CHEMICAL AND BIOLOGICAL EVALUATION OF JOJOBA SEEEDS AND JOJOBA MEAL (Simmondsia chinensis) IN COMPARISON WITH SOME OTHER PLANT PROTEIN SOURCES.
Central Lab for Food and Feed, Orman, Giza, Egypt.
Abstract
Chemical and biological studies were carried out to compare three samples
ofj0jcba with soybean meal (SBM). sunflower meal (SFM) and rapeseed meal (RSV)
as plant protein sources The jojoba samples were jdjoba seed (J5), extracted
crushed jojoba seed meal (JMi) and extracted whole seed jdjoba meal (JMg)
Chemical evaluation, metabolizable energy assays, protein digestibility and amino
aCids pattern and availability were studied, The results of protein content of JS, JM‘”
JM;, SBM. $l and RSM were 14.18, 24 95, 31,29, 47 74, 38 39 and 35.22,
respectively Among the ten essential amino acxds assayed, the 1“ limiting amino acid
(LAA) in JMi and JM; was methionine and the 2nd was IySine Chemical score and
essential amino acid index (EAAI) for all tested materials were estimated The AME
values (KcaI/g DM) were 4.095, 3.153, 3.110. 2.494, 2.428 and 2.312 for JS. JMi, JME,
SBM, SFM and RSM, respectively. Coefficients of metabolized GE as well as some
relationships among four estimates of metabolized GE as well as some relationships
among four estimates of bioavailable energy were discussed
The mean values of Apparent amino acid availability (AAAA) were 67 42%,
71.99%, 76.49%, 82.58%. 84.50% and 75.37% for JS. JMi. JMz, SBM, SFM and RSM.
respectively, The mean values of True amino acid availability (TAAA) were 86 29%.
83 62%, 85.82%. 88.01%. 92.28% and 83.77% at the same order, respectively. The
apparent protein digestibility (APO) and true protein digestibility (TPD) for JM. and
.l recorded higher values than for JS, however, the values were nearly close to
those obtained with some other tested materials. The most important aspect that
should be taken into consideration in future work is the toxic compounds found in
jdjoba meal JOjOba meal should be detoxifed to be accepted as an ingredient n
poultry feed. It should be noted that no toxic effects appeared in the present work
because the birds were fed small amount of feed (359) for one time only in
conclusion, the jojoba meal, as a by-product ofjojoba seeds, is a promising feedstuff
after being detoxified
