Abstract

ABSTRACT This study evaluated growth responses of white shrimp Litopenaeus vannamei by testing different combinations of Jatropha curcas kernel meal (JCK) and tilapia waste silage (FS) as dietary protein sources under laboratory and pond conditions. A reference diet (RD) based on fish meal was elaborated to contain 35% crude protein and 434 kcal/g; then, five isoproteic and isoenergetic experimental diets were formulated from RD with different FS/JCK proportions as follows: 75%FS/0%JCK; 56.25%FS/13.25%JCK; 26.5%FS/30.89%JCK; 18.75%FS/39.75%JCK; and 0%FS/53%JCK. For the laboratory trial, [...]

This study reported growth responses of L. vannamei by adding different combinations of J. curcas kernel meal and fish waste silage as protein sources in shrimp diets, under laboratory and pond conditions
Protein was higher than 42% Crude protein (CP) for both Jatropha curcas kernel meal (JCK) and FS ingredients

Summary

Introduction

Fish meal (FM) has been the main source of dietary protein for fish and shrimp. Soybean meal (SBM) is currently the most commonly used plant protein source in fish feeds (Yue and Zhou, 2009), but its price has increased sharply. Jatropha curcas is a multipurpose and drought-resistant tree, widespread throughout the tropics and subtropics. It is a hardy plant, thrives on degraded land, and requires limited amounts of nutrients and water. The seed kernel contains about 60% oil that can be converted into high-quality biodiesel upon trans-esterification and used as a substitute for diesel fuel (Makkar et al, 2007). The kernel meal obtained after oil extraction is an excellent source of nutrients and contains 58-62% crude protein (Makkar et al, 2008). The presence of antinutrients such as trypsin inhibitor, lectin
