| Abstract | This study was conducted to evaluate the effects of zinc-bearing clinoptilolite (ZnCP) on broilers challenged with Salmonella pullorum for a 21-d feeding trial. A total of 240 one-day-old chickens was allocated into 4 treatment groups: 1) nonchallenged control (CON) fed basal diet; 2) S. pullorum-challenged control (SCC) fed basal diet; 3) Salmonella challenge fed basal diet plus antibiotic (ANT); 4) Salmonella challenge fed basal diet plus 0.2% ZnCP (ZnCP). Compared with CON, Salmonella challenge caused adverse effects on ADG (P<0.05), ADFI, feed/gain ratio in broilers, Salmonella and Lactobacillus colonies at 7 d (P<0.05) and 21 d, and serum diamine oxidase (DAO) activity. Moreover, the relative weight of spleen of 21-d birds, malondialdehyde (MDA) content of jejunual and ileal mucosa at 21 d, and the superoxide dismutase (SOD) activity of ileal mucosa were also significantly negatively affected by SCC treatment (P<0.05). Supplementation of ZnCP in basal diet significantly improved ADG and reduced Salmonella colonies in cecal contents and serum DAO activity both at 7 and 21 d (P<0.05), compared with SCC. Furthermore, supplementation with ZnCP as well as ANT signiï¬cantly decreased the relative weight of spleen at 21 d, reduced MDA contents of jejunual and ileal mucosa at 21 d (P<0.05), and improved the SOD activity of ileal mucosa at 7 d as compared with SCC (P<0.05). The results suggested that ZnCP addition in feed exerted protective effects on performance and gut health of broilers against S. pullorum infection. |

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.
