Seroprevalence and pathology of Mycoplasma gallisepticum infection in layer birds

Avian mycoplasmosis, caused by Mycoplasma gallisepticum (MG), imposes a significant threat to the poultry industry in Bangladesh, leading to considerable economic losses. This study aimed to determine the seroprevalence of MG and characterize the associated pathology in MG-infected layer birds from different geographical areas within the Nilphamari district. Our hypothesis suggested that the seroprevalence of MG infection in layer birds may vary based on geographical location within the Nilphamari district of Bangladesh, with higher prevalence expected in areas with colder temperatures, such as during the winter season, and in densely populated poultry farming regions. For the serum plate agglutination test, 400 random blood samples were collected, while tissue samples from suspected layer birds with respiratory distress were obtained from 40 commercial layer farms for histopathological analysis. The serum plate agglutination test revealed an overall seroprevalence of MG of 64.25%, with the highest prevalence occurring during the winter season (70%), particularly among layer birds aged 20-40 weeks. Moreover, the seroprevalence of MG was significantly higher in Kishoregonj upazila (68%) compared to Nilphamari sadar (62%). Gross examination of MG-infected layer birds unveiled characteristic features such as tracheal hemorrhages and mucous accumulation, pulmonary edema and hemorrhages, and air sac cloudiness. Histopathological observations included tracheal mucosal sloughing and increased goblet cell numbers, as well as lung edema, hemorrhages, and tissue destruction, alongside significant reactive cell infiltration and exudation in the air sacs. By shedding light on the current MG infection status in layer chickens within the Nilphamari district, this study provides valuable insights to aid poultry industry stakeholders in formulating preventive strategies and enhancing the overall health and welfare of poultry flocks.

Morphological and phylogenetic analysis of Raillietina spp. in indigenous chickens (Gallus gallus domesticus) in Bangladesh

Raillietina spp. (Cestoda: Davaineidae), the most common cestodes in indigenous chickens, cause a substantial production loss in poultry industry in Bangladesh. Here, we estimated the prevalence, confirmed the species and determined the genetic pattern of species of Raillietina using molecular tools. We collected and examined 375 chickens randomly from household of different villages of Mymensingh sadar and Gouripur upazila, Mymensingh district and adult parasites were isolated and identified. Genomic DNA was extracted from collected parasites, amplified ITS-2 and ND-1 genes, sequenced and analyzed. Out of 375 samples, 270 (72.0%) were found positive with Raillietina species and mean worm burden was 10.46 ± 0.56. Microscopically, three species of Raillietina, such as R. cesticillus (37.9%), R. echinobothrida (41.1%) and R. tetragona (52.8%) were detected on the basis of their morphological features. The total length, length and width of scolex, sucker and rostellum were also measured. Among different factors, age, farming nature and flock size of chickens were significantly (p < 0.05) influenced Raillietina infections. For further validation, the sequences of ITS-2 gene generated in this study were matched with reference sequences of R. cesticillus, R. echinobothrida and R. tetragona and found 99.63% − 100% similarity. The phylogenetic analyses of ITS-2 and ND-1 sequences were clustered together with the reference sequences of R. cesticillus, R. echinobothrida and R. tetragona confirming microscopic identification. This is the first confirmation of species of Raillietina along with the prevalence of the species, which will be helpful for the formulation of a control strategy and provide basic information for further molecular study.

Seroprevalence of Salmonella spp. infection in different types of poultry and biosecurity measures associated with Salmonellosis

Salmonella spp. infection is considered a crucial trouble of the poultry industry in Bangladesh. Hence, this study was aimed to estimate the seroprevalence of Salmonella spp. in poultry along with biosecurity practices that are associated with this Salmonella spp. infection. The study was conducted during the period from January to September, 2021 in Mymensingh and Gazipur district of Bangladesh. A total of 314 samples were considered to determine the seroprevalence. Seroprevalence was determined by performing the rapid serum plate agglutination test. The result revealed that the overall Salmonella spp. seroprevalence was 47.77% in the study area. The higher seroprevalence was in Mymensingh (51.59%) than Gazipur (45.21%) without significant (p&amp;gt;0.05) difference. The highest seroprevalence was in broiler (51.33%) where in layer and sonali was 32.67% and 16% respectively. Seroprevalence was significantly (p&amp;lt;0.05) higher in summer for layer (56.45%), broiler (60.64%) and sonali (51.22%) than the winter seasons. In layer farms, the flock size of &amp;gt;2000 to &amp;lt;2500 had significantly (p&amp;lt;0.05) higher (71.43%) seroprevalence. In broiler farms, 15 to 30 days old birds had significantly (p&amp;lt;0.01) higher (77.05%) seroprevalence than other age. Among the different categorical level of biosecurity practices, the poultry farms that used surface water (OR=0.182, 95% CI=0.106-0.314); disinfectant regularly (OR=0.296, 95% CI=0.171-0.511); having density of 8-10 birds/meter2 (OR=0.379, 95% CI=0.219-0.654); cleaned waterer and feeder regularly (OR=0.503, 95% CI=0.294-0.862); and having visitor restriction (OR=0.375, 95% CI=0.219-0.643) showed lower tendency (p&amp;lt;0.001) to seroprevalence. In brief, Strict farm hygienic practice and biosecurity measures are significantly linked to decrease the Salmonella spp. seroprevalence.

Assessment of Biosecurity Status of Broiler Farm at Jamalpur District.

Broiler chicken production is an important source of animal protein supply, but the biosecurity conditions of Jamalpur region are not satisfactory. This study was done to gauge farmers' knowledge of and adherence to biosecurity guidelines of a broiler farm. We visited five randomly selected farms in two unions of Jamalpur district. The questionnaires were developed based on “biosecurity guideline for commercial poultry industry in Bangladesh”, provided by the department of livestock services of Bangladesh. There were 143 parameters, and each one of them bears 1 point. For each parameter that a farm followed, it gained one (1) point. The parameters were divided into 5 different principles: isolation, good farm hygiene, flock health care and monitoring, good farm management practices, and compliance with government regulations. Farm hygiene and compliance with government regulations were most commonly ignored principle by all the farms, especially in case of farm worker’s hygiene All the farm had trees adjacent to the shed. The highest score was 62 (43.37%), gained by Farm 2, and the lowest point was 37 (25.87%) gained by Farm 1. The average score was 50 (34.97) points. This is the first survey work in this region, but there were difficulties in working with a larger number of farms due to the COVID-19 pandemic with frequent lockdowns. This study may help to improve the biosecurity conditions of broiler chicken production in small stockholders of this region.

A Case of Newcastle disease from an outbreak in a commercial broiler farm in Mymensingh city, Bangladesh

Background Newcastle disease (ND) is a contagious and often deadly viral disease caused by the Newcastle disease virus (NDV), affecting a wide variety of domestic and wild birds. The outbreak of this fatal disease is one of the greatest constraints to the expansion of poultry farms, resulting in significant financial losses. Here we report the clinical and pathological features of a ND case from an outbreak in a commercial broiler farm. Materials and Methods A broiler farm with a population of 850 birds aged 27 days reported the death of 100 chickens within 4 days of the onset of the disease in 2019. For investigation, one dead chicken was brought to the department of pathology, Bangladesh Agricultural University, Mymensingh. The case history was recorded, and an autopsy was performed. Portion of the samples were kept in 10% neutral buffered formalin for histopathological study. Results The morbidity and mortality rates were reported to be 17.65% and 11.47%, respectively. Recorded clinical history were depression, off-feed, huddling, gasping, ruffled feathers, greenish diarrhea, soiled vent and the birds were unvaccinated. On external examination, the birds appeared dehydrated, dyspneic and had nasal exudates, ruffled feathers, and soiled vents. Autopsy exhibited prominent gross lesions in the trachea, lungs, proventriculus, gizzard, intestine, cecal tonsil, liver, spleen and cloacal bursa. Grossly, tracheal hemorrhage, severe congestion in the lungs, pin point hemorrhages on the tip of the proventriculur glands, hemorrhage in the cecal tonsil, button-like ulceration in the intestine and mottled spleen were suggestive of ND. Histopathologically, severe enteritis, necrotic mass in the cecal tonsil and proventriculus, lymphoid depletion in the spleen supported the infection of NDV. The clinicopathological findings of the ND outbreak in broiler farm confirmed that it was velogenic viscerotropic in nature. Conclusion ND in commercial flocks remains a threat to the poultry industry in Bangladesh. Implementation of strict biosecurity, husbandry practice and effective vaccination are required to prevent diseases and improve economic stability.

Antibiotic Susceptibility Pattern and Identification of Multidrug Resistant Novel &amp;lt;i&amp;gt;Salmonella&amp;lt;/i&amp;gt; Strain in Poultry Chickens of Hathazari Region in Chattogram, Bangladesh

Poultry chickens are potential source of transmission of zoonotic Salmonella, into human food chain, causing food-borne illness and also hindering development of poultry industry in Bangladesh. The non-judicious uses of antibiotics in poultry farm have increased the multidrug resistant bacteria. So, this study reports the occurrence of Salmonella in poultry samples (meat, egg, liver and cloacal swab) and the antimicrobial resistance pattern of the isolates. This study was carried out throughout the period of May 2019-March 2020, at the bacteriological laboratory in the Department of Microbiology, University of Chittagong. Isolates were identified on the basis of cultural and biochemical tests from a total of 25 broiler samples (meat, liver, eggshell and cloacal swab). Antibiotic susceptibility pattern was observed using Kirby-Bauer disk diffusion method. The overall detection rate of Salmonella was 48% (12/25) and the highest occurrence was noticed in raw meat 62.5% and the lowest in liver (37.5%). The antimicrobial resistance tests revealed that all the isolates (n = 12) exhibited 100% resistance to vancomycin and cephalexin, followed by ampicillin (75%), nalidixic acid (58.33%), chloramphenicol (41.66%), doxycycline (50%), and neomycin (50%). On the other hand, ciprofloxacin showed 83.33%, ceftazidime and amoxicillin showed 91.6% sensitivity respectively. A considerably high proportion of isolates (11/12, 91.67%) was resistant to three or more antibiotics and 6 multidrug profiles were observed. The ampicillin-chloramphenicol-nalidixic acid-neomycin-cephalexin-doxycycline-vancomycin (4/12) was more frequently observed phenotype in multidrug profiles. Finally, two multidrug-resistant strains of Salmonella were identified and classified based on their 16S ribosomal RNA gene sequences as Salmonella enterica subsp. enterica strain Eshaa2 and Salmonella enterica subsp. enterica strain Eshiika3 at NCBI GenBank with Accession no. MT163513 and MT164531 respectively. So, more attention should be focused on increasing antibiotic surveillance to cope with the spread of emerging resistance and on the alternative approaches.

Seroprevalence and associated risk factors of mycoplasmosis in layer chickens at southern region of Bangladesh

Mycoplasma gallisepticum (MG) is the most important pathogenic Mycoplasma spp. causing avian mycoplasmosis and brought about huge economic losses to poultry industry in Bangladesh. The present study was undertaken to know the seroprevalence of MG in layer birds in three different geographical areas of southern Barishal division, Bangladesh. Total 310 sera samples were collected from wing vein of 30 farms for this study. Sera samples were tested with Rapid Serum Agglutination (RSA) for MG using commercial Antigen Kit (manufactured by Lillidale Diagnostic) to detect the presence of antibodies against MG. The overall seroprevalence of MG by RSA was 36.13%. Seroprevalence of MG infection was dominant in winter season (45.54%) and significantly highest occurrence was recorded in age groups from 20-40 weeks of layer chickens (51.79%). Serological investigation in three different upazila of Barishal division showed the highest infection rate (45.26%) in medium scale flocks (1000-3000) in comparison to (21.43%) small (&lt;1000) flocks. The seroprevalence of MG was highest in Swarupkathi (44.38%) than in Barishal Sadar (26%) and Banaripara upazila (28%). Biosecurity and managemental failure is the overall risk factor in all types of farm due to lack of proper knowledge among farmer. This study reveals the current scenario of mycoplasmosis in layer birds of three different areas of Barishal division. Asian J. Med. Biol. Res. 2021, 7 (3), 292-297

COVID-19 Impact on Poultry Production and Distribution Networks in Bangladesh

The COVID-19 pandemic has severely affected numerous economic sectors across the world, including livestock production. This study investigates how the pandemic has impacted the poultry production and distribution network (PDN), analyses stakeholders' changing circumstances, and provides recommendations for rapid and long-term resilience. This is based on a literature review, social media monitoring, and key informant interviews (n = 36) from across the poultry sector in Bangladesh. These included key informants from breeder farms and hatcheries, pharmaceutical suppliers, feed companies, dealers, farmers, middlemen, and vendors. We show that the poultry sector was damaged by the COVID-19 pandemic, partly as a result of the lockdown and also by rumors that poultry and their products could transmit the disease. This research shows that hardly any stakeholder escaped hardship. Disrupted production and transportation, declining consumer demand and volatile markets brought huge financial difficulties, even leading to the permanent closure of many farms. We show that the extent of the damage experienced during the first months of COVID-19 was a consequence of how interconnected stakeholders and businesses are across the poultry sector. For example, a shift in consumer demand in live bird markets has ripple effects that impact the price of goods and puts pressure on traders, middlemen, farmers, and input suppliers alike. We show how this interconnectedness across all levels of the poultry industry in Bangladesh makes it fragile and that this fragility is not a consequence of COVID-19 but has been revealed by it. This warrants long-term consideration beyond the immediate concerns surrounding the COVID-19 pandemic.

Multilocus sequence typing of multidrug-resistant Salmonella strains circulating in poultry farms of Bangladesh.

Salmonella is one of the most important foodborne zoonotic pathogens, and becoming multidrug-resistant (MDR), which represents a serious public health concern worldwide. This study aimed to identify the circulating MDR strains of Salmonella through cutting edge molecular techniques including gene specific PCR, RAPD-PCR, ribosomal gene sequencing, and multilocus sequence types (MLST) in the poultry industry of Bangladesh. Two hundred Salmonella isolates were retrieved from 154 samples comprising droppings (n = 60), cloacal swabs (n = 60), feeds (n = 14), feeding water (n = 14), and handler's swab (n = 6) from 14 commercial layer farms of Bangladesh. The isolates were confirmed as Salmonella through invA gene specific PCR, and further genotyping was done by RAPD-PCR, and 16S rRNA sequencing. The isolates were distributed into 18 different genotypes according to RAPD typing. The phylogenetic analysis identified three diverging phylogroups such as S. enterica Litchfield, S. enterica Enteritidis and S. enterica Kentucky with 11, 8, and 6 strains, respectively. The in vitro antibiogram profiling the Salmonella isolates through disc diffusion method using 13 commercially available antibiotics revealed highest resistance against doxycycline (91.5%) followed by tetracycline and ampicillin (86.0%, in each), and 72.0% isolates as MDR, being resistant to ≥ 5 antibiotics. The MLST typing was carried out based on the PCR amplification of seven housekeeping genes (aroC, hisD, hemD, purE, secA, thrA, and dnaN). MLST typing also revealed three sequence types (STs) such as ST11, ST198, and ST214 in these isolates, and eBURST analysis showed ST11 as the founder genotype. The three STs were highly resistant to tetracyclines and quinolone group of antibiotics, and all of the isolates harboring S. enterica Litchfield showed the highest resistance. Circulating common MLSTs with MDR properties in different farms confirmed the possibility of a common route of intra-farm transmission. We report for the first time of the association serovar Litchfield (ST11) in avian salmonellosis with MDR properties which is an urgent public health concern in Bangladesh.

How Contract Farming in Poultry Industry Contribute to the Sustainable Community Economic Development of Bangladesh: A Literature Review

In agricultural production, contract farming is a widely recognized strategy all over the world where similar type of farmers from different corners of a country are engaging under a single industry. In poultry industry of Bangladesh, Contract Farming (CF) is quite popular. Since inception in 1994, contract farming in poultry industry is quite common and major industrial players of Bangladesh deploy this strategy for gaining competitive advantage. In the CF model, the contribution of an individual farmer to the gigantic production volume of a large poultry farm can’t be denied and, in this way,CF can play a vital role in the sustainable community economic development. The objective of the study is to assess how Contract Farming can contribute in the sustainable community economic development of Bangladesh in the light ofSustainable Development Goals. The study is literature review in nature and secondary sources of information has been consulted. The study concluded that, contract farming is crucial in poultry industry and its contribution in assuring sustainable community economic development is significant.

Serological detection of avian reovirus in different poultry flocks of Gazipur and Mymensingh districts of Bangladesh.

Background and Aim:Avian reovirus (ARV) is a constraint to poultry industry in Bangladesh as a cause of several diseases in chickens, especially in broiler. However, the actual status of the viral infection is not known because the large-scale study is not conducted in this country. Therefore, this study aimed to check the presence and distribution of ARV-specific antibody in respect to area, types of chickens (broiler breeder, broiler, and layer), vaccination status, and age of chickens in Gazipur and Mymensingh districts of Bangladesh.Materials and Methods:A total of 276 chickens’ blood samples were collected from two well-organized broiler breeder stock, seven broiler farms, and five layer farms located at two districts, namely Gazipur and Mymensingh of Bangladesh. Blood samples were collected from wing vein of the apparently healthy chickens using 3 ml of syringe and serum was harvested by keeping the syringe at room temperature in slanting position. The sera were transferred to the laboratory by maintaining the cool chain and further processing was performed by indirect enzyme-linked immunosorbent assay using ARV antibody test kit.Results:The results of serological test revealed that an average of 39.5% seropositive against ARV was recorded in chickens of Gazipur and Mymensingh districts. Among these, chickens of Gazipur district had the highest seropositivity of 50.5% than Mymensingh (30.7%). With respect to vaccination status, the seropositivity of vaccinated chickens in both areas was 100% and non-vaccinated chickens was 50.5% in Gazipur and 30.7% in Mymensingh district, respectively. However, regarding age groups, the seropositivity was higher in the age of 4-6 weeks (64.5%).Conclusion:The present serological findings showed a higher prevalence of ARV-specific antibodies in broiler birds. It indicates that the poultry industries of Bangladesh are contaminated with ARV which may naturally be transmitted to chickens either vertically or horizontally.

Seroprevalence of Salmonella Infection in Commercial Layer Chickens in Cox’s Bazar District, Bangladesh

Salmonellosis is a zoonotic disease, usually transmitted from animal to human and vice versa and causes huge economic losses in poultry industry of Bangladesh. This study was aimed to estimate the seroprevalence of Salmonella infection in commercial layer farms of Cox’s Bazar district of Bangladesh, during the period from February to April, 2016. A total of 200 blood samples were collected from 20 farms of 4 randomly selected upazillas of Cox’s Bazar considering the age groups, and flock sizes. Rapid serum plate agglutination test was done and 42% chickens were found positive for Salmonella infection. With respect to age groups, the seroprevalence was higher (68%) in adults compared to young (20%) chickens. However, the seroprevalence of Salmonella infection was recorded remarkably (54.28%) in large flocks compared to small flocks. In conclusion, we can say that, Salmonella infection is prevalent in the commercial layer chickens of Cox’s Bazar district, Bangladesh. Appropriate measures and strategies should be taken for successful prevention and control of this disease in Bangladesh.

Occurrence of Multidrug Resistant Salmonella spp. in Poultry and Approach for Its Indigenous Bio-control

A significant limitation to flourish poultry industry in Bangladesh is the emergence of multidrug resistance pathogenic bacteria like Salmonella spp. due to uncontrolled use of antibiotics for disease treatment. An alternative to antibiotics could be the application of probiotics. About 120 cloacal-swabs from poultry birds were investigated, seventy two (72) isolates of Salmonella spp. and twenty two (22) isolates of lactic acid bacteria (out of 50)were identified respectively by cultural, morphological and biochemical tests presumptively. Antibiotic sensitivity test of Salmonella spp. was performed, followed by Kirby-Bauer disc-diffusion assay with six antibiotic groups. All those isolates of Salmonella spp. were found to be highly resistant to â-lactam, cephalosporin, tetracycline and macrolide, highly sensitive to carbapenem and moderately sensitive to aminoglycosides. Then Salmonella spp. were used as a target for the prospective probiotic bacteria which were screened based on antimicrobial activity against those multidrug resistance Salmonella spp. In antagonism assay such as disc diffusion and one-streak method, it was revealed that five lactic acid bacteria showed antimicrobial activity against Salmonella spp. Further, lactic acid bacteria were characterized based on their tolerance ability to pH and NaCl, antibiotic susceptibility test. The tolerance range of Lactic acid bacteria was about pH (3.5-9.5), NaCl (4-8) % and also resistant to antibiotics groups like B lactam, aminoglycosides, and quinolone. Then 16S rDNA gene sequence analysis was performed for molecular identification of potential probiotic bacteria. One representative isolate was identified as phylogenetically closed relative to Pediococcus acidilactici. This study was able to demonstrate that Pediococcus acidilactici as anindigenous probiotic candidate to inhibit the growth of isolated multidrug resistant Salmonella spp. in poultry. The potent probiotic candidate Pediococcus sp. could be used to counter bacterial diseases in poultry, thereby it could ensure food safety in the poultry industries of Bangladesh.&#x0D; Bangladesh J Microbiol, Volume 34 Number 2 December 2017, pp 83-90

Alkali Enzymatic Extraction of Keratin Protein from Chicken Feather Waste in Bangladesh

Keratin is a highly specialized fibrous protein, which is found in feathers, hair, wool and nails. Bioremediation of these waste materials is an issue requiring serious attention regarding environmental concern. In the present research work keratin protein is extracted from poultry chicken feather which is now treated as valueless product of poultry processing plants. Although it contains high keratin protein content, this byproduct is dumped continuously into the environment without further treatment. Millions of tons of chicken feathers are produced every year from poultry industry of Bangladesh which disposed off into environment without any industrial treatment. This protein rich valuable byproduct can be recycled and utilized effectively which has great economic and ecological importance. In this study, alkali-enzymatic hydrolysis was done for the extraction of keratin protein from feather. Desired result was found in reflux condensation system which yielded 76.2% protein hydrolysate compared to conventional hot plate hydrolysis which was yielded 52.63%. Detection and concentration of protein were determined by Biuret and Kjeldahl methods respectively.

The Seroprevalence Study of Reticuloendotheliosis Virus Infection in Chicken in Bangladesh

We showed seroprevalence of Reticuloendotheliosis virus (REV) in poultry in selected areas of Bangladesh.Total 3,555 serum samples were collected between 2014 and 2016 from 10 districts, 6 types of chicken and 144 flocks, tested for the specific antibodies directed against REV by indirect Enzyme Linked Immunosorbent Assay (ELISA). The overall seroprevalence of REV in the chickens tested were 21.13% (751/3,555) and 73.61% (106/144) flocks were seropositive. According to district, Gazipur had the highest (49.50%) and Khulna had the lowest (9.09%) seropositive rates.Additionally, the prevalence rates were highest 38.21% during onset of laying period, age between 19 and 24 weeks. The positivity rates were almost same round the year like 22.96% in summer, 20.70% in rainy and 20.43% in winter seasons.Furthermore, the seropositive rates in broiler flocks, broiler breeder flocks, commercial layer flocks, layer breeder flocks, sonali flocks, and domestic chicken flocks were 6.86%, 42.15%, 25.84%, 33.59%, 9.40%, and 6.49%, respectively. Conclusion: These results indicate that REV infections are widespread ubiquitous in all types of chickens and may appear as a potential threat for the rapidly growing poultry industry in Bangladesh. This is the first seroprevalencestudy on REV infections in chicken in Bangladesh.More prevalence study, molecular characterization and vaccine production from local isolates are emergency requirements to combat REV. The quality verification of imported vaccine must be strongly adopted.

RISK ASSESSMENT OF CHROMIUM LEVELS IN BROILER FEEDS AND MEATS FROM SELECTED FARMS OF BANGLADESH

The present study was conducted to evaluate the status of chromium concentration in broiler feeds with the risk assessment of chromium in broiler meat. Seven broiler farms were selected to collect the feed and meat samples of broiler. Atomic absorption spectrophotometer (AAS) was used to determine the chromium concentration in broiler feed and meat samples. The highest concentration of chromium in broiler meat samples was 1.31±0.20 ?g/g and in feed samples was 1.71±0.24?g/g. In this study, the mean (± SE) concentration of chromium in feed samples from Gazipur Sadar, Gazipur; Sreepur, Gazipur and Tangail Sadar, Tangail were 1.71(± 0.24) ?g/g,1.64(±0.61) ?g/g and 1.64(±0.61) ?g/g respectively. The mean (± SE) concentration of chromium in meat samples from Gazipur Sadar, Gazipur; Sreepur, Gazipur and Tangail Sadar, Tangail were 1.139 (±0.26) ?g/g, 1.31 (±0.20) ?g/g and 0.61 (±0.23) ?g/g respectively. The concentrations of chromium in broiler edible tissues were much higher than permissible levels determined by FAO and WHO. Precocious steps must be taken to avoid use of such health hazardous concentrations of heavy metals in poultry feeds. Considering these findings, there is a critical need to set legal limits and surveillance system for detection of heavy metals in poultry industry of Bangladesh.
