Effect of Gliricidia sepium (Jacq) Leaf Meal Supplemented with Enzymes (Roxazyme® G2 and Maxigrain®) on Growth Performance of Clarias gariepinus Burchell, 1822

Abstract

The growth performance of Clarias gariepinus Burchell, 1822 fed Gliricidia sepium leaf meal and supplement with enzymes (Roxazyme®) and Maxigrain® were examined. The fingerlings having weight of about 6.34±0.43 g were stocked in12 plastic aquaria with 50 liters capacity at the rate of 25 juvenile per aquarium and fed on four different dietary treatments for 42 days. The experimental diets varied with increasing levels of G. sepium leaf meal, 0%, 10% without enzyme supplementation, 10% supplemented with enzyme (Roxazyme G2), and 10% supplemented with enzyme (Maxigrain). The growth performance, Feed Conversion Ratio (FCE) and water quality were evaluated during and by the end of trial. The results showed that all experimental treatments promoted positive growth and no mortality was encountered during the experimental period.

Effect of alternative protein blends on Oreochromis niloticus (Nile Tilapia) fingerlings’ growth performance, nutrient utilization and carcass characteristics

“…When compared to fresh leaves, tannins can be reduced by 15-30% through drying, fermenting, and silaging processes (Henry et al 2015). African cat sh and Nile tilapia both responded favorably to moringa at inclusion levels of 10-15 percent (Elabd et al 2019, Olopade et al 2015). (Billah et al 2020).…”

“…Methionine supplements in the diet have been shown to reduce the negative effects of antinutrients in sh by deactivating the saponin in the food and thereby improving the nutritional composition (Edoh et al 2019). It has been reported to have a positive impact on African cat sh (Olopade and Lamidi, 2015), Cirrhinus mrigala (Vhanalakar & Muley, 2014) and Nile Tilapia (Adeparusi &Agbede, 2005).…”

APLIKASI KOMBINASI TEPUNG DAUN GAMAL DAN TELUR PADA PAKAN KOMERSIAL TERHADAP KUALITAS PAKAN DAN EFISIENSI PAKAN IKAN NILA NIRWANA (Oreochromis niloticus)

“…Daun gamal adalah salah satu bahan baku nabati lokal yang dapat dijadikan sebagai bahan alternatif dalam meningkatkan protein pakan. Daun gamal merupakan hijauan pakan yang ketersediaannya melimpah dan mudah ditemukan di Aceh, serta masih memiliki kandungan nutrisi tinggi berdasarkan berat kering sebesar 16,88 % protein, 16,97 % serat kasar, 10,37 % kadar abu, 0,20 % kalsium, 0,40 % kadar fosfor dan energi kotor 3,01 % (Olopade et al, 2015). Namun, pemanfaatan daun gamal sebagai bahan baku pakan memiliki faktor pembatas berupa serat kasar yang masih tinggi dan terdapat kandungan zat anti nutrisi, sehingga diperlukan penggunaan teknologi fermentasi sebagai upaya untuk meminimalkan serat kasar dalam bahan baku dan meningkatkan kandungan nutrisinya.…”

“…Hal ini diduga karena aplikasi kombinasi tepung daun gamal dan telur pada pakan komersial mampu meningkatkan kadar protein pakan karena adanya penambahan protein yang terkandung dalam tepung daun gamal dan telur. Menurut Olopade et al (2015), daun gamal memiliki kadar protein berdasarkan berat kering sebesar 16,88 %. Telur ayam mengandung protein pada kuning telur sebanyak 16.5 % dan pada putih telur sebanyak 10,9 % (Sudaryani, 2008).…”

Effect of Gamal Leaves Extract (Gliricidia sepium) on Growth Rate and Feed Conversion Ratio of Bileh Fish (Rasbora sp.)

“…Gliricidia sepium contains 20-30% crude protein, 15% crude fiber, and 60-65% digestibility [9]. Olopade et al, [10] reported that gamal leaves contain protein = 16.88%, crude fiber = 16.97%, ash content = 10.37%, calcium = 0.20%, phosphorus content = 0.40%, and gross energy of 3.01% based on dry weight. The results of the research by Apriani et al, [11] reported gamal leaves added in artificial feed (75% gamal leaves and 25% commercial feed) had an effect on the growth of gouramy fry and could reduce the use of commercial feed.…”
