Abstract

<abstract abstract-type="main" id="anu12036-abs-0001"> <title>Abstract</title> <p>This study compared the nutritional profiles of menhaden fishmeal and pink salmon (<italic>Oncorhynchus gorbuscha)</italic> testes meal and investigated the nutritional values of the testes meal based on its effect on palatability, digestibility and growth performance of Pacific white shrimp <italic>(Litopenaeus vannamei)</italic>. The testes meal replaced 0–91% of fishmeal protein in a control diet containing 150 g kg⁻¹ fishmeal. Replacement of 69% of the fishmeal protein in the control diet significantly increased feed intake of shrimp from 0.61% to 1.10%. The apparent digestibility coefficient of dietary protein increased significantly when 91% of the fishmeal protein was replaced by the testes meal. Replacement of dietary fishmeal protein with up to 46% testes meal protein did not cause adverse effects on growth rate or nutritional composition of tail muscle. However, growth rate was significantly decreased in shrimp fed diets in which 69% or 91% of fishmeal protein was replaced by the testes meal. Results of this study indicate that the testes meal can be used as a feed additive to enhance the palatability and protein digestibility of low fishmeal diets for shrimp. It can replace up to 46% of fishmeal protein without any adverse effect on the growth performance of shrimp.</p> </abstract>
