Materials and Methods: The sperm sample was pooled, washed, and diluted in control (TCEF without glucose and trehalose), TCEF + glucose (75, 150, 450, and 900 mm), and TCEF + trehalose (75, 150, 450, and 900 mm). After equilibrations, the semen straws were frozen under LN2 in the LN2 tank. After LN2 storage, the straws were thawed at 37°C for 30 seconds. The sperm parame¬ters of all study groups were checked after equilibration and freezing. Results: After equilibration, the progressive motility (PM), total motility (TM), and viability of sperm in G-75, G-150, G-450, T-75, T-150, and T-450 were not significantly different (p < 0.05) from those in control. After cryopreservation and thawing, the PM, TM, and plasma membrane integrity (PMI) of T-150 were significantly higher (p < 0.05) than in control, G-75, G-900, T-75, and T-900. The viability of sperm in T-150 was substantially higher (p < 0.05) than in the control, whereas there was no significant difference among the control, G-75, G-900, T-75, and T-900. However, the acrosome integrity (AI) of sperm in G-900 was significantly decreased (p < 0.05) compared to the control, G-75, G-150, G-450, T-75, T-150, and T-450. Conclusion: According to the findings, the supplementation of 150 mm trehalose in the TCEF dilu¬ent was more efficient for sperm cryopreservation in the buck as reflected by PM, TM, viability, PMI, and AI.

Materials and Methods: A cross-sectional KAP study was conducted with native poultry keepers and small-scale commercial poultry farmers in seven districts of Bangladesh. In the survey, 385 poultry producers were interviewed using validated structured questionnaires through face-to-face interviews to collect the quantitative data in their domiciles. Results: The overall KAP of farmers regarding poultry waste management issues demonstrated a low level of KAP (p = 0.001). The analysis shows that roughly 5% of farmers have a high level of knowledge of poultry waste management issues, followed by around one-third of respondents having a moderate level of knowledge. Considering the attitude domain, more than one-fifth of native poultry keepers and nearly two-thirds of commercial producers demonstrated a low level of attitude toward poultry waste management. Considering the overall analysis, roughly half of the respondents found a high level of attitude, and over half of the farmers showed a moderate level of attitude toward poultry waste management issues. The analysis showed that the level of good practices for native and commercial poultry production systems is estimated at 77.3% versus 45.9%, respectively, despite the farmers' lesser knowledge and attitudes toward poultry waste management systems. Overall, analysis showed that nearly 60% and 40% of poultry producers had high and moderate levels, respectively, of good practices in poultry waste management issues. Conclusion: Analysis of the KAP data shows that farmers had a low level of KAP toward poultry waste management. The result of this study will assist in formulating appropriate strategies and to adopt poultry waste management solutions by poultry farmers to reduce environmental degradation.

A total of three hundred forty-five one-day-old Ross-308 broiler chicks were randomly allotted into five treatment groups as T1, T2, T3, T4 & T5 (6 hrs, 12 hrs, 24 hrs, 48 hrs, and 60 hrs of post-hatch feed and water deprivation). Birds were allowed a two-phase feeding system, such as starter and finisher, where appropriate. Performance parameters include feed intake (g/birds), body weight gain, average daily gain, feed conversion ratio, and viability% for growth periods (1 d to 7 d, 1 d to 14 d, 1 d to 21 d, 1 d to 28 d) were calculated. All chicks were vaccinated with live attenuated Newcastle Disease Virus LaSota strain on day 2 via eye drop vaccination, along with other basic immunization schemes. After 14 days of ND vaccination, post-vaccination sera samples were collected and subjected to an HI test to determine antibody titers. The Haemagglutination inhibition test was done using Newcastle Disease Virus LaSota strain NLT 106.0 EID50 antigen. Post-hatch feed and water deprivation durations significantly affect the production parameters. Feed intake, body weight gain and average daily gain were significantly (p<0.01) lower in the T5 group. Significantly (p<0.01), a poor feed conversion ratio was observed in the T5 group. The lowest (91.66%) survivability (p<0.01) was found in the T5 group compared to other groups. There was a significant (p<0.01) difference in European Broiler Index for growth periods. Post-hatch feed and water deprivations did not influence (p>0.05) the antibody titer level against the Newcastle disease virus. Increasing post-hatch feed and water deprivation leads to lower feed intake, body weight gains, poor feed conversions, and lesser livability of broilers. Therefore, early access to feed and water after hatching is recommended to achieve better production performance of broilers.

Prolactin is the primary regulator of broodiness. As a result, the goal of our research was to see if lower prolactin levels can limit broodiness, resulting in increased egg production and increased economic value. Sixty indigenous chickens aged 18-20 weeks were divided into three groups of 20 hens each. One was left untreated, two were given GnRH (0.50 ml/bird @ S/C) with Anti-prolactin (Bromocriptine 640 g/bird/day @ orally), and three were given GnRH, Anti-prolactin, and cold therapy (1 time/day) for three months. The chickens were first given GnRH injections once a week for three weeks. It was given on the 13th day of egg production and continued for 10 days. After utilizing GnRH plus anti-prolactin medications for 13 days, the cold application was given every day at the same time. Hormone analysis, egg production, brood...

It has brought about a considerable amount of financial losses to the poultry sector in Bangladesh. We conducted a study on the Seroprevalence of MG infection in two different geographical areas of Bangladesh under Rajshahi district, namely Paba and Bagmaraupazila. 800 sera samples were collected and tested with Rapid Serum Plate Agglutination Test (RSA) to identify the MG antibodies using commercial Mycoplasma gallisepticum antigen. The gross Seroprevalence of MG infection was 59.25% in the study area. The maximum rate (68.80%) of infection was found in the winter season, followed by the summer season (49.36%). The result further revealed that the condition was higher (69.01%) in larger-sized flocks than in small (53.63%). We noticed that younger birds having 10-20 weeks of age are more prone to be affected with avian mycoplamosis with an ...

The chicks were placed in an open shed house and were exposed to two different environmental temperature and humidity in summer season. Chicks as hatched broilers belonging to 3 strains Cobb-500, Hubbard Classic and Arbor Acres, 45 of each strain were reared in summer season; having 135 with 3 replications 15 broilers per pen. Body weight and feed consumption first and second weeks of age were significant differences (P<0.05 and P<0.001) in Cobb-500, Hubbard Classic and Arbor Acres in summer season. There was no significant differences (P>0.05) in body weight and feed consumption among the three broiler strain at third weeks and fourth weeks of age. The feed conversion ratio among the three broiler strain at first and second week of age were significant differences (P<0.05). In second weeks, the significant differences (P<0.05) of mortality were observed in three different broiler strain and dressing percentages were significantly differed (P<0.05) in summer season at the end of fourth weeks of age. It may be concluded that Cobb-500 may perform the best in summer season than in Hubbard Classic and Arbor Acres due to dressing yield. Hubbard Classic of the later two strains may also be recommended for commercial boiler production, but priority may be given to the Cobb-500 strain.

Eggs act as an important carrier of food-borne pathogen worldwide. The study was conducted to identify the prevalence and antibiotic resistance pattern of E. coli, Salmonella spp., and Staphylococcus spp., in eggs isolated from farms and different markets of Rajshahi, Bangladesh. A total of 60 eggs were collected randomly between April to December 2019. The isolation and identification of bacterial pathogen was done in accordance with standard procedures. The bacterial isolates were subjected to antibiotic susceptibility testing against seven commonly used antibiotics using Kirby-Bauer disk diffusion method. An overall prevalence of E. coli, Salmonella spp., and Staphylococcus spp. were found to be 35.0%, 28.33%, and 23.33%, respectively. E. coli were found highly resistant to penicillin (100%), tetracycline (80.95%), ampicillin (100%), and ery...

The findings show that women were nearly two times more willing than men to adopt improved rearing technologies related to family poultry production. Both women and men are impacted indifferently by lower adoption of scientific poultry-keeping technologies. Women are independently facing more problems in access to knowledge, training, services, marketing systems, and financial services related to family poultry production. Despite having many limitations, it is clear that family poultry empowers women through asset accumulation and increasing their decision-making ability in the families and the broader community. The study also highlights the necessity of considering an engendered approach in policy and operational level for the family poultry development.

The study was conducted to identify the prevalence and antibiotic resistance pattern of E. coli, Salmonella spp., and Staphylococcus spp., in eggs isolated from farms and different markets of Rajshahi, Bangladesh. A total of 60 eggs were collected randomly between April to December 2019. The isolation and identification of bacterial pathogen was done in accordance with standard procedures. The bacterial isolates were subjected to antibiotic susceptibility testing against seven commonly used antibiotics using Kirby-Bauer disk diffusion method. An overall prevalence of E. coli, Salmonella spp., and Staphylococcus spp. were found to be 35.0%, 28.33%, and 23.33%, respectively. E. coli were found highly resistant to penicillin (100%), tetracycline (80.95%), ampicillin (100%), and ery...

Birds under semi-intensive system had free access to outside the house for taking natural feeds and supplement 50g balanced feed per bird per day. Birds were reared intensive and on an average 100 grams of feed was offered per day to each bird. In the study, 24 chicken from the farming system and 24 chicken from the semi scavenging system were used and slaughtered at 48 weeks of age by the following standard procedures and carcass characteristics were recorded. The results revealed that live weight, dark meat (%), breast meat(%), thigh meat (%), drumstick meat (%), skin (%), neck(%) and wing meat(%) of chicken from the farm were significantly higher to those kept in the semi scavenging system and rest were higher in semi scavenging system. Deshi chicken of semi scavenging were 20.24% heavier than that of farm. Deshi and Sonali chicken under farming system had higher in dressing (%), dark meat (%), breast meat (%), thigh meat (%), drumstick meat (%), wing meat (%) compared to semi scavenging counterpart. On the other hand, semi scavenging reared RIR and Fayoumi had higher in dressing (%), breast meat (%), breast: dark meat, neck (%), gizzard (%), liver (%) and spleen (%) than from farm chicken. From the study, it is concluded that higher and better carcass characteristics were obtained in farm but performance of Deshi chicken was better indicating higher meat both in farm and semi scavenging system. Better non-carcass components were found under semi scavenging system as compared to farming system of management.

The result draws attention to the widespread acknowledgment of the critical roles of gender in family poultry production system. The results show that women hold the maximum of the ownership (90.58%, p=0.0001) and responsible for the caring of (93.94%, p=0.0001) family poultry in Bangladesh, likewise other developing countries. The result reveals that women control over the decision-making for the selling of eggs and birds in Bangladesh. Women mostly (94.58%) hold the knowledge useful in the prevention and treatment of poultry illness; however, their role was found low (3.46%) in buying medicine and vaccines for poultry as compared to men (96.54%) in Bangladesh. The findings show that women were nearly two times more willing than men to adopt improved rearing technologies related to family poultry production. Both women and men are impacted indifferently by lower adoption of scientific poultry-keeping technologies. Women are independently facing more problems in access to knowledge, training, services, marketing systems, and financial services related to family poultry production. Despite having many limitations, it is clear that family poultry empowers women through asset accumulation and increasing their decision-making ability in the families and the broader community. The study also highlights the necessity of considering an engendered approach in policy and operational level for the family poultry development.
