The objective of this study was to know the existing buffalo milk trade and dairy products production status along with scope for buffalo milk product branding. Hence, a face-to-face interview with eighteen milk traders and processors were performed through simple random sampling method. Milk traders and processors were above 25 years old (94%) and above 5 years (89%) experienced in dairy business. The findings exposed that 11% of the participants were involved in milk collection and selling, 39% were directly involved in product manufacturing, and 50% were engaged in milk collection and processing. Among the manufactured dairy products, traditionally made fermented doi was the best - selling dairy product in the Bhola district. About 47% participants desired to incorporate fat-rich dairy products into their production processes. In general, milk traders sold the maximum amount of milk monthly to doi manufacturers (1453 L), followed by local customers (1175 L), sweetmeat manufacturers (1000 L), restaurants (257 L), and household consumers (250 L). Results showed that buffalo milk prices varied significantly (P<0.001) over the year. The peak buffalo milk price (122 BDT/L) was recorded between November and December, and the off-peak price (82 BDT/L) was between March to May. Data indicated that about 43-50 BDT profit derived through per kg doi and sweetmeat selling. Milk traders and processors mentioned that studied areas had greater shortage of milk preservation facilities. Overall, the findings of this study may give some context for developing sustainable buffalo milk and dairy products value chain in Bangladesh. Res. Agric., Livest. Fish.8(3): 301-310, December 2021

The aim of the present study was to know the normal haemato- biochemical profiles of black Bengal goats in Bangladesh. Blood samples were collected from Jugular vein of 20 Black Bengal goats which were divided into 5 groups (4 goats in each group) on the basis of age, sex, nutritional and feeding status. The whole blood was analyzed for hematology, plasma and serum samples for biochemical analysis. The results of the present study demonstrate the normal haemato-biochemical values of the Black Bengal goat breeds with their age specificity. Total RBC (15.15 ± 1.29 million/cumm), haemoglobin (7.04 ± 1.02 g/dl), total WBC (11.64 ± 1.12), differential leukocyte counts of neutrophils (70.89 ± 2.06%), lymphocyte (23.79 ± 1.69%), eosinophil 2.1%), basophil (2.3%), MCV (35.04 ± 0.47) and PCV (26.98 ± 1.49%). This study also reveals the normal bio-logical profile counts as total protein (69.47±2.31 g/L), Albumin (42.47 ± 2.31g/L), Globulin (27.32g/L), Phosphorus (3.46 ± 1.19), blood Urea (22.97 ± 0.58), Creatinine (0.645mg/dl), ALT (20.32U/L), ALP (91.59 U/L), GGT (37.46 U/L), IgG (18.91 ± 1.14 g/L), IgM ( 2.87 ± 0.18g/L), gA (.031 ± 0.12g/L) and IL-6 (1.69±0.15g/ml). The study found higher number of RBC (million/cumm), WBC (Thousands/cumm), and PCV% in the goats of age 3 years and above (18.02 ± 1.27, 14.72 ± 1.19, and 28 ± 3.2), respectively. Besides, Neutrophils% and total protein was found higher (76.289 ± 14.5%, 77.52 ± 8.43 g/L), respectively in the Black Bengal goats of 6 months to 1 year age. Present results stated some significant variation of parameters between goats of various ages; on the other hand, some shows no significant variation at all. Res. Agric., Livest.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University to observe the effect of sowing methods and weeding regimes on the yield of sesame. The experiment comprised of two factors. Two methods of sowing i.e., broadcasting and line sowing (S2), and six weeding regimes- control (T0), weed free (T1), one hand weeding at 15 DAS (T2), two hand weedings at 15 and 30 DAS (T3), three hand weedings at 15, 30 and 45 DAS (T4) and application of Panida (Pendimethalin) herbicide (T5) at 3 DAS. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Almost all the yield characters of sesame were affected significantly due to sowing methods, weeding regime and their interaction. Result showed that the l ine sowing showed better performance regarding plant height (100.40 cm), number of branches (4.983) plant–1, number of capsules plant–1 (47.82), number of seeds capsule–1 (69.66), 1000–seed weight (2.96 g), seed yield (956.90 kg ha–1), stover yield (2167.0 kg ha–1), biological yield (3123.00 kg ha–1) and harvest index (31.45%) than that of broadcasting method. Also weed free treatment had the highest plant height (101.90 cm), highest number of branches (5.00) plant-1, highest capsule (47.08) plant–1, heaviest 1000–seed weight (3.28 g), highest number of seeds capsule–1 (76.22), highest seed yield (974.30 kg ha–1), stover yield (2947.0 kg ha–1) and biological yield (3922.0 kg ha–1) as compared to other treatments while unweeded plot had least significant effect among the whole yield and yield attributes of sesame. In case of interactions, both weed free treatment and herbicidal effect with line sowing methods produced the highest plant height, number of branches and capsules plant–1, seeds capsule–1, seed yield, stover yield and biological yield (109.80 cm, 5.967, 56.57, 81.53, 1054.0 kg ha–1, 3139.0 kg ha–1 and 4193.0 kg ha–1, respectively) as compared to other interaction combinations. The results of the study reveal that the weed free treatment along with line sowing would be the proper technique for higher production of sesame. But line sowing along with application of Panida herbicide would be the best combination for obtaining higher yield of sesame since it is not feasible for the farmers to keep their field weed free throughout all the growing periods.

To investigate the effect of graded level of acetic acid on the production performance and carcass characteristics of broiler, present study was conducted for a period of 35 days in a controlled shed. A total of 240 Cobb 500 day old broiler chicks were divided into four dietary treatment groups (T0, T1, T2 and T3), each group with three replications and each replication having 20 birds. Control group (T0) birds were fed with the basal diet without any acetic acid. Birds of T1, T2 and T3 group were treated with 0.1%, 0.2% and 0.3% acetic acid in drinking water, respectively along with basal diets. Recorded data were analysed in SPSS software by using ANOVA and significance level was considered as 5%. Results showed that, acetic acid has significantly (P<0.05) improved live weight, live weight gain, feed conversion ratio (FCR) and some meat characteristics (carcass weight, thigh weight and breast weight) of experimental broilers. However, there were no significant (P>0.05) differences were observed between control group and acetic acid treated groups of birds in terms of feed intake, dressing percentage, liver weight, heart weight and abdominal fat. Net profit was higher in birds treated with acetic acid than the control group and the best performances were observed in the birds treated with 0.3% acetic acid. Res. Agric., Livest.

The generalized length-length relationships of Chanda nama ((Hamilton, 1822) belongs to Ambassidae were studied separately for a period of a calendar year collected from the Old Brahmaputra River, Mymensingh, Bangladesh for male, female and combined populations. A total of 1170 specimens were examined where 599 were male and 571 were female. The standard length, fork length and total length of male ranged from 19 to 79 mm, from 23 to 90 mm, and 28 to 100 mm respectively. The standard length, fork length and total length of female were found from 15 to 81 mm, 24 to 89 mm, and from 29 to 100 mm respectively. The generalized relationships of standard length and fork length, fork length and total length, and standard length and total length of male, female and combined populations were FL = 1.08 SL+1.41, TL = 1.11 FL + 1.54 and TL = 1.20 SL+2.81; FL = 1.09 SL+1.23, TL = 1.12 FL+1.04 and TL = 1.22 SL+2.22; and FL = 1.09 SL+1.20, TL = 1.11 FL+1.27 and TL = 1.22 SL+2.38 respectively. The coefficient of determination (R2) revealed high values in all regression analyses. In length–length relationships, the coefficient of determination (R2) ranged from 0.973-0.990. The present findings of this study will be helpful for a well-organized and significant exploitation and regulation of the Chanda nama fishery in the Old Brahmaputra River and surrounding ecosystems.

Varietal selection and appropriate placement of nitrogen fertilizer could reduce the magnitude of nitrogen losses to a considerable extent and improve its use efficiency for better grain production. An experiment was carried out during the period from July to December at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to evaluate the effect of variety and nitrogen fertilizer management on the growth and yield of transplant aman rice. The treatments consisted of three varieties viz. BR11, BRRI dhan49 and Binadhan-7, and five nitrogen fertilizer managements viz. two depth of placement of USG (Urea Super Granule) and three split applications of prilled urea. The experiment was laid out in a randomized complete block design with three replications. The results showed that the effect of variety and nitrogen fertilizer management significantly influenced all the yield contributing characters except weight of 1000- grains, non-effective tillers hill-1 and panicle length. The highest grain yield (3.69 t ha-1) was obtained from Binadhan-7. In the case of nitrogen fertilizer management, the highest grain yield (4.32 t ha-1) was found from the 6 cm depth placement of USG. The highest grain yield (4.82 t ha- 1) was observed from the interaction of Binadhan-7 with the 6 cm depth of placement of USG. It may be concluded that Binadhan-7 with 6 cm depth of placement of USG appeared as the promising practice to maximize the yield of transplant aman rice. Res. Agric., Livest.

An experiment was carried out during the period from July to December at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to evaluate the effect of variety and nitrogen fertilizer management on the growth and yield of transplant aman rice. The treatments consisted of three varieties viz. BR11, BRRI dhan49 and Binadhan-7, and five nitrogen fertilizer managements viz. two depth of placement of USG (Urea Super Granule) and three split applications of prilled urea. The experiment was laid out in a randomized complete block design with three replications. The results showed that the effect of variety and nitrogen fertilizer management significantly influenced all the yield contributing characters except weight of 1000- grains, non-effective tillers hill-1 and panicle length. The highest grain yield (3.69 t ha-1) was obtained from Binadhan-7. In the case of nitrogen fertilizer management, the highest grain yield (4.32 t ha-1) was found from the 6 cm depth placement of USG. The highest grain yield (4.82 t ha- 1) was observed from the interaction of Binadhan-7 with the 6 cm depth of placement of USG. It may be concluded that Binadhan-7 with 6 cm depth of placement of USG appeared as the promising practice to maximize the yield of transplant aman rice. \u0000Res. Agric., Livest.

Plant spacing ensures uniform and optimum plant population and facilitates sufficient natural resources for crop growth which, in turns influences the crop yield positively. An investigation was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, during July to December 2017 to study the influence of plant spacing on the yield of double grained rice cultivar. The study comprised five spacing viz. 25 cm × 15 cm, 25 cm × 10 cm, 20 cm × 15 cm, 20 cm × 10 cm and 15 cm × 15 cm and two rice cultivars viz. a double grained rice cultivar and BRRI dhan49 and a double grained rice cultivar. It was laid out in a randomized complete block design with three replications. The double grained rice cultivar produced taller plant (155.65 cm), longer panicle (23.93 cm), higher 1000-grain weight (25.96) and higher straw yield (6.90 t ha-1), though the higher grain yield (3.68 t ha-1) was found in the test cultivar (BRRI dhan49). Planting at 20 cm × 15 cm produced the highest grain yield (3.70 t ha-1) which was at par with 25 cm × 15 cm, 25 cm × 10 cm and 20 cm × 10 cm while planting at 15 cm × 15 cm produced the lowest grain yield (3.13 t ha-1). The interaction of the double grained rice cultivar with all spacing combinations produced taller plants than the spacing combinations with BRRI dhan49. The higher grain yield (3.52 t ha-1) was found in the double grained rice cultivar with 20 cm × 10 cm spacing which was at par with the spacing of 20 cm × 15 cm and 25 cm × 15 cm, respectively; although BRRI dhan49 always produced the higher yield. The lowest grain yield (3.08 t ha-1) was recorded at the double grained rice cultivar with 25 cm × 10 cm spacing, however, the same treatment produced the highest biological yield (11.23 t ha-1) due to the highest straw yield (8.15 t ha-1). Hence, the spacing 20 cm × 15 cm might be recommended for the higher grain yield in the double grained rice cultivar Res. Agric., Livest. Fish.8(3): 273-279, December 2021
植物间距可确保均匀和最佳的植物种群，并为作物生长提供充足的自然资源，从而对作物产量产生积极影响。2017年7月至12月，在孟加拉国农业大学农学田间实验室开展了一项调查，研究了种植间距对双粒稻品种产量的影响。研究采用25 cm × 15 cm、25 cm × 10 cm、20 cm × 15 cm、20 cm × 10 cm和15 cm × 15 cm 5个间距和2个水稻品种，即双粒稻品种和BRRI dhan49和双粒稻品种。采用随机完全区组设计，有3个重复。双粒稻品种株高(155.65 cm)，穗长(23.93 cm)，千粒重(25.96)和秸秆产量(6.90 t hm -1)较高，而试验品种(BRRI dhan49)籽粒产量较高(3.68 t hm -1)。20 cm × 15 cm的产量最高(3.70 t hm -1)，与25 cm × 15 cm、25 cm × 10 cm和20 cm × 10 cm的产量相当，15 cm × 15 cm的产量最低(3.13 t hm -1)。双粒稻品种与所有间距组合的互作均比BRRI dhan49的间距组合植株高。20 cm × 10 cm的双粒稻产量最高(3.52 t hm -1)，与20 cm × 15 cm和25 cm × 15 cm的产量相当;尽管BRRI dhan49的产量总是更高。25 cm × 10 cm双粒稻的产量最低，为3.08 t ha-1，但由于秸秆产量最高(8.15 t ha-1)，其生物产量最高(11.23 t ha-1)。因此，双粒稻品种宜采用20 cm × 15 cm的间距，以获得较高的籽粒产量。,力所能及的。鱼类。8(3):273-279,December 2021

Fishing with otters is an ancient fishing technique in Bangladesh, exists only in the south-western part of the country with smooth-coated Otter (Lutrogale perspicillata). The present study was carried out to portray this unique fishing technique and to investigate otter fishers` livelihood status in Narail District. Fishing with otters is carried out at night in the Chitra and the Nabaganga rivers, involving at least four people, a boat, a net, 2-3 adult tamed otters and 1-2 immature trainee otters. The socio-economic conditions and livelihood status of the otter fishers` were found as not-satisfactory level whereas about 75% of total 36 fishermen were termed as very poor and they don`t have their own boat and nets for fishing. All of the surveyed fishers belong to the Hindu religion and less access to education, pure drinking water, and a healthy sanitation system. Due to scanty income, and resultant low-living standard, 14 otter fishers were found changed their ancient profession. Therefore, direct interventions are essential to support improved and sustainable socio-economic condition of the otter fishing community. Res. Agric., Livest. Fish.8(2): 249-257, August 2021

The experiment was conducted at Agricultural field laboratory in Noakhali Science and Technology University during the period from mid-January 2019 to 1st week of May 2019, to find out the growth, nodulation, and yield performance of soybean cv. BARI soybean 6 under different weeding regimes. The experiment consists of four treatments viz. T0 (No weeding), T1 (Weed free), T2 (Two hand weeding at 15 DAS and 30 DAS) and T3 (Three hand weeding at 15 DAS, 30 DAS and 45 DAS). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Characters like plant height, number of pod plant-1, number of effective pod plant-1, number of non-effective pod plant-1, number of seed pod-1 and yield varied significantly among the different weeding regimes. The highest seed yield (1.275- ton ha-1) was recorded at T1 (weed free) and the lowest seed yield (0.903-ton ha-1) was observed at T0 (No weeding) condition. The economic analysis of the treatments showed that farmers will be better off by adopting two weeding regimes and weeding at 15 DAS and 30 DAS is therefore recommended for high income. Res.

The present study was conducted to determine the prevalence of Fowl typhoid in apparently healthy, sick and dead birds at Rajshahi city corporation area of Bangladesh. A total of 500 birds (50 from each farm) and 30 different organs (liver from 10, ovary from 8, heart from 7, and caecal tonsils from 5) were randomly collected from different commercial poultry farms during the period from January 2018 to December 2018. The prevalence study was performed based on history, clinical signs, symptoms exhibited by the individual bird of a flock during the observation of farms, and illness of birds. The suspected birds were subjected to necropsy examination. During sample collection, clinical signs and gross necropsy changes were recorded very carefully. The collected tissues were fixed, processed, sectioned, stained, and studied light microscopically. The routine histopathological method was used for the detection of tissue-level alterations in Fowl typhoid infected cases. The prevalence of Fowl typhoid in apparently healthy birds of different poultry farms was 8.2%, and 23.33% of organs were involved. Grossly, the liver was enlarged, congested and revealed bronze discoloration with focal necrosis in the surface of the liver. Old raised hemorrhages were found in the caecal tonsils. Congested, deformed, and pedunculated ova were other important findings. Microscopically, the sections of the liver showing multifocal necrosis with infiltration of heterophils and reticulo-endothelial cells. Res. Agric., Livest. Fish.8(2): 201-209, August 2021
