Impact of some feed additives on Zaraibi goats performance and blood profile fed Aflatoxin contaminated diets
Abstract: Thirty five growing male Zaraibi kids aged about 100 days and weighed in average 14.41±2.45 kg, were divided according to their live body weight (LBW) into five similar groups (7 animals each). The diet fed was naturally contaminated with Aflatoxin (AFr^) 15.98 ug/kg DM in concentrate feed mixture (CFM) and 103.27 ug AFE^/kg DM in clover hay (CH). Kids were distributed according to body weight into 5 similar groups, that received 5 dietary treatments, Gl: diet naturally contaminated with AFB[ (control), G2: control +1 % Hydrated sodium calcium aluminosilicate (HSCA), G3: control +1 % HSCA +1 % Propionic acid (PA), G4: control +1 % HSCA + 0.5% gentian violet (GV) and G5: control +1 % HSCA + 0.5% GV + 1 % PA. The feeding experiment lasted for 120 days. The digestibility coefficients values of CP, CF, EE, NFE and feeding values of (R3, R4 and R5) diets were higher than that of
supplemented with HSCA or control diets (R2 & Rl). Contaminated-diet plus 1% HSCA+ 0.5 % GV + 1% PA,
recorded higher digestibility coefficients values for all nutrients especially CP, EE and NFE than the other diets.
Average DM intake expressed as daily DM intake or TDN and DCP% was significantly higher (PO.05) with kids fed diet supplemented with HCAS + 0.5% GV+ PA (R5), followed by HCAS (R2), HCAS + PA (R3) and HCAS+ GV (R4) than those fed the control diet (Rl). The average daily gain (ADG) was significantly (P<0.05) increased inZaraibi kids treated rations (R2, R3, R4 and R5) than those fed the control ration (Rl). In addition, using HSCA alone either with propionic acid or gentian violet improved ADG by about 43.06, 47.75, 46.64 and 52.24%, respectively. Feed efficiency expressed as DMI and/kg gain, was better (P<0.05) in kids received treated diets with HSCA+ GV. +propionic acid(R5), followed by HSCA + PA (R3), HSCA + GV. (R4) and R2 (HSCA), respectively, than Rl. Serum total protein (STP), albumin and globulin of R2,R3,R5 andR5 had a significant (P<0.05) higher values than control diet,
significant increase (P<0.05) in the mean values of serum transaminases activities (ALT & AST), urea-N, creatinine and Cholesterol concentrations, for growing Zaribi kids fed the contaminated diet (Rl) compared to kids fed contaminated diets plus HSCA (R2) or HSCA plus PA (R3), HSCA + GV (R4) or diet with HSCA + GV + PA (R5).
The results of hematological parameters, indicated that the values of hemoglobin (Hb), red blood cells (RBC's), MCH,
MCHC and lumphocytes cells were reduced with contaminated diet (Rl) than in the other treatment groups and the differences were significant in Hb, RBC's and lymphocytes. It is concluded that adding 1% Hydrated sodium calcium alumino-silicate (HSCA), 1% Propionic acid (PA) and 0.5% gentian violet (GV), was superior in detoxification than adding additives to the contaminated rations growing male Zaraibi kids. All could improve digestibility coefficients, average daily gain and both feed efficiencies.
