| Abstract | This study was carried out to validate the efficacy ofSpondias mombin, used locally as an anthelmintic, and to standardize the effective dose of the plant extract required for worm control in livestock. In vitro andin vivo studies were conducted to determine the direct anthelmintic effect of ethanolic and aqueous extracts ofS. mombin towards different ovine gastrointestinal nematodes. A larval development assay (LDA) was used to investigate thein vitro effect of extracts on strongyle larvae. Another study was conductedin vivo to evaluate the therapeutic efficacy of the extracts administered orally at dose rates of 125, 250, 500 mg/kg to sheep naturally infected with gastrointestinal nematodes. Twenty sheep were selected on the basis of positive faecal egg counts (750 epg). The sheep were allocated randomly to a non-medicated control group (A) or to groups given 125 mg/kg (B), 250 mg/kg (C) or 500 mg/kg (D) of extract, respectively. Sheep in groups B–D were given extracts orally on two days. Individual faecal egg counts were performed on days 0, 3, 6, 9 and 12. The presence ofS. mombin extracts in in vitro cultures of larvae decreased the survival of L$_{3}$ larvae. The LC$_{50}$ of the aqueous extract ofS. mombin was 0.907 mg/ml, while the LC$_{50}$ of the ethanolic extract was 0.456 mg/ml. This difference in LC$_{50}$ was statistically significant (p>0.05). The mean percentage faecal egg reduction of sheep drenched with 500 mg/kgS. mombin extracts was 15.0%, 27.5%, 65.0%, 65.0%, 100.0% againstHaemonchus spp., Trichostrongylus spp., Oesophagostomum spp., Strongyloides spp. and Trichuris spp. respectively, on day 12. Extracts ofS. mombin could find application in the control of helminths in livestock. |

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.
