| Abstract | ||
| The aim of this study was to evaluat the ability of Lactobacillus casei and Lactobacillus acidophilus in counteracting the deleterious effects of aflatoxin B1(AFB1) in broiler chickens .One hundred and fifty Ross 308, one-day-old broiler chicks were assigned 10 treatments, 3 replicates with 5 birds cages each for 42 reaed day. The experimental treatments were labeled as follows :-T1. BD no other addition (Control ).T2. BD containing a 3 mg FB1/kg diet .T3. BD + Lactobacillus casei CFU ( 1.5×108 cell /ml live).T4. BD + Lactobacillus acidophilus CFU ( 1.5×108 cell /ml live).T5. BD containing a 3 mg AFB1/kg diet + Lactobacillus casei CFU ( 1.5×108 cell /ml live) .T6. BD containing a 3 mg AFB1/kg diet+ Lactobacillus acidophilus CFU( 1.5×108 cell /ml live).T7. BD + Lactobacillus casei CFU( 1.5×108 cell /ml dead).T8. BD + Lactobacillus acidophilus CFU ( 1.5×108 cell /ml dead).T9. BD containing a 3 mg AFB1/kg diet + Lactobacillus casei CFU ( 1.5×108 cell /ml dead).T10. BD containing a3 mg AFB1/kg diet+ Lactobacillus acidophilus CFU ( 1.5×108 cell /ml dead). Growth performance and serum biochemical parameters was measured from d21 and 42 organs weight were determined on d42of age. Aflatoxin B1 significantly decreased BW-gain ,feed intake and impaired feed conversion rate (p˂0.05) at both periods 21 and 42 days and increased relative organs weight (heart,liver,spleen and gizzared) and decreased fabritia and totha. The supplementation of L. casei or L. acidophilus to aflatoxin B1 treated birds significantly diminished the inhibitory effects of dietary AFB1 (p˂0.05) on the growth performance with no differences compared to the control diet. In conclusion our results showed that addition of L. casei and L. acidophilus may reduce the adverse effects produced by the presence of AFB1 in broiler chickens diet. | ||
