HYDRATED SODIUM CALCIUM ALUMINOSILICATE EFFECTS ON SOME MINERAL AND VITAMIN SlTATUS DURING AFLATOXICOSIS IN GROWlNG TURKEY

An experiment was conducted to evaluate effects of hydrated sodium
calclum aluminosilicate (HSCAS) and aflatoxin (AF) without or with adde~ minerals
and vitamins on tuf1(ey performance. apparent mineral retention, tissues ~mponenl
and AFB1 residues. A total number of 420 unsexed day old White Holla d turkey
chlds were divided into 12 groups (5 replicates of 7 chicks each). Three factors of the
feeding program were investigated in a factorial (3x2l112) arrangement Three levels (0.
0.5, 1%) of HSCAS and two levels (0, 1.25 ppm) of AF without or with added 0.25%
calcium (Ca). 0.13% available phosphorus (AP), 20 ppm zinc (Zn). 20 ppm
manganese (Mn) and Vitamin A (1200 IUlkg) were incorporated into practical com-
soybean meal basal diet and fed from 1 to 35 days old. The results obtained Indicated
that adding AF singly to basal diet showed many effects (P < 0.05 or 0.01), it
decreased body gain (28%), feed intake (15%). bursa of Fabricius and thym s glands

liver. and also vitamin A content in liver were decreased (P < 0.05 or 0[01). The
effects or 1% HSCAS were more severe (P < 0.05) than those or 0.5%. whie adding
AF with HSCAS diets had not altered (P -e 0.05) these effects of HSCAS. Raising level
of studied minerals and vitamin A with basal diet had negative effect, but these added
nutrients with HSCAS diets negated all advel'6e effects occurred by bo levels of
HSCAS on Zn, Mn and vitamin A stalus. Both ash. Ca, P apparent retention and their
contents in tibia and serum were unaffected (P < 0.05) In the present study .Iit can be
concluded that although the recommended 0.5% HSCAS for binding AF ~naltered
turkey growth performance values, raising level of some minerals and vita~ins with
HSCAS diets is very essential to campensate the deficiencies of these nutrients
utilization.
