Authors: PANWAR A S
Published: August 2023

A field experiment was conducted during 2009â€“12 at ICAR Research Complex for NEH Region, Umiam, Meghalaya to study the performance of congosignal grass (Brachiaria rosensis L) under silvi-pastoral based agroforestry system in mid hill altitude of North East India. Congosignal grass was planted in open as well as intercrop with Simingtonia populanea and fertilized with 0, 30, 60 and 90 kg N/ha. The study showed that growth attributes and yield of congosignal was reduced under tee canopy, while crude protein content was 5.35 % higher under tree canopy. Dry fodder production was significantly higher in open (119.55 q/ha) than under tree canopy (87.46 q/ha). The content and uptake of NPK by congosignal grass were higher in open area, while organic carbon and residual NPK status improved under tree canopy. Application of nitrogen at increased level improved plant height, no. of tillers and leaf:stem ratio. The green and dry biomass yield was significantly higher with 60 kg N/ha. The content and uptake as well as residual NPK were significantly improved with 60 kg N/ha. The soil organic carbon improved under tree canopy than open. Higher gross and net return were recorded with application of 90 and 60 kg N/ha in open and tree canopy, respectively. The B:C ratio (3.08) was higher with 90 kg N/ha in open planting, while under tree canopy highest B:C ratio of 2.19 was recorded with 60 kg N/ha.

Published: August 2023

Rice fallows (RF) are the low lying kharif sown rice (Oryza sativa L.) areas that remain uncropped due to dearth of suitable cultivars of winter (rabi) pulses. A panel of 30 promising high yielding lentil (Lens culinaris Medik.) genotypes of diverse origin were assessed at both no till RF and with till condition at the Regional Research Substation (RRSS), Chakdah under the aegis of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal for two years (2019–20 and 2020–21). Multi-trait performance (earliness, biomass and grain yield) of each genotype was considered during recommendation of suitable genotype for specific ecology deploying GGE biplot. The presentstudy recommended IC 560183 for no till RF ecology and Moitree, IC 559996, ILL 7978 and L 1112-19 for with till ecology having specific adaptation. Additionally, 2011S-56212-2 and ILL 8006 were identified as ideal and desirable genotypes for both the ecologies and therefore, recommended for commercial cultivation across the areas of Gangetic alluvial zone for augmenting lentil production and productivity.

Published: August 2023

One of the most economically viable processes for the bioconversion of many types of lignocellulosic wastes is represented by edible mushroom cultivation. Pleurotus florida is one of the prominent economically cultivated mushrooms with varied abilities to utilize lignocellulose as a growth substrate. Thus, the profile of oxidative and hydrolytic enzymes was measured during the submerged and solid-state fermentation at Punjab Agricultural University, Ludhiana, Punjab during the winter (rabi) season of the year 2020–21. The intracellular activity of laccase (10.23 IU/mg), manganese peroxidase (9.98 IU/mg), cellobiohydrolase (5.46 IU/mg) was best obtained in P. florida on the 14th day. The extracellular activity of laccase (15.43 IU/ml), lignin peroxidase (11.21 IU/ml), endoxylanases (9.22 IU/ml)were found to be highest on the 14th day. P. florida had substantial levels of ligninolytic enzymes during substrate colonization but rapidly diminished during fruit body development. On the other hand, P. florida showed relatively low hydrolase activity during substrate colonization. The activity of these enzymes increased when primordia formed. The hydrolytic activities peaked at the mature fruiting body stage. When mushrooms switched to vegetative development, ligninolytic enzyme activity increased again, while hydrolase activity declined. The yield was found to be 58.78% after the enzymatic treatment of paddy straw. These findings suggest that fluctuations in oxidative and hydrolytic enzyme activities are linked to the growth of the fruiting body and the physiological state of mushroom cultivation.

Authors: SHARMA VIKAS , SINGH P K
Published: August 2023

The present study was carried out at Technology Park of College of Technology and Engineering, Udaipur, Rajasthan for two years (2019 and 2020) with 6 irrigation treatments and four replications in RBD. Among all the treatments, the treatment T2 (Irrigation at 85% field capacity of soil, based on soil moisture sensor based drip irrigation system) was found best in selected areas for growing okra [Abelmoschus esculentus (L.) Moench] crop under sensor based drip irrigation with maximum crop yield and biomass. In other water scarce regions of Rajasthan, the use of a simulation model can be a better option to predict the crop yield and biomass with respect to different irrigation levels. Therefore, calibration and validation of the AquaCrop model was done with the help of various data which were collected from field experiments during the study period (2019–20). The cut off temperature and base temperaturewere set as 32.5–100C, respectively. The model was successfully calibrated and validated with minimum prediction error, mean absolute error (MAE: 0.34–0.56), root mean square error (RMSE: 0.38–0.60) and maximum model efficiency (E ranges 0.8–0.95) and coefficient of correlation (R2 > 0.9). The overall result indicate good performance of the model and can help in decision making as well as for irrigation water management for okra crop under the given conditions of Udaipur district of Rajasthan. It can be used to assess the influence of various environmental factors and management practices on okra crop growth.

Published: August 2023

A 8-parent diallel analysis was taken to investigate the genetic effects and heterosis for seed yield and 6 physiobiochemical characters in chickpea (Cicer arietinum L.) under timely and late sown conditions at research farm of Rajasthan Agricultural Research Institute, Durgapura, Jaipur, Rajasthan during winter (rabi) seasons of 2020–21 and 2021–22. Significant disproportion of GCA and SCA variances depicted that both additive and non-additive gene action plays a vital role for genetic control of all the traits. Though the relative amount of GCA/SCA was less than unity for all traits under study signifying that non-additive gene plays a key role under the environments studied. The parents CSJ-515, CSJD-884 and RSG-963 emerged as good general combiners for seed yield, additionally theparents CSJ 515 and RSG 963 were considered as good general combiners for CC and PV, whereas parent CSJD-884 for MSI, TCC and PC. The crosses CSJD 884 × RSG 963, CSJD 884 × RSG 973, CSJD 884 × Avrodhi, CSJD 884 × HC 5, RSG 963 × CSJ 515, RSG 974 × HC 5 and CSJ 515 × HC 5 showed consistent SCA effect and heterobeltiosis for seed yield and one or more heat tolerant physio-biochemical traits and projected that these crosses would provide enviable transgressive segregate for heat tolerance.

Published: August 2023

A two year (2021 and 2022) field experiment was conducted to study the effect of organic amendments on soil microbial activity and yield of faba bean (Vicia faba L.) inoculated with Rhizobium leguminosarum at Savadkuh in the north of Iran as a factorial experiment based on a randomized complete block design with 3 replications. The treatments included seed inoculation at two levels (inoculation with Rhizobium leguminosarum bv. Viciae and non-inoculation) and fertilization at 5 levels [cattle manure (CM) @30 tonnes/ha, vermicompost of manure (VM) @20 tonnes/ha, vermicompost of Azolla (VA) @20 tonnes/ha, chemical fertilization based on soil analysis (NP), and control]. Present study found that the soil microbial biomass carbon (C) increased over time until 120 daysafter emergence (DAE). The maximum microbial biomass-C (441 mg/g soil) and bacterial count (545 × 105 cfu/ml) were obtained from the inoculated VA treatment. The highest yields of pods (14400 kg/ha) and seeds (1266 kg/ha) were obtained when the use of vermicompost was accompanied by inoculation of R. leguminosarum, so that in plants without inoculation, the use of vermicompost increased the yield of pods compared to the NP by 34% and compared to CM, it increased by 44%, but this increase was 39% and 19% for inoculated plants compared to NP and CM, respectively. Although the seeds of vermicomposted plants showed lower iron (Fe) content, they showed higher nitrogen (N), phosphorus (P), copper (Cu) and zinc (Zn) content than other plants. In total, the results showed a significant improvement in soil microbial activity, absorption of nutrients and bean yield by using vermicompost(especially VA) under R. leguminosarum inoculation. Therefore, in the low-fertile soils of Iran, the combined use of high-quality vermicompost together with R. leguminosarum can strengthen soil microbial activity and bean production and be a suitable alternative to chemical fertilizers.

Published: August 2023

Despite many studies reporting conservation agriculture (CA) impacts on soil organic carbon (SOC) sequestration, the impacts of long-term permanent bed planting under CA on SOC sequestration are rarely reported. Hence, this study assessed the permanent bed planted CA impacts on SOC sequestration rates in 0–30 and 30–60 cm soil depths under a cotton (Gossypium hirsutum L.)-wheat (Triticum aestivum L.) system in the Indo-Gangetic Plains (IGP). The treatments comprised diverse combinations of tillage and residue retention (R), viz. conventional tillage (CT), narrow bed, narrow bed + R, broad bed, broad bed + R, flat bed + R and flat bed. Results indicated that the total SOC stock was ~32, 31 and 29% higher in CA plots than in CT plots (farmers' practice), in 0–30 cm soil depth. The SOC sequestration rate (over CT plots) in the CA plots was ~0.76 Mg C/ha/yr. The broad bed + R, narrow bed + R and flat bed + R plots had appreciably high total SOC sequestration (~0.24 Mg C/ha/yr) compared to CT plots in deep soil layer (30–60 cm). The yield data (2-year mean basis) was recorded highest in the broad bed + R (3.48 tonnes/ha and 8.11 tonnes/ha for cotton and wheat, respectively) and flat bed + R (3.38 tonnes/ha and 8.46 tonnes/ha for cotton and wheat, respectively) treatments showing a positive impact of the adoption of long-term CA in the IGP. Thus, adopting raised beds with residue retention has great potential for higher carbon sequestration and improving yields and can be recommended for sustainable intensification of arable lands in the region.

Published: August 2023

The Pasaman earthquake which occurred on 25 February 2022, with a magnitude of 6.2, caused casualties and infrastructure damage. Vulnerability identification determines the potential extent to which a system or unit tends to be damaged. Vulnerability identification in this study was carried out based on four vulnerability indicators, namely: rate of soil movement from satellite image processing, soil type classification based on Vs30, corrected isoseismal shakemap, and residential area maps. Each indicator, with their respective weightage, is then scored and summed to evaluate the vulnerability of areas in the vicinity of Pasaman earthquake. The processing of Sentinel-1 SLC satellite data using the advanced Differential Interferometric Synthetic Aperture Radar (DInSAR) produces a deformation rate around area of epicenter. Areas that have high vulnerability generally have a value of ground movement rate in the form of subsidence above 5 cm/year. These areas were predominantly residential and experienced significant damage during the earthquake. The soil type in these regions was classified as medium soil, and the intensity of shocks during the earthquake was categorized as VI MMI or higher. This study was conducted in the area near the epicenter of the Pasaman earthquake, such as in the district Pasaman, Bonjol, Pasaman, Palembaya, and Lubuk Basung. A study of disaster vulnerability identification is carried out to reduce the losses and minimizing the exposure of the population to disasters. The results of vulnerability identification can be used as part of education and literacy to reduce the risk of earthquake disasters.

Published: August 2023

Tomato contains large amount of water which makes it more susceptible to spoilage by fungi. The fungi responsible for the tomatoes spoilage, produce mycotoxins that are detrimental to human health. The sample from Mile 1 market had highest colony count of Mucur spp. The phytochemical study of the tomato extracts both revealed that phenol had the highest occurrence 30.25±1.35 & 22.2±1.60 and tannin lowest 2.83±0.73& 0.24±0.12. Bioactive compounds stored in plant possess biological and antibacterial activities that can be used as an alternative medicine for the treatment of bacterial infections in man. These compounds have been reported to bestow resistance in opposition to microbial pathogens and this could be accountable for the exhibition of antibacterial activity by both extracts in this present study.

Signaling Channels of Financial Service Digitalization for Financial Inclusion in Nigeria
Authors: Ozigbu Johnbosco Chukwuma , Ezekwe Christopher Ifeanyi
Published: August 2023

Drawing support from the technology diffusion theory and technology acceptance model, this study examined how financial service digitalization contributed to the process of financial inclusion in Nigeria. Three financial technologies, POS, ATM, and web payment services, were selected based on their dominance and availability to numerous bank customers in various locations, including rural areas. On the other hand, financial inclusion was measured by access to financial services, with a focus on the number of bank branches across Nigeria. An ex -post facto research design was followed with the application of the autoregressive distributed lag (ARDL) model to analyse the quarterly data obtained from the Central Bank of Nigeria (CBN) Statistical Bulletin. The findings showed that the POS and web payment services increased access to financial services and, in so doing, reduced the number of bank branches. This finding suggests that the availability of POS and web payment services is a prerequisite for financial inclusion while abridging the cost of banking transactions. In addition, it was found that ATM service is significant in promoting access to financial services. The implication of this finding is that increased availability of ATM service is associated with an increase in the number of bank branches, as most banks tend to situate their ATM galleries in their various branches for security and cost-effectiveness. In light of the findings, it is concluded that ATM technology is the most outstanding channel of finance service digitalization for financial inclusion in Nigeria. Thus, it is recommended that deposit money banks prioritise the provision of financial technology, especially ATMs, while scaling up their operational efficiency to create more opportunities for financial inclusion in Nigeria

Published: August 2023

The production environment in which animals are kept can be classified by bioclimatic indexes expressing the conditions of thermal comfort to different species. In the state of Maranhão (MA), located in Northeast Brazil region, stand out in the livestock sector the beef cattle, pig and poultry production. In order to check the conditions of thermal comfort in the state for these species was held a bioclimatic zoning, taking into account the temperature and humidity index (THI) and Black Globe Temperature and Humidity Index (BGTHI). Estimates of the indexes were performed from meteorological data obtained from the database of the National Institute of Meteorology (INMET). Seven county were considered, and were chosen taking into account the greater amount of information available over the years. The variables analyzed were: air temperature, relative humidity and atmospheric pressure. Bioclimatic indexes were determined by using mathematical equations applied in Microsoft Excel®. Using the Surfer 8.0® program, were generated maps with bioclimatic zones to the state. Taking into consideration the comfort levels recommended as safe for poultry, pigs and cattle in all stages of production (THI 70-74 and BGTHI 72-75), the analyzed bioclimatic zones showed no conditions for comfort and optimal performance of these species, considering that the THI ranged from 74.1 to 75.8. and BGTHI from 80.0 to 82.3. Can be concluded that in the cities checked, the production systems of these species need investment in measures to promote the correction of microclimate to establish optimal levels of animals thermal comfort.

The present research contributes to the efficient nutrient management to pastures, and to the efficient use of cutting grasses in animal feed. In order to evaluate the productive performance of four genotypes of grass of genus Pennisetum (Common Elephant; King grass; Camerún; y Maralfalfa.) and the effect of N, P, K, Ca, Mg and S fertilization, an experiment was conducted on the experimental farm "El Oasis", from the Universidad Tecnológica Equinoccial. The design was used were random blocks with factorial accordance of the genotypes of grass (factor A) and fertilization (factor B) treatments. The variables that were analyzed were: total dry matter (MSt), partial factor productivity (FPP), leaf-stem relationship and age of cutting. The Common Elephant grass presented the highest production of MSt and MS of stems with 14.8 and 9.0 t ha-1, respectively (P < 0.05). The fertilization without N presented the lowest yields (P < 0.05) of MSt. Common Elephant and King grass showed the highest and the lowest FPP, respectively (P < 0.05). There were no differences (P > 0.05) due to the omission of nutrients in the leaf:stem relationship in the dry plant. The fertilization without Mg and the complete underground fertilization, each one showed the highest reduction (P < 0.05) on production of MS stems in the 120 d sampling. It is concluded that Common Elephant was the genotype least affected by the omission of nutrients in the accumulated production of MS and FPP.

Small-grain cereals are promoted as forage alternatives that may substitute for other traditional crops when short cycle forages are required for cattle feeding. The objective of the work was to assess in vitro the nutritive quality, ruminal fermentation kinetics and digestibility by the gas production technique of forage from common oat (Avena sativa cv. Canadiense) = AC, black oat (Avena strigosa cv. Saia) = AN, Triticale (×Triticosecale Wittm. cv. Criollo) = T, and rye (Secale cereale of national production) = C. The forage crops were sown in 250 m2 plots, harvested and sampled 72 days after sowing in a completely randomised design with five replicates. Both oat species (AC and AN) had significantly higher crude protein and neutral detergent fibre contents (P<0.05) compared to T and C. In vitro gas production showed a higher fermentation rate for black oat and common oat, with no differences for in vitro digestibility (P>0.05) for the evaluated forages. There were also no differences in the estimated ME content (P>0.05). Results indicate that black and common oats are forages with a better nutritive quality when harvested at a similar time compared to triticale and rye forage.

Published: August 2023

The diamondback moth (Plutella xylostella L.) is an insect that causes great losses in Brassica plantations, which may reach 100% loss in some cases. The most common method to control this pest is still the use of insecticide. However, its successive and arbitrary use has contributed to the development of insecticide resistance, and the study of alternative methods has become essential to successfully control the diamondback moth in broccoli. The objective of this study was to select isolates of rhizobacteria that act to control diamondback moth in broccoli. The experimental design was in randomized blocks, with three bacterial isolates [1 - Kluyvera ascorbata (EN4); 2 - Bacillus subtllis (R14); 3 - Bacillus cereus (C210) and 4 - Control (distilled water + spreader sticker)] tested with 5 repetitions in 20 m2 plots. Larval viability (LV), pupal viability (PV), larval stage duration (LD), pupal stage duration (PD), pupal weight (PW) and total mortality (TM) were evaluated. The rhizobacteria isolates performed better to reduce larval and pupal viability, larval and pupal duration, and increase total mortality, and can be used as a management option to complement the control strategies of the diamondback moth in broccoli.

The production of the CP-50 strain of Pleurotus ostreatus in water lily (Eichhornia crassipes) was evaluated in comparison and combination with some agricultural residues of the region Valsequillo, Puebla. The water lily was collected in the Manuel Ávila Camacho dam in the municipality of San Pedro Zacachimalpa to be used in the cultivation of the CP-50 strain under controlled conditions. An experimental random block design was carried out with a total of 240 production units. The highest biological efficiency (EB) is for the corn stubble treatment (136.6%) and the MLA treatment (120.6%), the lowest EB was for the LA treatment with 12.3%. The bromatological analyzes showed that the water lily can increase the crude protein content of the sporomes, where the highest percentage was obtained in the LA treatment with 32.6% and an energy value of 267.20 Kcal / 100 g. Additionally, it was demonstrated in the tests for heavy metals that the consumption of mushrooms grown on substrates supplemented with E. crassipes does not present food toxicity, since they comply with the parameters of the FAO Codex Alimentarium. The production of mushrooms was favored when using E. crassipes in agricultural residues such as barley straw and corn stubble, which represents an excellent option for the production of high protein food and for a more adequate management of aquatic lily within of the Manuel Ávila Camacho dam, Puebla.

The aim of this study was to describe the abundance, weight and body length structures, and reproductive and health status of the black rat Rattus rattus and the house mouse Mus musculus from Yucatán, México. Rodents were trapped from May to September 2016 in rural households in the communities Xkalakdzonot (XKA) and Paraíso (PAR). A total of 236 M. musculus and 127 R. rattus were trapped over 3880 trap-nights. In XKA, R. rattus was more abundant than M. musculus, whereas in PAR, M. musculus was notably dominant over R. rattus. The sex ratio was 1:1 in both rodent species. Rattus rattus in classes 40.1–80 g and 120–139 mm were more abundant, whereas M. musculus in classes 8.1–12 g and 70–79 mm were more abundant. Mus musculus had similar weight, body length and reproductive and health parameters between communities. The majority of specimens of trapped rodents had a good body condition and few individuals had wounds. The information generated in this study is basic for understanding the ecology of commensal rodents, the dynamics of rodent-associated zoonosis transmission, and to design of integrated control programs for rodents.

Published: August 2023

The effects of level of dried distillers grains with solubles (DDGS) and rice polishings (RP) on the scrotal circumference and semen parameters were examined in 22 crossbred (Pelibuey x Dorper) ram lambs (average live weight 24.84 ± 2.07 kg, approx. 5 months of age). The lambs were randomly allotted to four treatments in a 2 x 2 factorial design. The two factors were dietary levels of RP (0 and 15%) and of DDGS (0 and 30%). The experiment lasted 52 days. The animals were weighed on days 0, 34 and 52, and semen variables were measured on days 34 and 52. Semen evaluation included sperm morphology, mass and progressive motility, and sperm concentration. On day 34, sperm concentration showed an interaction of both effects (P=0.01) and was greater in rams in group 4 (both RP and DDGS) than in those in groups T2 (RP alone) or T3 (DDGS alone). Sperm morphology (% normal cells) was higher (main treatment effect) in rams fed with 30% DDGS than in those not fed with DDGS (P<0.05). The other variables showed no treatment effect. On day 52, none of the ejaculate variables varied with treatments. In conclusion, the diets did not affect body weight of ram lambs, but did affect the percentage of normal spermatozoa at 34 d of the trial, although this effect was not observed after 52 d of the trial; thus, in the long run, these diets do not alter scrotal circumference or semen parameters of young Pelibuey x Dorper ram lambs.

The disease known as "chickpea rabies", caused by Fusarium oxysporum, Fusarium solani and Rhizoctonia solani, is one of the main limitations of chickpea production in Mexico. Traditionally, chemical control has been used, which has negative impact on agroecosystems. Biological control is an ecological alternative for the management of plant diseases by the use of antagonistic bacteria and fungi. The objective of the present investigation was to isolate and identify rhizobacteria of chickpea plants with in vitro antagonistic capacity towards F. oxysporum, F. solani and R. solani and plant growth promotion. The ability of the isolates to produce siderophores, gibberellic acid and solubilize phosphorus was evaluated. Sixty-seven bacterial isolates were obtained, of which two (AG-B007 and AG-B038) were selected because of strong in vitro antagonism towards F. oxysporum, F. solani and R. solani. These isolates presented siderophore production in CAS medium, solubilization of inorganic phosphorus in ranges of 164 to 171 μg mL-1 and gibberellic acid in values of 29 to 55 μg mL-1. The inoculation of the AG-B007 and AG-B038 isolates promoted growth in chickpea plants under greenhouse conditions. The two isolates were identified as belonging to the genus Bacillus by sequencing the 16S RNAr gene.

In this study, the effect of two alternative growing substrates (corncob and Azolla anabaena) on some vegetative parameters (days to emergence, stem diameter, plant height and root volume) in seedlings of broccoli hybrid Coronado were evaluated. Both materials were ground and used according to the following treatments: 100% corncob (T1), 100% Azolla (T2), 50% corncob + Azolla 50% (T3), corncob 75% + Azolla 25% (T4), 25% corncob + Azolla 75% (T5) and then compared to a commercial substrate (BM2) (T6). Substrates were uniformly mixed, deposited in germination trays and watered at field capacity. Additionally, physic-chemical characteristics were determined in the different substrates used for broccoli seedling production. Stem diameter, height plant and root volume showed to be statistically higher in seedlings grown in commercial substrate (0.18 cm, 5.27 cm and 0.61 cm3, respectively) followed by those seedlings grown in 100% Azolla (0.17 cm, 4.92 cm and 0.49 cm3, respectively) (p< 0.001). Seedlings growing in substrates with higher corncob proportion showed lower values in these vegetative parameters. Based on our results, Azolla showed potential to be used as a seed substrate for production of broccoli seedlings, thus decreasing the use of peat and consequently the production costs in nurseries.

In this study, the acaricidal effect of leaf and seed extract doses from Annona cherimola (625, 1250, 2500, 5000 and 10000 mg/L) on mortality rate, oviposition rate and fecundity in O. coffeae females were evaluated under laboratory conditions. The effectiveness of extracts was evaluated using the residual contact technique in rearing units using coffee leaf discs. Mortality, oviposition and fecundity of O. coffeae females were affected by type and concentration of extract. Highest mortality rate was achieved with the application of seed extracts. Additionally, it caused oviposition decrease by 46.7 or 82.5% mainly with the seed extract at 625 and 10,000 mg/L, respectively, while the leaf extract, decreasing varied from 29.9 to 62.0% at the same concentrations. Seed extract was also more effective by reducing the fecundity of O. coffeae females (28.9 eggs/female), as compared to females treated with leaf extract (36.1 eggs/female). The results showed that cherimoya could be a sustainable alternative for the management of O. coffeae populations in coffee plantations, however field studies are suggested to validate laboratory studies.

The objective of this study was to evaluate the productive behavior in sows, as well as the hematochemical profiles and the incidence of diarrhea in piglets when using a microbial preparation fermented in byproducts of the agroindustry. We used 14 breeding sows, CC21 hybrids (Yorkshire - Landrace/L35 Duroc) and their offspring, divided into two groups: T1, Control and T2, microbial preparation A. T2, contained Lactobacilus acidophilus y Kluyveromyces fragilis L-4 (UCLV). The microbial additive was developed in a substrate composed of molasses, torula yeast and soy milk. 20 ml of microbial preparation were applied to the sows from the last third of gestation until weaning; and the piglets were supplied with 1 ml in mono dose for 2 weeks and subsequently increased to 1.5; 2 and 3 ml per animal respectively. A completely randomized design was used. The productive performance of sows and piglets was evaluated, such as weight gain, average daily gain, feed conversion, protein efficiency ratio, incidence of diarrhea and mortality, and blood profile and blood chemistry. With the use of microbial preparation weight gain, weight gain, average daily gain, feed conversion and protein efficiency ratio varied (P<0.05) between treatments, indices of diarrhea and mortality were lower (P <0.05) in T2. Blood profiles and blood biochemistry differed (P>0.05) between treatments (T1 and T2). In conclusion, the use of microbial preparation in the diet of pigs improves the productive parameters, decreases the incidence of diarrhea and blood profiles vary in some cases in the categories studied

Non-Specific Calibration Combined with Helium Collision Mode for Elemental Screening
Authors: McCurdy Ed , Riles Peter
Published: August 2023

Elemental analysis labs often measure only a small number of elements; for example, the U.S. Food and Drug Administration (FDA) Elemental Analysis Manual (EAM) regulatory method for food analysis by inductively coupled plasma-mass spectrometry (ICP-MS) (EAM 4.7) specifies only 12 trace elements. ICP-MS is a fast, multielement technique that can measure nearly every element in the periodic table and cover a concentration range from ultratrace to major elements. While labs rarely need to quantify all 75 or so elements that ICP-MS can measure, they may benefit from acquiring a more complete picture of the total elemental content of each sample. The amount of useful information that can be extracted from the ICP-MS mass spectrum is dramatically increased when helium (He) collision mode is used to minimize common spectral overlaps. Some ICP-MS instruments can perform a fast, He mode screening acquisition for each sample, combined with non-specific calibration to give semiquantitative concentrations for “all elements”. He mode screening gives access to confirmatory isotopes and detects elements that were not included in the quantitative analysis, providing valuable additional insight into each sample’s composition.

Published: August 2023

Background: Menstruation is a critical phenomenon in women’s life. However, variability in menstrual cycle characteristics and menstrual disorders are common. The purpose of this study was to determine the menstrual characteristics of females, its association with disorders and complications and overall female health.

Methods: The study was conducted to evaluate the menstruation disorders and common female complications and its severity in females and its effect on their regular activities. This is a cross-sectional study; conducted on 303 females in Darjeeling Himalayan region, structured questionnaires were used to gather the socio- demographic data, age at menarche, regularity in menses and dysfunctions. Data was analyzed using spss-16 and excel-2019.

Results: In the study mean age of menarche was found to be 12.94±1.69 year and menopause ages 45.4±6.45 years. Menarche and menopause age shows positive relation. The majority 59.1% (179) experienced dysmenorrhea, 33% menorrhagia, 22.1%(67) hypo menorrhagia followed byoligomerorrhea is 21.1% (64 females) and Polymenorrhea is 13.2% (40).(Fig: 2).Both early and late menarche was seen to be related to menstrual dysfunction among women. Menstrual disturbances were more prevalent among women who experienced menarche at a younger age and those with dieting habits. Consumption of alcohol, tobacco and junk food had negative impact leading to various menstrual disorders.

Conclusion: Menstrual problems among females are common and notions about female health are still in base. The study being the pilot project in this region seeks attention for help of females all around, for the education and educare of female child starting from education about periods to usage of right sanitary products, education about menstruation and its complications, importance of seeking help.
