| Abstract |
An experiment was conducted to evaluate effects of hydrated sodium calcium aluminosilicate (HSCAS) and aflatoxin (AF) without or with added minerals and vitamins on turkey performance, apparent mineral retention, tissues component and AFB1 residues. A total number of 420 unsexed day old White Holland turkey chicks were divided into 12 groups (5 replicates of 7 chicks each). Three factors of the feeding program were investigated in a factorial (3x2x2) 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 IU/kg) were incorporated into practical corn-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 thymus glands weight (%), meat fat and glycogen contents, and blood hemoglobin, total proteins, total lipids and cholesterol constituents. While mortality rate, feed to gain ratio, relative liver (66%), kidneys and spleen weights, liver fat content (141%), and serum alanine aminotransferase (ALT) and aspratate aminotransferase (AST) activities were increased and there was AFB1 residues in meat (25.4 ng/g) and liver (93.4 ng/g) tissues for basal diet contained AF singly. Inclusion of 0.5 or 1 % HSCAS to AF diets diminished and recorded similar protections about 45-74% against AF effects on different traits cited above. While raising level of minerals and vitamin A with AF diets had a negative effect (P<0.05) on aflatoxicosis. Inclusion of HSCAS at both levels singly to basal diet unaltered (P < 0.05) growth performance values and tissues component, except Zn and Mn apparent retention and their contents in tibia, toe and liver, and also vitamin A content in liver were decreased (P < 0.05 or 0.01). The effects of 1 % HSCASwere more severe (P < 0.05) than those of 0.5%, while adding AF with HSCAS diets had not altered (P < 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 adverse effects occurred by both levels of HSCAS on Zn, Mn and vitamin A status. Both ash, Ca, P apparent retention and their contents in tibia and serum were unaffected (P < 0.05) in the present study. It can be concluded that although the recommended 0.5% HSCAS for binding AF unaltered turkey growth performance values, raising level of some minerals and vitamins with HSCAS diets is very essential to compensate the deficiencies of these nutrients utilization.
