The present study evaluates the effect of dietary zinc supplementation on reproductive and productive performance of Teressa goat, an indigenous species ofAndaman and Nicobar Islands.

A batch of zinc borotellurite glasses doped with Li2O, W2O3 and rare earth ions were synthesized with varied composition and investigated for dielectric properties in the frequency range from 50Hz to 15MHz and temperature from 300K to 620K. Electric moduli and impedance were estimated. Dielectric relaxation time from both impedance and moduli data were determined. Activation energy for relaxation time has been determined. Nature of the phase of the glasses has been understood in terms of cole-cole plots. Normalized moduli plots were made to learn temperature dependance of relaxation processes. For the first time, glasses of the present composition have been exposed for detailed dielectric relaxation studies.

KEYWORDS Morinda citrifolia Livestock Poultry Growth Production Immunomodulatory Properties ABSTRACTMorinda citrifolia L. is commonly known as Noni and has been found to have wide range of medicinal properties. It is usually found in the coastal region in many countries including Andaman and Nicobar Islands and belongs to the family Rubiaceae. This small evergreen tree is widely grown and well adapted to the tropics and can grow in fertile, acidic, alkaline and saline affected soils. It tolerates high soil salinity and brackish water stagnation. All the components of this plant have high demand in case of alternative medicines and herbal medicines. Due to its high demand and as a source of revenue generation the detail study on its nutritional benefits and therapeutic values are essential for its commercial exploitation. More than 200 nutraceutical compounds have been identified from the plant. Morinda citrifolia is reported to have broad spectrum biological activities such as antimicrobial, immunomodualtory, antioxidant wound healing etc. Apart from the in-vitro scientific validation of the activities and in-vivo trial in some lab animal model, the plant has been used for livestock and poultry health and production. A lot of reviews have been written on the different uses of Noni, however, scientific review on the use of this plant on the growth, production, immunomodulator and other pharmacological activities of M. citrifolia in livestock and poultry has not been compiled. Therefore this review discusses the compilation of the work done on the use of M. citrifolia in livestock and poultry.
