The Nutritional Value Of Cassava (Manihot esculenta Crantz) Based Diet For African Catfish (Ciarias gariepinus).
Masters thesis, Universiti Sains Malaysia.
Abstract
Empat kajian telah dilaksanakan untuk mengetahui nilai nutrisi serbuk daun
ubi kayu (CLM) dan serbuk ubi kayu (CRM) ke arah membangunkan diet kos yang
efektif bagi ikan keli Afrika (Ciarias gariepinus). Nisbah protein haiwan kepada protein
tumbuhan dalam setiap eksperimen adalah sama iaitu 1 : 1. Eksperimen pertama
dijalankan untuk menilai kesan penggantian serbuk kacang soya (SBM) dengan CLM
secara berperingkat, terhadap penampilan anak ikan keli Afrika (1.45 g 2: 0.14). Empat
diet praktikal (30% protein) telah dirumuskan dengan setiap satunya mengandungi 0%,
10%, 20% dan 30% CLM. Selepas 12 minggu keputusan menunjukkan ikan keli yang
diberi makan diet yang mengandungi CLM mengalami kemerosotan pertumbuhan dan
penggunaan makanan serta keterhadaman protein berbanding yang menerima
rawatan diet kawalan.
Four studies to evaluate nutritional value of cassava leaf meal (CLM) and
cassava root meal (CRM) (Manihot esculenta Crantz) in order to develop a suitable
cost effective diet for African catfish ( Clarias gariepinus) was conducted. All
experimental diets were prepared with a 1 : 1 animal and plant protein ratio. The first
experiment was carried out to evaluate the effect of graded levels CLM at the
expenses of soybean meal (SBM) on African catfish fry (1.45 ±. 0.14) performance.
Four practical diets (30 % crude protein) were formulated to contain CLM at 0 %, 10 %,
20 % and 30 % levels. After 12 weeks, fish fed increasing levels of CLM showed
growth depression, poor feed utilization, apparent protein digestibility (APD) as well as
imbalance indispensable amino acid (IDAA) compared to the control diet.
