  • Reciprocal effects among local breeds and additive and heterosis effects were estimated for total milk production per lactation (TLP), lactation length (LL) and daily milk yield (DMY). Procedures for an optimum crossbreeding system were examined by comparing various crossbred combinations. Three data sets were chosen from the total records collected from 1962 to 1997. Data set I with a total of 5,938 records composed of 9 breed groups for reciprocal crosses, data set II with a total of 6,064 records composed of 5 breed groups for additive and heterosis effects and data set III with a total of 10,319 records composed of 42 breed groups for optimum crossbreeding system were analyzed. The least squares ANOVA was used. The reciprocal crosses between Red Sindhi and the Bangladeshi Local showed significant difference. When the Red Sindhi was used as cow, the cross was superior to the opposite in terms of the three performance traits. The results showed that additive breed effects on both TLP and DMY were positive and highly significant between Bos indicus and Bos taurus, whereas the individual heterosis effects were not significant. In general, any local breeds were improved two to three times by crossing with the Friesian once or twice. However, the effect was reduced when the grading up with the Friesian was repeated more than twice. On the other hand, when the local breed was crossed with the other breeds such as Holstein and Jersey, the improvement of TLP was less. Crossing the F1 cows with the Friesian bull gave further improvement. Almost the same trends were found also for LL and DMY. The local breeds and their crosses are raised mainly for draft animals, then it is recommended that the crossbreds between the local cows and Friesian are used for dairy purposes and more than 75% Friesian blood is used for beef.

  • Protein polymorphism of native and red jungle fowls in Nepal was analyzed by electrophoresis. Blood samples were collected in the areas of Solu, Jomson road, Kathmandou, Pokhara and Low land. Out of 17 loci, polymorphism were found at nine loci in native fowls and at three loci in red jungle fowls. The proportion of polymorphic loci ($P_{poly}$) of native and red jungle fowls were $0.529{\pm}0.121$ and $0.176{\pm}0.095$, respectively. The five fowl populations in Nepal formed a different cluster from Sri Lankan and Bangladeshi fowl populations. When the gene frequencies of polymorphic loci were compared between the native fowl populations of Sri Lanka, Bangladesh and Nepal, $Amy-1^A$, $Es-1^A$ and $Akp-2^A$ genes showed inclination of south to north.

  • This study investigated the comparative advantages of the Bangladeshi and Vietnamese apparel industries using Global Value Chain (GVC) framework. In this study, the GVC framework was expanded to include social and environmental sustainability issues. Secondary data, for the 2012 - 2013 period, were collected and analyzed for each component of the apparel GVC. The findings indicated that while both countries have unique comparative advantages, Vietnam clearly emerged as a leader on many GVC components. Bangladesh's comparative advantage lies in lower wages, producing high volume orders, and lean manufacturing. In spite of Vietnam's higher labor costs, it has comparative advantages in higher productivity, skilled and trained workers, manufacturing of intricate styles of high quality, agility and flexible manufacturing, more developed infrastructure and logistic services as well as greater social and environmental compliances. This study contributes towards insight into best sourcing fit for fashion brand business models. Based on the findings, fashion driven companies offering more complex styles at a faster rate will benefit from choosing Vietnam. In contrast, Bangladesh might be a better choice for high volume driven companies that offer basic apparel and better value for their consumers. From theoretical perspective, the research makes an important contribution by expanding the GVC framework.

  • The genetic factors that contribute to the development of coronary artery disease (CAD) are poorly understood. It is likely that multiple genes that act independently or synergistically contribute to the development of CAD and the outcome. Recently, an insertion/deletion (I/D) polymorphism of the human angiotensin I-converting enzyme (ACE) gene, a major component of the renin-angiotensin system (RAS), was identified. The association of the ACE gene D allele with essential hypertension and CAD has been reported in the African-American, Chinese, and Japanese populations. However, other studies have failed to detect such an association. It has been suggested that these inconsistencies may be due to the difference in backgrounds of the population characteristics. In the present study, we investigated the I/D polymorphism of the ACE gene in 103 subjects of both sexes, consisting of 59 normal controls and 44 patients with hypertension. The allele and genotype frequency were significantly different between the hypertensive and control groups (p < 0.01). Among the three ACE I/D variants, the DD genotype was associated with the highest value of the mean systolic blood pressure [SBP] and mean diastolic blood pressure [DBP] (p = < 0.05) in men, but not in women. In the overall population, the mean SBP and DBP was highest in DD subjects, intermediate in I/D subjects, and the least in II subjects.

  • In order to develop specific genetic markers and determine the genetic diversity of Bangladeshi native cattle (Pabna, Red Chittagong) and exotic breeds (Sahiwal), randomly amplified polymorphic DNA (RAPD) analysis was performed using 12 primers. Genomic DNA was extracted from 20 cattle (local and exotic) blood samples and extracted DNA was observed by gel electrophoresis. Among the random primers three were matched and found to be polymorphic. Genetic relations between cattle's were determined by RAPD polymorphisms from a total of 66.67%. Statistical analysis of the data, estimating the genetic distances between cattle and sketching the cluster trees were estimated by using MEGA 5.05 software. Comparatively highest genetic distance (0.834) was found between RCC-82 and SL-623. The lowest genetic distance (0.031) was observed between M-1222 and M-5730. The genetic diversity of Red Chittagong and Sahiwal cattle was relatively higher for a prescribed breed. Adequate diversity in performance and adaptability can be exploited from the study results for actual improvement accruing to conservation and development of indigenous cattle resources.

  • Bangladeshi indigenous chickens of mixed ages vaccinated twice at a three week interval with either conventional vaccines-$F_1$ (ocular) and M (mukteswar, Intramuscular), or heat resistant $V_4$ vaccine administered by either the ocular or oral routes, all showed satisfactory hemagglutination inhibition antibody (HI) responses and protection against Newcastle Disease (NCD) challenge persisting for four months. The antibody response to $F_1$ and M was higher than for $V_4$, which was similar whether administered by the ocular or oral routes. All vaccinated treatments have a significant level of protection compare to the control group (p<0.01). No significant difference (p>0.05) in the protection against controlled challenge with virulent NCD virus was found between vaccinated groups.

  • The crude alcoholic extracts of various parts of five different Bangladeshi mangrove plants (Amoora cucullata, Caesalpinia bonducella, Cerbera odollam, Derris uliginosa and Sonneratia caseolaris) were screened in-vitro for anti-oxidant activity using the 1,1-diphenyl-2-picryldydrazyl-hydrate (DPPH) free radical scavenging assay. Of all of them, the ethanolic extracts of the leaves of Derris uliginosa and Sonneratia caseolaris showed potential antioxidant activity ($IC_{50}$: 94.406 and 26.30 mg/ml respectively) whereas the ethanolic extracts of aerial parts of Derris uliginosa, barks of Cerbera odollam and leaves and stems of Caesalpinia bonducella showed moderate activity ($IC_{50}$: 125.89, 211.35 and 301.99 mg/ml respectively). Mild anti-oxidant activity was observed with the methanolic extract of leaves of Amoora cucullata and ethanolic extracts of fruits of Cerbera odollam.

  • The utmost intention of this work is to identify various field areas which are most prevalent in library and information science education. The study also denotes the rate of tendency on the rapid growth and development of research production among information specialists in Bangladesh. In order to carry out the study, an extensive literature review was carefully done to collect the basic elements of research patterns. It is noted that in the period of 1980-2016, 200 articles were published in library and information science by Bangladeshi researchers in 62 journals. In this article a total of 200 articles were reviewed. The result of the present study shows that the ratio of female authors had fewer contributions than male authors did. The majority of articles were published from the United Kingdom. The study also shows that the largest numbers of articles (19 papers, 9.50%) were published in the Social Science Journal of the University of Rajshahi from Bangladesh. The paper also shows that about 71.50% of papers have been cited while 28.50% of papers did not receive any citation. The present research might be helpful for revealing the country's research trends in library and information science. However, this study may also inspire development of a subject-based indigenous database and can act as an important device for research scholars.

  • With the paramount importance of key account management in business-to-business relationship, today companies are using this approach as a strategic weapon in their selling efforts targeted at the most important customers to solve their complex requirements with special treatment that eventually ensures both parties' financial and nonfinancial objectives. The aim of this paper is to investigate the level of key account management performance among the export-oriented readymade garments companies in Bangladesh with regards to company's experience in business, size of the company and key account serving capacity of the company. Using a questionnaire, data from 112 readymade garments companies in Bangladesh were collected and analyzed using descriptive analysis and ANOVA to test the level of key account management performance. Results show that the level of key account management performance by the garments companies did not vary by the company's experience in business and size of the company respectively. In contrast, the level of key account management performance was found to be different concerning high, medium, and low customer service capacity. Apparently, companies with big number of customers show better performance than companies with small number of customer. Implications for this study are discussed along with suggestions for future research avenues.

  • An actinomycete strain was isolated from northern part of Bangladesh and identified as a new Streptomyces species on the basis of its morphological, biochemical, cultural characteristics and 16S rRNA data. Attempts were made to optimize the culture conditions for the production of antimicrobial metabolites by this strain. Antimicrobial metabolites production was started after 7 days of incubation of culture broth and reached its maximum levels after 10 days and thereafter gradually decreased. The maximum production of antimicrobial metabolites was obtained when the culture medium pH was adjusted to 8. The optimum temperature for antimicrobial metabolites production was $39^{\circ}C$, indicated the new strain as mesophilic organism. Basel medium supplemented with glucose and yeast extract as carbon and nitrogen sources, respectively, was proved to be the best for the production of bioactive metabolites. Maximum production of bioactive metabolites was when NaCl concentration was 1% and among different minerals tested, $K_2HPO_4$ and NaCl showed positive influence on antibiotic production by the strain.
