The Pabna is one of the potential local cattle breeds in Bangladesh regarding milk production and its nutritive quality. The aim of the study was to know the effect of lactation length, parity and management on production performance and nutritional/physiochemical composition of the milk of local Pabna cows. Besides the regular milking, 15 days’ interval test day milking was recorded from 12 local Pabna cows with different lactation period (up to fifth month of calving) from BLRI Regional Station, Baghabari during January-September, 2018. In addition, 12 and 16 milk samples (200 ml/sample) were collected from the cows raised at BLRI Regional Station and the community of Dairy Development Research Project at Bera, Pabna district during June, 2018, respectively. Data were analyzed in an ANOVA of Completely Randomized Design and independent sample t-test, respectively, using SAS version 9.1.3 (SAS Institute Inc., Cary, NC, USA) including Tukey’s HSD post hoc test to separate means. The average daily milk yield was significantly (p<0.05) higher during the first month (4.62 L) of lactation and the lowest value recorded at 5th month (3.50 L). Among the test days milking better yield observed at 15 days (4.79 L) of experimental lactation period (p<0.05). The effect of lactation stages and parity number had no significant variations (p>0.05) on nutrient compositions of local Pabna cows’ milk in both on-station and community. However, the overall characteristics of milk between on-station and community had significant differences on the composition of total solids (p<0.001), SNF (p<0.001), fat (p<0.01), and protein (p<0.05) where the highest values found as 14.81, 8.65, 6.17 and 3.53% at on-station, respectively. The first month of lactation observed as best milk producing period among the five months and the management system had positive association with milk composition of local Pabna cows. Asian J. Med.

The objective of this study was to clarify the inside of socio-economic condition and cattle production scenario in few areas of Pabna district. Data of socio-economic condition of farmers, cattle population, genotype and overall management were collected from three villages at Bera upazila of Pabna district during August to September in 2017. The collected data were tabulated and analyzed following one-way ANOVA including descriptive statistics. It was observed that the age of farmers were average 42 years with 19 years of average farming experiences. Agriculture was found as primary occupation (47.37%) followed by house wife (15.79%) and animal husbandry (10.53%). Among the total livestock population, 52% (n=286) was cattle with different genotypes but the frequency of local Pabna cattle was highest (70%). About 79% cattle were reared intensively at home because the areas were surrounded by water. The average peak day milk yield (4.56 liters) of local Pabna cattle was significantly (p <0.001) lower than Holstein crossbred (7.43 liters). The cattle feeding system was mostly intensive (77%) followed by semi-extensive (23%) with 60%, 49% and 98% restricted feeding for straw, green grass and concentrate feeds in the studied households. The capacity building training of farmers including different farm oriented facilities would enhance a dairy development programme in those areas from local Pabna cattle which could contribute their socio-economic condition as well.

The study was aimed to reveal the morphological features of local Pabna cattle at Bangladesh Livestock Research Institute (BLRI), Regional Station, Sirajganj and community levels. Data of various morphological features were collected from total 24 cattle from on-station and 8 cattle from community. It was observed that most of the morphological features were not varied between the studied cattle populations except body length, height at wither, pelvic length, tail dock circumference and mouth circumference (p <0.05). Pigmentation pattern revealed that light red was dominated for coat color in both cattle population while black color was most frequently observed in muzzle, eyelid, eyelash, horn, hoof, dew claw and tail switch. As most of the phenotypic observation and pigmentation patterns were unique between two existing Pabna cattle population, an open nucleus breeding system might be enhanced the desire dairy breed development from those cattle population regarding the uniformity of morphological features.Res.

A heated vertical flat plate in the presence of heat generation is an extremely significant technological issue, and many academics have studied this sort of problem. A vertical plate submerged in a fluid with varying viscosity will be used in this research to investigate the effects of variable viscosity and thermal conductivity on heat generation free convection flow. The boundary layer equations in this section are two-dimensional, laminar, and unstable. The fundamental governing equations are turned into non-dimensional governing equations by using the necessary variables. Using the Crank-Nicolson implicit finite-difference technique, these equations are solved numerically. Viscosity and thermal conductivity are temperature-dependent properties of a viscous, incompressible fluid. Variations in the study's numerous parameters will reveal and compare the velocities, temperatures, local skin friction, and local heat transfer co-efficient profiles. There will be a comparison between the current numerical data and previously reported data findings. Besides that, we'll compare our current work numbers to those of past released publications. Graphs and tables will be used to display the findings for a variety of key physical characteristics.

There were 17 districts under Dhaka, Chottogram, Sylhet, Rajshahi, Khulna and Mymensingh divisions selected for this study on the basis of Turkey farming. The total 52 number of farmers interviewed to conduct this study. Turkey rearing is a profitable agricultural practice to meet the protein requirement in developing countries like Bangladesh. This is not only a source of protein but also a rich source of minerals and vitamins. The semi-intensive rearing of turkey requires low capital investment and labor cost. The main objectives of the study were to know the present status of feeding and rearing system, problems and prospects and benefit cost ratio of turkey rearing in Bangladesh. The information that collected from the respondents were age, education, main occupation, family members, training, annual income, number of turkey in each batch, name of strain, mortality rate, vaccination and medication practice, current situation of antibiotic and growth promoter use, use of footbath, use of disinfectant for spraying in inside and outside of the farm, percentage of antibiotic and feed additives withdrawal period before marketing, source of vaccine and medicine at farmer level, consultants of the farmers for vaccine and medicine specially antibiotic use, vaccination and medication cost in a batch. The average cost for production of one kg meat is BDT 231.177 and average market price of one kg meat was about BDT 452.34. Asian Australas. J. Food Saf. Secur. 2019, 3(1), 48-52
