Role of India's Anganwadi Center in Securing Food and Nutrition for Mothers and Children     

Sandhya Kumar  Rajesh Kumar Rai 《Journal Of Agricultural & Food Information》2013,14(2):174-182

India's 2013 National Food Security Act identifies Anganwadi centers (the courtyard shelter) as responsible for ensuring the food and nutrition for mothers and children. This article proposes four essential reforms that must take place to revitalize the languishing Anganwadi system: (a) strengthen implementation of the Integrated Child and Development Services (ICDS) through greater outreach and education; (b) boost incentives for Anganwadi workers and Anganwadi health workers; (c) bring together different government stakeholders to provide the integrative framework needed; and (d) improve monitoring and evaluation of Anganwadis so as to better gauge not just performance of workers, but also health and nutrition outcomes among women and children.  相似文献   

Application of Native Lactic Acid Bacteria (LAB) for Fermentative Recovery of Lipids and Proteins from Fish Processing Wastes: Bioactivities of Fermentation Products     

Amit Kumar Rai  R. Jini  H. C. Swapna  N. M. Sachindra  V. Baskaran 《Journal Of Aquatic Food Product Technology》2013,22(1):32-44

Fermentation using native lactic acid bacteria (LAB) was evaluated for its effectiveness in recovering lipids and proteins simultaneously from freshwater fish visceral waste (FVW). Five different LAB isolated from fish processing waste were employed in a fermentation process that involved 10% (w/w) glucose, 2% (w/w) NaCl, and 10% (v/w) LAB. Cultures evaluated included four native isolates (Pediococcus acidilactici NCIM5368, Enterococcus faecalis NCIM5367, Pediococcus acidilactici FM37, and Pediococcus acidilactici MW2) from FVW with E. faecium NCIM5335 as the reference culture. Fermentation with native LAB resulted in recovery of > 90% oil present in the material as against no recovery in case of raw (unfermented) viscera and resulted in > 50% of degree of hydrolysis of proteins. The fatty acid profile of lipids was not affected by the fermentation process. The fermentation liquor, rich in hydrolyzed protein, exhibited antioxidant as well as antagonistic properties against several bacterial pathogens. The results clearly demonstrate the usefulness of fermentation using native isolates for simultaneous recovery of lipids and proteins from fish processing waste. It also asserts the value of fermentation as an eco-friendly method and aids in minimizing disposal/pollution problems associated with these solid wastes.  相似文献   

Progression of molecular and phenotypic diversification in resynthesized Brassica juncea (L) gene pool with determinate inflorescence     

Harjeevan Kaur  Shilpa Gupta  Nitin Kumar  Javed Akhatar  S. S. Banga 《Euphytica》2014,199(3):325-338

Indian mustard (Brassica juncea (L) Czern & Coss) is naturally indeterminate. Plants with determinate inflorescence were first discovered in the self progenies of B. juncea (AABB; 2n = 36), resynthesized by combining A-genome from B. napus (AACC; 2n = 38) and B-genome from B. carinata (BBCC; 2n = 34). In the determinate plants, apical meristems were transformed into pods. In contrast, the inflorescence in the indeterminate plants continues to grow indefinitely while producing peripheral flowers. Genotyping and morphological characterization of newly developed determinate gene pool (A₈) showed a rapid emergence and progression of genetic and phenotypic alterations which continued even after seven generations of selfing. A large number of determinate genotypes (125) were evaluated to establish agronomic potential of determinate B. juncea. A high proportion of determinate genotypes outperformed the best indeterminate checks, suggesting that critical productivity related traits like pod number, seed size and oil content were not a function of indeterminacy. As the gene for determinacy has also been introgressed in B. napus and B. carinata, the stage is now set for future breeding to aim at crop architectural modifications through determinacy in all three types of oilseed Brassicas grown in the world. Our studies emphasized the role of polyploidy as a major force of differentiation at both genotypic and phenotypic level. Although, there was no direct correlation between evolution of genetic and phenotypic diversities following polyploidization. We suggest the use of polyploidy as a plant breeding tool to benefit from de novo variation rather than restricting its use as a method to overcome sterility following wide hybridization alone.  相似文献   

Sorption and desorption behaviors of diuron in soils amended with charcoal   总被引：1，自引：0，他引：1  

Yu XY  Ying GG  Kookana RS 《Journal of agricultural and food chemistry》2006,54(22):8545-8550

Charcoal derived from the partial combustion of vegetation is ubiquitous in soils and sediments and can potentially sequester organic contaminants. To examine the role of charcoal in the sorption and desorption behaviors of diuron pesticide in soil, synthetic charcoals were produced through carbonization of red gum (Eucalyptus spp.) wood chips at 450 and 850 degrees C (referred to as charcoals BC450 and BC850, respectively, in this paper). Pore size distribution analyses revealed that BC850 contained mainly micropores (pores approximately 0.49 nm mean width), whereas BC450 was essentially not a microporous material. Short-term equilibration (< 24 h) tests were conducted to measure sorption and desorption of diuron in a soil amended with various amounts of charcoals of both types. The sorption coefficients, isotherm nonlinearity, and apparent sorption-desorption hysteresis markedly increased with increasing content of charcoal in the soil, more prominently in the case of BC850, presumably due to the presence of micropores and its relatively higher specific surface area. The degree of apparent sorption-desorption hystersis (hysteresis index) showed a good correlation with the micropore volume of the charcoal-amended soils. This study indicates that the presence of small amounts of charcoal produced at high temperatures (e.g., interior of wood logs during a fire) in soil can have a marked effect on the release behavior of organic compounds. Mechanisms of this apparent hysteretic behavior need to be further investigated.  相似文献

Regeneration of mixed conifer forests under group tree selection harvest management in western Bhutan Himalayas     

Mani Ram Moktan  Georg Gratzer  William H. Richards  Tek Bahadur Rai  Dawa Dukpa  Kinley Tenzin 《Forest Ecology and Management》2009

Group selection tree harvest has been proposed as an ecologically sustainable silvicultural technique in mixed conifer forests of the western Bhutan Himalayas. To evaluate this silvicultural technique, we studied the ecological consequences of a group selection tree harvest in mixed conifer forests by assessing 127 circular plots (71 in logged and 56 in unlogged stands) in two forest management units (FMUs). Tree species composition and diversity were similar between logged and unlogged stands. Seedling density and height growth vary by species and were influenced by logging and microsites, with generally taller seedlings found in the logged versus unlogged stands. Early successional shade-intolerant species colonized logged stands. Seedlings growing on bare soil scarified by harvesting had medium vigour while seedlings growing on bryophyte mats showed good vigour in both logged and unlogged stands. Moist sites with a northerly aspect supported profuse conifer seedling regeneration, compared to sites with a dry southerly aspect. Damage to conifer seedlings from herbivore browsing was minimal. Conifer seedling density and height growth was negatively affected by competition from herbaceous vegetation, most notably Salvia officinalis. Group selection tree harvest in southern dry exposures in spruce-dominated stands is silviculturally unsuitable because it alters tree succession.  相似文献   

Assessment of feeding varying levels of Metabolizable energy and protein on performance of transition Murrah buffaloes     

Abdelfatah Abdelsalam Mustafa  Nitin Tyagi  Mayank Gautam  Alkesh Chaudhari  Jawid Sediqi 《Tropical animal health and production》2017,49(8):1637-1644

Fifteen close up pregnant Murrah buffaloes of mean body weight (668.3 ± 24.03) kg, lactation number (2.8 ± 0.17) and expected producing ability (EPA) (2125.7 ± 46.34) were randomly distributed into three groups each of five animals to investigate the performance at different levels of metabolizable energy and protein. Control group was fed as per ICAR Nutrient requirements of animals (2013) recommendation whereas treatment group (1) high metabolizable energy and high metabolizable protein (HMEMP) and group (2) low metabolizable energy and low metabolizable protein (LMEMP) were offered with ration containing 15% more and 15% less ME and MP, respectively. The feeding trial was carried out for the period of 40 days before parturition and continued for 120 days after parturition. Intake of dry matter (DM) (%BW) was similar among experimental groups. Metabolizable energy (ME) (MJ/100 kg BW) and metabolizable protein (MP) (g/100 kg BW) intake was highest in HMEMP followed by control and LMEMP group, respectively. Digestibility trial of 7 days was conducted at 60 days post-partum and it was observed that apparent digestibility coefficients (%) of DM, organic matter (OM), crude protein (CP), ether extracts (EE), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were similar among the experimental groups. Milk yield (kg/kg DMI) was similar among treatment groups whereas 6% fat corrected milk (FCM) was lower in LMEMP group as compared to HMEMP and control. No significant effect of dietary MP and ME levels on milk composition was observed among experimental groups. There were no significant difference in non esterified fatty acid (NEFA), blood urea nitrogen(BUN), growth hormone (GH) and insulin like growth factor-1(IGF-1) concentration among different experimental groups whereas concentration of immunoglobulin G (IgG) (μg/ml) was found to be lower in LMEMP. The study results indicate that nutrient digestibility and lactation performance was not affected with 15% variation in intakes of ME and MP in lactating Murrah buffaloes.  相似文献

Detection of intercellular adhesion genes and biofilm production in <Emphasis Type="Italic">Staphylococcus aureus</Emphasis> isolated from bovine subclinical mastitis     

Nirmala B. Dhanawade  Dewanand R. Kalorey  R. Srinivasan  Sukhadeo B. Barbuddhe  Nitin V. Kurkure 《Veterinary research communications》2010,34(1):81-89

Biofilm production by Staphylococcus aureus, an important virulence factor was investigated employing phenotypic and genotypic methods. A total of 102 S. aureus isolates from bovine subclinical mastitis cases were included in the study. Maximum number of biofilm producing strains were detected by Congo red agar (CRA) method (48.03%) followed by tube method (36.27%). Tissue culture plate method (TCP) without and with destaining identified 19.60 and 29.41% of S. aureus as biofilm producers, respectively. A polymerase chain reaction for detection of intercellular adhesion genes, icaA and icaD, responsible for biofilm formation was standardized. Of the 102 S. aureus isolates investigated, 36 (35.29%) strains revealed presence of both the genes. Considering polymerase chain reaction as a standard test, CRA and TCP without destaining were the most sensitive and specific, respectively. PCR technique standardized for detection of the icaA and icaD genes is reliable for identifying biofilm producing potential of S. aureus which may help in rapid detection of biofilm-producer Staphylococci. This would allow the early application of control measures.  相似文献   

Pyramiding Ty‐2 and Ty‐3 genes for resistance to monopartite and bipartite tomato leaf curl viruses of India          下载免费PDF全文

H. C. Prasanna  D. P. Sinha  G. K. Rai  R. Krishna  S. P. Kashyap  N. K. Singh  M. Singh  V. G. Malathi 《Plant pathology》2015,64(2):256-264

Breeding resistance to whitefly‐transmitted begomoviruses is an important goal of tomato breeding programmes worldwide. So far, resistance to begomoviruses in tomato has been achieved using wild species, and at least five resistance genes (Ty genes) have been studied. The present study was undertaken to combine Ty‐2 and Ty‐3 and to determine the effect of pyramiding on infection of tomato by three diverse begomovirus species. The diagnostic ability of the markers linked to Ty genes was assessed and marker‐assisted selection was used to develop pyramided tomato lines from the crosses between Ty stocks. Five stable pyramided tomato lines that differ in fruit morphology and yield potential were developed. The horticultural performance of pyramided lines in field trials showed that the yield and horticultural traits are well maintained in the plants. The response of these lines was assessed using agroinoculation and field tests in a disease hotspot. The pyramided lines and Ty‐3‐carrying lines exhibited a high level of resistance to the monopartite and two bipartite begomoviruses tested. The pyramided tomato lines developed in this study could be important genetic resources for sustainable tomato production in areas affected by tomato leaf curl virus disease. The combined results of disease resistance tests also showed that Ty‐3 is critical for achieving broad‐spectrum resistance. The limitations of relying on a single gene and the importance of pyramiding are discussed in the light of available evidence on frequent recombination in begomoviruses.  相似文献
