Different Sources and Levels of Copper Supplementation on Performance and Nutrient Utilization of Castrated Black Bengal (Capra hircus) Kids Diet

Mondal, M.K.,Biswas, P. Asian Australasian Association of Animal Productio 2007 Animal Bioscience Vol.20 No.7

Twenty eight 3-4 month old castrated Black Bengal kids (Capra hircus) were used to determine the effects of source and level of dietary copper (Cu) concentration on their performance and nutrient utilization. Cu was supplemented (0, 10, 20 and 30 mg/kg diet DM) as copper sulfate ($CuSO_4$, $5H_2O$) or copper proteinate (Cu-P). Kids were fed a basal diet containing maize (19.5%), soybean (17.0%), deoiled rice bran (56.5%), molasses (4.0%), di-calcium phosphate and salt (1.0% each) and mineral and vitamin mixture (0.5% each) supplements at 3.5% of body weight to meet NRC (1981) requirements for protein, energy, macro minerals and micro minerals, excluding Cu. The basal diet contained 5.7 mg Cu/kg, 122.5 mg Fe/kg, 110 mg Zn/kg, 0.26 mg Mo/kg and 0.32% S. $CuSO_4$ or Cu-P was added to the basal diet at the rate of 10, 20 and 30 mg/kg. Kids were housed in a well ventilated shed with facilities for individual feeding in aluminum plated metabolic cages. Blood samples were collected from the jugular vein on d 0, 30, 60 and 90 to determine hemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC), total leukocyte count (TLC) and serum enzymes (alkaline phosphatase, alanine transferase and aspertate transferase). A metabolism trial of 6 days duration was conducted after 90 days of experimental feeding. Statistical analysis revealed that source and level of Cu supplementation improved live weight gain (p<0.04) and average daily gain (p<0.01). No significant contribution of source and level of Cu to alter serum serum enzymes was evident. Goats fed Cu-P tended to have higher Hb, PCV and TEC than with $CuSO_4$ supplementation. Cu-P increased digestibility of ether extract (EE, p<0.02) and crude fiber (p<0.05) and showed an increasing trend (p<0.09) for digested crude protein (CP) and crude fiber (CF). Supplemental dose of Cu linearly improved (p<0.02) digestibilities of dry matter (DM), organic matter (OM), EE and nitrogen free extract (NFE). Though the absorption of nitrogen (N) was not affected (p>0.10) by both source and dose of Cu, N retention was affected (p<0.04) and there was a significant $Source{\times}Dose$ interaction (p<0.05). Final body weight (BW) was not influenced (p>0.10) by the source of Cu but increasing dose of Cu increased (p<0.04) the BW of kids. TDN intake (g/kg $W^{0.75}$) was higher (p<0.05) with the increased dose of Cu and there was a significant $Source{\times}Dose$ interaction. It was concluded that supplementation of Cu from different sources and varying dose level in a concentrate based diet may improve performance, nutrient utilization and plane of nutrition in castrated Black Bengal kids. The effects on performance and nutrient utilization are more pronounced with Cu-P than $CuSO_4$ supplementation. Higher dose of Cu showed better result than lower dose.

Mondal, S.,Lin, C. C.,Chen, W. P.,Zhang, Z.-W.,Alcock, C.,Axelrod, T.,Bianco, F. B.,Byun, Y.-I.,Coehlo, N. K.,Cook, K. H.,Dave, R.,Kim, D.-W.,King, S.-K.,Lee, T.,Lehner, M. J.,Lin, H.-C.,Marshall, S. American Institute of Physics 2010 The Astronomical journal Vol.139 No.5

<P>The Taiwanese-American Occultation Survey (TAOS) project has collected more than a billion photometric measurements since 2005 January. These sky survey data—covering timescales from a fraction of a second to a few hundred days—are a useful source to study stellar variability. A total of 167 star fields, mostly along the ecliptic plane, have been selected for photometric monitoring with the TAOS telescopes. This paper presents our initial analysis of a search for periodic variable stars from the time-series TAOS data on one particular TAOS field, No. 151 (R.A. = 17<SUP>h</SUP>30<SUP>m</SUP>6<img entity='fs' SRC='http://ej.iop.org/icons/Entities/fs.gif' ALT='fs' ALIGN='BASELINE' />7, decl. = 27°17'30'', J2000), which had been observed over 47 epochs in 2005. A total of 81 candidate variables are identified in the 3 deg<SUP>2</SUP> field, with magnitudes in the range 8 < R < 16. On the basis of the periodicity and shape of the light curves, 29 variables, 15 of which were previously unknown, are classified as RR Lyrae, Cepheid, δ Scuti, SX Phonencis, semi-regular, and eclipsing binaries.</P>

Mondal, Nandan K.,Siddique, Shabana,Banerjee, Madhuchanda,Roychoudhury, Sanghita,Mukherjee, Sayali,Slaughter, Mark S.,Lahiri, Twisha,Ray, Manas R. Occupational Safety and Health Research Institute 2017 Safety and health at work Vol.8 No.2

Background: There are a million ragpickers in India who gather and trade recyclable municipal solid wastes materials for a living. The objective of this study was to examine whether their occupation adversely affects their immunity. Methods: Seventy-four women ragpickers (median age, 30 years) and 65 age-matched control housemaids were enrolled. Flow cytometry was used to measure leukocyte subsets, and leukocyte expressions of $Fc{\gamma}$ receptor I (CD64), $Fc{\gamma}RIII$ (CD16), complement receptor 1 (CD35) and CR3 (CD11b/CD18), and CD14. Serum total immunoglobulin-E was estimated with enzyme-linked immunosorbent assay. Results: Compared with the controls, ragpickers had significantly (p < 0.0001) higher levels of CD8-T-cytotoxic, CD16+CD56+natural killer, and CD4+CD45RO+memory T-cells, but depleted levels of CD19+B-cells. The percentage of CD4+T-helper-cells was lower than the control group (p < 0.0001), but their absolute number was relatively unchanged (p = 0.42) due to 11% higher lymphocyte counts in ragpickers. In ragpickers, the percentages of CD14+CD16+intermediate and CD14dim CD16+nonclassical monocyte subsets were elevated with a decline in CD14+CD16-classical monocytes. The expressions of CD64, CD16, CD35, and CD11b/CD18 on both monocytes and neutrophils, and CD14 on monocytes were significantly higher in ragpickers. In addition, ragpickers had 2.7-times more serum immunoglobulin-E than the controls (p < 0.0001). After controlling potential confounders, the profession of ragpicking was positively associated with the changes. Conclusion: Ragpicking is associated with alterations in both innate (neutrophils, monocytes, and natural killer cell numbers and expression of complement and $Fc{\gamma}$ receptors) and adaptive immunity (numbers of circulating B cells, helper, cytotoxic, and memory T cells).

Borun K. Mondal,Sukumar Devnath,Dinesh C. Shaha,Mohammed N.A.khan,최재석 한국수산과학회 2008 Fisheries and Aquatic Sciences Vol.11 No.2

Relationships between total length (TL) and fecundity, body weight and fecundity, ovary length and fecundity, and ovary weight and fecundity of hilsa shad, Tenualosa ilisha Hamilton, collected from Kuakata, Patuakhali, Bangladesh, were studied. During the sampling period, the fecundity of hilsa was found to range from 169,000 (fish TL=28.0 cm, weight=250 g) to 1,088,000 (fish TL=40.5 cm, weight=955 g) with a mean of 520±53×1,000. The number of eggs per gram of ovary for samples collected from the anterior, middle, and posterior regions of the ovary were also recorded, but no significant variation was found among ovary regions at the 5% level of significance. Fecundity increased with fish TL and weight. The regression equations obtained in arithmetic forms of relationships between TL and fecundity (F), body weight (BW) and fecundity, ovary length (OL) and fecundity, and ovary weight (OW) and fecundity were F=-887,896+ 40,511×TL (r=0.85), F=67,577+755.44×BW (r=0.85), F=-562,070+87,668×OL (r=0.75) and F=124,815+6,596.7×OW (r=0.84), respectively. The relationships between fecundity and TL, body weight, ovary length, and ovary weight were linear, and the ‘r’ values were highly significant (p<0.01). These results provide valuable data for the restoration of hilsa resources, which are economically important but have shown reduced productivity in nations adjacent to the Bay of Bengal.

Application of biotechnology for genetic improvement of tea(Camellia sinensis L.)

Tapan K. Mondal 한국차학회 2003 한국차학회지 Vol.9 No.3

Tea is one of the most important non-alcoholic beverage drinks worldwide. Although conventional breeding and propagation contributed significantly for last several decades to improve this crop. Moreover, tea is a unique horticultural crop which not only grow as monoculture but also the tender shoots and foliage harvested at periodic intervals from the very second year after planting to 100 or more years. Thus tea plant experiences several biotic and abiotic stresses through out the life. Therefore application of biotechnology become attractive to overcome the limitations of conventional breeding coupled with the demand for increasing productivity with lower cost of production. The various approaches such as microproopagation, genetic transformation and molecular biology which are applied to the Indian tea cultivar are discussed here.

Inverstigations of Different Modes in a Magnetized Plasma Having Positive Ions and Electrons with a Density Gradient

Hitendra K. Malik,Ravinder Kumar,Sushanta K. Mondal 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.54 No.4

Considering a more realistic situation of an inhomogeneous plasma, we attempted to investigate various types of possible modes under the effect of an external magnetic field by using a normal mode analysis (NMA) of the basic fluid equations. These modes are confirmed with the help of a reductive perturbation technique (RPT) that employs a nondimensional form of the basic fluid equations and a transformation of the space and time coordinates to the wave frame of reference via the stretched coordinates appropriate for the case of an obliquely applied magnetic field. The propagation characteristics of four possible types of modes are studied through their phase velocities under the effects of the magnetic field, the density inhomogeneity, the ion temperature and the wave propagation angle.
