Biochemical and hemato-immunological parameters in juvenile beluga (Huso huso) following the diet supplemented with nettle (Urtica dioica)

Effects of dietary onion (Allium cepa) powder on growth, innate immune response and hemato–biochemical parameters of beluga (Huso huso Linnaeus, 1754) juvenile

“…Similar to the present study, the increase of growth performance and feed efficiency were recorded in juvenile beluga after feeding ginger (Zingiber officinale) [28] and nettle (Urtica dioica) [35]. Additionally, a previous study revealed that onion extract was one of the most effective dietary additives that improve weight gain of juvenile olive flounder (P. olivaceus) [36].…”

“…Many data were published to show that the herbal plant could be act as immunostimulants and increase the total WBC [37]. The increase in WBC counts, and other blood cells, following feeding of onion diet, demonstrates the immunostimulatory effects and anti-infection properties of onion which is in line with the previous work of Gholipour kanani et al [28] and Binaii et al [35] who obtained increased WBC after feeding juvenile beluga with ginger and nettle diet respectively. It could be explained that the bioactive compounds polyphenols, flavonoids and quercetin found in onion prevented fish from infection by triggering immune system [38].…”

“…Elevated lysozyme level was measured in Crucian carp (Carassius auratus gibelio) (Chen, Wu, Yin, & Li, 2003) and Large yellow croaker (Pseudosciaena crocea) (Jian & Wu, 2003) after feeding the fish with various Chinese herbal. However, unlike this study, lysozyme activity was not influenced in juvenile Beluga (Huso huso) fed with ginger and garlic (Gholipour Kanani et al, 2014) and Nettle (Urticadioica) (Binaii et al, 2014). The increasing trend could be due to lysozyme, a humoral component of the non-specific defense mechanism, that has the ability to prevent the growth of infectious microorganism by splitting β-1, 4 glycosidic bonds between N-acetylmuramic acid and Nacetylglucosamine in the peptidoglycan of bacterial cell walls (Choi et al, 2008;Secombes, 1996).…”

Trial on using of some herbal extracts as promising immunoprophylaxis feed additives in cultured Oreochromis niloticus

“…They contain various active compounds like alkaloids, flavanoids, pigments, phenolics, terpenoids, steroids and essential oils with very potent growth promoting, immunostimulating and anti-microbial properties [5,6]. Among these plants, Onion (Allium cepa) and its flavonoid compounds have been used to accelerate the growth performance of fish beside their potential immunostimulants [7] antibacterial and antioxidant effects [8].The high soluble fiber content of onion could be used as prebiotic feed additive [9] Literature approved onion as one of the most effective immunostimulants that improvesthe innate immunity of juvenile Olive flounder (Paralichthysolivaceus) [10] Another plant is Barley (Hordeumvulgare), a member of the grass family, Poaceae, is one of the main M EDICINAL HERBS and some plant extracts are natural feed additives which have a great impact on fish health. The present study focused on three dietary plant extracts to determine which one could be used as immunostimulant in aqua-feed.…”
