Dietary inclusion effect of ginger (Zingiber officinale) and garlic (Allium sativum) blend on growth, feed nutrients utilization and retention in African Catfish (Clarias gariepinus) fry in intensive system Paulin Nyadjeu Noël Arlette Tamko Ndjuissi Doriane Divine Mane Yemdjie Nesrine Yolande Chamsy Dedou Georges Fonkwa Ghislain Nguimdop NguenangMinette Eyango Tabi-Tomedi<p>This study was conducted to evaluate the dietary inclusion effect of ginger-garlic mixture on growth, feed nutrient utilization and whole-body composition of Clarias gariepinus fry. Fry weighing 1.2±0.01g were divided into four triplicate treatments before being fed with diets containing 0mg (D0 or control), 50mg (D1), 100mg (D2) and 200mg (D3) of ginger-garlic mixture /kg diet (1:1 proportion) for 56 days. Fish were fed at the rate of 10% of their body weight and every 14 days, intermediate sampling was done during which fry per treatment were counted, measurements taken on a representative sample and the feeding rate adjusted. Main water parameters were recorded daily before feeding. The results obtained indicate that, adding ginger-garlic blend in the diet enhanced significantly growth, feed nutrients utilization and retention as well as whole-body composition of C. gariepinus fry depending to the inclusion level. Fish fed with the highest supplemented level (200mg/kg diet) have recorded a final weight of 25.5±0.16g, with a weight gain (WG) of 24.34±0.16g, feed conversion ratio (FCR) of 1.46±0.01 and protein efficiency ratio (PER) of 1.53±0.02. These parameters were significantly different to those recorded in fish fed with control diet (final weight=17.02±0.27g, WG=15.23±0.28g, FCR=2.03±0.01, and PER=1.10±0.01). Similar trend to growth parameters was observed with macro-nutrient retention (protein=36.2±0.33%, lipid=29.1±0.33%, ash=23.13±0.68% and energy=24.99±0.25%) as compared to control (protein=24.94±0.01%, lipid=21.91±0.01%, ash=13.40±0.01% and energy=18.00±0.01%) Thus, the improvement in growth induced by the feed addition of ginger-garlic mixture could be largely attributed to the synergistic actions of the bioactive molecules contained in each phyto-additive on the functioning of the digestive system as well as to their hypoglycaemic and antioxidant properties.</p> International Journal of Aquaculture and Fishery Sciences - Peertechz Publications 2021-05-27 Research Article https://doi.org/10.17352/2455-8400.000068 en Copyright © Paulin Nyadjeu et al.
