Replacement of Soybean Meal with Fermented Jatropha curcas Kernel Meal in the Diet of Labeo rohita Fingerlings: Effect on Hemato‐biochemical and Histopathological Parameters

Abstract

Jatropha kernel meal was detoxified through the process of solid‐state fermentation using Aspergillus niger fungus. A 60‐d feeding trial was conducted to evaluate the effects of replacing soybean meal (SBM) with fermented Jatropha kernel meal (FJKM) on the hemato‐biochemical and histopathological parameters in Labeo rohita fingerlings (average weight 6.05 ± 0.04 g). A total of 180 fish were randomly distributed in 12 experimental tanks in four dietary groups, namely control (SBM‐based diet), T1 (10% FJKM replacing 33.3% SBM), T2 (20% FJKM replacing 66.7% SBM), and T3 (30% FJKM replacing 100% SBM). There was no significant difference in the red blood cell, white blood cell, hemoglobin, total protein, albumin, globulin, and respiratory burst activity among the various groups, but significantly higher hematocrit value and albumin/globulin ratio were observed in the T2‐fed group compared with the control. No statistical difference was found in serum glucose level of the control and FJKM‐fed groups. Histopathological examination of the intestine and liver indicated no adverse effects in the control and FJKM‐fed groups. Our findings revealed that FJKM can replace 100% SBM protein in the diets of L. rohita fingerlings, without any adverse effects on fish health.

“…In this study, TP, ALB and the ALB/GLB ratio were not significantly affected by replacement of SBM by PSC (Table 4). Thus, these serum biochemical parameters were not negatively affected by the experimental treatments, which is in agreement with results from other studies (Çantaş & Yildirim, 2020;Diógenes et al, 2019;Phulia et al, 2017;Yuangsoi et al, 2014). The serum protein profile plays an important role in assessing the nutritional and health status of fish (Acar et al, 2015;Phulia et al, 2017).…”

Our findings indicate a similar nutritional and immunological status among groups, which is consistent with previous results on the replacement of dietary SBM with safflower meal and Jatropha curcas kernel meal in O. mykiss and Labeo rohita respectively (Çantaş & Yildirim, 2020;Phulia et al, 2017).…”

“…Although there are several studies on alternative feed ingredients, evaluation of affordable and locally available non‐conventional feed ingredients in fish diets is still necessary (Ayyat et al, 2021; Dernekbaşı et al, 2017; Mamuad et al, 2020). From this perspective, the impact of plant‐based, non‐conventional feed ingredients as protein sources has been evaluated in several fish species, for example, sesame seed meal (Dernekbaşı et al, 2017; Saleh, 2020), moringa seed cake (Yuangsoi et al, 2014), peanut meal (Wang et al, 2020), groundnut oil cake (Ghosh & Mandal, 2015), pigeon pea leafmeal (Rani et al, 2021), safflower meal (Çantaş & Yildirim, 2020), Jatropha curcas kernel meal (Phulia et al, 2017), distiller's dried grains with solubles (DDGS) (Aydın & Gümüş, 2020; Diógenes et al, 2019), faba bean meal (Li et al, 2020) and rubber seed meal (Deng et al, 2015).…”

“…One of the unexplored groups of protein sources is the non‐edible oilseeds. In the last few years, a significant number of protein‐rich non‐edible seed products have been tested in fish or shrimp feed either as partial or complete replacer of fishmeal or soybean meal (Fawole et al, ; Harter et al, ; Kumar, Makkar, & Becker, ; Phulia, Sardar, Sahu, Fawole, et al, ; Phulia, Sardar, Sahu, Sanap, et al, ; Phulia et al, ; Sanap et al, ; Shamna et al, , ).…”
