriculture.The isolation and identification of different slow growing and fast growing rhizobial strains from the nodules of two leguminous plant species. Symbiotic nitrogen fixing Rhizobium spp. was isolated from (Lablab purpureus and Vigna sinensis). Nodules samples were collected from plants growing in different Districts of Bangladesh and the Glucose-Peptone Agar (GPA), Congo red, Yeast Mannitol Agar (YMA) containing 2% NaCl were employed to make presumptive decisions on the recognition and classification of the isolated bacterial strains. All the isolates were found with poor absorption of dye Congo red and little or no growth on the media of GPA and without altering the pH. Almost all of the isolates exhibit growth on 2% NaCl, poor growth on GPA, thus confirming the rhizobia. After biochemical tests like catalase test and citrate utilization test isolates were confirmed as Rhizobia. The presence of rhizobia on root nodules of leguminous Plant. Not only the leguminous Plant but also the rhizosphere contains rhizobia which help in soil fertilization.

Because of using sulphur free fertilizer, rice crop facing tremendous sulphur (S) deficiency throughout the world as well as in Bangladesh. However, farmers of Bangladesh often overlook the importance of sulphur fertilization on rice yield. Therefore, the present study was conducted to investigate the influence of different levels of sulphur on growth, yield attributes and uptake of N, P, K and S by grain and straw of BRRI dhan41 rice variety. The experiment was laid out in randomized complete block design with three replication and eight treatments including control. The result of the study revealed that the highest plant height, panicle length, filled grain was found in T1 (50% RFD of S) treatment, while the utmost number of effective tiller and straw yield was recorded in T5 (150% RFD of S) treatment. Interestingly, maximum grain yield as well as uptake of N, P, K and S by grain and straw was significantly higher in T6 (175% RFD of S) treatment. The highest grain yield of T6 treatment might be due to maximum nutrient use efficiency. However, in all cases control treatment (T0) gave the worst result. The present study clearly indicates that higher rates (175% of the recommended dose) of S along with other fertilizers may be recommended for better growth and yield of BRRI dhan41 in Bangladesh soil.

Garo people are tribal communities who live in the middle northern part of Bangladesh from time immemorial. The purpose of the research was to identify the reasons, outline, and impact on the relocation of Garo people in the city areas in Bangladesh. Primary data were collected from face-to-face contact through an interview schedule. The findings indicate that poverty, lack of production, unemployment, and security were the main push factors where urban job opportunity, urban life style and social security were pull factors for garo migration. Pattern analysis showed that 69 percent of respondents migrate to the city without a plan. Large farm and family size discourged the unplanned migarion where deteriorate social security influence garo people for unplanned migration. Study also revealed that garo people access to better income, health facility, transportation have increased. In contrast, the involvement of agricultureal activity greatly reduced. Moreover, migrated family maintain their daily requirement for food by purchasing market. Government should take policy for improving the security, income opportunity, and infrastructure for discouraging the unplanned migration from village to town.

Peste des petits ruminant (PPR), considered as goat plague is the most fatal infectious viral disease for small ruminants. This disease is endemic in many parts of the world including Bangladesh causes extensive loss on livestock and economy. This study was conducted to estimate the prevalence of PPR and this is the first meta-analysis on PPR as per authors knowledge in Bangladesh. Articles published during the years 2000 to 2019 on the topic PPR within three electronic databases were used for prevalence estimation by random effect meta-analysis model. A total of 39 articles were finally included in the model for prevalence estimation of goat and sheep. 1589784 goat and 142036 sheep were included in the study for analysis. Analysis showed prevalence of PPR was 15.17% (95% CI: 15.11-15.22) and 9.17% (95% CI: 9.02-9.32), respectively for goat and sheep. As PPR is affecting small ruminants in variable percentage in different districts of Bangladesh, this study estimates the cumulative prevalence of Bangladesh. This study may act as a baseline for taking effective control strategy of PPR in Bangladesh through proper allocation of resources on a priority basis.

Access to land in Bangladesh is governed by the state rule but informal tenure arrangement is existing all over the country. Land productivity differs with the contractual arrangement between landlord and tenant. Inefficiency may arise due to sharecropping which is known as Marshallian inefficiency. This study investigated the productivity the productivity, profitability and efficiency of different tenure arrangement of Boro rice cultivation selecting 120 farmers from Rangpur district of Bangladesh. The stochastic frontier production function was employed to determine the efficiency. Moreover, t-test was performed to see whether any significant difference exist among tenure categories in terms of productivity, profitability and efficiency. Four types of tenure arrangements were identified as cash tenant, fifty-fifty input-output sharing arrangement, only output sharing arrangement and owner farmers. Result revealed that productivity and profitability was higher for owner and cash tenant compared to others. Significant productivity and profitability difference were found between owner farmers and cash tenants versus sharecroppers. Result also found that inefficiency level was significantly high for fifty-fifty input-output share tenant and only output share tenant compared to cash tenant and owner operator implying that Marshallian inefficiency exist due to sharecropping system in the Boro rice production.
