Although tilapia is one of the most cultivated fish species in Bangladesh owing to its high growth rate, comparatively easy culture practices, higher survival rate and short culture period but low market preference marked it as a low-priced fish. Various approaches have been adopted to enhance consumer acceptability and ensure better use of tilapia, including the production of value-added products such as tilapia-prepared fillets, which attract increasing interest. Therefore, the current study was designed and carried out in order to prepare tilapia fillets and to estimate their shelf life at frozen (-18±20C) and refrigerated (4±10C) temperatures. Fillets were produced from tilapia collected from local fish markets of Sylhet city, Bangladesh with according to Good Manufacturing Practices (GMP) established by International Standards Organization (ISO) and packed in polyethylene bags. Proximate composition, total volatile base nitrogen (TVBN), peroxide value (PV), pH, total plate count (TPC) and sensory properties of fillets were analyzed to determine shelf-life. A portion of the fresh fillet sample was immediately analyzed and the remaining portions were preserved for up to 12 and 90 days at refrigerated and frozen storage temperatures, respectively. Results revealed that, at a definite interval of time, changes in the chemical, microbial and sensory attributes of tilapia fillets were found to be more pronounced in refrigerated storage conditions than fillets stored in frozen conditions. The shelf life of refrigerated and frozen tilapia fillet samples was 9 and at least 90 days, respectively, per the results of sensory, microbial and chemical evaluation. Res. Agric., Livest.

The main purpose of the study was to determine the participation of Local Service Providers (LSPs) in systemic market approaches (SMA) in dairy sectors in two Upazilla Pirgacha and Badargonj under Rangpur district. Ninety-nine (99) LSPs were randomly selected as sample from an updated list of 495 LSPs. A pretested and structured interview schedule was used to collect data from the respondents during 16 August to 17 September 2018. Simple and direct questions with different appropriate scales were used to obtain information. Descriptive statistics, correlation, and multiple regression analysis were used. The top-ranked activities regarding the participation of LSPs was referral linkage with DLS for the critical or serious condition of livestock treatment, linkage with dairy producers’ group to assess the demand of information, develop collection point’s adjacent place of the community. Slightly above four-fifths (84.8 percent) of the respondent had high participation in systemic market approaches. Correlation analysis indicated that among seven selected characteristics of the respondent’s annual income, cosmopoliteness, training received, innovativeness, and extension media contact of the respondents had significant positive relationship with their participation in SMA, however, age and family size had no significant positive relationship. Regression analysis indicated that cosmopoliteness, training received, innovativeness, and extension media contact of the respondents had a positive contribution with their participation in SMA. The top-ranked problem (1st) faced by the LSPs was ‘legal permission from Government authority and apparently, the lowest proportion of LSP faced problems on ‘Lack of vehicle service for their movement’ service on dairy subsectors.

The present study revealed on temporal variations of length, weight and condition of Heteropneustes fossilis (Bloch, 1794) in the Ganges River, Northwestern Bangladesh. Total 1161 individuals of H. fossilis were caught by various habitual fishing gears such as seine net, cast net and gill net during January to December 2019. For every specimen, body weight (BW) was taken by digital balance to the accuracy of 0.01 g and total length (TL) was taken using a measuring board. Relative condition factor (KR) was assessed by KR = W/(a×Lb), where W is the BW in g, L is the TL in cm and a and b are length-weight relationships parameters. The value of KR ~ 1 specifies good health, >1 specifies over bodyweight as compared to length, whereas <1 suggests a fish in poor condition. The TL varied from 8.5-28.7 cm whereas the BW was 37.17–2250 g. The overall KR for H. fossilis was 0.99-1.06 in the Ganges River. The highest KR was observed in May while the lowest was in January. The KR was significantly correlated with BW in the Ganges River. The outcomes of the study will be helpful for future management of this fish in the Ganges river ecosystem as well as adjacent water bodies. Res. Agric., Livest. Fish.8(2): 259-266, August 2021

The objectives of this study was to assess the extent of problems faced by the farmers in catfish culture with randomly selected 120 catfish cultivars in Trishal upazila under Mymensingh district. A structured questionnaire was used to collect data. Based on the level of problem faced by the farmers in catfish culture they were divided into three groups; less problem, moderate problem and high problem and it was observed through survey that the majority (60 %) of the farmers faced moderate problem while 22.50% percent of the farmers faced low problem and 17.50% farmer faced high problem. Farmers’ problem face was influenced by their media contact for fish farming, training exposure, level of education and organizational participation. Farmers having higher media contact, higher training participation, higher educational level and higher organizational involvement faced lower problem in catfish culture. On the basis of Problem Faced Index (PFI) score calculated to rank the problems, it was observed that high price of feed ranked most severe problem followed by unavailability of quality feed, high price of vaccine and medicine and low production and lack of local market. The findings may contribute in formulating policies to reduce farmers’ problem in catfish culture. Res. Agric., Livest. Fish.8(2): 241-248, August 2021

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to assess the response of foliar application of boron on growth and beet weight. The experiment consisted of foliar application of boron at four concentrations viz. 0, 50, 100 and 150 ppm, and frequency of application thrice viz. once at 40 days after emergence (DAE), twice at 40 and 65 DAE and thrice at 40, 65 and 90 DAE. The experiment was laid out in a randomized complete block design with three replications. Growth traits and average beet weight were significantly influenced by boron concentration and frequency of application. At later stage of growth (at 140 days after sowing) the tallest plant, number of leaves/plants, shoot dry weight, root dry weight and root length were recorded in 150 ppm boron with three times foliar application at 40, 65 and 90 DAE. The highest average beet weight (1.04 kg/beet) was recorded in 150 ppm boron with foliar application thrice at 40, 65 and 90 DAE followed by 100 ppm boron with foliar application at 40, 65 and 90 DAE while the lowest one 0.28 kg/beet was found in control. So, from the result it can be concluded that 150 ppm boron with foliar application at 40, 65 and 90 DAE seems to be promising in terms of growth attributes and average beet weight/plant of tropical sugar beet.

Twenty female Jamunapari goats of live weight of 10.5 ± 1.2 kg at 08± 0.56 months of age were used for 240 days feeding trial. Goats were assigned to four dietary treatments in a completely randomized design with five (05) goats in each group. All animals were supplied ad libitum green grass and water. They were supplied 150, 200, 250, 300 gm concentrate mixture per day with roughage for group T1, T2, T3, and T4 respectively. Total dry matter (TDM) intake (413.2, 456.67, 489.2 and 495.7g/day) in groups T1, T2, T3, and T4, respectively, was significantly (p≤0.01) influenced by the level of concentrate in the diet. Average total digestible crude protein (DCP) intake (3.1, 3.5, 3.9, 4.0 g/kg body weight and average total digestible nutrient (TDN) intake 21.1, 22.3, 24.7, 25.1 g/kg body weight was significantly (p≤0.01) higher in group T4 and lower in group T1. The nutrient intake and digestibility were also significantly higher (p≤0.01) in T4 group. The percent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), crude fiber (CF), ether extract (EE) and nitrogen free extract (NFE) were 70.1, 75.99, 73.50, 67.24, 62.13 and 49.60%, 73.14, 76.97,76.84, 68.32, 64.04 and 53.25%, 75.45,78.44,78.67,70.43,68.43 and 59.77%, 79.56, 80.16,81.69,72.45,70.82 and 63.09% in T1, T2, T3 and T4 group, respectively. Reproductive performances, birth weight of kids and litter size did not differ significantly between groups, but had significant effect on feed digestibility and milk production. Daily 300 gm concentrate mixture along with roughage is necessary for better growth, production and reproduction performance of Jamunapari doe in semi-intensive system. Res. Agric., Livest.

The main purpose of the study was to investigate the knowledge and practices of women farmers on organic farming. The study was conducted in two union of Nilphamari Sadar upazila namely Lakshmi Chap and Palashbari under Nilphamari district. Ninety-two (92) women farmers were randomly selected as sample from an updated list of 120 women farmers. Data were collected by a pre-tested interview schedule during 1st to 30th October 2020. Simple and direct questions with different appropriate scales were used to obtain information. Descriptive statistics, correlation and multiple regression analysis was used for the present study. Majority of the respondents know about rotating crops, using different wastes, composting, limiting the use of synthetic/ chemical fertilizers, trap method, and mulching as part of organic farming practices. Majority of the respondents opined that they were practicing more than once „Using organic fertilizer‟, „using plant waste‟, and „using kitchen waste‟ for the last 12 months. Slightly above four-fifths (83.7 percent) of the women farmers had medium practices on organic farming, while 14.1 percent women farmers had high practices on organic farming, and only 2.2 percent women farmers had low practices on organic farming. Thus, a proportion of 85.9 percent of the women farmers low to medium practices on organic farming. Correlation analysis indicated that among nine socio-economic profile educational qualifications, farm holding, training received, extension media contact and innovativeness of women farmers had significant positive relationship with their practices on organic farming. However, age, organic farming experience, annual family income and cosmopoliteness had no significant positive relationship with their practices on organic farming.

Any genetic improvement in dairy cattle requires information on productive and reproductive performance in the given population. Animals have been selected to improve their productivity in order to increase the profitability to the farmer. As a result, selection of animals is made for higher production and a shortened productive life. The reproductive performance of Friesian cows under intensive and semi-intensive management system in Bangladesh is poor. Animal selection has historically been based on production traits, and not much attention was given to AI recording. Many attempts were taken scatterly to increase productive and reproductive potential of Bangladeshi cattle for different periods with variable achievements. Therefore, in this review article we have addressed the new tools and information that could be used to determine the level of productive and reproductive performance and to evaluate genetic factors using admixture analysis of cows bred by AI sires which affect reproductive traits of crossbred Friesian dairy cows reared in selected areas in Bangladesh.

Animals have been selected to improve their productivity in order to increase the profitability to the farmer. As a result, selection of animals is made for higher production and a shortened productive life. The reproductive performance of Friesian cows under intensive and semi-intensive management system in Bangladesh is poor. Animal selection has historically been based on production traits, and not much attention was given to AI recording. Many attempts were taken scatterly to increase productive and reproductive potential of Bangladeshi cattle for different periods with variable achievements. Therefore, in this review article we have addressed the new tools and information that could be used to determine the level of productive and reproductive performance and to evaluate genetic factors using admixture analysis of cows bred by AI sires which affect reproductive traits of crossbred Friesian dairy cows reared in selected areas in Bangladesh. \u0000Res.

The experiment was carried out to investigate the effect of rhizobium inoculum and phosphorus fertilization on nodulation, growth, and yield of soyabean cv. Binasoybean-2 at the area of Chamberkella, East Subarnachar Upazila, Noakhali, Bangladesh, from mid-January to first week of May 2018. Four levels of Rhizobium inoculation viz: 0, 25, 50 and 75 g kg-1 and four levels of phosphorus viz: 0, 18, 36 and 54 kg P ha-1 were applied. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The effect of interaction of different combinations of Rhizobium inoculation and phosphorus rates showed regular trend, although their effects on some of studied growth, and yield parameters were insignificant but most of the growth and yield parameters were significant. Among sixteen treatment combinations the highest grain yield (2.217 t ha-1) was obtained from the treatment combination of 50 g kg-1 Rhizobium inoculation and 36 kg ha-1 phosphorus which was statistically identical with 50 g kg-1 Rhizobium inoculation with 18 kg ha-1, the lowest yield (1.367 t ha-1) was recorded with control treatment.
