| Abstract | A 50-day feeding trial was conducted to evaluate the effects of five different levels of low molecular weight chitooligosaccharides (LMW-COS) (0, 0.1, 0.2, 0.4, and 0.8 g kg−1) on growth performance, serum parameters, body composition, and non-specific immunity in Nile tilapia (Oreochromis niloticus). A total of 600 fish were divided into 5 treatments with 4 replicates of 30 fish per tank. The results showed that dietary supplementation with 0.4 or 0.8 g kg−1 COS significantly improved the final body weight, specific growth rate, feed efficiency rate, and protein efficiency ratio of fish (P < 0.05). The supplementation of COS did not significantly affect the content of blood albumin, globin, and glucose, but the trend of enhancing blood total protein and lowering cholesterol and triglyceride was observed with the gradient levels of COS. Immune responses assay showed that dietary supplementation with 0.4 or 0.8 g kg−1 COS significantly improved the phagocytic activity, serum bactericidal activity, and lysozyme activity in tilapia (P < 0.05); there were no significant differences between 0.4 and 0.8 g kg−1 of COS (P > 0.05). In one word, the supplementation of 0.4 and 0.8 g kg−1 COS significantly increased the growth performance and non-specific immunity of Nile tilapia; the recommended COS supplementation in diet is 0.4 g kg−1 diet. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
