Authors: Jalil MA , Akther S , Choudhury MP , Habib MA
Published: May 2020

The study was undertaken to evaluate the genetic progress of Black Bengal Goat (BBG) by estimating genetic parameters viz. heritability and breeding values for economically important productive and reproductive traits (birth weight, weight at 3, 6, 9 & 12 months, daily milk yield, lactation length, total milk yield and litter size of BBG goat population). Variance and co-variance components were analyzed applying Residual Maximum Likelihood (REML) approach by VCE 4.2.5 computer package. The heritability (h2) of birth weight was estimated as 0.2, which was low. The heritability estimates for 3-month weight (0.40), 6-month weight (0.50), 9-month weight (0.37) and 12-month weight (0.36) were found medium. Estimated h2 of daily milk yield, total milk yield and lactation length in this study were from 0.55 to 0.82.  h2 of litter size was 0.09. The maximum estimated breeding value (EBV) was found for 6 month body weight (12.94 kg), however, for daily milk yield, the value was 1.513 kg. The results found in this study revealed that genetic improvement of BBG for most of the traits is possible by selection and breeding.

Published: May 2020

The Myxovirus resistant gene (Mx) codes for Mx protein with antiviral activity. Mx gene has been found in yeast and vertebrates ranging from fish to humans. In the present study Mx gene and its diversity in chicken is reported. A total of 42 blood samples were collected from different groups of chicken and were analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). The diversity of Mx gene was enumerated by RFLP of PCR product with RsaI and SspI restriction enzyme. Mx gene was amplified from all the tested samples (100%) with the primers used. The primers amplified specific 100bp and 300bp DNA fragments from Mx gene. RFLP analysis of PCR product obtained with mismatched primers revealed that three types of Mx gene allele are prevailing in the tested samples; these are homozygous resistant Mx allelic gene (R/R), heterozygous Mx allelic gene (R/S) and homozygous sensitive Mx allelic gene (S/S). The proportions of each gene allele in the sampled chicken were 42.86% R/R, 42.86% S/S and 14.29% R/S. Interestingly, variation in Mx gene was observed within and between the groups of chicken. Present study has limitations like number of sample, species of bird sampled, etc. However, the study provides the genetic basis to some extent of chicken about resistance or sensitivity to avian influenza. To the best of our knowledge this is the first report of Mx gene related study in chicken in Bangladesh.

Published: May 2020

An experiment was conducted with Muscovy, Pekin and Desi white ducklings for a period of 98 days in three villages of Noakhali district in order to know the effect of feed supplementation on growth performance and cost of production under scavenging system of rearing. A factorial experiment (2×3) was designed for 2 feeding regimes (control and supplemented) and 3 genotypes of duck. The feed supplements consisting of a mixture of rice polish, broken rice and wheat bran @ 50, 30 and 20% respectively. At 98 days of age, final live weight, live weight gain, feed conversion efficiency and survivability were highest in Muscovy and lowest in Desi white irrespective of feeding regimes. The differences among the genotypes were statistically significant (P<0.01) for final live weight and live weight grain. Feed conversion ratio was better in Muscovy than in Pekin and Desi white. The profit margin (Tk. 68.31vs 16.96) and cost benefit ratio (2.38 vs 1.38) were highest for Muscovy and lowest for Desi white ducklings. Feed had a significant (P<0.01) effect on total cost and genotypes also showed significant effect (P<0.0) on total cost. The profit margin differed significantly among the genotypes of bird and feeding regimes. From the study, it may be concluded that Muscovy ducklings could be profitably reared through supplementary feeding of 60g concentrate mixture daily under scavenging system in the rural areas and should be marketed at the age of 6 weeks.

Published: May 2020

The study was conducted to determine fodder production, estimated profitability of fodder farmers and constrains to its production.In this regard, four study areas were selected from four districts viz: Dinajpur,Jessore, Kurigram andRangpur purposively considering the concentration of fodder production. A purposive sampling technique was followed for collecting primary data from the field. Two categories of sample farmerswere selected namely: i) Fodder Producer cum seller (FPS); ii) Fodder Producer cum Dairy owner (FPDO) having 1-2 dairy cows as small, 3-4 dairy cows as medium and 5 and above dairy cows as large farmer.A total of 160 fodder farmers were interviewed. Field survey method and focus group discussions were followed to collectnecessary data and information. Descriptive statistics were applied to meet the objectives and to get the desirable outputs.The study revealed that99 per cent FPS cultivatednapier (Pennisetumpur-pureum), whereas fodder producer cultivated90 per cent. The ratio of land under fodder production and farm size was 0.10 and 0.29 for producer and FPS, respectively. In case of cattle holdings, fodder farmers reared more cross-bred cattle than the local cattle. The highest numbercross-bred cattle (22.95/ farm) were reared by producer in Dinajpur district,whereas FPSreared 9.88 cattle per farm in Jessore district.The production cost of fodder for producer was estimated the highest (Tk 1,87,598/ha) in Kurigram district and the lowest (Tk 1,71,883/ha) for FPS in Kurigram district. The bio-mass yield was the highest (214.05 t/ha) for producer in Dinajpur district and the lowest was (201.45 t/ha) for FPS in kurigram district. Annual net return from fodder production was estimated the highest (Tk 2,12,272/ha) for FPS in Jessore district and the lowest (Tk 1,29,806/ha) for FPS in Kurigram district. The BCR was the highest 2.18 for FPS in Jessore district and the lowest was 1.75 for FPS in Kurigram district. Problems faced by the fodder farmers were lack of HYV fodder species, lack of knowledge, and lack of input facilities. The study suggested supply of HYV fodder, provide training on fodder cultivation and preservation, availability of more milk producing cattle breed in fodder production areas.

Published: May 2020

This study was conducted to know the production performance of laying hen by using different graded level of linseed. At 56 weeks of age, a total of 160 laying hens were raised up to 63 weeks of age. All hens were fed a basal corn soyabean meal diet. The experiment was allowed 4 dietary treatments (T0, no addition of whole linseed in the basal diet; T1,  addition of 5% whole linseed; T2, addition of 10% whole linseed and T3, addition of 15% whole linseed) with 5 replications and per replication contains eight hens. Egg production, feed intake, egg weight of each treatment was recorded. Egg samples were collected and analyzed for egg quality. The results showed that egg production and egg mass (kg) exhibited for all dietary treatment groups were unaffected (P>0.05) by feeding linseed to the laying hens. Feed Conversion Ratio (FCR) was found significant difference within the four dietary group (P<0.05). Egg quality aspects such as yolk weight, egg weight, HU and yolk index were not differed significantly (P>0.05) among treatments.  A trend for lower yolk weight was observed in birds fed 10% linseed, where as the highest yolk weight percentage was recorded in control diet. There was no statistical difference among the different diets for yolk index. The results of the present trial suggested that feeding linseed to the laying hens has no detrimental effects on egg production and egg quality.

Effect of exogenous Phytase on Egg Production and Egg Quality of Spent Hen
Authors: Bashar MK , Howlider MAR , Bulbul SM
Published: May 2020

The present study determined, assessed and quantified the exogenous phytase on egg production and egg quality of spent hens. Ninety laying hens (ISA- Brown) received iso-energetic and iso-nitrogenous diet supplemented with 0, 0.05, 0.1, 0.15 and 0.2 % phytase and reared in cages. Each layer was fed 120g feed/day from 90 to 100 weeks of age. At the inception of the study the spent hen at the age of 90 weeks had an average egg production 65.21 %. Phytase addition in diet increased (p<0.05) egg production  (7.67, 12.17, 12.04 and 15.87 % higher than control group), egg mass output (5.5, 9.34, 7.65 and 12.72 % higher than that of control) and feed conversion, but it did not alter shell weight, shell thickness, shape index, albumen index, Haugh unit, per cent yolk and yolk color. It was concluded that reduced egg production of spent hen at older ages to some extent might have a relationship to decreased availability of phosphorus. The decreased egg production in hens at older ages could be corrected by adding appropriate phytase level in the diet. Thus, it may be possible to extend and prolonged productive life of spent hens by supplying exogenous phytase in diet. However, the effect of availability of phosphorus on egg production using larger population for a longer period may be performed to confirm the findings of the current study.

With a view to increase the productivity of existing backyard livestock and poultry production systems and thereby to improve the socio-economic status of the rural people, BLRI in collaboration with the Department of Livestock Services (DLS) initiated the study since April 2010. The specific objectives of the study were to disseminate the livestock technologies for increasing productivity through training and demonstration and to assess the impact of technological interventions on livestock productivity, socioeconomic improvement and changing livelihood status of rural farm families. The study was implemented initially at Kadamtoli under Belkuchi  Upazila under Serajganj district and Chakpara and Bichamara villages under Naikhongchari Upazila under Banderban district which was later extended to Talukhabu village of Gongachara Upazila under  Rangpur district. Through this project, technological support was provided to a total of 321, 218 and 780 farm households in Belkuchi, Naikhongchari and Gangachara upazila, respectively. In order to conduct the impact study, 90 farmers taking 30 from each Upazila were selected through simple random sampling technique. The ‘before’ and ‘after’ comparison was followed for assessing the impact. The t-statistic was applied to test the significance of relevant parameters. It was revealed that technological intervention has resulted to increase in livestock and poultry population and increase in productivity of milk (19-40%), duck and chicken eggs (22-36%) both horizontally and vertically. There was no occurrence of death of cattle, goat and poultry birds. Farmer’s overall income was boosted up which has contributed to possession of new household assets and addition of the already available assets. The consumption of all food items was increased as well. It was recommended that the programme may be replicated to other locations with new interventions.

Published: May 2020

An on-station study was conducted at demonstration farm of Rural Development Academy (RDA) Bogra, Bangladesh with objectives to determine the impact of multilayer (two storied) cattle farming on food security for achieving economical and environmental sustainability. A two storied shed for cattle rearing were built with 10:1 slope for easy drainage and disposal of urine, faeces, wash water, feed refusals to a biogas plant directly for anaerobic digestion. About 70-80% waste materials was automatically and the rest amount was transferred manually. Per annum total waste 787.67 tons was used and produced 28356 m3 biogas and 157.53 tons of organic manure. Gross return of Tk. 24,61,272 and gross profit of Tk. 1145672 was made on a capital investment for Tk. 13,15,600. The benefit cost ratio (BCR) found 1:1.87. Compared to conventional, multilayer farming significantly higher amount of fresh manure was collected. In conventional farming, on an average 39.4% of manure is lost due to rain and flood caused contamination of water and threat to public health. The analysis of per day income from a cow was significantly (p<0.01) higher in multilayer farming system compare to conventional system. The average income from manure was Tk. 24.14 and Tk. 4.62/cow, respectively. Thus, it may be concluded that multilayer cattle farming may be more profitable and effective for waste processing, reduction of pollution and sustainable development of environment.

A number of indigenous plants actively used for therapeutic purpose in Bangladesh. The research work was conducted to investigate the effects of indigenous medicinal plants, Dad Mardan (Cassia alata) and Ata (Annona reticulata) against skin diseases (ringworm, scabies, dermatitis, wounds) in calves. The protective efficacy was observed by the topical application of the 10% combined ointment (Dad Mardan and Ata leaves) and 20% Dad Mardan ointment twice daily on nine calves having skin lesions. Calves treated with combined ointment were almost cured at 21st day of post-treatment whereas calves treated with Dad Mardan ointment were completely healed up after 24th day of post-treatment with the formation of scar tissue and growth of new of hair around the scar tissue and the healing rate was 99.73 % & 99.64 %, respectively. The skin lesions of untreated calves were aggravated with time (5.51% lesion area increased at 24th day from the first inspection). The combined ointment showed the more effectiveness (99.73% healing at 21st days) than the dad mardan ointment (93.76% healing at 21st days) against skin lesions. It may be concluded the ointments of Dad Mardan and Ata leaves can be used as alternative drugs for the treatment of skin diseases in calves.

Graduation is a target that must be achieved by students, especially graduating on time will be very important. To determine students who graduate on time or cannot be determined before students reach the final semester and hold a trial, many students who fail to graduate on time cause delays and affect the quality assurance of a tertiary institution. The problem in this research is how to optimize student graduation in order to graduate on time. Therefore, to determine this decision, we conducted a graduation data trial using the SVM method with GA optimization. SVM with accurate learning skills and good generalizations in classifying non-linear data, but SVM is weak in terms of parameter optimization it requires optimization using GA. GA is a method that has evolved to produce a more optimal data. From the results of processing using SVM and GA, we get more optimal results with 86.57%. Then from these results can help students to graduate on time.

Coronavirus Disease 2019 (COVID-19) has become a pandemic in Indonesia as a non-natural disaster in the form of disease outbreaks which must be undertaken as a response. The Ministry of Health in the Republic of Indonesia published a guidebook for prevention and control of COVID-19 in its response efforts. This guideline is intended for health officials as a reference in preparing for COVID-19. This handbook contains early detection and response activities to identify conditions of PDP, ODP, OTG, or confirmed cases of COVID-19. The efforts made are adjusted to the world situation progress from COVID-19 which is monitored by the World Health Organization (WHO). From the results of documentation studies that have been carried out on the COVID-19 pandemic in Indonesia, there are several problems that must be resolved from the prevention of the disease outbreak COVID-19. Lack of knowledge and awareness of the general public in the prevention and control of COVID-19 is one of the factors increasing the spread of that virus in Indonesia. Furthermore, there are difficulties in carrying out surveillance, early detection, contact tracing, infection prevention or control, and risk communication or people empowerment. This is due to the lack of implementation and testing on artificial intelligence methods for COVID-19 diagnosis that can be used by the public. The purpose of this research is to make a diagnosis of surveillance classification which includes PDP, ODP, and OTG using the C4.5 algorithm. The results showed that the diagnosis of the COVID-19 surveillance category using the C4.5 algorithm was successfully modeled into a decision tree with PDP, ODP, and OTG classification. The testing process in a confusion matrix with 3 (three) classes produces an accuracy rate of 92.86% which is included in the excellent classification category.

Pandemics and Political Development: The Electoral Legacy of the Black Death in Germany
Authors: Gingerich Daniel , Vogler Jan
Published: May 2020

Do pandemics have lasting consequences for political behavior? We address this question by examining the consequences of the most deadly pandemic of the last millennium: the Black Death (1347-1351). Our claim is that pandemics can influence politics in the long run if they impose sufficient loss of life so as to augment the price of labor relative to other factors of production. When this occurs, labor repressive regimes (such as serfdom) become untenable, which ultimately leads to the development of proto-democratic institutions and associated political cultures that shape modalities of political engagement for generations. We test our theory by tracing out the local consequences of the Black Death in German-speaking Central Europe. We find that areas hit hardest by the pandemic were more likely to: (1) adopt inclusive political institutions and equitable land ownership patterns; (2)exhibit electoral behavior indicating independence from landed elite influence during the transition to mass politics.
Systems of Innovation and Economic Theory
Authors: Scerri Mario
Published: May 2020

The volume of literature which emerged around innovation and systems of innovation in the 1980s and the first half of the 1990s held the promise of the emergence of an account of the general economy which could challenge the mainstream. The central argument of this paper is that the failure of that promise to materialise was due to the identification of neoclassical economics as the mainstream against which the system of innovation approach would be counterpoised, rather than neoliberal economics. While the former constitutes the disciplinary base of mainstream economics, the latter has formed its discourse. This paper looks at the contradictions between discipline and discourse in the mainstream and the relegation of the economic understanding of innovation to a peripheral area of study within economics.

Pistachio nuts are worldwide appreciated for their chemical and organoleptic profiles. There are several studies on the influence of irrigation on pistachio productivity, whereas there are little available data on the influence on nut quality. In this study we characterized some qualitative traits of pistachio nuts cultivar Bianca in Mediterranean environment and how plant water status affected them. Water status had a positive and significant influence on the chlorophylls content, nuts from less stressed trees showed higher values of chlorophyll a (14.7 mg/100 g) and b (21.1 mg/100 g) compared than more stressed trees (9.3 and 11.5 mg/100 g for a and b, respectively). Solid phase microextraction technique in headspace followed by gas chromatography/mass spectrometry (HS-SPME GC/MS) identified seventeen different compounds with terpenes being the major class of volatiles; the most abundant were α-Pinene (range 26.2–35 μg/g), D-Limonene (2.8–3.3 μg/g), 2-Carene (1.8–3 μg/g) and β-Myrcene (0.6–1.4 μg/g). Overall, we found higher level of terpenes in less stressed trees and for α-Pinene and β-Myrcene differences were significant. The fatty acid composition analysis revealed oleic acid (70.1–71.1%), linoleic acid (13.5–14.4%) and palmitic acid (9.6–9.8%) as the most abundant compounds, but tree water status did not influence their concentration. Overall, the data reported proved that supplemental irrigation contributes to increase pistachio nut quality.

Chamomile is a herbal plant of very high economic importance worldwide. Its organically grown raw material is particularly valuable. Under organic farming conditions, weeds and fungal diseases are an important problem in a chamomile plantation. Seeking agronomic solutions designed to eliminate the occurrence of these pathogens in chamomile crops is constantly valid. The aim of the present study was to evaluate the effect of some foliar sprays (enhancing the condition of the crop plant and its competition against pathogens) and different row spacing of two chamomile cultivars on weed infestation and health of a chamomile plantation. The study results presented in this paper were collected from field experiments carried out in the organic system in the village of Dys (the central Lublin region, Poland) over the period 2014–2016. Experiments were conducted on podzolic soil (class III) as a split-block design in 3 replicates in plots with an area of 525 m2 (6.25 m2 a single plot). This study included two chamomile cultivars (“Złoty Łan”, “Mastar”). The second experimental factor was single or double foliar application of three bioproducts (Herbagreen Basic, Bio-algeen, Effective Microorganisms—EM Farming). The other experimental factor was a different row spacing of chamomile (40 cm and 30 cm). The obtained study results show that 10–16 annual weed species and 1–3 perennial species occurred in both chamomile cultivars. Foliar application of the bioproducts contributed to a reduction in the total number of weeds in the crop, but at the same time to greater weed species diversity. In the control treatments (without the bioproducts), the dominance of several weed species (Viola arvensis, Galeopsis tetrahit, Spergula arvensis, Juncus bufonius, Scleranthus annuus) and lower biodiversity of the weed flora were observed. The largest reduction (by about 20%) in the number of annual weeds was found under the influence of the bioproducts Herbagreen Basic and Bio-algeen applied once. Bio-algeen and Effective Microorganisms (EM), in turn, had a significant effect on decreasing the weed weight. A narrower (30 cm) row spacing of chamomile had a significant impact on reducing the weight of weeds in chamomile crops compared to the wider spacing, which was 40 cm. It should be concluded that infection of the chamomile plantation with fungal diseases was overall at a low level. Significantly higher infection with fungal diseases was found in the case of the cultivar “Mastar”, regardless of the experimental factors. A statistically proven decrease in infection of chamomile plants with fungal diseases was determined under lower crop density conditions (a row spacing of 40 cm). Chamomile plants were found to exhibit better health under the influence of double application of the biofertilizers Herbagreen Basic and Bio-algeen.

Vine growing and wine production is gaining in popularity around the Baltic Sea Region. The first aim of the experiment was to determine the variability of the total phenolic and anthocyanin content (from 2010 to 2018) and of individual anthocyanin content (from 2016 to 2018) in the hybrid grape cultivars ‘Hasansky Sladky’, ‘Zilga’, and ‘Rondo’. In field conditions ‘Rondo’ had winter cold damage to canes in two years. Therefore, the second aim was to determine the effect of high polyethylene tunnel and field conditions on fruit total and individual anthocyanin content of ‘Rondo’ from 2016 to 2018. Over nine years, the total phenolic content ranged from 192 to 671 mg 100 g−1 and anthocyanins from 30 to 405 mg 100 g−1 spectrophotometrically. The anthocyanin (delphinidin-3-O-glucoside, cyanidin-3-O-glucoside, petunidin-3-O-glucoside, peonidin-3-O-glucoside, malvidin-3-O-glucoside) content depended on cultivar properties and climatic parameters. Antioxidant activity was cultivar dependent and ranged from 40 to 88%. Polytunnel cultivation increased the content of total anthocyanins in ‘Rondo’ from 447 to 1472 mg 100 g−1 (by chromatographically) in cooler year, but in warmer years it decreased from 3645 to 1618 mg 100 g−1. Individual anthocyanins showed the same tendency. Grapevine cultivar ‘Rondo’ is recommended for tunnel growing in very cool climate conditions.
Understanding the Redox Biology of Selenium in the Search of Targeted Cancer Therapies

Published: May 2020

Selenium (Se) is an essential trace nutrient required for optimal human health. It has long been suggested that selenium has anti-cancer properties. However, clinical trials have shown inconclusive results on the potential of Se to prevent cancer. The suggested role of Se in the prevention of cancer is centered around its role as an antioxidant. Recently, the potential of selenium as a drug rather than a supplement has been uncovered. Selenium compounds can generate reactive oxygen species that could enhance the treatment of cancer. Transformed cells have high oxidative distress. As normal cells have a greater capacity to meet oxidative challenges than tumor cells, increasing the flux of oxidants with high dose selenium treatment could result in cancer-specific cell killing. If the availability of Se is limited, supplementation of Se can increase the expression and activities of Se-dependent proteins and enzymes. In cell culture, selenium deficiency is often overlooked. We review the importance of achieving normal selenium biology and how Se deficiency can lead to adverse effects. We examine the vital role of selenium in the prevention and treatment of cancer. Finally, we examine the properties of Se-compounds to better understand how each can be used to address different research questions.

Published: May 2020

The general spread of Tribulus terrestris L. (South Africa, Australia, Europe, and India), the high content of active ingredients (in particular sterol saponins, as well as flavonoids, tannins, terpenoids, phenol carboxylic acids, and alkaloids), and its frequent uses in folk medicine, and as food supplements highlight the importance of evaluating its phytopharmacological properties. There are miscellaneous hypotheses that the species could have a high potential for the prevention and improvement of various human conditions such as infertility, low sexual desire, diabetes, and inflammatory diseases. Worldwide, numerous herbal supplements are commercialized with indications mostly to improve libido, sexual performance in both sexes, and athletic performance. Phytochemical studies have shown great disparities in the content of active substances (in particular the concentration of furostanol and spirostanol saponoside, considered to be the predominant active ingredients related to the therapeutic action). Thus, studies of experimental pharmacology (in vitro studies and animal models in vivo) and clinical pharmacology (efficacy and safety clinical trials) have sometimes led to divergent results; moreover, the presumed pharmacodynamic mechanisms have yet to be confirmed by molecular biology studies. Given the differences observed in the composition, the plant organ used to obtain the extract, the need for selective extraction methods which are targeted at the class of phytocompounds, and the standardization of T. terrestris extracts is an absolute necessity. This review aims to highlight the phytochemical, pharmacological, and toxicological properties of T. terrestris, with a focus on the contradictory results obtained by the studies conducted worldwide.
Structure of the Hydrophobic Core Determines the 3D Protein Structure—Verification by Single Mutation Proteins

Published: May 2020

Four de novo proteins differing in single mutation positions, with a chain length of 56 amino acids, represent diverse 3D structures: monomeric 3α and 4β + α folds. The reason for this diversity is seen in the different structure of the hydrophobic core as a result of synergy leading to the generation of a system in which the polypeptide chain as a whole participates. On the basis of the fuzzy oil drop model, where the structure of the hydrophobic core is expressed by means of the hydrophobic distribution function in the form of a 3D Gaussian distribution, it has been shown that the composition of the hydrophobic core in these two structural forms is different. In addition, the use of a model to determine the structure of the early intermediate in the folding process allows to indicate differences in the polypeptide chain geometry, which, combined with the construction of a common hydrophobic nucleus as an effect of specific synergy, may indicate the reason for the diversity of the folding process of the polypeptide chain. The results indicate the need to take into account the presence of an external force field originating from the water environment and that its active impact on the formation of a hydrophobic core whose participation in the stabilization of the tertiary structure is fundamental.
