| Abstract | The objective of this study was to determine the effect of dietary lycopene supplementation on the growth performance, antioxidant enzyme activity of serum and liver, and gene expressions associated with Kelch-like ech-associated protein-1 (Keap1) / Nuclear Factor E2-related factor 2 (Nrf2) pathway in liver of Arbor Acres broilers. 288 1-day-old male broilers were randomly divided into 4 treatments with 6 replicates and 12 for each replicate. The control group was fed with the basal diet, while the treated groups were fed with the basal diet with 10, 20, 30 mg/kg lycopene in powder. Feed and water were provided ad libitum for 42 days. Compared with the control group, a) the average daily gain increased (P = 0.002 vs. P = 0.001) and the feed conversion ratio decreased (P = 0.017 vs. P = 0.023) in groups treated with lycopene in the grower and whole phases, and the average daily feed intake was quadratically affected (P = 0.043) by lycopene in the grower phase; b) the serum superoxide dismutase content was linearly affected (P = 0.035) by lycopene at 21d; c) the serum glutathione peroxidase content, superoxide dismutase content and total antioxidant capability were higher (P = 0.014, P = 0.003, P = 0.016, respectively) in 30 mg/kg lycopene group at 42 d; d) the liver glutathione peroxidase and superoxide dismutase contents in groups treated with lycopene were higher (P = <0.001 vs. P = <0.001) at 21 d; e) the liver glutathione peroxidase content was higher (P = <0.001) in 20 and 30 mg/kg lycopene groups, at 42 d; f) the mRNA expression levels of Nrf2, superoxide dismutase 2, NAD(P)H quinone dehydrogenase 1 and heme oxygenase 1genes were higher (21 d: P = 0.042, P = 0.021, P = 0.035, P = 0.043, respectively; 42 d: P = 0.038, P = 0.025, P = 0.034, P = 0.043, respectively) in 20 and 30 mg/kg lycopene groups at 21 and 42 d. The 30 mg/kg lycopene concentration improved the growth performance, antioxidant enzyme activity in serum and liver, and gene expression in Keap1-Nrf2 signalling pathway of Arbor Acres broilers. |

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.
