Effect of Ethanolic Extract of Pedalium murex on Growth and Haemato-Immunological Parameters of Labeo rohita

Dietary Aloe vera supplementation on growth performance, some haemato-biochemical parameters and disease resistance against Streptococcus iniae in tilapia (GIFT)

“…Similar findings were also reported in O. mykiss fed 1% A. vera supplemented diet [30]. In addition to A. vera, several medicinal herbs have been reported to significantly enhance serum total protein content in different fish species such as; Mucuna pruriens in L. rohita [61], N. sativa and nettle (Quercetin) extract in rainbow trout [78], and A. indica in Lates calcarifer [79].…”

“…In addition to serum glucose and cortisol concentration, neutrophils to lymphocytes ratio has been proven to be a valuable index to measure stress in invertebrates [41,57]. Studies have demonstrated that several plants such as Nigella sativa [58], A. sativum [59], Zingiber officinale [60], Pedalium murex [61], Melissa officinalis [31], and A. indica [62] are able to enhance some of these blood parameters, which is a denotation that plant extracts can indeed improve the health and immune system of fish.…”

“…Abdel-Tawwab et al [87] and Hwang et al [81] also reported that blood glucose increased in O. niloticus and Sebastes schegeli fed green tea extracts, respectively. On the contrary P. murex [61], A. sativum [88], and A. indica [79] revealed hypoglycemic and anti-hyperglycemic effects in L. rohita, L. calcarifer, and O. niloticus, respectively.…”

Effects of dietary <i>Aloe vera</i> crude extracts on digestive enzyme activities and muscle proximate composition of GIFT tilapia juveniles

“…For instance, dietary Astragalus membranaceus reportedly enhanced amylase and lipase activities, and subsequently improved feed conversion ratio, feed intake, weight gain and specific growth rate of Oreochromis niloticus juveniles (Zahran et al, 2014). In part, similar findings were observed in Labeo rohita juveniles when fed a diet supplemented with Mucuna pruriens extracts (Ojha et al, 2014), and Achyranthes aspera extracts (Vasudeva et al, 2006), respectively. In addition, improved survival rate, and disease resistance was reported in Ictalurus punctatus juveniles fed dietary Origanum vulgare extracts (Zheng et al, 2009), and in Cyprinus carpio fed dietary Rheum officinal extracts (Xie et al, 2008).…”

“…This lack of significant influence of dietary Astragalus on lipase activity in Nile tilapia seemed to be a result of a low intake of lipid from plant-related diets (Tengjaroenkul et al, 2000). El-Dakar (2015) reported that basil (Ocimum basilicum) extracts significantly increased serum lipase activity in Sparus aurata fingerlings, while protease activity was reported to increase significantly in Labeo rohita fingerlings after being fed with Mucuna pruriens ethanolic extracts (Ojha et al, 2014). Furthermore, based on the second-order polynomial analyses, the optimum dietary A. vera was estimated to be 1.76%, 1.82%, and 2.10% for amylase, trypsin, and lipase concentration, respectively.…”
