Quality poultry meat depends upon the feed and as such there are many commercially available feeds. However, their composition and standard by and large throughout the year may not remain same due to obvious reasons. Moreover, there is no mention of locally produced feed particularly in the north eastern part of India. The major objective of this study was to prepare mesh feed E1 with the available ingredients as well as their effect were compared with that of the two commercially available feed Amrit and Godrej (E2 and E3) in terms of Crude protein, fats and element composition. The findings showed that the protein content (240 g/kg) and fats (105 g/kg) in the breast muscle of female was higher in the E3 received against the broiler chicken received local feed. Element analysis of the E1, E2 and E3 depicted significantly higher value of Ca, K, Cu Zn and Se against the commercial feed. Other elements like Mg, Na, Fe, P, and Mn showed no variation while compared E1, E2 and E3 together. Thus the present findings suggest that the local feed E1 could be accepted at per with that of the commercial feed for poultry.

Objective： To test the antioxidant, antidiabetic, anticancer and antibacterial activities along with phytochemicals of Sonneratia apetala Buch.-Ham. Methods： The antibacterial activity was determined by agar well diffusion method. The antioxidant activity was determined by standard assay. The antidiabetic activity was evaluated by α-glucosidase inhibition assay and in vivo anticancer property was determined against Ehrlich ascites carcinoma （EAC） cells in Swiss Albino mice. Further partial characterization of the methanol extracts was carried out by thin layer chromatography, high performance liquid chromatography, 1H nuclear magnetic resonance spectroscopy and Fourier transform-infra red spectrum spectral analysis. Results： Four solvent extracts （acetone, ethanol, methanol and aqueous） of leaf and bark possess strong antioxidant properties. In vivo anticancer activity of methanol extract leaf indicated positive activity showing 34% inhibition against EAC cells in Swiss Albino mice. All extracts exhibited a-glucosidase inhibitory activity in a dose-dependent manner indicating presence of promising antidiabetic properties. The extracts possess strong antibacterial activity against the selected pathogenic bacteria （minimal inhibitory concentration ranging from 1.25-5.00 mg/mL）. The partial characterization of the methanol extracts of leaf and bark revealed the presence of phenolics as the lead compound responsible for studied bioactivities of the plant extracts. Conclusion： Sonneratia apetala extracts have potent antibacterial, antioxidant, antidiabetic and anticancer properties which can be further exploited for its pharmaceutical applications.

Mangroves are salt-tolerant forest ecosystem that extends between tropical and subtropicalintertidal regions of the world. Mangroves are biochemically unique vegetation that produce wide array of naturalproducts with immense medicinal potential. These plants are the most valuable resources and provide economicand ecological benefits to the coastal people. Natural products from these plants are of great interest as theyprovide innumerable direct and indirect benefits to human beings for the discovery of novel antimicrobial andother bioactive compounds. They possess active metabolites with some novel chemical structures that belong todiverse chemical classes such as alkaloids, phenol, steroids, terpenoids and tannins. Several mangrove specieshave been used in traditional medicine or have few applications as insecticide and pesticide. To date, severalmangroves, and their associated species and solvent extracts are screened for antimicrobial activity along withthe presence of potent bioactive compounds. The present article emphasizes and creates awareness aboutthe potential mangrove plants and their associates as a source of biologically active compounds with potentantimicrobial properties. This paper also elaborates the mechanisms of action and various methods for screeningof antimicrobial compounds.

This study investigated an economic order quantity (EOQ) model with completebackorder for fixed lifetime perishable items under multiple advance and delayedpayments policies. Here, a new type of business policy is consideredwhere supplieroffers the retailer to pay a fraction of the purchasing cost before the order deliverybymultiple equal installments starting from the ordering time and the rest amountafter the delivery by multiple equal installments. Here, some theoretical results areillustrated to determine the conditions of existence and uniqueness of the optimalsolutions. A closed form solution is determined to solve the proposed model underapproximation. Some numerical examples are provided to examine the validity ofthe proposed model. Finally, sensitivity analyses are presented to obtain the effectof optimal policy and provide some managerial insights of the model.
