| Abstract | To assess the growth-promoting potential of three medicinal herbs, Alteranthera sessilis, Eclipta alba and Cissus quadrangularis, a 90-day feeding trial was conducted on Macrobrachium rosenbergii post-larvae (PL) fed with these herb-incorporated feeds. The growth parameters (survival rate, weight gain, specific growth rate and protein efficiency ratio) were significantly (P < 0.05) higher in experimental-diets-fed PL when compared with control. These herbs have acted as appetizer and significantly enhanced the activities of digestive enzymes (protease, amylase and lipase). This in turn significantly (P < 0.05) influenced the parameters of energy utilization (feeding rate, absorption rate, conversion rate, metabolic rate and NH3 excretion rate), which ultimately reflected on significant (P < 0.05) increases in concentrations of biochemical constituents (total protein, amino acid, carbohydrate and lipid, and essential amino acids and unsaturated fatty acids). Therefore, it was believed that synthesis of protein was activated due to the active principles of these herbs and resulted in growth promotion. In this study, the higher (P < 0.05) minerals (Na+ and K+) recorded indicate the fact that their balance was maintained. Similarly, the non-enzymatic antioxidants (vitamin-C and -E) status were also improved significantly (P < 0.05) due to herbal incorporation, which provide additional protection. Further, the haemocytes count and population was also found to be higher (P < 0.05), which ensures prevalence of good host-defence mechanisms in herb-incorporated-feeds-fed PL. Among three herbs tested, C. quadrangularis-incorporated-feed-fed PL showed the best survival, growth and protection as well as production followed by E. alba and A. sessilis. Therefore, these herbs can be incorporated in artificial feed formulations for sustainable development of Macrobrachium culture. |

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.
