Abstract

SUMMARY
Thirty two Rahmany male lambs averaged 5 - 6 months old and 22.13 kg live
body weights (LBW) were used in this study which lasted for 120 days. Their diet
was found naturally contaminated. Analysis found that concentrate feed mixture
(CFM) contained 163.24 μg /kg DM aflatoxin B1(AFB1) and 371.08 μg/kg DM
Ochratoxin A (OA), while clover hay (CH) had 26.2 μg AFB1/kg DM and free of
OA. The study aimed to examine the possibility to modify their toxic effect by
supplementing contaminated ration (60% CFM and 40% CH) as control group (R-
1), or with medicinal herbs mixture at rate 0.2% (R-2), Dtox (anti-toxin compound)
at rate 0.2% (R-3) or raw Bentonite at rate 2% (R-4). Each of the four groups was 8
lambs.
Supplemented ration with Detox or Bentonite (R3 & R4) increased
significantly (P<0.05) the digestibility of DM more than Medicinal herbs mixture
or control group (R2 & R1). Feed conversion ratio and economical efficiency
decreased significantly (P<0.01) by feeding lambs toxificated ration (R1). Feeding
lambs the control contaminated ration (CR) decreased significantly (P<0.05)
concentrations of serum total protein, albumin, globulin and amino-transaminase
enzymes, while increased significantly (P<0.05) serum urea-nitrogen and creatinine
concentrations comparable to the three treated rations.
It is concluded that adding 0.2% medicinal herbs mixture, was superior in
detoxification than adding Detox or Bentonite to the contaminated rations of
growing sheep. All could improve digestibility coefficients, average daily gain and
both feed and economical efficiencies. It could also increased excretion of AFB1
and OA in feces.
