In June 1999, Richard Smalley, Nobel laureate in chemistry, addressed the US House Committee on Science on the benefits of nanotechnology. "The impact of nanotechnology on the health, wealth, and lives of people," he said, "will be at least the equivalent of the combined influences of microelectronics, medical imaging, computer-aided engineering and man-made polymers developed in this century."
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. Nanoparticles that occur naturally such as volcanic ash, soot from forest fires or the incidental byproducts of combustion processes are physically and chemically heterogeneous and often termed as ultrafine particles.
Recent advances in the field of nanotechnology, particularly die ability to prepare highly ordered nanoparticulates of any size and shape, have led to the development of new biocidal agents. Nano-materials are called "a wonder of modern medicine". It is stated that antibiotics kill perhaps a half dozen different disease-causing organisms but nano-materials can kill plentiful.
Metal nanoparticles have various functions that are not observed in bulk phase and have been studied extensively because of their exclusive catalytic, optical, electronic, magnetic and antimicrobial wound healing and anti-inflammatory properties . Over the past few decades, inorganic nanoparticles, whose structures exhibit significantly novel and improved physical, chemical, and biological properties and functionality due to their nano-scale size, have elicited much interest.

Biosynthesis of nanoparticles is an approach of synthesizing nanoparticles using plants having biomedical applications. This approach is an environment-friendly, cost-effective, biocompatible, safe, green approach Green synthesis includes synthesis through plants, bacteria, fungi, algae etc. NPs synthesized from biomimetic approach show more catalytic activity and limit the use of expensive and toxic chemicals. These plant extract secrete some phytochemicals that act as both reducing agent and capping or stabilization agent.
The "green" synthetic strategy requires the capping materials to be environmentally benign, non-toxic and renewable. In this context, plant extract coating seems to be a promising route to accomplish this task, based on its reliability, high protecting performance, good stability, biocompatibility and ease of implementation.
Plants are most preferred source of NPs synthesis because they lead to large-scale production and production of stable, varied in shape and size NPs . Bio-reduction involves reducing metal ions or metal oxides to 0 valence metal NPs with the help of phytochemicals like polysaccharides, polyphenols compounds, vitamins, amino acids, alkaloids, terpenoids secreted from the plant.
BACKGROUND OF THE INVENTION
Calcium carbonate is a widely available natural inorganic compound, also known as limestone, chalk or marble. It is a white, caustic, alkaline, crystalline solid at room temperature.
Calcium Rich Food for Birds. All birds need plenty of calcium in their diets, as it facilitates bone formation and normal nerve, brain and muscle function. However, laying females need an especially high amount to form their eggs, the shells of which are almost pure calcium carbonate.

In relation to poultry production, lime is a generic term used to refer only to the manufactured forms of lime. These forms of lime are quicklime, which is calcium oxide (CaO), and hydrated lime, which is calcium hydroxide (Ca(0H)2), The terms whitewash and, less commonly, milk of lime are used to refer to a suspension of hydrated lime in water. (For the purposes of this article, the term lime does not include agricultural lime, which is crushed limestone. Agricultural lime should not be used in poultry houses.)

SUMMARY OF INVENTION
A nanoparticle is a piece of material that is so small it has to be measured in nanometers. One nanometer equals one-billionth of a meter. For comparison, 10,000 nanoparticles could fit in the diameter of a human hair .Nano particles refer to a particle size of roughly 1 to 100 nm .At this scale the physical, chemical and biological properties of material differ fundamentally and often unexpectedly. These nanomineral particles are having higher potential than their conventional sources and thus reduce the quantity required.Chickens need calcium. It's important for their egg production. Hens without enough of it in their diets can lay soft or no shell eggs. Fortunately. Nano calcium is having a great potential as performance enhancer in broiler chicken production even at very lower doses than the conventional organic and inorganic sources.
DRAWING:
Fig 1, Illustrating shows the flow chart of Nano Calcium in which Incubation period results in a change of color of the mixture to Light Brown which is a visual confirmation of the synthesized NPs . Further, synthesized nanoparticles are further characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM).
Fig 2, shows the SEM micrograph of Calcium oxide nanoparticles at 200 nm (nanometer) in which SEM technique was employed to visualize the size of calcium oxide nanoparticles. The formation of calcium oxide nanoparticles as well as their morphological dimensions in the SEM analysis demonstrated that the average size was from 78-1J 6 nm with inter-particle distance.

Fig 3, is Sample of Nano calcium oxide
Fig 4 , Shows the dual role of the plant extract as a reducing and capping agent and presence of some functional groups was confirmed by FTIR analysis . A broad band between 3441 cra-1 is due to the N-H stretching vibration of group NH2 and OH the overlapping of the stretching vibration of attributed for DMSO and plant extract molecules. The observed peaks at 1028 cm-1 denote -C-OC- linkages, or -C-O- bonds. The observed peaks are mainly attributed to flavanoids and terpenoids excessively present in plants extract. From FT-TR results, it can be concluded that some of the bioorganics compounds from plant extract formed a strong coating/capping on the nanoparticles.
DETAILED DESCRIPTION OF THE INVENTION
Preparation Of Plant Extract
The plant part is washed thoroughly in running tap water and sterilized using double distilled water Then, the plant part is kept for drying at room temperature followed by weighing and then crushing it using a mortar and pestle.
DMSO(Dimethyl Sulfoxide) is added to the plant part according to the desired concentration and continuous stirring using a magnetic stirrer. The solution is filtered using Whatman filter paper and the obtained clear solution was used as a plant extract.
Bio-availability of Ca
The major mineral, calcium is highly essential to maintain the skeletal structure. It is a divalent caption, which cannot be synthesized in the body and only way to get it is through food and supplementation. Thus it can be categorized as essential mineral like one of the essential amino acids. When the feed is deficient in calcium, the calcium will be drawn from the bones. Majority of the calcium in the animal and bird body is stored in bones .

Presently, added minerals are used as nanoparticles in order to increase absorption and subsequent decreased presence in poultry excreta. Chan et al.(2006) and Gross et al.(2014) have reported that calcium phosphate materials in nano-size have higher specific surface area and surface roughness compared to the conventional calcium phosphate. Weiss et al.(2006) reported that nanoparticle-sized ingredients might increase the functionality or bioavailability of ingredients and nutrients, thereby minimize the concentrations needed in the food product. Calcium phosphate materials in nano-size are expected to have better bioactivity compared to conventional materials because supplementation of minerals in nano form (Se, Cr and Zn) increases the bioavailability and efficiency of utilization by increasing the surface area. The usefulness of nano form in reducing the mineral quantify to half or more in the diet will reduce the cost of feeding when the actual production of calcium phosphate nano-particles is upsealed to an industrial level.
Advantages of NANO Ca
• Swain et o/.(2015) reported that nano minerals are having a great potential even at very lower doses than the conventional organic and inorganic sources.
• Nano calcium is having a great potential as performance enhancer in broiler chicken production even at very lower doses than the conventional organic and inorganic sources.

• When broiler birds are fed witfi nano form of calcium by replacing upto 50% requirement of dicalcium phosphate, they showed a best feed conversion ratio and differed significantly from the control groups.
• Calcium is responsible for construction, formation and maintenance of bone and
teeth.
t
• This function helps reduce the occurrence of osteoporosis. It is also a vital
component inblood clotting systems and wound healing.

THE DEFICIENCES / DRAWBACKS IN THE PRESENT INVENTION
Particle size is an important factor for good mineral absorption, because a fundamental physical law states that the smaller the particle, the greater the relative particle surface. It is this surface that the body uses to break down and absorb nutrients. The larger this surface, the better nutrients can be utilized.
