    Abstract Background The present study investigated the effect of dietary Parkia biglobosa pulp (PBP) on the growth performance and blood profile of mixed sex Clarias gariepinus. The PBP meal was supplemented with the basal diets at 0.0, 0.5, 1.0, 1.5 or 2.0% and fed to C. gariepinus fingerlings for 12 weeks. Results Supplementing the diets of C. gariepinus with 1.0–2.0% PBP enhanced (P < 0.05) the weight gain, specific growth rate, protein efficiency ratio and reduced (P < 0.05) feed conversion ratio with the highest performance at 2.0% inclusion level, compared to the control diet. The red blood cell counts of the fish fed PBP-supplemented diets did not differ (P > 0.05) from those fed the control diet while the lymphocyte counts was boosted (P < 0.05) with dietary PBP. Dietary supplementation with 1.0–2.0% PBP enhanced (P < 0.05) synthesis of total protein and albumin in the experimental fish while all fish fed PBP-supplemented diets had lower (P < 0.05) levels of aspartate aminotransferase and alanine aminotransferase. Conclusions The present study showed that 1.0–2.0% PBP enhanced growth and nutrient utilization, lymphocytes, serum albumin and total protein and reduced serum liver enzymes, indicating the growth-promoting, immunostimulating and hepatoprotective effects of PBP in C. gariepinus Therefore, supplementation of PBP meal as feed additive in the basal diet of Clarias gariepinus at 2.0% is recommended.

    The global criticism on the adverse effects of synthetic antibiotics including destabilization of gut microflora necessitated research into natural alternative like phytobiotics. Tamarind pulp is a phytobiotic known for its antimicrobial, growth-promoting and antioxidants properties, with little information on the mechanism of its growth promotion in fish. Therefore, this study investigated the effects of tamarind pulp (TP) meal as feed additives on the growth, gut microflora, and morphometry in Clarias gariepinus. The fish were fed with diets fortified with graded levels (0.0%, 0.5%, 1.0%, 1.5% or 2.0%) of TP or 0.2% oxytetracycline (OTC). Fish weight gain, feed conversion ratio (FCR), gut microflora and morphometry were determined. The weight gain of fish rose (P 0.05) with increasing levels of TP, while the FCR reduced significantly, compared to those fed the control diets. The total viable counts and enterobacteriaceae from the gut of fish fed OTC-fortified control diet was lower, compared the fish fed unfortified control (0.0% TP) diet and diets containing TP. Fish fed 1.0-2.0% TP-fortified diets had significantly higher yeast counts, compared to those fed other diets, while on the other hand higher (P0.05) Streptococcus sp was obtained from fish fed the control diets. The thickness of muscular lining of the base of villi, villi height and absorption area were higher (P ˂ 0.05) in fish fed OTC-fortified (C2) diet, compared to other treatments, while lower crypt depth were obtained in fish fed TP-fortified diets. The correlation analyses showed moderate negative (R = -0.539 at P 0.05) relationship between FCR and population of enterobacteriaceae while a very strong positive relationship (R = 0.848 at P 0.01) existed between FCR and population of haemolytic Streptococcus. The enhanced growth in fish fed TP-fortified diets could be accredited to the reduced crypt depth and colonization of yeast and reduced Streptococcus counts. Therefore the application of tamarind pulp meal at 2% is recommended for enhanced growth and healthy gut microflora composition.
