Effect of Withania somnifera (L. Dunal) root as a feed additive on immunological parameters and disease resistance to Aeromonas hydrophila in Labeo rohita (Hamilton) fingerlings
“…Previously, enhancement of phagocytic and NBT activities following administration of herbal products in fish species have been reported in a number of studies (Rao et al 2006;Sahu et al 2007;Punitha et al 2008;Pratheepa et al 2010;Sharma et al 2010;Behera et al 2011;Uthayakumar et al 2014b;Anusha et al 2014).…”
In this study, the immunomodulatory properties of Lawsonia inermis (henna) in common carp, Cyprinus carpio was investigated. Fish were intraperitoneally (i.p.) injected with 6, 60 or 600 mg kg -1 body weight (BW), of the methanolic soluble fractions of L. inermis. The extract at 60 and 600 mg kg -1 BW, significantly (p \ 0.05) enhanced some non-specific immune parameters such as serum lysozyme and bactericidal activity, phagocytic and respiratory burst activity, total leucocyte count (TLC), lymphocyte, monocyte and neutrophil number. Disease resistance against Aeromonas hydrophila has also been improved following herbal treatment. This preliminary study indicates the beneficial effect of L. inermis in improving immune status and controlling infectious diseases in aquaculture.

“…Feed containing W. somnifera extract at the rate of 200 mg kg À1 significantly reduced the mortalities of juvenile greasy grouper, Epinephelus tauvina against Vibrio harveyi infection [32] and in Labeo rohita against A. hydrophila [33]. In this study, we attempted the effect of W. somnifera supplementation diet on innate immune parameters including total hemocyte count (THC), phenoloxidase (PO), nitric oxide (NO), superoxide anion (O 2 À ), and superoxide dismutase (SOD) production in M. rosenbergii against A. hydrophila infection.…”
“…Total immunoglobulin in serum was estimated according to the method described by Anderson and Siwicki (1995) and modified by Sharma et al (2010). Serum (0.1 ml) was placed into a plastic serum vial and mixed with 0.1 ml of 12 % polyethylene glycol in DI water.…”

The effects of inulin and mannanoligosaccharide (MOS) on the growth performance and non-specific immunity of grass carp were studied. Two doses of prebiotic fiber with 0.2 or 2% of the fibers are being mixed into fish feed pellets. Fish growth as well as selected non-specific immune parameters of grass carp were tested in a feeding trial, which lasted for 8 weeks. Fish was fed at 2.5% body mass per day. INU02, INU2, and MOS2 significantly improved relative weight gain, specific growth rate, protein efficiency ratio, and food conversion ratio of grass carp fed with food waste-based diet. In terms of non-specific immune response, grass carp showed significant improvement in all three tested parameters (total serum immunoglobin, bactericidal activity, and anti-protease activity). Adding 2% of inulin (INU2) into food waste diets seemed to be more preferable than other supplemented experimental diets (INU02, MOS02, MOS2), as it could promote growth of grass carp as well as improving the non-specific immune systems of grass carp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
